Abstract

OBJECTIVE: To report a case of scapular osteochondroma extending from infero - medial border to dorsal surface associated with pain and winging that is rarely reported in the medical literature. CASE PRESENTATION AND IDENTIFICATION: A19-year-old male presented with pain and winging of the left scapula. CT scan revealed an osteochondroma of the medial border of the scapula with extensive growth over the dorsal surface beneath infraspinatus. Excision of the tumour relieved the symptoms. Pathological study showed osteochondroma of the scapula. In a follow-up 1 year later he was free of pain with no clinical or radiological sign of recurrence. CONCLUSION: A case of scapular osteochondroma associated with pain and winging treated by excision and follow-up showed no sign of clinical or radiological recurrence. INTRODUCTION: Osteochondroma is the most common benign tumour of the bones (1, 2). Most of which occurs in long bone at its metaphyseal region. Rarely the tumour occurs in flat bones; its incidence in scapula is less than 4 % (3) . Most of the osteochondroma of the scapula are asymptomatic but carries an inherent risk of malignant transformation as with the osteochondromas of flat bone, and winging of scapula. Here we report a large osteochondroma arising from the medial border of the right scapula in a young adult male with a large sessile extension over the dorsal surface beneath the infrascapular muscle and associated with pain and winging. CASE REPORT: A 17 years old male patient presented to us with the swelling dorsal aspect of left scapular region of 1 year duration with history of progressive increase in size. On examination swelling was oval in horizontal plane, lobulated, 8 x 6 cm, and bony hard consistency, fixed to underlying scapula from the dorso-medial aspect. The movement at the shoulder joint is normal except the winging of left scapula when pushing the upper limb forward against the wall. No bony prominences are found elsewhere in the body. Patient was admitted for surgical excision for the apprehension of malignant transformation of swelling on part of patient and for the cosmetic reasons. Winging of the scapula was not troublesome for the patient.
