Periosteal chondroma is a relatively rare benign cartilaginous neoplasm usually seen in young adults. We presented three cases of periosteal chondroma in the proximal tibia of a 7-year-old girl (Case 1), a 12-year-old boy (Case 2) and a 15-year-8-month old boy (Case 3). Meticulous analysis of initial and follow-up plain radiographs, Computed Tomography (CT) and Magnetic resonance imaging (MRI) ...

Extraskeletal chondroma can occur in the hands, feet, head and neck. This tumor usually presents as a small solitary nodule. The histogenesis of the tumor is controversial, but some have suggested a metaplastic origin. Chondroma of the fallopian tube is very rare. There is only one report in English literature. The origin of this tumor can be subcoelomic mesenchyme of the tubal serosa or mesenc...

chondromas are benign tumors that may be found in many parts of the body. among intracranial neoplasms, tumors of cartilaginous origin are rare. it has been shown that most of these tumors arise from the skull base. their occurrence in other parts of the intracranial cavity is unusual. chondroma of falx is a rare neoplasm. in this report we introduce a case of falcine chondroma arose from front...

Periosteal chondroma is a rare benign hyaline cartilage neoplasm that occurs most commonly in the metaphases of long tubular bones. We present a unique case of periosteal chondroma arising in the proximal phalanx of the left index finger in a 12-year-old boy. Physical examination revealed a slightly protuberant, subcutaneous mass. Plain radiographs and computed tomography scans showed a periost...

Although tumors or pseudotumoral lesions are rare in the infrapatellar fat, they may affect it. Osteochondroma is the commonest benign bone tumor. However, extraskeletal presentations are rare. There are three extraskeletal variants of osteochondroma: synovial chondromatosis, para-articular chondroma and soft-tissue chondroma. We present a case of a single intra-articular lesion in the area of ...

Chondromas are benign cartilaginous tumours that are uncommon in the head and neck region. Only few cases of chondroma have been reported in the trachea. We present a 70-year-old patient who presented clinically with severe dyspnoea requiring urgent tracheotomy. An oval, expansive, well-delineated tracheal tumour was evident on magnetic resonance imaging. The mass was removed surgically in its ...
