  • [Title] Germ cell tumors of the gonads: a selective review emphasizing problems in differential diagnosis, newly appreciated, and controversial issues.
  • Gonadal germ cell tumors continue to be the cause of diverse, diagnostically challenging issues for the pathologist, and their correct resolution often has major important therapeutic and prognostic implications.
  • They are academically interesting because of the biological diversity exhibited in the two gonads and variation in frequency of certain neoplasms.
  • The most dramatic examples of the latter are the frequency of dermoid cyst in the ovary compared to the testis and the reverse pertaining to embryonal carcinoma.
  • Within the teratoma group, there is strong evidence that ovarian and prepubertal testicular teratomas are derived from benign germ cells, a pathogenesis that likely applies also to the rare dermoid cysts and uncommon epidermoid cysts of the testis.
  • In contrast, postpubertal testicular teratomas derive from malignant germ cells, specifically representing differentiation within a preexistent nonteratomatous cancer.
  • As expected, given the foregoing, teratomas in boys are clinically benign, whereas in postpubertal males they are malignant, independent of their degree of immaturity.
  • On the other hand, immaturity is an important finding in ovarian teratomas, irrespective of age, although its significance in children has recently been challenged.
  • It is usually recognized on the basis of embryonic-appearing neuroepithelium, which shows mitotic activity and apoptosis in contrast to differentiated neuroepithelial tissues, which may occur in mature ovarian teratomas.
  • Further differences between the teratomatous tumors in the two gonads are the relative frequency of monodermal teratomas in the ovary in contrast to the testis, where only one subset, carcinoids, is seen with any frequency.
  • When uncommon somatic-type malignancies (usually squamous cell carcinoma) occur in mature cystic teratomas of the ovary, this is a de novo form of malignant transformation; similar tumors in the testis, a very rare event, represent overgrowth of teratomatous elements that originated from malignant, nonteratomatous germ cell tumors and, therefore, had previously undergone malignant transformation.
  • Germinomas may have several unusual features in each gonad; these include microcystic arrangements that suggest yolk sac tumor, tubular patterns that mimic Sertoli cell tumor, apparent increased cytological atypia that causes concern for embryonal carcinoma, and prominent syncytiotrophoblast giant cells that suggest choriocarcinoma.
  • A newly recognized aspect of this tumor is the propensity for some to be relatively monomorphic, making them apt to be mistaken for usual seminoma or embryonal carcinoma, although the characteristic polymorphic appearance in some foci, absence of intratubular germ cell neoplasia, unclassified type, and immunohistochemical stains should prevent this error.
  • The recently described marker, OCT3/4, a nuclear transcription factor, is especially helpful in the differential of germinoma and embryonal carcinoma with other neoplasms.
  • Yolk sac tumor continues to be confused occasionally with clear cell carcinoma of the ovary.
  • Glandular ('endometrioid-like') yolk sac tumors mimic endometrioid carcinomas; predominant or pure hepatoid yolk sac tumors cause concern for metastatic hepatocellular carcinoma or, in the ovary, primary hepatoid carcinoma, and solid patterns, especially in limited samplings, may be misinterpreted as germinoma.
  • The usually younger age of patients with yolk sac tumors helps with the differential considerations with the nongerm cell tumors, as do other clinical and microscopic features and selected immunohistochemical stains.
  • Choriocarcinoma is rare in both gonads, and those in the ovary must be distinguished from metastatic tumors of placental origin.
  • Syncytiotrophoblast cells alone, admixed with other forms of germ cell tumor, still are confused with choriocarcinoma, but this phenomenon, which is much more frequent than choriocarcinoma, lacks the plexiform arrangement of different trophoblast cell types that typifies the latter.
  • Mixed germ cell tumors (which may show almost any combination of components) are common in the testis but rare in the ovary.
  • A separately categorized, rare form of mixed germ cell tumor seen in both gonads is the polyembryoma.
  • It is perhaps the most photogenic of all gonadal germ cell tumors and is also intriguing because of its distinctive, organized arrangement of yolk sac tumor and embryonal carcinoma elements and recapitulation of very early embryonic development, even to the extent of having in its fundamental unit, the embryoid body, a miniature yolk sac, and amniotic cavity.
