Light and electron microscopic study of synovial specimens from four patients with the Milwaukee shoulder syndrome disclosed vascular congestion, villous and focal synovial lining cell hyperplasia, occasional giant cells, and fibrin deposition both within and on the surface of the synovium. Although these changes are non-specific, the finding of basic calcium phosphate crystal aggregates in all...

Focal haematopoietic hyperplasia is a rare and localized proliferation of the bone marrow to such an extent that it produces a tumor-like expansion hence called as pseudotumor. Radiologically it presents as an osteolytic expansile mass and may mimics with certain bony tumors. We report a case of Focal haematopoietic hyperplasia in the 3rd anterior rib of a 45 year old man clinically presenting ...

Focal nodular hyperplasia is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, surgical resection may be required for diagnostic reasons or symptomatic patients. Depending on the anatomic location of t...

Mobile phone usage has increased greatly over time, and there is also the proliferation of models by different manufacturers, some which are known to produce popular brands while other manufacturers unknown have been identified. So many health conditions associated with radiation emitted from mobile phones communication gadgets. Such condition as glioma, schwannoma, degenerative tissue reported...

While the rat pancreas is susceptible to experimental cancer induction, the spontaneous incidence of pancreatic cancer in this species is reported to be very low. However, we observed unusually high incidences of focal acinar hyperplasia and acinar adenoma in vehicle control male F344/N rats of some NCI/NTP 2-year toxicological studies. The vehicle in these studies was corn oil given by gavage....

Pituitary tumor-transforming gene (PTTG), a securin protein isolated from pituitary tumor cell lines, is highly expressed in invasive tumors and exhibits characteristics of a transforming gene. To determine the role of PTTG in pituitary tumorigenesis, transgenic human PTTG1 was targeted to the mouse pituitary using the alpha-subunit of glycoprotein hormone. Males showed plurihormonal focal pitu...

Verruco-papillary lesions (VPLs) of the oral cavity described in the literature involve a spectrum of conditions including squamous papilloma, verruca vulgaris, focal epithelial hyperplasia, condyloma, proliferative verrucous leukoplakia and verrucous carcinoma. A majority of the VPLs are slow growing, benign in nature and have a viral aetiology. Virus associated benign mucosal outgrowths are ...

Introduction. Currently, there are limited papers on changes in the pseudostratified ciliated columnar epithelium of sinonasal tract chronic inflammatory processes, particularly basal cell hyperplasia. The latter is similar to dysplasia varying severity stratified squamous nonkeratinized epithelium. Studying can clarify histogenesis various epithelial tumors tract, including papillomas. researc...

AIM Tropical sprue was considered to be the most important cause of malabsorption in adults in India. However, several reports indicate that celiac disease is now recognized more frequently. METHODS We analyzed the clinical presentation, endoscopic and histological features of 94 consecutive patients (age >12 years) with chronic diarrhea and malabsorption syndrome. The spectrum of disease in ...

Studies of prostate cancer pathogenesis and development of new therapies have been hampered by a lack of appropriate mouse models. We have generated PSA-Cre-ER(T2) mice that express the tamoxifen-dependent Cre-ER(T2) recombinase selectively in prostatic epithelium, thus allowing us to target floxed genes selectively in epithelial cells of fully differentiated prostate of adult mice and to modul...
