Abstract

Background: Laparoscopic sleeve gastrectomy (LSG) progressively became the preferred procedure worldwide for the treatment of morbid obesity. Occasionally, unknown gastrointestinal diseases may be incidentally discovered during the procedure or on the histologic gastric specimen. Gastric xanthomas are uncommon lesions of the lamina propria, composed by foamy macrophages and mixed inflammatory infiltrate. Rarely, xanthoma cells develop within a gastric hyperplastic polyp. Although usually benign, they may be associated with pre-malignant conditions or even gastric cancer, making advisable an appropriate workup. Case Presentation: A hyperplastic polyp with xanthomatous proliferation was discovered in the gastric specimen of a young man, suffering from severe obesity and metabolic syndrome. The patient had been treated with proton pump inhibitors for gastric discomfort for years. After the surgical procedure, the gastric discomfort rapidly disappeared. Conclusion: Obesity is often complicated by gastrointestinal abnormalities discovered during ultrasound or endoscopic procedures. Incidental findings of unknown gastric lesions are common occurrences during sleeve gastrectomy. Although xanthelasmas per se are harmless, they might coexist with pre-malignant/ malignant lesions, especially when associated with gastric polyps. Thus, prompt intra-operative recognition and adequate work-up are mandatory. Although cases of gastric polyps or xanthomas are not a novelty, to our knowledge, this is the first case reporting about the discovery of a gastric hyperplastic polyp with xanthomatous proliferation on gastric histological piece. From the discussion of this case and of similar reports in the literature, we advocated for the importance of endoscopic screening in obese patients admitted for bariatric surgery to address the proper surgical approach and follow-up
