title: Intraosseous glomus tumor in acromion process of scapula.
abstract: A 25-year-old woman presented with a 5-year history of left shoulder pain, which was constant dull aching in nature, non-radiating with no relieving or aggravating factors and no seasonal variation, gradually increasing in intensity over years. There was no history of trauma or constitutional symptoms. the patient had taken anti-tubercular drugs for 6 months for this pain with no relief. There was point tenderness over the left acromion process. Local temperature was not raised. Movements of the left shoulder were not effected. All routine hematological investigations were normal. Surgical exploration of the lesion revealed a normal soft tissue periosteum and cortex. On removing the cortical bone a red colored jellified tissue was isolated and thoroughly curetted. Histopathology revealed intraosseous glomus tumor. The patient became pain free immediately postoperatively and continued to be symptom free at 24-month follow-up. Glomus tumor located within bone is rare. Only 22 cases of primary intraosseous glomus tumor have been reported in world literature. Glomus tumors are generally treated by meticulously shelling out the entire lesion. Recurrence of symptoms and the need for reoperation have been reported between 12% and 24%. Most authors assume the recurrence is due to inadequate excision, prompting some to recommend more extensive en bloc excision. Tuberculosis being endemic in this region, antituberculer chemotherapy is generally started on clinical suspicion and tissue diagnosis is only attempted in nonresponders. This case however re-emphasizes the value of tissue diagnosis especially when a lesion is at an unusual site like the acromion process.
