The specific skin locations of @entity1582 (M. M.) and @entity8057 (M. W.) are rare. The authors report here 4 cases: 2 within M. M., the other 2 within @entity706 with @entity23694 (M. W.) or in situ tumoral secretion of IgM. Observation no. 1. A 56-year-old @entity1 is admitted for investigations for spontaneous @entity174 of the ribs. The skin examination reveals about ten purple, nodular and sometimes ulcerated lesions of the back which appeared over more than one year. The histology of a cutaneous nodule shows a dense infiltrate of plasma cells with numerous atypical cells. The laboratory investigations reveal a IgG, kappa M. M. A polychemotherapy leads to a healing of the nodules in 3 months. Observation no. 2. A 58-year-old @entity1 is admitted for investigations of a @entity644 (6.80/24 h) which will be imputed to a lambda chains M. M. One year and a half later appear subcutaneous thoracic nodules. The histology of the skin confirms the diagnosis of metastatic @entity272 ; the @entity1 will die a few months later in spite of the chemotherapy. Observation no. 3. A 84-year-old @entity1 is admitted for investigations of a dysglobulinemia. On the cutaneous part there are tumoral purple plaques symmetrically disposed on the 2 cheeks and the nose. The histology of the skin shows a dermo-hypodermal tumoral infiltrate essentially made of lymphoplasmocytoid cells. In direct immunofluorescence study there is a kappa tumoral secretion of mu type.(ABSTRACT TRUNCATED AT 250 WORDS)