  • These tumors, which are constituted by innumerable embryoid bodies, almost always contain teratomatous glands in minor amounts, and one way of viewing the polyembryoma is to consider it the most immature form of teratoma.
  • Embryoid bodies are also common as a minor component of many mixed germ cell tumors, particularly in the testis, and the diffuse embryoma is another variant that has a particular arrangement of yolk sac tumor and embryonal carcinoma elements.
  • Regression of gonadal germ cell tumors is a phenomenon restricted to the testis, for unknown reasons.
  • These so-called 'burnt-out' germ cell tumors can be recognized by a distinctive constellation of findings, including sometimes minor foci of residual recognizable germ cell neoplasia, a well-defined zone of scarring (often having residual ghost tubules), associated lymphoplasmacytic infiltrate, intratubular calcification and, in about 50%, of in situ germ cell neoplasia.

2. Kline RC, Bazzett-Matabele LB: Adnexal masses and malignancies of importance to the colorectal surgeon. Clin Colon Rectal Surg; 2010 Jun;23(2):63-71

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In this article, the authors review both benign and malignant ovarian masses, as the colorectal surgeon who encounters an adnexal mass at the time of surgery should be aware of the steps necessary for surgical staging and optimal tumor resection.Ovarian tumors-most of which are benign-are divided into three major categories, in order of frequency: epithelial, germ cell, and sex cord-stromal tumors.
  • Nonneoplastic conditions of the ovary that may present as adnexal masses include the following, according to World Health Organization (WHO) classification: pregnancy luteoma, hyperplasia of ovarian stroma, hyperthecosis, massive edema, solitary follicle cysts and corpus luteal cysts, multiple follicle cysts, and endometriosis.Epithelial ovarian tumors arise from the surface epithelium and can be benign or malignant.
  • Histologic types are serous, mucinous, endometrioid, clear cell, or Brenner.
  • Germ cell tumors are more likely to appear in females under 20 years, accounting for 70% of ovarian tumors in this age group.
  • Teratomas are the most common germ cell tumors.
  • Malignancies, in addition to malignant teratomas, include dysgerminomas, endodermal sinus tumors, and embryonal carcinomas.
  • The more common sex cord-stromal tumors include granulosa stromal cell tumors, Sertoli-Leydig cell tumors, and gynandroblastomas.Surgical staging and optimal tumor resection are also addressed, with a focus on epithelial malignancies, as they are the most relevant to colorectal surgeons.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Primary ovarian leiomyoma associated with endometriotic cyst presenting with symptoms of acute appendicitis: a case report.
  • BACKGROUND: Ovarian leiomyoma is a rare benign tumor that accounts for 0.5 to 1% of all benign ovarian tumors.
  • It probably arises from smooth muscle cells in the ovarian hilar blood vessels but there are other possible origins including cells in the ovarian ligament, smooth muscle cells or multipotential cells in the ovarian stroma, undifferentiated germ cells, or cortical smooth muscle metaplasia.
  • Additionally, smooth muscle metaplasia of endometriotic stroma, smooth muscle present in mature cystic teratomas, and smooth muscle in the walls of mucinous cystic tumor may explain their occurrence in the ovary in some cases.
  • Upon laparotomy, there was a solid, oval left-sided ovarian tumor located behind the uterus.
  • The tumor was sent to the pathology department.
  • A diagnosis of primary ovarian leiomyoma associated with an endometriotic cyst was established.
  • CONCLUSION: The origin of ovarian leiomyoma is still unresolved.
  • In our case, the tumor probably arose from smooth muscle cells derived from myofibroblasts that originate from metaplastic ovarian stromal cells present in the rim of the endometriotic cyst.
  • Despite its rarity, ovarian leiomyoma should be considered in the differential diagnosis of ovarian spindle cell tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Transient bilateral ovarian enlargement associated with large retroperitoneal lymphoma.
  • Bilateral ovarian enlargement may reflect benign or malignant processes of the ovary.
  • Benign causes of ovarian enlargement include luteomas, tumors such as mature cystic teratomas, fibrothecomas, cystadenomas and rare conditions including capillary hemangioma and massive edema of the ovaries.
  • Ovarian malignancies include epithelial, stromal and germ-cell tumors.
