A man 60 years old suddenly developed hard nodules in a tattoo that had been placed 45 years ago. The interest of the case lies in the following points: (1) the histopathology of a biopsied specimen was that of a sarcoid reaction; (2) lung changes were subsequently found that were interpreted as pulmonary sarcoidosis; and (3) the cutaneous lesions began to flatten after the biopsy was taken, and within four months both they and the lung changes had disappeared.
