[Cutaneous plasmacytosis and polyclonal cryo-immunoglobulinemia].
A 65-year-old male patient is described who presented with (1) large violet cutaneous plaques on the left side of the body, characterized by dense plasmocyte infiltration of the dermis which appeared benign and largely negative to immunofluorescence, (2) massive polyclonal cryoglobulinemia (type III) without paraproteins, and (3) intermittently marked peripheral monocytosis and thrombopenia without significant medullary changes. Compared with the cases reported in the literature, and after a thorough immunological investigation, this syndrome cannot be entirely assimilated to any entity described up to the present time. Hypothetically, a reactional disorder is the most likely.
