Two cases of delayed adverse reaction to semi-permanent eyebrow tattoo: Review and case report in Korea for granulomatous reaction

Cosmetic facial tattoo as semi-permanent make-up for the eyebrows is gaining popularity in Korea. Consequently, the incidence of tattoo-related complications, including local skin infections, allergic reactions, and non-allergic granulomatous reactions, is also increasing. Herein, we report two cases of granulomatous reactions to semi-permanent eyebrow tattoos. Clinicians should always keep in mind that both systemic sarcoidosis and delayed complications associated with tattooing can manifest as granulomatous reactions. Therefore, every granulomatous reaction at the tattoo site should be evaluated to differentiate sarcoidosis from foreign body granuloma.
