Cutaneous involvement in relapsed multiple myeloma

Abstract

Abstract Cutaneous involvement in multiple myeloma with extramedullary disease is rare. We report the case of a refractory multiple myeloma patient who developed a cutaneous lesion. Histopathology revealed dermal immature plasma cell infiltrate with a lack of CD138 expression. This cutaneous location was associated with an aggressive clinical course and short survival.
