ABSTRACT

Langerhans histocytosis is a rare disease, which can affect one or several organs and the classification depends on this. It can be localized or disseminated and the treatment is adapted to each patient. The clinical manifestations are very varied due to the wide range of affectation of the patients. In case of persistent seborrheic dermatitis that does not respond to the initial diagnostic/therapeutic approach, trichoscopy and biopsy are mandatory. In scalp it can manifest with scarring alopecia plaques, in addition to papular and ulcerative lesions in folds, the main characteristic being that they are recalcitrant to usual treatments.
This article presents the case of an adult male patient, whose main manifestations are on the skin and mainly on the scalp. The most frequently described findings in the literature are inflammatory lesions with a seborrheic appearance, yellowish crusty plaques, and scaling. This case is not exception, however, it also presents scarring alopecia, which is infrequent, and we highlight the trichoscopic findings, which very little has been described.
