  • [Title] Malignant transformation of a medulloepithelioma of the optic nerve.
  • OBJECTIVE: To describe a case of malignant transformation of a medulloepithelioma of the optic nerve.
  • A benign non-teratoid medulloepithelioma of the optic nerve was surgically removed.
  • The boy was further treated with chemotherapy and radiotherapy and is still alive 36 months after primary surgery.
  • RESULTS: Medulloepithelioma of the optic nerve is extremely rare.
  • This is the first case described of a benign medulloepithelioma of the optic nerve, later transforming into a malignant tumour.
  • One third of patients with medulloepithelioma of the optic nerve have died from direct intracranial spread or metastasis to the central nervous system (CNS).
  • CONCLUSIONS: Medulloepithelioma of the optic nerve should be considered malignant despite morphology with tendency to spread to the CNS.
  • Furthermore; it should be considered as a differential diagnosis when observing a tumour of the optic nerve in a child.

  • [Title] Malignant astrocytoma arising 10 years after combined treatment of craniopharyngioma.
  • After surgery he underwent conventional radiation therapy with a total tumor dose of 55 Gy, and had hormonal support with DDAVP, thyroxine, and a variable dose of hydrocortisone.
  • Growth velocity declined slowly in the first 4 years, but improved later on again without GH therapy despite abnormal provocative tests.
  • At the age of 15 years he developed peripheral facial nerve palsy due to a malignant astrocytoma (WHO grade III/IV).
  • Repeated conventional radiation therapy with an additional stereotactic boost and chemotherapy could not prevent the fatal outcome.
  • This observation may temper the use of radiosurgery in benign intracranial tumors.

  • [Title] Malignant peripheral nerve sheath tumours--report of 8 cases and review of the literature.
  • BACKGROUND: Though Malignant peripheral nerve sheath tumours (MPNST) are a rare entity accounting for 5-10% of soft-tissue sarcomas they are an important differential diagnosis to benign tumours of the peripheral nervous system regarding treatment and prognosis.
  • Two patients suffered from Neurofibromatosis type 1.
  • All of these developed local recurrence with a mean disease free survival time of 10.6 months.
  • During follow up, three patients developed distant metastases located in the lung, liver and subcutaneous tissue.
  • Five out of eight patients died during follow-up with a mean survival time of 11.6 months after diagnosis.
  • Though mulitimodal therapy including surgical resection and adjuvant radiotherapy including brachytherapy is available, the prognosis remains dismal.
  • Modern clinical studies and the development of effective chemotherapy is needed in order to gain control of the disease.

  • Benign tumours account for 80% of case histories with a relationship 1:4 M/F, the most frequent being pleomorphic adenoma (57.3% of cases), followed by Warthin's tumour (32.4%), this rating not having been confirmed in case histories (8-10%) in the literature.
  • Diagnostic work-up included echotomography and fine-needle aspiration biopsy, less used imaging techniques were computed tomography, magnetic resonance imaging, Sialo-computed tomography.
  • Surgical treatment of benign tumours consisted, in 50% of cases, in superficial paroditectomy and in approximately 30% of total paroditectomy.
  • For malignant neoplasms, total parotidectomy was performed in approximately 50% of cases, while in the remaining 50% an almost equal rate of superficial parotidectomy was carried out and enlarged parotidectomy, with or without sacrificing the facial nerve, which was rebuilt in 60% of cases.
  • The lateral neck dissection most frequently carried out was of functional type in 54% and selective type in 46% with removal of levels I-III and II-IV in approximately 60% of cases.
  • Post-operative-complementary radiotherapy was very frequently performed instead of chemotherapy.
  • Oncological results obtained were compared with those reported in the literature: in fact for all benign neoplasms relapse ratings are about 5%, while for malignant tumours the worst prognosis was in squamous cell carcinoma with median of 37.7 on survival and metastasis rate of 16.5%.

  • [Title] [Parathyroid carcinoma. Therapeutic strategies derived from 20 years of experience].
  • We describe their clinical presentation, treatment and results obtained.
  • The symptoms at onset included: nephrolithiasis in 10 cases, osteoporosis in 4 (3 of which presented uremic syndromes), gastrointestinal symptoms (gastritis) in 1 case, a palpable cervical mass in 1 patient and recurrent nerve palsy in one case suffering from familial IPT.
  • RESULTS: Parathyroid carcinoma was correctly diagnosed during the first operation in 14 cases (this diagnosis was suspected in 10 cases following intraoperative frozen session), whereas the first diagnosis was of benign disease in 3 patients.
  • Two patients underwent radiotherapy after surgery and one received chemotherapy.
  • CONCLUSIONS: In conclusion, high blood levels of calcium and PTH, a palpable mass at the neck, with recurrent nerve paralysis, aspects of local invasiveness should alert the surgeon and guide him towards surgery that includes resection of the parathyroid en bloc with the adjacent structures, although there is no proof that a more extensive surgery is correlated with a more favourable prognosis.

