Ectopic intestinal varices are rarely responsible for lower gastrointestinal (GI) haemorrhage. A case of 55 years old male with recurrent melena is being presented, who was found to have scattered varices on small as well as large intestine. Selective review of literature regarding presentation, diagnosis and management of these cases is also part of presentation.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract, arising from incomplete obliteration of the vitelline duct. MD contains all layers of the intestinal wall and often remains asymptomatic. Gastrointestinal bleeding, bowel obstruction, and acute diverticulitis occur in a few cases.

Introduction: Endocrine paraneoplastic syndromes (ePNS) are caused by malignant cells that induce hormonal alterations unrelated to the tissue of origin of the neoplasm. The aim of this manuscript is to review the pathophysiology, diagnosis, and treatment of endocrine paraneoplastic syndromes (ePNS).
Areas Covered: We searched the PubMed/Medline, Embase, and Scielo databases, including 96 articles.

Background: Gastric mucosal heterotopia (GMH) is a rare, typically asymptomatic condition characterized by ectopic gastric mucosa in tissues outside the stomach. However, it can lead to severe complications, including small intestinal perforation. This case report highlights the unique clinical presentation of GMH-induced recurrent small intestinal perforations, which has been rarely documented.

Article Synopsis
- The small intestine's absorptive surface area is increased by structures called villi, which are influenced by stromal cells promoting bending through actomyosin contraction.
- Researchers induced contractility in intestinal mesenchyme, leading to villi that were shorter and wider than normal due to architectural defects, despite increased cell proliferation.
- The study highlights that contractility plays distinct roles in villus development and intestinal structure, separate from proliferation, and is dependent on interactions with the extracellular matrix.
