Plasmablastic immunoglobulin-secreting lymphoma. Report of a case and a glimpse at the prognosis.

The case of a 57-year-old patient with a plasmablastic lymphoma is described. The primary diagnosis was an ordinary plasmacytoma, type IgG kappa. The final course of the disease involved almost all of the organs. The clinical aspect was determined by multiple skin infiltrations. The present report has in common with other published cases the fact that multiple secondary skin involvement of immunoglobulin-secreting tumors, regardless of their origin, have a very poor prognosis. In comparison, primary multiple cutaneous immunoglobulin-secreting tumors have a better prognosis.