  • Primary malignancies that may exhibit metastases to the ovaries include gastrointestinal, breast and soft tissue tumors such as lymphoma.
  • We present an unusual case in which a patient presenting with weakness and mild lower abdominal and pelvic pain was noted at sonography to have bilaterally enlarged ovaries with features similar to those of massive ovarian edema as described previously, which has been associated with venous and lymphatic obstruction.
  • Subsequent computerized tomography (CT) imaging depicted a large retroperitoneal tumor, CT-guided biopsy of which revealed diffuse large B cell lymphoma.
  • The patient responded well to chemotherapy with significant shrinkage of the tumor, and reappearance of normal findings on ovarian sonography.
  • This case demonstrates that bilaterally enlarged ovaries may be the first clinical evidence of a large retroperitoneal tumor and that in such cases CT imaging may be warranted.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Analysis of ovarian teratomas for isochromosome 12p: evidence supporting a dual histogenetic pathway for teratomatous elements.
  • Teratomas are the most common germ cell tumor (GCT) of the ovary and include several types with a range of clinical behavior.
  • As in testicular teratomas, they may be benign, malignant or a component of a mixed GCT.
  • In the testis, data support separate pathogeneses for prepubertal and postpubertal teratomas, with derivation of the former from a nontransformed germ cell and the latter from differentiation of a nonteratomatous, malignant GCT.
  • The absence of cytogenetic abnormalities (including isochromosome 12p (i(12p)) in mature ovarian teratomas suggests that they may be analogous to prepubertal testicular teratomas, but there are no data regarding genetic changes in the teratomatous components of ovarian mixed GCTs.
  • We therefore studied the teratomatous components of six mixed GCTs of the ovary using fluorescence in situ hybridization (FISH) for i(12p).
  • Six mixed GCTs of the ovary occurred in patients 4-33 years of age; all had teratomatous and yolk sac tumor components and three also contained foci of embryonal carcinoma.
  • By comparison, five pure, mature ovarian teratomas and three pure, immature ovarian teratomas showed no evidence of either i(12p) or other forms of 12p amplification.
  • These findings support that teratoma in mixed ovarian GCTs has a different pathogenesis compared to pure teratoma of the ovary.
  • Furthermore, the findings of i(12p) in both the teratomatous and nonteratomatous components of ovarian mixed GCTs supports that the teratoma derives from other components, similar to the situation in the testis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ovarian germ cell tumors in children: a clinical study of 66 patients.
  • BACKGROUND: Ovarian germ cell tumors are rare in childhood.
  • The aim of this study is to review clinical presentation, management, and outcome in a two-center series of girls with ovarian germ cell tumor.
  • PROCEDURE: The records of 66 patients (median age 9 years) with histologically proven ovarian germ cell tumor (either benign or malignant), treated over a 44-year-span, were reviewed.
  • The tumors were right-sided in 35, left-sided in 28, and bilateral in 3.
  • Sixteen patients had an emergency operation for tumor torsion.
  • Unilateral salpingo-oophorectomy was the most frequently performed procedure (n = 46), and ovarian-sparing tumorectomy was performed in 9 patients (one bilaterally).
  • Histologically, teratomas were found most frequently (mature: 45, immature: 9), followed by mixed tumors (n = 7), yolk sac tumors (n = 3), dysgerminoma (n = 2), gonadoblastoma (n = 2), and embryonal carcinoma (n = 1).
  • Surgical removal of the tumor with or without the ovary and/or adnex was the sole treatment in 55 patients, chemotherapy was administered in 10 and radiotherapy + chemotherapy in one.
  • CONCLUSIONS: With a recurrence rate of 4.5% and a mortality rate of 3%, this series confirms the excellent prognosis for girls with ovarian germ cell tumor (GCT).

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Oncofetal protein glypican-3 distinguishes yolk sac tumor from clear cell carcinoma of the ovary.
  • Clear cell carcinoma (CCC) of the ovary is the surface epithelial neoplasm most often confused with primitive germ cell tumors, particularly yolk sac tumor (YST) and dysgerminoma.
  • Recent studies suggest that glypican-3 (GPC3), an oncofetal protein expressed in fetal liver and malignant tumors of hepatocytic lineage, is also expressed in germ cell tumors, particularly YST.
