A rare case of follicular sarcoidosis

Abstract

The article is devoted to a rare variant of skin sarcoidosis the so-called follicular sarcoidosis. According to the literature, the follicular form of sarcoidosis is extremely rare, several isolated cases are described in foreign literature, there are no publications in the russian literature. A 30-year-old female patient came to the clinic of the Military Medical Academy with a skin rash of the upper extremities, trunk and neck that lasted for one year. Anamnesis: repeated use of topical corticosteroids for the treatment with a temporary positive effect. The skin process was represented by common follicular papules; a histological examination of one of the elements revealed granulomas of the sarcoid type, which were located perifolliculary, mainly around the infundibular sections of the hair follicles. The rash resolved after a course of external corticosteroid therapy. The clinical case described by us illustrates the need for histological examination to verify the diagnosis.
