INFUNDIBULOCYSTIC BASAL-CELL CARCINOMA

We report on a 72-year-old male patient with a solitary, dome-shaped t umor on the preauricular region. Histologically, it showed an intrader mal basaloid cell tumor composed of many anastomosing epithelial cords . There were multiple infundibular cystic structures containing corneo cytes Lined by follicular infundibular epithelium and bud-like structu res simulating the follicular germs throughout the neoplasm. Follicula r bulbs and papillae were absent within the tumor. The stroma was scan t and not highly fibroplastic. The tumor was diagnosed as infundibuloc ystic basal cell carcinoma, a recently described, uncommon variant of basal cell carcinoma.