  • To investigate whether GPC3 is useful in distinguishing YST from ovarian CCC, we studied the expression of GPC3 in a large series of ovarian neoplasms and compared it to the expression profiles of CK7 and alpha-fetoprotein.
  • Tissue microarrays containing over 400 benign and malignant ovarian neoplasms, including 34 CCCs were stained with monoclonal GPC3 (clone 1G12, Biomosaics, Burlington, VT).
  • These arrays contained a wide assortment of ovarian surface epithelial neoplasms and sex cord stromal neoplasms, as well as germ cell tumors.
  • All but one YST (97%), including those associated with mixed germ cell tumor were positive for GPC3, whereas all teratomas and embryonal carcinomas were negative.
  • The syncytiotrophoblastic cells in the germ cell tumors and placental villi included in the arrays were also positive for GPC3.
  • Most CCCs (83%) were completely negative for GPC3, as were 99% serous, 94% endometrioid, and 100% mucinous tumors.
  • All other tissues, including normal ovary were negative for GPC3.
  • GPC3 seems to be a promising diagnostic marker for differentiating YST from ovarian CCC (P < 0.0001).

  • [Title] Expression of galectin-3 in gonads and gonadal sex cord stromal and germ cell tumors.
  • Galectin-3, a beta-galactoside-binding lectin, has been implicated in many human malignancies, but has seldom been studied in human gonads and gonadal tumors.
  • The aim of our study was to investigate galectin-3 mRNA and protein expression in normal ovaries and testes as well as in a variety of 51 gonadal sex cord stromal and germ cell tumors, and two testicular seminomatous and non-seminomatous cell lines, using either real-time PCR or immunohistochemistry.
  • In human ovaries, galectin-3 is absent from granulosa cells, as well as from granulosa cell and Sertoli-Leydig cell tumors, and is not a useful marker in distinguishing granulosa cell from Sertoli-Leydig cell tumors.
  • In testicular tumorigenesis, galectin-3 has a dual function according to the histological type of tumors and their hormone dependency.
  • In malignant testicular Sertoli cell tumors, the expression of galectin-3 is down-regulated while, in benign Leydig cell tumors, this expression is maintained, indicating the possible implication of this gene in the development of more aggressive testicular sex cord stromal tumors.
  • In contrast to sex cord stromal tumors, galectin-3 expression is up-regulated in testicular germ cell tumors.
  • By real-time PCR, we demonstrated a significant elevation of the galectin-3 mRNA level in non-seminomatous testicular germ cell tumors and cell line as compared to normal testes and seminomas (p=0.0432 and p=0.0247, respectively), indicating the possible role of this gene in the non-seminomatous differentiation of germ cell tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Juvenile granulosa cell tumor of the ovary presenting with pleural effusion and ascites.
  • Juvenile granulosa cell tumor (GCT) is a rare tumor, and the majority (90%) are reported in the prepubertal or under-30-year age group, in contrast to the adult type, which is more common in the fifth decade.
  • Being solid tumors, they may be associated with ascites and pleural effusion (Meigs' syndrome), which resolve after surgical removal of the tumor.
  • Tumor markers for GCT are still investigational (inhibin) and of not much use in making a preoperative diagnosis, unlike in the case of germ cell tumors.
  • However, lymph node sampling is advocated for complete staging of these tumors, as a significant number of recurrences are reported in the retroperitoneum, as well as in incompletely staged patients.
  • In the present patient, because of the association of Meigs' syndrome, a preoperative diagnosis of benign tumors such as fibroma/thecoma was also considered.
  • We report this rare tumor with an aim of reviewing the diagnosis and management from the reported literature.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [Teratoma of the ovary. Clinical and pathological differences between mature and immature teratomas].
  • Teratomas are the most frequent germ cell tumors of the ovary.
  • Mature teratomas are benign tumors, which are most often composed of derivatives of two or three germ cell layers.
  • Only in rare cases is the transition into a malignant tumor observed (most often squamous cell carcinoma).
  • In contrast, immature teratomas are malignant ovarian tumors.
  • Histologically, this tumor component can be identified as neurotubules or rosettes.
