Nontuberculous (atypical) mycobacteria rarely cause skin and soft tissue infections. Tattooing with contaminated gray ink has been implicated in previously reported outbreaks. We report the case of a 39-year-old Hispanic male who presented with a refractory, pruritic, papular eruption within the distribution of his tattoo with punch biopsy demonstrating papillary dermal granulomatous and suppurative inflammation surrounding small collections of acid-fast bacilli with associated superficial and deep dermal perivascular lymphatic inflammation, consistent with nontuberculous mycobacterial infection. Although uncommon, clinicians should consider nontuberculous mycobacterial infection in the differential diagnosis of refractory tattoo-associated skin eruptions.

Abstract Nontuberculous mycobacteria (NTM) infect children with increasing frequency worldwide. Using blood and lymph node tissue from children with NTM lymphadenitis, and uninfected lymph node tissue from community controls, we evaluated helper T (TH) cells in functional assays of TH1/TH17 differentiation and measured the concentration of their associated cytokines at the site of infection. Circulating TH cells from infected children were attenuated in their TH1/TH17 differentiation capacity and expressed less interferon γ and interleukin 17 after polyclonal stimulation. Similar differences were observed at the site of infection, where most cytokine concentrations were unchanged relative to controls. Our data are consistent with a model wherein TH1/TH17 differentiation is attenuated in NTM-infected children.
