Frontal Fibrosing Alopecia in Men: Presentations in 12 Cases and a Review of the Literature. / Alopecia frontal fibrosante en el varón: presentación de 12 casos y revisión de la literatura.

ABSTRACT

BACKGROUND: Frontal fibrosing alopecia (FFA) is a scarring disease in which the hairline recedes and the eyebrows can be affected. Usually seen in postmenopausal women, FFA is much less common in men. OBJECTIVE: To describe the clinical characteristics of FFA in a case series of men and compare this series to those reported in the literature. MATERIAL AND METHODS: Men with FFA being treated in our dermatology department from January 2010 to December 2015 were included prospectively for this descriptive study. We collected patient information and clinical and treatment characteristics. RESULTS: Twelve men (mean age, 75 years) were recruited. Alopecia was the reason for seeking medical care in only 4 cases. The hairline had receded 3cm on average. Half the patients had facial papules, and 83% had androgenetic alopecia or hair loss on eyebrows or extremities. Follicular hyperkeratosis and erythema were present in 66%, and only 25% of the men reported pruritus. The most commonly prescribed treatments were topical corticosteroids in 8 patients (66%) and minoxidil in 4 (33%). CONCLUSIONS: Facial papules, androgenetic alopecia, and loss of body hair are more often observed in men with FFA than in women. The men in this series were older on average than in other FFA case series in the literature, possibly accounting for the higher prevalence of associated androgenetic alopecia and the fact that most of these men were seeking care for conditions other than hair loss.
