Tattoo Rash

Ayoola et al report a previously healthy 32-year-old man, who presented with 27-kg weight loss over the course of 1 year, dyspnea, nonproductive cough, subjective fevers, night sweats, and painful hematuria. He had tattoos placed 3 years before presentation and noticed skin lesions confined to his tattoos 1 year ago. The key features of this patient's clinical presentation that are concerning for sarcoidosis include hypercalcemia, bilateral hilar lymphadenopathy, and skin lesions along his tattoos. Sarcoidosis, a noninfectious process, commonly involves the lungs, eyes, and skin but can affect any organ. Sarcoidosis is diagnosed by clinical, radiological, and histological findings.
