  • [Title] Giant solitary osteochondroma of the inferior medial calcaneal tubercle: a case report and review of the literature.
  • Osteochondromas are benign osseous neoplasms with a distinct hyaline cartilage cap originating from the physis and cease growing with skeletal maturity.
  • Osteochondroma are often treated conservatively unless they become symptomatic, painful, demonstrate rapid or new growth, enlarge after skeletal maturity, and/or exhibit signs of malignant transformation.
  • In this report, we present a case of a giant (8 cm x 4.2 cm x 2.1 cm) osteochondroma in an adult occurring on the inferior medial tubercle of the calcaneus that underwent excision, with 3.5 years of follow-up without recurrence.
  • To our knowledge this is the largest osteochondroma affecting the inferior medial tubercle of the calcaneus.
  • This case demonstrates that large osteochondromas may occur in the foot, and also confirms that benign osteochondroma growth may occur in adulthood.
  • A detailed review of osteochondroma occurrence in the foot is presented along with a review of the diagnostic work-up to evaluate for malignant transformation.

  • INTRODUCTION: Chondromas are uncommon benign tumors of cartilaginous origin.
  • Irregular calcifications may be seen with radiolucencies and then it is an osteochondroma.
  • DISCUSSION AND CONCLUSION: Chondromyxoid fibroma (CMF) is a rare, benign cartilaginous tumor that often occurs in the metaphyses of proximal tibia, proximal and distal femur and small bones of the foot.
  • The differential diagnosis is wide and includes simple or aneyrismal bone cyst, giant cell tumor, nonossifying fibroma, fibrous dysplasia, enchondroma, chondroblastoma, eosinophilic granuloma and fibrous cortical defect.
  • In the diagnosis of an intracranial chondrocytic tumor, it is important to distinguish it from enchondroma and chondrosarcoma.
  • MR provides a detailed assessment of soft tissue masses of the craniofacial region, while CT offers superior analysis of bone structure involvement.
  • The present case underlines the importance of MR examination in the diagnosis of soft tissue masses in the craniofacial region.

  • [Title] Calcaneal osteochondroma.
  • Osteochondromas are essentially the most common primary bone tumors.
  • These benign cartilage producing neoplasms are generally asymptomatic and have a relatively small potential for adverse effects.
  • Various imaging techniques can be used to characterize these lesions, but in the absence of symptoms or signs of complications, plain-film radiography is usually sufficient for diagnosis as this tumor has a characteristic radiographic appearance.
  • Once this benign tumor is identified and more serious forms of tumor are ruled out, treatment is generally not needed.

  • [Title] Osteochondroma of the convexity: pathologic-neuroimaging correlates of a lesion that mimics high-grade meningioma.
  • Intracranial chondromas are uncommon benign lesions usually attached to dura and located over the convexity of the skull.
  • Osteochondromas are even rarer and additionally contain a benign bony component.
  • Extensive histological sectioning revealed a benign osteochondroma predominantly composed of lobules of hypocellular cartilage.
  • Microdissection of the different components revealed that the multifocal, spicule-like bright foci interpreted as hemorrhage on neuroimaging studies were instead foci of benign bone containing metaplastic bone marrow with trilineage hematopoietic cell populations and adipose tissue.
  • Rare convexity osteochondromas may be mistaken for high-grade meningiomas on neuroimaging studies; their avascular nature, coupled with their complex signal pattern can serve as clues to the correct pre-operative diagnosis.

  • [Title] A calcaneal osteochondroma with recurrence in a skeletally mature patient: a case report.
  • INTRODUCTION: Osteochondroma is the most common benign tumor of the skeleton.
  • However, calcaneal osteochondroma is very rare.
  • In an adult, growth of an osteochondroma suggests the diagnosis of malignant transformation to a chondrosarcoma.
  • However, enlargement of an osteochondroma reported as benign after skeletal maturity is present in literature.
  • CASE PRESENTATION: We report the clinical and radiologic findings of a calcaneal osteochondroma with an extremely rare placement and painfull, rapid reccurence following surgical excision in a skeletally mature female.
  • CONCLUSION: It should kept in mind that benign osteochondromas can show symptomatic growth in skeletally mature patients without malignant transformation.

