Benign endobronchial polyps are rare findings that present a diagnostic dilemma not only for the clinician but also for the pathologist. We describe a man with repeated visits to emergency departments for coughing spells who ultimately underwent bronchoscopy and biopsy. The biopsy specimen was initially diagnosed as a leiomyoma, but the final pathologic diagnosis of the gross specimen was a benign fibroepithelial polyp. We present the clinical history of this patient along with a brief review of the published literature regarding this rare clinical entity.
Rapidly variable findings on chest radiography performed at one institution (A) and then another institution (B) over a 24-hour period. The patient visited separate emergency departments with severe coughing spells.
Hematoxylin-eosin staining of the biopsy specimen. After sending the specimen to an outside institution, a diagnosis of leiomyoma was determined owing to the smooth muscle elements seen here in addition to results with various special stains (original magnification × 400).
Gross anatomical specimen. The dimensions of the polyp were 2.9 × 1.3 × 1.0 cm, and the final diagnosis was a benign fibroepithelial polyp.