  • In childhood cases, foci of yolk sac tumor (YST) must be looked for, since this determines the prognosis.
  • Gliomatosis peritonei is most likely derived from metaplasia of subperitoneal stem cells; it does not represent a metastatic disease of the ovarian teratoma.

  • This study investigated the expression patterns of Müllerian inhibiting substance/anti-Müllerian hormone type II receptor (MIS/AMHRII) and mRNA in various types of ovarian neoplasia and evaluated the clinical significance of MIS/AMH as a biological response modifier for MIS/AMHR-positive tumors.
  • There was no significant difference in expression intensity between MIS/AMHRII protein and mRNA on all ovarian samples whether benign or malignant.
  • MIS/AMHRII protein and mRNA were weakly expressed on 45.45% of benign ovarian tumors.
  • In borderline tumors, expression rates of MIS/AMHRII protein and mRNA were 77.78% with score 1.22 and 55.56% with score 1, respectively.
  • In malignant ovarian tumors, expression rates of MIS/AMHRII protein and mRNA were 70% with score 1.23 and 75% with score 1.43, respectively.
  • Among malignant ovarian tumors, sex cord stromal tumors showed the highest expression rate and the strongest intensity of MIS/AMHRII protein and mRNA followed by germ cell tumor and epithelial ovarian tumor.
  • Non-epithelial malignant tumors showed stronger expression than that of epithelial tumors (P<0.05, P<0.001, respectively).
  • In serous borderline malignant and malignant tumors, MIS/AMHRII protein and mRNA expression was 63.64 and 81.82% with expression intensity of 1.27 and 1.46, respectively, which were not statistically different from non-epithelial malignant tumors.
  • MIS/AMHRII and MIS/AMHRII mRNA demonstrate significantly variable expression among different ovarian tumor types.
  • Non-epithelial cell tumors show higher expression than those of epithelial cell tumors.
  • The highest expression rate and intensity were observed on sex cord stromal tumors.
  • These data support that MIS/AMH may be used as a biological modifier or therapeutic modulator in MIS/AMHRII-expressed ovarian tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] A case of sebaceous carcinoma arising within a benign ovarian cystic teratoma.
  • BACKGROUND: Mature cystic teratoma, also known as dermoid cyst, is the most common germ cell tumor of the ovary.
  • Malignant change in a component of a mature ovarian teratoma is rare, occurring in less than 2% of cases, with squamous cell carcinoma corresponding to 80% of such neoplasms.
  • Abdominal and pelvic ultrasound as well as computed tomography demonstrated a heterogenic tumor of the right ovary.
  • Histological examination of the tumor showed features of a well-differentiated sebaceous carcinoma arising within a mature cystic teratoma.
  • CONCLUSIONS: This is an extremely rare ovarian malignancy of which the clinical behavior and optimal management are not well established.
  • Differential diagnosis with other malignant neoplasms arising in mature cystic teratomas is exceedingly important for treatment and prognosis.

  • [Title] Transitional cell metaplasia of fallopian tube fimbriae: a potential mimic of early tubal carcinoma in risk reduction salpingo-oophorectomies from women With BRCA mutations.
  • Germline mutations in the hereditary breast/ovary carcinoma genes BRCA1 or BRCA2 confer increased lifetime risk for ovarian, fallopian tube, and primary peritoneal carcinoma.
  • Transitional cell metaplasia is a benign epithelial alteration that is a common finding in the serosa of the tube but is underrecognized in the tubal fimbriae, where it may mimic tubal intraepithelial carcinoma.
  • The aim of this study was to define the incidence, morphology, immunophenotype, and distribution of transitional cell metaplasia of the fimbriae in RRSO specimens from 96 women with BRCA germline mutations and to compare these features to those of tubal intraepithelial carcinoma in this cohort.
  • RRSO specimens from an additional 30 women at increased risk for ovarian cancer based on strong family history were also studied, along with RRSO from 1 patient with Lynch syndrome, and 1 patient with PTEN mutation.
  • Transitional cell metaplasia of the fimbriae was present in 26% of all RRSO specimens.
  • Median tumor size was 2.7 mm (range: 1 to 11 mm).