  • [Title] Pathological study of bone tumours at the National Orthopaedic Hospital, Lagos, Nigeria.
  • BACKGROUND: Although primary bone tumours are relatively uncommon, they constitute the most important tumours in patients under 20 years.
  • OBJECTIVE: To update the literature on the relative frequency and clinico-pathologic characteristics of bone tumours in this environment.
  • MATERIALS AND METHODS: The clinical and histopathological records of patients presenting with diagnosis of bone tumours between 1999 and 2004 and managed at the National Orthopaedic Hospital, Igbobi, (NOHI) Lagos, Nigeria were review and where necessary, new ones were prepared from the paraffin blocks and stained with routine haematoxylin and eosin stain.
  • RESULTS: Seventy-seven cases were recorded; 61 (79.2%) benign and 16 (15.6%) malignant.
  • The commonest benign bone tumours were osteochondroma and giant cell tumour accounting for 52 (67%) of all cases with > 60% in males.
  • The most common primary malignant bone tumour was osteosarcoma, all in males.
  • Four (5.2%) cases of metastatic bone tumours located commonly in the proximal femur and humerus were also recorded.
  • CONCLUSION: Osteochondroma and giant cell tumours are the commonest benign tumours while osteosarcoma is the most common primary bone tumour all occurring in the first two decades of life.

  • [Title] Horner Syndrome due to a solitary osteochondroma of C7: a case report and review of the literature.
  • OBJECTIVE: To report a 23-year-old woman with osteochondroma of the lower cervical spine who presented with Horner syndrome and to review the relevant literature.
  • SUMMARY OF BACKGROUND DATA: Osteochondroma is the most common benign lesion of bone but rarely affects the spine.
  • No patients with Horner syndrome due to a solitary cervical osteochondroma have been previously reported in English-language medical literature.
  • CONCLUSION: Vertebral involvement of osteochondroma is rare, especially with neurologic compromise.
  • A young patient is presented with a symptomatic solitary osteochondroma of the seventh cervical vertebra who had Horner syndrome.
  • This case report supports surgical intervention of symptomatic osteochondroma of the cervical spine.

  • [Title] Identification of a plasma proteomic signature to distinguish pediatric osteosarcoma from benign osteochondroma.
  • Osteosarcoma (OS) is the most common malignant bone tumor in children.
  • To identify a plasma proteomic signature that can detect OS, we used SELDI MS to perform proteomic profiling on plasma specimens from 29 OS and 20 age-matched osteochondroma (OC) patients.
  • The classifier based on this plasma proteomic signature may be useful to differentiate malignant bone cancer from benign bone tumors and for early detection of OS in high-risk individuals.

  • The diagnosis was malignant tumor in 12 (70%) and benign in 5 (30%).
  • They were Ewing's sarcoma (ES) (n = 4), primitive neuroectodermal tumor (PNET) (n = 3), Askin's tumor (n = 1), rhabdomyosarcoma (RMS) (n = 2), neuroblastoma (n = 2), osteochondroma (n = 1), aneurysmal bone cyst (n = 2) and hamartoma (n = 2).
  • Patients with benign tumor were free of complaints or complications during follow up.
  • Since most of the CWT are malignant and not initially suitable for surgical excision, the management includes tissue diagnosis either by tru-cut or open biopsy.

  • The most important complication is malignant transformation of osteochondroma towards secondary peripheral chondrosarcoma, which is estimated to occur in 0.5-5%.
  • MO is an autosomal dominant disorder and is genetically heterogeneous.
  • The diagnosis is based on radiological and clinical documentation, supplemented with, if available, histological evaluation of osteochondromas.
  • If the exact mutation is known antenatal diagnosis is technically possible.
  • Osteochondromas are benign lesions and do not affect life expectancy.
  • For secondary peripheral chondrosarcoma, en-bloc resection of the lesion and its pseudocapsule with tumour-free margins, preferably in a bone tumour referral centre, should be performed.

  • Although the spectrum of benign and malignant cartilaginous bone tumors is extremely wide, a distinct diagnosis, even from small biopsy specimens, is almost always possible if radiological findings, age, clinical data, and localization within the skeleton as well as within the bone are considered.
  • With limitations, this also holds true for distinguishing enchondromas from low-grade chondrosarcomas; however, extensive experience in multidisciplinary bone tumor diagnosis is required.
  • In single cases, immunohistochemical findings may be helpful in the differential diagnosis if they are integrated into the context of all other findings.

  • Osteochondroma is the most common type of benign bone tumour, and is most often found in the knee region.
  • The lesion is usually clinically silent although it may cause different complications such as fractures of the tumour, bone deformities, neurological disorders, malignant transformation and in rare cases vascular disorders.
  • A delay in diagnosis especially of pseudoaneurysm formation may result in life-threatening situations, extensive operations and lengthy hospital stays.
  • We report the case of a 22-year-old woman with an osteochondroma of the distal femur which caused pseudoaneurysm of the popliteal artery.

