Malignant gastrointestinal stromal tumor in association with Russell body gastritis-A case report.

Russell body gastritis (RBG) is an unusual form of chronic inflammation characterized by accumulation of plasma cells containing Russell bodies (RB) in the gastric mucosa. Although its pathogenesis has not been fully evaluated, there is evidence to support a strong association with Helicobacter pylori infection. Only four cases of RBG in association with malignant epithelial gastric tumors were reported.

Eosinophilic metaplasia in transurethral resection of the prostate.

Background: To investigate prostatic eosinophilic metaplasia (EM) in a large series of cases and their relationship with the basic prostate pathology in TURP-material: benign prostatic hyperplasia (BPH), National Institutes of Health category IV prostatitis (also called histologic prostatitis or HP), and prostatic adenocarcinoma (PCa).

Aim: The relation between EM and basic prostate pathology: BPH, PCa, and HP.

Materials And Methods: Around 61 consecutive TURP-specimens were reviewed for the presence of EM.

Histopathology of nonspecific granulomatous prostatitis with special reference to eosinophilic epithelial metaplasia: Pathophysiologic, diagnostic and differential diagnostic correlations.

Background: Recently, we publish two case reports about association of nonspecific granulomatous prostatitis (NSGP) and eosinophilic metaplasia (EM) in benign prostatic epithelium. There is no investigation of large series of this association in medical literature. Aim of the current study is to investigate the frequency of association of NSGP and prostatic EM in a large series of cases and their relationship with the basic prostate pathology: benign prostatic hyperplasia (BPH), National Institutes of Health-category IV prostatitis (so-called histologic prostatitis (HP)), and prostatic adenocarcinoma (PCa).

Nonspecific granulomatous prostatitis in association with eosinophilic epithelial metaplasia and prostatic adenocarcinoma.

We present the first case of nonspecific granulomatous prostatitis (NSGP) associated with both eosinophilic epithelial metaplasia (EM) in benign glands and prostatic adenocarcinoma (PCa). The patient was a 68-year old man with a history of obstructive prostatic syndrome. After a transurethral resection of the prostate, the histologic analysis revealed NSGP and PCa.

LAMPs and ABH histo-blood group antigens in granulation tissue.

Endothelial cells are major participants in angiogenic processes accompanying wound repair. The functions of ABH histo-blood group antigens (HBGAs) and lysosome-associated membrane proteins LAMP-1 and LAMP-2 in endothelial cells of granulation tissue are currently unkown. Here we hypothesize that HBGAs and LAMPs enrich the phenotypic characteristics of endothelial cells and might be implicated in the plasticity of granulation tissue.

Hyaline globules (thanatosomes) in gastrointestinal epithelium: pathophysiologic correlations.

Hyaline globules (HGs; thanatosomes) are well-defined morphologic and functional entities representing a degenerative phenomenon common to all cell types. We present the first quantitative and qualitative study of HGs in normal and pathologic gastrointestinal (GI) epithelium from a series of 2,230 biopsies. HGs were very rarely found in normal epithelium (1.
