[Postmenopausal frontal fibrosing alopecia. Report of 3 cases].

Postmenopausal frontal fibrosing alopecia is a rare aspect of scarring alopecia concerning elderly women. It appears as a receding anterior hair line localised in the frontal and temporal regions. It is a particular pathologic and clinical form of lichen planopilaris. The histologic aspect is that of a lichenoïd inflammatory infiltrate affecting the dermal follicular junction, accompanied by a fibrous scarring aspect, the latter contributing to the diagnosis and individualization of this entity. Discoïd lupus erythematous is the main histologic differential diagnosis. Postmenopausal period is the only associated condition found in affected women. Evolution is unpredictable and does not seem to be modified by treatment.
