Familial basaloid follicular hamartoma: a report of one family.

Basaloid follicular hamartoma is a rare but benign adnexal neoplasm that can simulate basal cell carcinoma. Both sporadic and familial variants have been described. We illustrate a family cluster of this unusual entity which presented as milia-like or hyperpigmented papules. Criteria for distinction between the hamartoma and carcinoma are delineated, although evolution of basaloid follicular hamartoma into basal cell carcinoma may also be a possibility.
