[Frontal fibrosing alopecia with androgenetic pattern. A diagnostic challenge - a therapeutic problem]

Diagnosis of scarring alopecia is a particular diagnostic and therapeutic challenge. Frontal fibrosing alopecia was first described by Kossard as a scarring alopecia characterized by progressive recession of the frontal-temporal hair margins leading to permanent alopecia. Primarily affected are postmenopausal women. A 56 year-old woman presented with fibrosing alopecia in a male-pattern distribution. Evaluation of medical history, clinical, dermoscopic and histopathological findings led us to the diagnosis of frontal fibrosing alopecia with additional androgenetic pattern. Other forms of scarring alopecia have to be considered as differential diagnoses. This case emphasizes that dermoscopy of the scalp should become an integral part of the diagnosis of scalp diseases.