  • [Title] EGFR-dependent and independent activation of Akt/mTOR cascade in bone and soft tissue tumors.
  • To gain the insight into the involvement of signaling mediated by the mammalian target of rapamycin (mTOR) in the phenotype and biological profiles of tumors and tumor-like lesions of the bone and soft tissue, we analyzed the expression and phosphorylation (activation) of mTOR and its correlation with the status of upstream and downstream modulator proteins Akt, p70S6-kinase (S6K), and eukaryotic initiation factor 4E-binding protein 1 (4E-BP1), which we refer to collectively as mTOR cassette proteins.
  • Immunohistochemical analysis of 140 cases showed activation of Akt in 55% (61% in malignant and 27% in benign), and mTOR expression in 61% (66% in malignant and 39% in benign).
  • The preponderance of mTOR activation was found in tumors of peripheral nerve sheath (malignant peripheral nerve sheath tumor and schwannoma), skeletal muscle origin (rhabdomyosarcoma), and in those exhibiting epithelial nature (chordoma and synovial sarcoma).
  • We conclude that mTOR-mediated signaling proteins function not only in the proliferation of the tumor cells, but also in the differentiation and/or maintenance of morphological phenotypes in tumors of rhabdomyoblastic and nerve sheath cell origin.
  • Overall, these results suggest that inhibitors of mTOR cassette may be useful as novel components of combined chemotherapy for a defined subset of bone and soft tissue sarcomas.

  • OBJECTIVE: To describe the clinicopathological presentation and treatment options in epithelial parotid tumours with emphasis on surgery.
  • Clinical presentation, preoperative investigations, operative procedure, histopathology report, postoperative complications and further management were recorded.
  • Majority of tumours were benign, only two were recurrent.
  • Parotid pleomorphic Adenoma (PPA) was the commonest benign tumour, others being Warthin's tumour and monomorphic adenoma.
  • Except for one child, rest of the 13 patients received postoperative radiotherapy and one patient of lymphoepithelioma received chemotherapy in addition.
  • CONCLUSION: Benign and malignant epithelial parotid tumours can be diagnosed by their clinical presentation supplemented with FNAC.
  • Facial nerve can be saved in total conservative parotidectomy for benign tumour in deep lobe and early malignant tumour.

  • [Title] Role of endoscopic ultrasound in diagnosis and therapy of pancreatic adenocarcinoma.
  • Since its advent more than 20 years ago, endoscopic ultrasound (EUS) has undergone evolution from an experimental to a diagnostic instrument and is now established as a therapeutic tool for endoscopists.
  • Endoscopic ultrasound cannot accurately distinguish benign from malignant changes in the primary lesion or lymph node on imaging alone.
  • The curved linear array echoendoscope enables the visualization of a needle as it exits from the biopsy channel in the same plane of ultrasound imaging in real time.

  • Pilocytic astrocytoma is the most common pediatric central nervous system glial neoplasm and the most common pediatric cerebellar tumor.
  • This tumor has a noteworthy benign biologic behavior that translates into an extremely high survival rate-94% at 10 years-that is by far the best of any glial tumor.
  • The cerebellum, optic nerve and chiasm, and hypothalamic region are the most common locations, but the tumor can also be found in the cerebral hemisphere, ventricles, and spinal cord.
  • Surgical resection is the treatment of choice for all tumors, except for those involving the optic pathway and hypothalamic region, which may be treated with radiation therapy and chemotherapy.
  • Accurate interpretation of imaging studies plays an essential role in directing treatment of these tumors, particularly when they arise in the optic pathway of patients with neurofibromatosis type 1.

  • [Title] Regional spread of nonneurogenic tumors to the skull base via the facial nerve.
  • OBJECTIVE: This study examined the clinical and pathologic features of regional spread of nonneurogenic neoplastic disease to the intratemporal segments of the facial nerve.
  • PATIENTS: Six patients with neoplastic disease of nonneurogenic origin involving segments of the facial nerve within the temporal bone.
  • Five patients received adjuvant radiation, and two received adjuvant radiation and chemotherapy.
  • MAIN OUTCOME MEASURES: Histopathology, site of primary tumor, intratemporal location of regional spread along the facial nerve, degree of facial paralysis, and presence of residual disease.
  • In addition, one case of benign pleomorphic adenoma of the parotid gland that circumferentially involved an intratemporal segment of the facial nerve was reported.
  • Four patients had unresectable malignant disease, and two died despite multimodality therapy.
  • CONCLUSIONS: The facial nerve provides a route for the spread of neoplastic disease into the temporal bone, and perineural invasion is an important mechanism of invasion and motility of malignant disease.
  • Nonneurogenic intratemporal tumors of the facial nerve are a rare but significant cause of facial paralysis.
