Disseminated cutaneous sarcoidosis triggered by eyebrow tattoo: a case report highlighting lesions beyond tattooed sites.

Sarcoidosis is a multisystem granulomatous disease commonly involving the lungs and lymph nodes, but it may also affect the skin. Tattoos have been recognized as potential triggers for cutaneous sarcoid lesions. We report a case of a 46-year-old female who developed sarcoidosis presenting as asymptomatic papules and plaques initially confined to her tattooed eyebrows, followed by the appearance of similar lesions at distant non-tattooed sites, including the upper back and elbows. Histopathology confirmed cutaneous sarcoidosis, and imaging revealed bilateral hilar lymphadenopathy, indicating systemic involvement. The patient responded well to systemic corticosteroid therapy after topical treatment failed. This case highlights the unique phenomenon of sarcoid skin lesions occurring beyond tattoo sites, emphasizing the systemic nature of the disease and the importance of thorough clinical evaluation and management.
