A Giant Gastric Lipoma

Case Report: We present a clinical case of a woman, 59 years old, with a history of papillary thyroid carcinoma with cervical metastases, asymptomatic. During the follow-up of the carcinoma, a large lipomatous formation was detected in the lesser curvature of the stomach, well circumscribed, in the submucosa. A complementary study was carried out with upper digestive endoscopy (UDE) and ecoendoscopy. The UDE confirmed a lesion on the lesser curvature, covered by normal mucosa, raising suspicion of a gastrointestinal stromal tumor (GIST) or lipoma. However, the biopsy of the lesion did not reveal signs of malignancy. The patient was then proposed for surgery. The patient underwent laparoscopic surgery for extramucosal enucleation of a gastric lipoma measuring 8.5 cm, with resection of the adherent mucosa. The postoperative period was uneventful, with discharge on the 5th day. The anatomopathological examination revealed that it was a well-differentiated lipomatous tumor, negative for the MDM2 gene.
