Multinucleate cell angiohistiocytoma (MCAH) was first described by Smith and Wilson-Jones in 1985. It is an uncommon entity but probably underdiagnosed because of lack of recognition by clinicians and pathologists. We report a 47-year-old man with asymptomatic grouped violaceous papules on the dorsum of the hands for 3 years. The histopathological and immunopathological features of our case revealed characteristics of MCAH similar to the initial description of Smith and Wilson-Jones and other reports.
