Twenty cases of tuberculous ileo-colitis with radiographic changes seen in the University College Hospital, Ibadan, Nigeria, are reviewed and the clinical features and radiographic patterns examined. The intestinal lesions in all cases were secondary to healed and active pulmonary tuberculosis. Although the ileo-caecal region is the commonest site of involvement, lesions also occurred in the di...

Five hyperplastic outgrowth lines were developed by serial transplantation of hyperplastic alveolar nodules from BALB/cfC3H mice into BALB/c hosts. The lines were used to study the biology, morphology, and virology of premalignant tissue originating in mouse mammary tumor virus (MuMTV)-positive animals. The five lines differed with respect to tumor potential and growth characteristics, corrobor...

Fibrous hyperplastic connective tissue lesions are common in the oral cavity and may be similar both clinically and histologically. A giant cell fibroma, a type of fibrous hyperplasia, was discovered during a preventive patient visit in the dental hygiene clinic at a Midwestern university. The patient, a 19-year-old female, presented with a dome-shaped lesion of normal mucosal color on the atta...

BACKGROUND/AIMS Although gastric hyperplastic polyps are usually considered as benign lesions, a low risk of carcinomatous conversion is currently recognized. We aimed to identify the characteristics of hyperplastic polyps undergoing neoplastic transformation. METHODS A total of 269 gastric hyperplastic polyps from 216 patients removed by endoscopic polypectomy (EP) or surgical resection were...

statement of the problem: soft tissue reactive lesions are the most common lesions of the oral cavity. although many studies have shown the interaction of mast cells with fibroblasts and their participation in fibrosis, the role of mast cells in these lesions is not well understood. purpose: the aim of this study was to evaluate the mast cells (mcs) count in oral soft-tissue reactive lesions in...

We have performed a comparative ultrasequencing study of multiple colorectal lesions obtained simultaneously from four patients. Our data show that benign lesions (adenomatous or hyperplastic polyps) contain a high mutational load. Additionally multiple synchronous colorectal lesions show non overlapping mutational signatures highlighting the degree of heterogeneity between multiple specimens i...

AIM: to estimate the implementation of original method that uses artificial intelligence (AI) detect colorectal neoplasms. MATERIALS AND METHODS: we selected 1070 colonoscopy videos from our archive with 5 types lesions: hyperplastic polyp, serrated adenoma, adenoma low-grade dysplasia, high-grade dysplasia and invasive cancer. Then 9838 informative frames were selected, including 6543 Lesions ...

OBJECTIVES In this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/ computed tomography (SPECT/CT) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. METHODS Five patients with primary hyperparathyroidism (PHPT) and 4 patients with secondary hyperparathyroidism (SHPT) wer...

We measured, by immunohistochemistry, HMGA1 protein expression in 212 breast tissue specimens: 6 normal samples, 28 hyperplastic lesions (13 with cellular atypia), 11 fibroadenomas, 10 in situ ductal carcinomas, 144 ductal carcinomas, and 13 lobular carcinomas. HMGA1 was not expressed in normal breast tissue; HMGA1 staining was intense in 40% of hyperplastic lesions with cellular atypia and in ...

Breast cancer metastasis to the gastrointestinal tract is relatively rare and is generally found when patients complain of symptoms such as gastrointestinal obstruction. Herein, we report a case with metastatic colonic and gastric lesions from breast cancer, with the formation of mucosal polyps which resembled typical hyperplastic polyps.A 47-year-old woman underwent curable surgery for breast ...
