Mitochondrial Iron Accumulation in Parietal and Chief Cells in Iron Pill Gastritis Following Billroth II Gastrectomy: Case Report Including Electron Microscopic Examination.

Iron pill gastritis has been shown to be associated with superficial gastric erosion and deposition of iron in lamina propria and gastric antral glands. However, iron absorption in gastric parietal and chief cells is rare. We present a case of a 62-year-old man with iron deficiency anemia.

Utility of desmin and a Masson's trichrome method to detect early acute myocardial infarction in autopsy tissues.

Detection of early acute myocardial ischemia/infarction prior to neutrophilic infiltration in autopsy myocardium poses a diagnostic dilemma to the surgical pathologist. Morphological changes can be subtle or not identified at all on the hematoxylin and eosin stain. To evaluate the Masson's trichrome stain and immunohistochemical stains, desmin and myoglobin, in detecting acute myocardial ischemia/infarction in autopsy myocardium.

Castleman's disease in the head of the pancreas: report of a rare clinical entity and current perspective on diagnosis, treatment, and outcome.

Background: Castleman's disease of the pancreas is a very rare condition that may resemble more common disease entities as well as pancreatic cancer.

Case Presentation: Here we report the case of a 58-year-old African American male with an incidentally discovered lesion in the head of the pancreas. The specimen from his pancreaticoduodectomy contained a protuberant, encapsulated mass, exhibiting microscopic features most consistent with localized/unicentric Castleman's disease.

Adenocarcinoma arising within a colonic diverticulum: report of two cases and review of the literature.

The first reported cases of colonic carcinoma arising within a diverticulum are documented. Although colonic diverticulitis and cancer are common diseases in patients over 60 years of age, cancer arising within a diverticulum is rare. Only close histopathologic scrutiny can differentiate inflammatory changes from neoplasia.
