A 29-year-old woman and 2 men, 24 and 26 years old, presented with rapidly growing lesions that appeared after a tattooing session. Clinical examination showed several brown papules located on tattoos on the shoulder, arm, and flank, respectively (Figure 1). Dermoscopic examination of patients 2 and 3 revealed generalized “fat fingers” (Figure 2). Histopathologic analysis showed a basaloid cell proliferation with varying amounts of hyperkeratosis and acanthosis. A cellular infiltrate with macrophages containing inorganic pigment around dermal vessels was also evident (Figure 3).
