Frontal fibrosing alopecia in a 46-year-old man

Frontal fibrosing alopecia is a scarring alopecia that is characterized by recession of the frontotemporal hairline with the frequent loss of eyebrows. It predominantly affects postmenopausal women and only rarely affects men. We report the case of a 46-year-old man with a ten-year history of an erythematous patch with perifollicular erythema at the superior aspect of the forehead and frontotemporal hairline. A skin biopsy specimen showed a perivascular, lymphocytic infiltrate with periinfundibular fibrosis. These findings established a diagnosis of frontal fibrosing alopecia. The pathogenesis of this condition is poorly understood but may be hormonally-mediated.
