[Extragenital lichen sclerosus et atrophicus: about a case].

Lichen sclerosus et atrophicus is a chronic inflammatory dermatosis, characterized by a specific external genital mucosal tissue tropism. Isolated cutaneous manifestation is rare. We report a case of lichen sclerosus et atrophicus in a woman with purely cutaneous involvement, in order to highlight the importance of evoking this diagnosis in the absence of obvious genital involvement.

We report the case of bronchial carcinoma revealed by metastatic skin nodules on the scalp. This fairly common mode of discovery is often associated with poor prognosis. This study aims to underline the importance of directing the search for a primary lung cancer in cases of secondary skin involvement.
