Abstract
Oncocytoma is an uncommon neoplasm with a characteristic histologic feature of abundant eosinophilic granular cytoplasm. It almost always occurs in kidney, thyroid, or salivary gland. Pulmonary oncocytoma is a rare pulmonary neoplasm, with fewer than 10 cases reported so far in the available English literature. We encountered one such case that was successfully managed by thoracoscopic lobectomy.

Summary
Oncocytoma is an uncommon neoplasm of oncocytes (cells of epithelial origin), characterized by abundant eosinophilic granular cytoplasm[1]. Hamper first coined the term “oncocytes” for large, highly eosinophilic granular cells associated with Hürthle cell tumours of the thyroid gland in 19502. Oncocytomas are most commonly found in kidney, thyroid, and salivary gland[3]. Tumours arising in the lung are exceptionally rare, with fewer than 10 cases having been reported to date in the English literature. We present the case of a male patient with a histologically proven pulmonary oncocytoma that was successfully managed by thoracoscopic lobectomy, and we review the literature about this rare clinical entity
