Abstract

|
Fibroepithelioma of Pinkus (FEP) is an uncommon variant of basal cell carcinoma and this typically appears as single or multiple nodular lesions on the lower back of the elderly. We report here on a case of a 59-year-old woman who presented with an asymptomatic erythematous sessile plaque on the lateral side of her right thigh, and she’d had this lesion for 8 years. Histologic examination showed anastomosing strands of basaloid cells extending from the overlying epidermis into the dermis. The tumor cells with large, oval nuclei and relatively little cytoplasms were grouped in a palisade pattern at the periphery of the tumor mass. The tumor was completely excised with a clear resection margin. The patient showed no recurrence for 10 months. For an elderly patient with a long-standing nodule found anywhere on the body, performing a skin biopsy should be considered to exclude malignancy, including FEP.