  • The key criteria distinguishing transitional cell metaplasia from tubal intraepithelial carcinoma were uniform cell size and shape, normal nucleus:cytoplasm ratios, lack of nuclear atypia, presence of nuclear grooves, lack of mitoses, and absence of p53 expression or increased staining for MIB-1.
  • No particular clinical variables (BRCA 1 vs. BRCA 2 mutation, parity, personal history of breast cancer, prior abdomino-pelvic surgery, or intraoperative findings) or benign pathologic alterations in the RRSO specimens were associated with the presence of transitional cell metaplasia of the fimbriae.
  • This study demonstrates that transitional cell metaplasia of the fimbriae is a common benign finding in RRSO specimens that should not be confused with the much less common finding of tubal intraepithelial carcinoma.

  • [Title] Ovarian nonsmall cell neuroendocrine carcinoma: a clinicopathologic and immunohistochemical study of 11 cases.
  • Nonsmall cell neuroendocrine carcinoma (NSCNEC) of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms.
  • Tumors were mostly unilateral, cystic, or solid/cystic and ranged in size from 5 to 26 cm (mean 16.2).
  • In 8 cases, NSCNEC was associated with other epithelial neoplasms, including mucinous neoplasms of low malignant potential, mucinous carcinoma, endometrioid carcinoma, mixed endometrioid and mucinous carcinoma, and a high-grade carcinoma, not otherwise specified.
  • In 2 cases, the tumor was associated with a mature cystic teratoma; one of them also containing an invasive moderately differentiated adenocarcinoma.
  • A single case was associated with a benign ovarian cyst.
  • The latter case had a dermoid cyst in the contralateral ovary.
  • NSCNEC represented anywhere from 10% to 90% of the ovarian tumor.
  • All tumors had a brisk mitotic activity.
  • According to the International Federation of Gynecology and Obstetrics staging system, 4 cases were stage I tumors, 3 cases were stage III tumors, and 4 cases were stage IV tumors.
  • Four of 5 patients who died of disease had either stage III or IV tumors and 3 of 5 patients who are alive without evidence of disease have stage I tumors.
  • In summary, ovarian NSCNEC is an aggressive tumor with a tendency to present at advanced stage and cause death within a mean of 17 months after diagnosis; however, some patients, particularly those with stage I disease and/or those who have received platinum-based therapy, may have a more favorable prognosis.

  • The biologic behaviour of teratomas depends on various interdependent clinical and epidemiologic variables such as the age at diagnosis, sex, tumor site, histology which all correlate to different cytogenetic and molecular biologic aberrations.
  • Thus, testicular teratomas of infancy are generally benign.
  • In contrast, postpubertal testicular teratomas can present as clinically malignant tumors and may show complex cytogenetic aberrations such as the isochromosome 12p, which is pathognomonic of malignant germ cell tumors.
  • Notably, teratomas of both age groups show an at least partial erasure of the genomic imprinting, correlating with their origin from primordial germ cells.
  • The Kiel Pediatric Tumor Registry includes 541 teratoma specimens, and among these, the most frequent tumor sites (in descending order) are: the sacrococcygeal region (33.8 %), the ovaries (31.2 %) and the testes (10.5 %).
  • The WHO classification of germ cell tumors distinguishes mature and immature teratomas as well as teratomas with malignant transformation.
  • The frequency of additional microscopic foci of malignant yolk sac tumor correlates with the grade of immaturity.
  • In sacrococcygeal teratomas, the yolk sac tumor microfoci may give rise to a malignant relapse after incomplete resection.
  • Here, molecular genetic analysis has demonstrated the origin of the somatic malignancy from a malignant transformation within the germ cell tumor with retention of the cytogenetic changes characteristic of malignant germ cell tumors.

  • [Title] Can we preoperatively risk stratify ovarian masses for malignancy?
  • PURPOSE: Given a 10% malignancy rate in pediatric ovarian masses, what preoperative factors are helpful in distinguishing those at higher risk to risk stratify accordingly?
  • METHODS: After institutional review board approval (IRB#022008-095), a 15(1/2)-year retrospective review of operative ovarian cases was performed.
  • RESULTS: A total of 424 patients were identified, with a mean age 12.5 years (range, 1 day to 19 years), without an age disparity between benign (12.54 years, 89%) and malignant (11.8 years, 11%) cases.
