Fibroepithelioma of pinkus on mucocutaneous junction.
Fibroepithelioma of Pinkus is a variant form of basal cell carcinoma that clinically presents as a single or multiple red plaques or flesh-colored nodules without ulceration. It is usually located in the trunk, inguinal, or crural areas and only rarely occurs on the mucocutaneous junction. A 57-year-old male patient presented with a mass at the left nostril, which had first appeared about 10 years earlier. A single nontender red lesion was about 1 cm in size, and its base was on the mucocutaneous junction at the floor of the left nostril. The patient did not complain of any pain. Computed tomography results revealed a 0.8 × 0.8 × 1.0-cm mass with moderate enhancement at the left nostril without infiltration to the adjacent soft tissue. Wide local excision was carried out with an adequate resection margin under local anesthesia. Microscopic examination showed strands of basaloid cells infiltrating into the stroma, forming an interanastomosing pattern. The specimen exhibited no atypia, and the margin of excised mass was clear. The patient is being monitored for any possible local recurrence.
