UNLABELLED The synchronous occurrence of two different neoplasias is an uncommon event, which may arise between tumors originating in the same organ or in cancer-to-cancer metastasis. We report a rare case of chronic lymphocytic leukaemia / small lymphocytic lymphoma associated with a cutaneous metastatic squamous cell carcinoma in a cervical lymph node. In the affected lymph node, it was obser...

BACKGROUND AND AIMS It is not known whether lymphocytic colitis and collagenous colitis represent different clinical entities or constitute part of a spectrum of disease. METHODS Detailed clinical features and histological findings were compared in a large series of patients with confirmed lymphocytic and collagenous colitis. RESULTS Histological diagnosis was confirmed in 96 patients with ...

In the present investigation, the prevalence of focal lymphocytic adenitis in the submandibular salivary gland was observed in a series of 116 postmortem subjects after suitable exclusions had been made. Focal lymphocytic adenitis could not be demonstrated in the labial salivary glands. The degree of lymphocytic infiltration in the labial salivary glands is positively correlated with the level ...

Background: B-cell chronic lymphocytic leukemia is the most frequent leukemia in the western world while T-cell large granular lymphocytic leukemia with cytotoxic (CD8+/CD3+CD4-) immunophenotype is rare. There is much ongoing interest regarding the interaction between T cells and B-cell chronic lymphocytic leukemia cells. Methods: Peripheral blood and bone marrow samples from a 72 year-old-man ...

background: nowadays, drug and observation are advised to patients with lymphocytic hypophysitis and in some cases with nonfunctioning pituitary macoadenoma, instead of surgery. case presentation: in this article, we report a woman with nonfunctional pituitary macroadenoma and panhypopitutarism and negative criteria for lymphocytic hypophysitis associated with increased liver enzymes. after thr...

The present investigation describes the spontaneous pathological lesions in urinary bladders (n = 177) of slaughtered buffaloes collected from Northern India. Gross examination revealed congestion, haemorrhages, oedematous changes and thickening mucosa. Microscopically, epithelial abnormalities, inflammatory neoplastic conditions were noticed. Epithelial abnormalities included hyperplasia, von ...

The importance of the tumor microenvironment in chronic lymphocytic leukemia is widely accepted. Nevertheless, the understanding of the complex interplay between the various types of bystander cells and chronic lymphocytic leukemia cells is incomplete. Numerous studies have indicated that bystander cells provide chronic lymphocytic leukemia-supportive functions, but it has also become clear tha...

The lymphocytic growth hormone (GH) and nitric oxide (NO) levels were studied among three different age groups of cattle viz. cyclic adult cows (3-8 years of age), young female calves (2 weeks old) and growing female calves (6 months old). The effects of leptin, sodium nitroprusside (SNP) and N-nitro-L-arginine methyl ester (L-NAME) on the secretion of lymphocytic GH and NO were also studied. L...

Chronic lymphocytic leukemia is a disease with up-regulated expression of the transmembrane tyrosine-protein kinase ROR1, a member of the Wnt/planar cell polarity pathway. In this study, we identified COBLL1 as a novel interaction partner of ROR1. COBLL1 shows clear bimodal expression with high levels in chronic lymphocytic leukemia patients with mutated IGHV and approximately 30% of chronic ly...