  • Skeletal osteochondromas or osteocartilaginous exostoses represent the most common of all benign bone tumors and 10% to 15% of all bone tumors.
  • Osteochondromas are solitary or multiple, pedunculated or sessile exophytic outgrowths from the bone surface that are composed of cortical and medullary bone with an overlying hyaline cartilage cap.
  • Marrow and cortical continuity with the underlying parent bone defines the lesion.
  • In adults, growth or imaging alterations of an osteochondroma suggest the rare diagnosis of malignant transformation; however, extensive growth of osteochondromas without histological evidence of malignancy has been reported

  • AIM: The intent of this report is to present a brief review of the literature on osteochondroma and to present a case involving the surgical removal and replacement of a major portion of the condyle and angle of the mandible using free autogenous mandibular bone.
  • BACKGROUND: While osteochondroma is the most common tumor of skeletal bones, it is relatively uncommon in the jaws occurring at the condyle or the tip of the coronoid process.
  • This benign cartilage-capped growth is usually discovered incidentally on radiographic examination or on palpation of a protruding mass in the affected area.
  • Malocclusion and progressive facial asymmetry are common findings in most cases of condylar osteochondroma.
  • REPORT: A case of a 29-year-old woman with an osteochondroma of the mandibular condyle is presented.
  • As this lesion is usually asymptomatic and discovered incidentally on radiographic examination, the general practitioner usually is the first professional to make the diagnosis.
  • In this case report the extraoral vertical ramus osteotomy, associated with free autogenous mandibular bone, presented several advantages.

  • [Title] Spinal osteochondroma: a report on six patients and a review of the literature.
  • INTRODUCTION: Osteochondromas are the most common benign tumour of the bone.
  • In the diagnosis of osteochondromas, radiological methods are very important.
  • PURPOSE OF STUDY: Because spinal osteochondroma is very rare, other benign and malign tumours should be kept in mind during differential diagnosis.
  • PATIENTS: Between 1986 and 2009, six patients, four males, two females with an average age of 31.2 (9-65) were diagnosed with spinal osteochondroma at our clinic.
  • Because neurological symptoms are rarely seen, radiological examination is of great importance in diagnosis.
  • CONCLUSIONS: Patients suffering from spinal osteochondroma, due to the risk of secondary chondrosarcoma, must be closely evaluated both clinically and radiologically.
  • If necessary, the patient must be treated surgically following histopathological diagnosis.

  • [Title] Immunohistochemical analysis of MDM2 and CDK4 distinguishes low-grade osteosarcoma from benign mimics.
  • Low-grade osteosarcoma is often confused with benign lesions, and ancillary techniques to enhance diagnostic accuracy have been awaited.
  • This study explores the use of MDM2 and CDK4 immunohistochemistry for the histological diagnosis of low-grade osteosarcoma.
  • We studied 23 cases of low-grade osteosarcoma from 21 patients (parosteal osteosarcoma (n=14), low-grade central osteosarcoma (n=9)) and 40 cases of benign histological mimics (myositis ossificans (n=11), fibrous dysplasia (n=14), osteochondroma (n=6), desmoplastic fibroma (n=1), florid reactive periostitis (n=4), Nora's lesion (n=3), and turret exostosis (n=1)).
  • In contrast, only 1 Nora's lesion out of the 40 miscellaneous benign processes showed immunoreactivity for MDM2 or CDK4.
  • The combination of these two markers thus shows 100% sensitivity and 97.5% specificity for the diagnosis of low-grade osteosarcoma.
  • MDM2 and CDK4 immunostains therefore reliably distinguish low-grade osteosarcoma from benign histological mimics, and their combination may serve as a useful adjunct in this difficult differential diagnosis.

  • Osteochondromas are one of the most common benign bone tumors.
  • To date, no reports have described avulsed rupture of the distal biceps tendon caused by an osteochondroma of the bicipital tuberosity.
  • This article presents a case of avulsion of the distal biceps tendon secondary to sessile osteochondroma of the bicipital tuberosity in a 65-year-old right-handed sedentary worker who presented with insidious pain and limited motion in his left elbow for 2 months.
  • The pathologic diagnosis of osteochondroma was confirmed microscopically.
  • We suggest that osteochondroma of the bicipital tuberosity be considered as a cause of painful limitation of forearm rotation or avulsed rupture of the distal biceps tendon.

