title: [Baso- and spinocellular Pinkus fibroepithelial tumor].
abstract: A seventy-eight-year-old man presented with a moist proliferating tumor of the back which arose six months earlier amidst numerous verrucae seborrheic. The tumor's size was 20 X 28 mm. Two different aspects were found upon histologic examination. One was a Pinkus fibroepithelial tumor with foci of basal cell proliferation, stromal changes with fibrosis, and lymphocytic infiltration. Adjacent to this tumor was a squamous-cell carcinoma. Foci of squamous-cell carcinoma were also found within the Pinkus epithelial tumor.
