Description
Tattoos sit in skin for life, and skin disease can find them. Rucha Herlekar, Apoorva Sharma, and Sunil Dogra report an unusual case in a 2026 paper. A 21-year-old woman with a three-year history of psoriasis developed red plaques exactly on her tattooed skin, two years after the tattoos were done.
Her ordinary psoriasis elsewhere had cleared months earlier, which made the tattoo-only outbreak puzzling. The doctors weighed several explanations: psoriasis homing to injured skin, a granulomatous reaction to the ink, a lichenoid reaction, or tattoo sarcoidosis. A biopsy showed noncaseating granulomas with ink pigment in the skin. The case shows how tattoo reactions can mimic a flare of the underlying disease.
