Sarcoid granuloma on black tattoo.

We report the case of a patient with a black and turquoise tattoo who developed sarcoid granulomas on the areas of black pigment. Patch tests showed a positive reaction to nickel, cobalt, and cadmium; spectrophotometric analysis of the black pigment revealed the presence of nickel and cobalt among other metals. Although the pathogenesis of sarcoid granulomas is unknown, it seems that a delayed type hypersensitivity reaction is one of the mechanisms involved.

Presence of perineuritis in a case of papular purpuric gloves and socks syndrome associated with mononeuritis multiplex attributable to B19 parvovirus.

A previously healthy 16-year-old boy developed papular purpuric gloves and socks syndrome concomitant with mononeuritis multiplex attributable to acute infection with parvovirus B19. A cutaneous biopsy showed lymphocytic lichenoid vasculitis and perineuritis. We discuss the relevance of these pathologic findings, and we suggest a correlation with the patient's neurologic condition. This case illustrates the difficulties in differentiating dysesthesia accompanying cutaneous manifestations of exanthem from neurologic disease on the basis of the clinical appearance alone.
