A Rare Case of Scapulothoracic Bursitis of the Chest Wall with Numerous Rice Grain like Loose Bodies- A Pathological Correlation

Abstract

Scapulothoracic bursitis is a rare disease which is caused from the inflammation of the bursa secondary to trauma or its overuse, owing to sports activities or work. It usually presents with pain, swelling without redness at the scapulothoracic interface. A 22-year-old male presented to the surgeon with the swelling in the left scapular region following a history of trauma. Ultrasound (USG) showed a large loculated fluid collection with internal debris outside the muscular plane. With the clinical diagnosis of haematoma surgical resection was done. It showed a cystic swelling containing haemorrhagic fluid attached to the chest wall. The specimen was sent for histopathological correlation. The thickened cystic structure had numerous rice grain like loose bodies on the inner surface. Microscopy showed fibrocollageneous wall with congested blood vessels, granulation tissue, fibrinoid bodies and macrophages. This case report describes a cystic lesion in left scapular region diagnosed as a case of scapulothoracic bursitis based on pathological correlation. Surgery was an effective treatment for this case with no complication and recurrence on follow-up.
