Primary peripheral adenoid cystic carcinoma of the lung and literature comparison of features

Abstract

Adenoid cystic carcinoma arising from the peripheral lung is rare. Here, we describe adenoid cystic carcinoma that developed in the peripherally in S9 of the right lower lobe of an 84 year-old woman. Cell blocks prepared from the bronchial wash specimens exhibited the cribriform formation. An immunohistochemical examination of the surgically resected tumor revealed positive thyroid transcription factor-I and c-kit stain- ing. Exons 9 and 11 of c-kit in tumor cells were not mutated. We compared the clinical features of this patient with those of 10 others described in the English-language literature. © 2007 The Japanese Society of Internal Medicine.
