A Case of Nodular and Fibroepithelial Type Fibroepithelioma / 대한피부과학회지

ABSTRACT

Fibroepithelioma is a rare subtype of basal cell carcinoma (BCC) with a distinct growth pattern. We report a case of a 68 year-old man who presented with a 1.7x1.0x0.5 cm sized pedunculated mass on his left axilla. Histopathologic examination revealed two distinct patterns at the same time; a large nodular mass with a peripheral palisading pattern and a small locus of strands in a fenestrated fashion. In higher magnification, there were long, thin, branching, and anastomosing epithelial strands embedded in a fibrous stroma. Small buds were seen projecting from the epithelial strands, with many of the strands showing connections to the surface epidermis. The tumor was totally excised, and the patient has shown no evidence of recurrence for 4 months. This case shows an example of atypical fibroepithelioma with two distinct histopathologic types.
