Microblading-Induced Granulomatous Reaction: Case Report and Review of the Literature.

Microblading is a common cosmetic procedure that can modify the appearance of one's eyebrows. Although generally well-tolerated, the procedure can cause a number of dermatologic issues; on rare occasions, granulomatous reactions can manifest. We use this case to highlight a presentation of a nonsarcoidal granulomatous dermatitis and review the literature on granulomatous reactions secondary to microblading. Of the 21 cases included in our review, approximately half (10/21) were diagnosed with foreign-body granulomas and the other half with sarcoidosis (7 of 21 with systemic sarcoidosis and 4 of 21 with cutaneous sarcoidosis). Although microblading remains a commonplace cosmetic technique, it is not without risk. Much like other types of tattoos, microblading can cause granulomatous reactions for which we must be vigilant, and further workup for sarcoidosis might be considered in select patients.
