Primary cutaneous Hodgkin's disease with evolution to systemic disease. Association with the Epstein-Barr virus.

Hodgkin's disease rarely involves the skin and when it does is an indication of advanced stage disease. Primary cutaneous Hodgkin's disease is exceedingly rare, and only a few cases are reported. We describe a patient who developed multiple cutaneous lesions of Hodgkin's disease 2 years before manifesting nodal disease of mixed cellularity subtype. Reed-Sternberg cells in the skin as well as lymph nodes and bone marrow were positive for Epstein-Barr viral transcripts and expressed viral latent membrane protein. Epstein-Barr virus has not previously been demonstrated in primary cutaneous Hodgkin's disease, and its presence in lesions in all sites in this case supports a diagnosis of primary cutaneous disease with subsequent evolution into systemic disease.
