Abstract

The skin is a possible site of extramedullary localization in multiple myeloma (MM) patients; however, the mechanisms involved in this process are poorly understood. We describe the case of a refractory MM patient who developed a cutaneous localization under bortezomib treatment and we further expanded observations in other eight MM patients. We focused on the expression of genes involved in plasma cell skin homing, including CCR10, which was highly expressed. Moreover, we observed a lack of CXCR4 surface expression and the down-regulation of ICAM1/CD54 throughout the progression of the disease, suggesting a possible mechanism driving the escape of MM cells from the bone marrow into the skin. © 2016 The Japanese Society of Hematology