  • [Title] Improved differentiation of benign osteochondromas from secondary chondrosarcomas with standardized measurement of cartilage cap at CT and MR imaging.
  • PURPOSE: To validate a technique for reproducible measurement of the osteochondroma cartilage cap with computed tomography (CT) and magnetic resonance (MR) imaging and to reevaluate the correlation of the thickness of the cartilage cap with pathologic findings to improve noninvasive differentiation of benign osteochondromas from secondary chondrosarcomas.
  • Patient demographic data, histologic diagnosis, and chondrosarcoma grade were recorded.
  • RESULTS: Evaluated were 67 benign osteochondromas (from 49 male patients and 18 female patients; mean age, 23.4 years) and 34 secondary chondrosarcomas (from 27 male patients and seven female patients; mean age, 33.2 years).
  • With 2 cm used as a cutoff for distinguishing benign osteochondromas from chondrosarcomas, the sensitivities and specificities were 100% and 98% for MR imaging and 100% and 95% for CT, respectively.

  • Hemangioma is the most common benign tumor of the spine.
  • Other primary osseous lesions of the spine are more unusual but may exhibit characteristic imaging features that can help the radiologist develop a differential diagnosis.
  • Because of the complex anatomy of the vertebrae, CT is more useful than conventional radiography for evaluating lesion location and analyzing bone destruction and condensation.
  • The diagnosis of spinal tumors is based on patient age, topographic features of the tumor, and lesion pattern as seen at CT and MR imaging.
  • A systematic approach is useful for recognizing tumors of the spine with characteristic features such as bone island, osteoid osteoma, osteochondroma, chondrosarcoma, vertebral angioma, and aneurysmal bone cyst.
  • In the remaining cases, the differential diagnosis may include other primary spinal tumors, vertebral metastases and major nontumoral lesions simulating a vertebral tumor, Paget disease, spondylitis, echinococcal infection, and aseptic osteitis.

  • [Title] Solitary lower lumbar osteochondroma (spinous process of L3 involvement): a case report.
  • Solitary osteochondromas, which are the most common benign bone tumors of long bones, are rarely found in the vertebral column.
  • The tumor was excised en bloc through a posterior approach and histopathological examination verified the diagnosis of osteocondroma.Osteochondromas are rarely found in the spine, when present in the spine, however, have a predilection for cervical or upper thoracic region arising usually from lamina of vertebrae and are rare in lumbosacral region and very rare at spinous process of the vertebrae.We present a case of osteochondroma locates in lumbar region and spinous process of vertebrae with unusual presentation and was considered clinically as congenital lumbar kyphosis.

  • OBJECTIVE: Review of the cases in a period of 10 years with bone and soft tumors in foot and ankle, to knowing epidemilogical, clinic and patologic anatomy parameters to describe the behavior.
  • RESULTS: 166 patients within 2 years to 78 years old, 81 with bone tumors and 79 with soft tumors, mostly benign, the most frequent was in the soft tissue ganglion and oseal benign exostosis in bone, 6 different malignant tumors, the principal affected zone were the toes, as a difference to literature, the most affected age group was 10 to 20 years followed to the 30 to 40 years old, we report 42 different patological diagnostics results to soft tissue and osseous tissue.
  • CONCLUSION: clinical features is not a useful parameter to differentiate between malign or benign tumors and does not allow to establish the biological behavior, we propose the diagnostic algorithm that includes the intentional clinical probe, comparative X-ray in three projections with soft technique, in suspicion to malignant lesion may require CT scan, MRI, osseous scan and finally biopsy which will improve the final outcome.

  • BPOP is a benign but locally aggressive fibro-osseous mass that has striking clinical, radiographic, and histologic similarities with osteochondroma.
  • Differentiating between the two lesions is important as BPOP often requires more extensive surgical resection and has a higher recurrence rate compared to osteochondroma.
  • This report presents two cases of BPOP where initial clinical diagnosis of osteochondroma was made even after appropriate imaging and histologic samples were evaluated.

