There were grouped reddish and yellow-brown infiltrative papules, some of which coalesced into plaques scattered over the tattoo (Figures 1a,b).
Enhanced computed tomography (CT) of the chest with contrast demonstrated a few diffuse reticulonodular opacities in the bilateral lower lobe, bilateral hilar lymph nodes enlargement [the arrows in panels (a,b)], and in the posterior segment of the right upper lobe are some small ground glass nodules.

Enhanced computed tomography (CT) of the chest with contrast demonstrated a few diffuse reticulonodular opacities in the bilateral lower lobe, bilateral hilar lymph nodes enlargement, and in the posterior segment of the right upper lobe are some small ground glass nodules (Figures 2a,b).
Histopathological examination demonstrated non-caseating granulomas with pigment granules and mild lymphocytic infiltration. Black tattoo pigment is seen throughout the granuloma [the arrows in panels (A,B)] [Hematoxylin-Eosin, original magnification x4 (A), x20 (B)].

A biopsy of yellow-brown plaque within the eyebrow tattoo indicated non-caseating granulomas throughout the dermis consistent with a diagnosis of cutaneous sarcoidosis (Figures 3A,B). Throughout the granuloma, black tattoo pigment was discovered (the arrows in Figures 3A,B).
