BASALOID FOLLICULAR HAMARTOMA
By Gary M. White, MD
Basaloid follicular hamartoma (BFH) is a rare and indolent adnexal tumor with histologic similarity to basal cell carcinoma.
- A solitary and non-inherited type of BFH may present as a flesh-colored papule in an adult. Eighty-seven percent occur on the face or scalp.
- Familial BFH may present as 1-2 mm diameter skin-colored or hyperpigmented papules on the face, scalp, and trunk. Often, small milia-like and comedone-like papules are also present.
- There is overlap histologically with basaloid follicular hamartomas (BFH) and indeed some reported cases of familial BFH may represent the same entity.
As noted above, in the solitary case, a flesh-colored papule is seen, usually on the face or scalp. In familial BFH, multiple flesh-colored papules occur on the face, scalp and trunk.
Simple excision or destruction is appropriate for solitary lesions.
