BACKGROUND the phenomenon that histiocytic/dendritic cell sarcomas may be transformed from lymphoproliferative diseases is dubbed 'transdifferentiation'. Langerhans cell sarcoma (LCS) transdifferentiated from chronic lymphocytic leukemia/small cell lymphoma (CLL/SLL) is extremely rare. The underlying mechanisms of LCS tumorogenesis and its(More)
Sparse code multiple access (SCMA) is a new nonorthogonal multiple access scheme, which effectively exploits the shaping gain of multi-dimensional codebook. In this paper, a multi-dimensional SCMA (MD-SCMA) codebook design based on constellation rotation and interleaving method is proposed for downlink SCMA systems. In particular, the first dimension of(More)
Here we describe a case of Clostridia glycolicum (C. glycolicum) bacteremia in a bed-ridden elderly man with chronic illnesses. The bacterium was identified by the Remel RapID ANA II System. We believe that this is the fifth published report of human illness caused by this bacterium. In the four previously reported cases, C. glycolicum was found in cultures(More)
Polypoid mass in the prostatic urethra is uncommon, yet the disease entities are so heterogeneous that the spectrum ranges from congenital malformations, benign polyps, to various malignancies. Prostatic urethral polyp (PUP) is a rare benign overgrowth of prostatic parenchyma protruding into prostatic urethra, and correspondingly, prostatic ductal carcinoma(More)
Tumor-induced osteomalacia (TIO) is typically caused by phosphaturic mesenchymal tumor (PMT) that secretes the phosphaturic hormone, fibroblast growth factor-23 (FGF23), resulting in decreased phosphate reabsorption in kidneys, hypophosphatemia, and finally osteomalacia. Rare cases of malignant tumor manifesting with TIO other than PMT had been reported,(More)
Fibrous dysplasia is a benign intramedullary lesion characterized by an excessive proliferation of cellular fibrous tissue intermixed with irregular trabeculae. It involves any of the bones presenting as monostotic, polyostotic, or panostotic lesion. It is caused by mutation in the GNAS1 gene (20q13.2, encoding a G-protein) resulting in inhibition of(More)
BACKGROUND Dysmegakaryocytopoiesis in patients with the plasma cell neoplasm (PCN) is rarely discussed in the literature. The puzzling phenomenon, which PCN patients maintaining normal platelet count even when the marrow is mostly replaced by plasma cells, is hardly explored. AIM This study was aimed to determine the frequency of dysmegakaryocytopoiesis(More)
Richter’s Transformation of chronic lymphocytic leukemia (CLL) to diffuse large B-cell lymphoma or Hodgkin lymphoma (both are B-cell origin) are well described in literature. Recently, transformation of CLL into histiocytic/dendritic/Langerhans cell sarcoma (all are myeloid origin), dubbed as “transdifferentiation”, has also been reported. The mechanisms(More)