  • [Title] Incidence of biopsy-proven bone tumors in children: a report based on the Dutch pathology registration "PALGA".
  • INTRODUCTION: Data on childhood bone tumors are mainly confined to reports on malignant tumors or on institutional registries.
  • Incidence figures on both benign and malignant bone tumors in childhood are lacking.
  • METHODS: From January 1999 to December 2003, 1474 newly diagnosed bone tumors in children up to 18 years were registered in Pathologisch Anatomisch Landelijk Geautomatiseerd Archief (the nationwide network and registry of histopathology and cytopathology in The Netherlands).
  • Data provided were diagnosis, date of birth, age at diagnosis, and localization.
  • RESULTS/CONCLUSIONS: Incidence of pathology-proven bone tumors in children is low.
  • Incidence of pathology-proven bone tumors in The Netherlands is 79.3 per 1,000,000.
  • Osteochondromas are the most prevalent tumors, followed by aneurysmal bone cysts.
  • The overall incidence is higher for male compared with female patients, mainly due to different frequencies found in aneurysmal bone cysts, Ewing sarcoma, and osteochondroma.
  • In infants, bone tumors are mainly chondromas and fibrous dysplasia, which both show a steady increase at older ages.
  • A peak incidence at approximately the age of 10 is noted for solitary bone cysts, nonossifying fibromas, and osteoblastomas.

  • [Title] Secondary chondrosarcoma in cartilage bone tumors: report of 32 patients.
  • BACKGROUND: Secondary malignancies arising from benign bone tumors are rare.
  • Their recognition and diagnosis are difficult, and their slow growth and late recurrence require long-term follow-up.
  • In this study, malignant transformation rates of various histological types of benign cartilage-forming bone tumors in large series were evaluated.
  • METHODS: Between 1986 and 2004, a retrospective analysis of 627 cartilage-forming benign bone tumors revealed that 32 patients had malignant transformation.
  • The patient with Ollier's disease had two chondrosarcomas, and one patient with multiple osteochondroma had three chondrosarcomas.
  • The average time between the initial diagnosis and malignant transformation was 9.8 years.
  • CONCLUSIONS: Cartilage-forming benign bone tumors are rather prone to undergo malignant transformation.
  • Although malignant transformation of a benign bone tumor is a rarely encountered situation, orthopedic surgeons should be cautious while following patients with a benign bone neoplasm.

  • This diagnosis should be considered with the demonstration of a well-circumscribed extraskeletal mineralized mass without any direct continuity with adjacent bone or joint.
  • However, as with other lesions, clinicoradiographic features with histological correlation clinch the diagnosis.
  • We present here such an infrapatellar lesion and discuss criteria helpful in distinguishing these benign lesions from other morphological similar lesions.

  • [Title] Spectrum of bone tumors in Chiang Mai University Hospital, Thailand according to WHO classification 2002: A study of 1,001 cases.
  • OBJECTIVE: The aim of the present study was to determine the spectrum, frequency and demographics of bone tumors.
  • MATERIAL AND METHOD: A retrospective study of the 1,001 bone tumor specimens from the files at the Pathology Department of the Chiang Mai University Hospital, Thailand from 2000 to 2004.
  • The most common benign bone tumors were giant cell tumor (n = 37), osteochondroma (n = 25), and chondroma (n = 15).
  • The most common malignant bone tumors were lymphoma-leukemia (n = 583), metastatic malignancy (n = 104), plasma cell myeloma (n = 71), and osteosarcoma (n = 58).
  • CONCLUSION: The present study showed a higher frequency of osteosarcoma (68%), lower frequencies of chondrosarcoma (12%) and Ewing sarcoma (4%) among primary non-hematologic malignant bone tumors when compared with similar studies based on Western patients.

  • [Title] What's your diagnosis? Osteochondroma with large bursa clinically mimicking malignant transformation.
  • Osteochondroma is a common benign entity.
  • Bursa formation about an osteochondroma may clinically and symptomatically mimic malignant degeneration.
  • Magnetic resonance imaging usually permits unequivocal diagnosis distinguishing between secondary bursitis and malignant degeneration.
  • Magnetic resonance imaging also can differentiate other less common benign complications such as pseudoaneurysm formation caused by the exostosis and fracture at the base of the exostosis.

  • [Title] Surgical management of 121 benign proximal fibula tumors.
  • BACKGROUND: Tumors of the fibula comprise only 2.5% of primary bone lesions.
  • Patients with aggressive benign tumors in the proximal fibula may require en bloc resection.
  • QUESTIONS/PURPOSES: We therefore analyzed the incidence of peroneal nerve palsy, knee stability, and local recurrence following surgical treatment of benign proximal fibula tumors.
  • METHODS: We retrospectively reviewed the charts of 120 patients (121 tumors) with histologically confirmed aggressive benign tumors of the proximal fibula.
  • The most common diagnosis was osteochondroma (38%) followed by giant cell tumor (19%).
