Diffuse myoepithelial hamartoma of the duodenum associated with adenocarcinoma
Abstract:
A 56-year-old man presented with obstructive jaundice was found to have diffuse cystic glandular malformation of the second part of the duodenum, in association with adenocarcinoma of the periampullary area. Comparison of the pathological findings with myoepithelial hamartoma and diffuse cystic glandular malformation of the stomach reveals resemblances and differences.

Barrett Esophagus-I: Introduction
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Cellular Adaptation IV: Dysplasia and Metaplasia
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
