ABSTRACT
Decorative tattoos are associated with a variety of adverse cutaneous reactions. We describe a unique fibrosing vasculitic reaction to red tattoo ink. The histopathology was similar to that in localized chronic fibrosing vasculitis (LCFV), but sharply limited to sites of red tattoo ink injection and associated with florid verrucoid epidermal hyperplasia. LCFV has been described in a broad variety of slowly progressive disorders with a firm consistency such as erythema elevatum diutinum, plasma cell granuloma, granuloma faciale, and IgG4-associated sclerosing diseases. It has been hypothesized that LCFV is the result of maladaptive immune reaction with failure to clear the causative antigen. To the best of our knowledge, this is the first case of LCFV associated with tattoo. We speculate on the implications our case holds for the pathogenesis of LCFV.
