RESUMO
We introduce the case of a 40-year-old male with no medical history of interest who was admitted in the Digestive System unit due to upper gastrointestinal bleeding, and a large protruding lesion located in gastric antrum was detected during oral endoscopy, but biopsies were negative for malignancy. Therefore, endoscopic ultrasound was performed, confirming the submucosal origin of the lesion, puncturing it, and obtaining histological results compatible with leiomyoma. Gastric leiomyomas are rare mesenchymal tumors that are usually asymptomatic and are detected by performing a procedure for another reason. The definitive diagnosis is histological, being sometimes difficult to obtain samples given the submucosal origin of these lesions. The main treatment is surgery, although endoscopic resection is accepted in certain cases.

A 46-year-old man underwent colonoscopy due to familiar screening for colorectal cancer, revealing an 8-mm rounded lesion in the middle rectum, subepithelial in appearance, with non-specific characteristics. Biopsies were taken, which were inconclusive. The study was completed with a CT scan, which was normal. Given the characteristics of the lesion, smaller than one centimetre, with a low probability of muscle invasion and the possibility of complete resection, band-assisted endoscopic treatment was decided, without first carrying out an endosonographic study.

An 82-year-old female with a history of osteoporosis and achalasia treated with periodic botulinum toxin injections presented a few weeks after the last session, reporting dysphagia and retrosternal pain. An upper gastrointestinal endoscopy revealed mucosal involvement in the middle and lower third of the esophagus in the form of edema, friability, exudate and extensive superficial ulcers, which converged distally and extended around the entire circumference. The cardia was punctiform, but could be passed without difficulty.
