Abstract:
Gastrointestinal leiomyosarcomas are rare malignancies. Herein, we present a case report of a previously healthy 60-year-old female presenting with periumbilical abdominal pain, vomiting, and difficulty in passing stool, with clinical workup, imaging, and surgery defining a small intestine tumor. Histology defined the tumor as a mesenteric pleomorphic leiomyosarcoma.

01:26Histology of the Large Intestine
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
