Cutaneous granulomas as the first manifestation of Hodgkin's disease.

We report the case of a 64-year-old male in whom fever, cutaneous rash and hepatomegaly were the first manifestations of Hodgkin disease (HD). Histologically a dense lymphohistiocytic infiltrate with a granulomatous pattern was found in the skin infiltrate. A computed tomography scan revealed hepatosplenomegaly and a small retroperitoneal lymphadenopathy. An hepatic percutaneous biopsy showed a granulomatous infiltration with typical Reed-Sternberg cells. Cutaneous manifestations of HD are briefly reviewed. The authors underline that granulomatous infiltration of the skin as the first manifestation of lymphoma is a very rare feature. We also discuss the possible pathogenic mechanisms of skin granulomas.
