[Chronic follicular mucinosis. Presentation of a case].

Follicular mucinosis is a not uncommon but frequently misidentified disease. Actually this peculiar condition is divided in three groups: in one group the lesion cleared spontaneously within a few months (acute follicular mucinosis); in a second group there is a chronic relapsing but benign course over several years (chronic follicular mucinosis) and in a third group appeared in association with a lymphoma (15%). Some Authors believe that follicular mucinosis is a histological term for a reactive pattern in follicular epithelium. We report the case of a patient affected by this dermatosis. The eruption consisted of follicular papules and inflammatory plaques widespread. No instance of transition from follicular mucinosis to lymphoma was observed. Very important to the diagnosis was the histological findings. We believe that the case in exam was a form of chronic follicular mucinosis.
