A follow up study with biopsy was initiated in 1982 to define the relations between variants of intestinal metaplasia and the evolution of chronic atrophic gastritis and gastric ulcer. All patients (58 with chronic atrophic gastritis and 66 with gastric ulcer) had intestinal metaplasia at the start of the study. In the six year period to 1988 a total of 241 biopsies were performed on the patien...

PURPOSE Although intestinal metaplasia is often found in association with adenocarcinoma of the urinary bladder, it is unclear whether intestinal metaplasia of the bladder is a premalignant lesion. Telomere shortening has recently been implicated in epithelial carcinogenesis. We used quantitative fluorescent in situ hybridization (FISH) to measure telomere length and UroVysion FISH to detect cy...

Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. CASE PRESENTATION 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified ...

CASE PRESENTATION A 36-year-old woman presented to the Women's Hospital, School of Medicine, Zhejiang University with vaginal bleeding and infertility resulting from osseous metaplasia nodules of the submucosa and mesosalpinx after a first trimester a...

Despite a significant decrease in the incidence of gastric cancer in Western countries over the past century, gastric cancer is still one of the leading causes of cancer-related deaths worldwide. Most human gastric cancers develop after long-term Helicobacter pylori infection via the Correa pathway: the progression is from gastritis, atrophy, intestinal metaplasia, dysplasia, to cancer. However...

different forms of foreign-body irritation and of vitamin A deficiency to squamous metaplasia in the bladders of rats was reported. It is also known that estrogens will cause squamous metaplasia. The metaplasia following estrogen administration has been described in various organs of the genito urinary system in different species (SO). It has been found in the uterus (@,17, 19), and the mets pl...

Nephrogenic metaplasia (or nephrogenic adenoma) and clear cell adenocarcinoma of the bladder are uncommon lesions that cause diagnostic dilemmas for pathologists due to their similar morphologic features. Nephrogenic metaplasia describes a lesion in the lower urinary tract that is composed of small tubules resembling renal medullary tubules. It has been suggested that nephrogenic metaplasia may...

Phyllodes tumors are rare fibroepithelial neoplasms of the breast, classified as benign, borderline, or malignant based on histological features. Osseous metaplasia, characterized by presence bone formation within tumor, is an uncommon finding. This case report highlights rarity osseous metaplasia in a benign phyllodes tumor. A 23-year-old female presented with gradually enlarging lump left bre...

BACKGROUND Squamous metaplasia refers to the pathological transformation of the urothelium leading to nonkeratinised stratified squamous metaplasia (N-KSM). OBJECTIVE To present our experiences in the diagnosis and treatment of N-KSM of the urinary bladder in children. MATERIALS AND METHODS In this study, we present our experiences in the diagnosis and treatment of N-KSM of the urinary blad...
