Background
The fibroepithelioma of Pinkus is an unusual neoplasm that was first described by Hermann Pinkus in 1953 as a premalignant fibroepithelial tumor.
Clinically, the lesion is a benign-appearing, pedunculated, pink tumor that may resemble an acrochordon. However, Pinkus noted 4 such lesions to have a peculiar histologic appearance that resembled both a reticulated seborrheic keratosis and a basal cell carcinoma. Pinkus considered the tumor to be a variant of basal cell carcinoma, which illustrated the interaction and interdependence of stromal and epithelial components of basal cell carcinoma.
