We report a case of localized linear IgA dermatosis (LID). The patient suffered from herpes zoster on the right waist and received three localized ultraviolet (UV) light treatments. One month later he presented with bullae on the same site. Direct immunofluorescence showed deposition of linear IgA and weak C3 along the basement membrane zone. Indirect immunofluorescence on the salt‐split human skin demonstrated that IgA antibodies were bound to the epidermal side. To our knowledge, this is the first case of localized LID induced by UV light treatment for herpes zoster. It is also the third case of LID induced by UV light.
