One of the earliest descriptions neuralgia dates back to John Fothergill in 1773.1 However, concept nerve pain can be traced physicians like Rhazes (d. 925), Haly Abbas 982), Avicenna 1037), and Jorjani 1137) who discussed multiple aspects neuropathic including its classification, etiology, differentiating characteristics, qualities, pharmacologic nonpharmacologic treatments.2 Currently, neurop...
Idiopathic thrombocytopenic purpura (ITP) may be associated with other autoimmune diseases and the development of lymphoproliferative malignancies. In Sjögren's disease, Graves' disease, and essential mixed cryoglobulinemia, which are also associated with the development of B-cell neoplasia, clonal B-cell expansions have been detected. Eleven patients with ITP were investigated for the presence...
IgM myeloma is a rare hematologic malignancy for which the clinicopathological features and patient outcomes have not been extensively studied. We carried out a multicenter retrospective study in patients with diagnosis of IgM myeloma defined by >10% marrow involvement by monoclonal plasma cells, presence of an IgM monoclonal paraproteinemia of any size, and anemia, renal dysfunction, hypercalc...
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 77-year-old man visited our hospital complaining of fever, excessive sputum production, and dyspnea. immature plasma cells (plasmablasts), accounting for 58% of the leukocytes, and marked rouleaux formation (A). Interestingly, rouleaux formation of the neo...
BACKGROUND AND OBJECTIVES The occurrence of two or more cases of multiple myeloma (MM) in the same family has been reported from time to time. The current study is the first population- and cancer-registry-based survey to investigate familiality of premalignant or malignant B-cell proliferation. DESIGN AND METHODS A family registry of 218 multiple myeloma cases was compared with the records o...
The role of anti-peripheral nerve myelin antibody (anti-PNM Ab) in the pathogenesis of acquired demyelination of peripheral nerve is unclear, in part, due to the poor correlation between antibody and disease activity. Previous studies show that only 27-50% of patients with acute demyelinating neuropathy or Guillain-Barré syndrome (GBS) had serum Abs to peripheral nerve or PNM as demonstrated by...
This report describes a unique case of coexisting necrobiotic xanthogranuloma and chronic lymphocytic leukemia in a patient presenting with scleritis and uveitis. A 53-year-old Caucasian man diagnosed with anterior uveitis and scleritis for the prior year was referred to our uveitis clinic for further evaluation. Prior uveitis/scleritis workup performed by the referring ophthalmologist was nega...
Waldenström macroglobulinemia (WM) and its associated hyperviscosity syndrome (HVS) are generally caused by lymphoplasmacytoid lymphoma or other small B-cell lymphoproliferative disorders. WM associated with extranodal marginal zone B-cell-mucosa-associated lymphoid tissue lymphoma (EMZL/MALT-type) has not been emphasized. We describe 4 men and 2 women (age, 40-79 years) with clinical and labor...
Several studies have suggested a pathogenetic role of paraproteinaemias in PNS damage. Over the few last years, the presence of symptomatic or subclinical PNS lesions in CNS diseases like multiple sclerosis has been described. On the other hand, CNS demyelinating lesions and cervical atrophy have been reported in patients affected by chronic inflammatory demyelinating polyradiculoneuropathy (CI...
