CUTANEOUS PLASMACYTOSIS - REPORT OF A CASE IN A WHITE MAN

We describe a 40-year-old white man with a peculiar skin eruption in a ssociation with polyclonal hypergammaglobulinemia. No underlying disea se was detected. A skin biopsy specimen showed a proliferation of matu re plasma cells intermingled with some lymphocytes and histiocytes, an appearance consistent with cutaneous plasmacytosis. This disease had been previously described only in Japanese patients. In our patient th e disease progressed slowly. Lymph node infiltration by mature plasma cells was later noted.
