Abstract

A 43-year-old woman had an incidental lung mass identified on shoulder x-ray performed for pain. Contrast-enhanced CT showed a 38-mm mass in the medial segment of the right middle lobe, with features suggestive of carcinoid tumor. A In-pentetreotide scan showed intense uptake; furthermore, fine needle aspiration biopsy yielded neuroendocrine cells confirming the carcinoid hypothesis. However, definitive surgical histology showed a sclerosing pneumocytoma. This could potentially suggest that such rare tumors, with metastatic potential, could respond to somatostatin analogue treatment.
