Benign Tumours of the Small Bowel
(2025) p.521-544- Abstract
Benign tumours of the small intestine consist of various rare entities such as tumour-like inflammatory or hyperplastic lesions, hamartomas (organoid malformations), ectopic tissues, and true neoplasms of epithelial or mesenchymal origin. These benign tumours often stay asymptomatic for years, with small lesions frequently remaining undiscovered. They may be manifested clinically by bleeding, iron deficiency anaemia, or abdominal pain. Possible complications are obstruction, intussusception, and perforation. These symptoms depend on the tumour’s size, location, and histopathology. Adenomas may progress to carcinoma. Hyperplasias, hamartomas, ectopic gastric mucosa, and adenomas may appear as flat or raised lesions on the mucosal... (More)
Benign tumours of the small intestine consist of various rare entities such as tumour-like inflammatory or hyperplastic lesions, hamartomas (organoid malformations), ectopic tissues, and true neoplasms of epithelial or mesenchymal origin. These benign tumours often stay asymptomatic for years, with small lesions frequently remaining undiscovered. They may be manifested clinically by bleeding, iron deficiency anaemia, or abdominal pain. Possible complications are obstruction, intussusception, and perforation. These symptoms depend on the tumour’s size, location, and histopathology. Adenomas may progress to carcinoma. Hyperplasias, hamartomas, ectopic gastric mucosa, and adenomas may appear as flat or raised lesions on the mucosal surface. Ectopic pancreatic tissue and mesenchymal tumours usually are located beneath normal mucosa, have smooth margins, and are raised. The surface may show a generally circumscribed ulceration, which can cause bleeding. Vascular tumours often have a reddish or bluish appearance. Endoscopic examination cannot reliably differentiate between benign and malignant tumours of the small intestine. Examples for different benign small bowel tumours are presented.
