Basaloid follicular hamartoma.

Basaloid follicular hamartoma (BFH) is a unique benign follicular hamartoma characterized by variable clinical presentations, identical histologic features and possible associations with numerous disorders. Basaloid follicular hamartoma may be hereditary or acquired. Hereditary cases may be either generalized or unilateral nevoid. Although the generalized forms are usually associated with systemic manifestations, such as myasthenia gravis,(2) it may occasionally present without internal disorders. On the other hand, the acquired forms of BFH may present in the form of localized or solitary forms. Herein we present four cases of BFH, one of them (first case) represents a unique form of the generalized variant of BFH, showing no associated internal disorders.
