OBJECTIVE To report the first operated and histopathologically studied case of spontaneously resolving solitary osteochondroma. CASE PRESENTATION AND IDENTIFICATION An 18-year-old girl presented with leg pain of 2 months' duration. She had been diagnosed to have a proximal tibial osteochondroma since the age of 9 years. Excision biopsy of the tumor remnant and its surrounding tissue was done ...

Osteochondroma is the most common benign tumor of bone, and the majority arise in the appendicular skeleton. Spinal osteochondromas are uncommon, with 50% occurring in the cervical spine. Only 0.5% to 1% of spinal osteochondromas present with neurological dysfunction. Only 12 of such solitary symptomatic osteochondromas have been previously reported in the literature to arise from C2. We report...

constitutes 20-25 % of benign bone tumors (1), and has been estimated to be present in 1-2% of individuals based on extensive skeletal evaluations. The chest radiography findings in our case resembled those of a mediastinal mass lesion. An osteochondroma usually is composed of cortical and medullary bone that is continuous with the parent bony cortex and medullary canals. The clinical significa...

Osteochondroma is the most common benign bone tumor. Approximately 15% of osteochondromas occur as multiple lesions. Multiple osteochondromatosis has a higher risk of developing chondrosarcomas, which are of low grade with good prognosis. About 10% of all chondrosarcomas may undergo dedifferentiated change, which has a poorer prognosis. Dedifferentiated peripheral chondrosarcoma developing with...

We present a 22-year-old man with osteochondromatosis and osteochondroma involving bilateral patella and patellar tendon with restriction of joint movement and severe arthritis.

Extraskeletal osteochondroma in parapharyngeal space is very rare. It is important to note that such a diagnosis be considered when a discrete, ossified mass is localized in soft tissues, even at atypical sites. Its diagnosis is based on radiological and histopathological examination. We should be clinically aware of this benign entity as no malignant transformation or metastasis has been repor...

Osteochondroma is the most common benign bone tumor and usually occurs in the metaphyseal region of the long bones. This tumor takes the form of a cartilage-capped bony outgrowth on the surface of the bone. The vast majority (85%) of osteochondromas present as solitary, nonhereditary lesions. Approximately 15% of osteochondromas occur as multiple lesions in the context of hereditary multiple os...

INTRODUCTION Osteochondroma of the cervical spine is an uncommon bony tumour. CLINICAL PICTURE We present a case which was misdiagnosed as a posterior cervical lymph node. The patient presented with a tender neck lump and was seen by two surgical departments. They eventually diagnosed it as an osteochondroma and referred the patient to our department. This exostosis arose from the lamina of C...
