[Solitary intrapulmonary fibrous tumor with an adenofibromatous pattern: A case report]

Solitary fibrous tumor is a neoplasm of mesenchymal origin that generally occurs in the pleura and is usually benign. An intrapulmonary location is rare and the adenofibromatous pattern is even more infrequent. We present a case of a solitary intrapulmonary fibrous tumor with adenofibromatous characteristics in a patient with a history of adenocarcinoma of the prostate. Immunohistochemically, the tumor was positive for STAT6, CD34 and Bcl-2.
