Diagnosis: Frontal fibrosing alopecia (FFA), a variant of lichen planopilaris (LPP).
MICROSCOPIC FINDINGS AND CLINICAL COURSE
Horizontal sections showed a decreased number of terminal anagen follicles and an infiltrate of lymphocytes and eosinophils juxtaposed on remaining infundibula, as well as concentric peri-infundibular fibrosis. There was loss of sebaceous lobules.
The patient was treated with intralesional corticosteroids (triamcinolone acetonide [Kenalog]) with significant reduction of her scalp pruritus and subjective slowing of the progression of hair loss. Clinically, there was reduction in perifollicular erythema and scale; anagen hairs remained easily extractable on a hair-pull test.
DISCUSSION
Frontal fibrosing alopecia, a cicatricial alopecia in a characteristic distribution, was first described by Kossard1 in 1994. Since then, there have been few reports of this entity in the literature.2-6 The clinical hallmark of FFA is the onset of alopecia in a bandlike distribution along, and anterior to, the frontal hairline of an older woman, frequently accompanied by loss of eyebrows. To date, no similar presentation has been reported in men.