  • Imaging of benign neoplasms had a mean size of 8 cm (range, 0.9-36 cm) compared with malignancies at 17.3 cm (6.2-50 cm, P < .001).
  • An ovarian mass size of 8 cm or longer on preoperative imaging had an OR of 19.0 for malignancy (95% CI, 4.42-81.69).
  • The malignancies (n = 46) included germ cell (50%, n = 23), stromal (28%, n = 13), epithelial (17%, n = 8), and other (4%, n = 2).
  • Tumor markers obtained in 71% of malignancies were elevated in only 54%, whereas 6.5% of those sent in benign cases were similarly elevated.
  • CONCLUSION: This reported series of pediatric ovarian masses demonstrates that preoperative indicators that best predict an ovarian malignancy are a complaint of a mass or precocious puberty, a mass exceeding 8 cm or a mass with solid imaging characteristics.
  • Tumor markers, positive or negative, were not conclusive in all cases but useful for postoperative surveillance.

  • [Title] [The role of selected molecular pathways in the pathogenesis of ovarian teratomas].
  • From the research point of view--ovarian teratomas, especially mature ones, are an interesting group of germ-cell tumors of the ovary.
  • The WHO classification, which is not simple but includes all tumors that arise from germ cells, emphasizes the complexity of this group.
  • Mature ovarian teratomas are benign germ-cell tumors, but in rare cases, especially when they contain solid elements, peritoneal implants may be present which can stimulate malignant processes.
  • Dermoid cysts, a subtype of ovarian teratomas, arise from totipotential germ cells and may therefore contain elements of all three germ layers, although ectodermal structures usually predominate.
  • Radical surgical treatment is not necessity for this type of tumor because conservative surgery usually brings full recovery.However, they make perfect material for gaining interesting information regarding oocyte maturation and such critical cellular functions as proliferation, migration, differentiation, and apoptosis.There are still no unequivocal conclusions related to the role of mutation in genes which influence the mechanisms involved in control of the cell cycle and which may play important roles in the development of ovarian teratomas.
  • In this review the roles of the Patched/Hedgehog and PI3K/Akt pathways and cyclin D protein in the neoplastic transformations of the germ cells are described.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Premenarchal ovarian torsion and elevated CA-125.
  • BACKGROUND: Ovarian tumors are the most common gynecologic malignancy occurring in childhood, with germ cell tumors being most frequent.
  • This contrasts with adults where epithelial tumors account for most ovarian neoplasms.
  • Tumor markers are an integral part of the work-up and may guide management.
  • Other tumor markers were normal.
  • Laparoscopy revealed an enlarged, adherent ovary.
  • A minilaparotomy revealed an ovary filled with necrotic material.
  • This necrotic material was excised and the ovary was spared.
  • SUMMARY AND CONCLUSIONS: This case demonstrates for the first time the association of an elevated CA-125 and ovarian torsion in a pediatric patient.
  • This benign finding allowed attempting a conservative ovary-sparing approach during the surgery even in the presence of a highly elevated CA-125.
  • However, in general, for children CA-125 is of limited utility, as it will not affect the indication for surgical exploration of persistent masses and elevations in CA-125 may discourage ovarian conservation.

  • [Title] Virilizing ovarian dermoid cyst with leydig cells.
  • Overall, ovarian tumors causing virilization are exceedingly rare and mostly occur in post-menopausal women.
  • In fact, there are no reported cases of virilization from a testosterone-producing ovarian dermoid in the adolescent female age group.
  • The most frequent germ cell tumor derived from the ovaries is the benign cystic teratoma (dermoid) which accounts for 25% of all ovarian neoplasms.
  • Usually the tumors are asymptomatic, but they occasionally can cause severe pain if there is torsion or if sebaceous material perforates the cyst wall, leading to reactive peritonitis.
  • CASE: A 12-year-old female was found to have a large 3 5 x 19 x 12 cm ovarian mature cystic teratoma arising from her right ovary.
  • CONCLUSION: Benign cystic teratomas can produce active hormones, albeit rarely.
  • This is a finding important to consider when ovarian cystectomy is performed for removal of a benign cystic teratoma.
