• Cutaneous involvement in multiple myeloma (MM) is extremely rare. It may correspond to plasmocytomas, secondary amyloidosis, paraneoplastic syndromes or drug reactions. We report a 75-year-old female with skin lesions, corresponding to extramedullary plasmacytomas (EPs), as a manifestation of MM progression. Most EPs appear in the upper airway and gastrointestinal tract, but have also been described in the genitourinary tract, lung, kidney, thyroid and in 2% of cases, in the skin. Cutaneous lesions are generally associated with terminal stages of the disease and a poor prognosis.
