The MRI depicted a small, sharp exostosis tip of the dorsal distal femur with a surrounding soft-tissue mass. After profuse bleeding occurred during biopsy of the soft tissue mass, angiography revealed a pseudoaneurysm of the right popliteal artery. [ncbi.nlm.nih.gov]

[…] may go on to form a fluid filled bursa; - bursal fluid may be mistaken for a soft tissue mass; - Diagnostic studies: - x-ray appearance of an exostosis is either flat, sessile lesion or a peduculated (stalk like) process; - peduncultaed osteochondromas [wheelessonline.com]

In addition, it also causes intrathoracic and extrathoracic soft tissue masses. [jotr.in]

A 72-year-old woman sustained a ureteric avulsion following circulatory collapse at home. Urosonographic imaging revealed hydronephrosis at the left kidney, and abdominal emergency computed tomography showed some fluid around it. [ncbi.nlm.nih.gov]

The thinned shell of bone collapses or is made to collapse using a thin elevator. The posterior canal skin is left intact over the thinned out shell of bone. [drtbalu.co.in]

We hypothesize that severe crushing force anteriorly and laterally caused collapse of the calcaneal body to the middle, also fracturing the inferior cortex and taking a large bony fragment plantarly which developed into large bony exostosis. [faoj.org]

Here, we report the case of a 35-year-old male patient complaining of intermittent claudication over the previous 4 months, without history of trauma or hereditary multiple exostoses. Clinical examination found no popliteal or distal pulses. [ncbi.nlm.nih.gov]

An 18-year-old male presented with a protruding papule on the right great toenail. Diagnosis of subungual exostosis had been established and complete excision was performed. [ncbi.nlm.nih.gov]

Among the dermoscopic features, vascular ectasia was the most common finding (70%), followed by hyperkeratosis (60%), onycholysis (40%), and ulceration (30%). [ncbi.nlm.nih.gov]

A shave biopsy was obtained of the visible portion of the lesion, which revealed hyperkeratosis, acanthosis, and a population of dermal spindle cells in a myxoid stroma that could not be definitively identified. Special stains were nondiagnostic. [mdedge.com]

Ischiofemoral impingement is a rare cause of hip pain related to narrowing of the space between the ischial tuberosity and the lesser trochanter. It is usually seen in middle-aged women. [ncbi.nlm.nih.gov]

Mandibular coronoid process osteochondromas can lead to formation of a pseudo joint and ankylosis. This causes limitation in mouth opening (14). Claudication pain can arise when osteochondromas cause compression of the popliteal artery (15). [jscimedcentral.com]

An 11-year-old boy with known MHE presented 7 months after onset of left elbow pain and loss of flexion-extension to 40 to 120 . Radiographs showed a distal ulna osteochondroma, ulnar shortening, bowing, and radial head dislocation. [ncbi.nlm.nih.gov]

The patient had history of severe osteoporosis with multiple fractures and was on teriparatide for 16 months. On examination, the right thumb was swollen and tender with no superficial erythema or signs of an infection. [ncbi.nlm.nih.gov]
