pyoderma gangrenosum is a rare inflammatory skin condition characterized by progressive and recurrent skin ulceration of destructive course. It is usually associated with rheumatoid arthritis, paraproteinemia, myeloproliferative diseases and inflammatory bowel diseases, especially non-specific ulcerative proctocolitis. In these situations, skin lesions are described as concurrent with the intes...

Mosaicism of normal and chromosomally aberrant cells was detected in 14 of 20 spleens from adult New Zealand Black (NZB) mice reared under conventional conditions, a strain that spontaneously develops autoimmunity and lymphoreticular malignancy. No abnormalities were found in marrows from these same animals or in spleens from NZB mice younger than 3 months. The prevalence of chromosomal aberrat...

A 53-year-old male patient with an established diagnosis of IgG multiple myeloma was seen by a hematologist– oncologist in consultation from an outside hospital. He had previously received 1 cycle of chemotherapy treatment, but he was found to be intermittently noncompliant with his therapy. The patient reported occasional nosebleeds and fatigue. Except for a slightly cachectic appearance, the ...

Distal acquired demyelinating symmetric (DADS) neuropathy is clinically characterised by distal motor and sensory disturbances. Typically DADS does not respond or responds poorly to intravenous immunoglobulins (IVIg). We report the case of a 58-year-old patient who developed distal paraparesis. Serum electrophoresis demonstrated monoclonal IgM paraproteinemia having an anti-GM1 but no anti-MAG ...

In the present report we describe a patient with multiple myeloma and long-standing paraproteinemia who developed xanthoma in the absence of an elevation in plasma cholesterol or triglyceride concentrations. Studies demonstrated that our patient's monoclonal IgG antibody interacted with apoprotein B-100. The LDL-antibody complex isolated from our patient did not affect the degradation of LDL by...

Introduction and Aim: The confirmatory step in diagnosis of monoclonal gammopathies is bone marrow biopsy presence M-protein serum protein electrophoresis. These tests are relatively expensive & invasive for screening unavailable low resource settings. Increased levels globulin clue to the gammopathy. aim this study was assess relevance discriminating between patients with without gammopath...
