Adenocarcinoma Arising From Heterotopic Pancreas in the Duodenum

We present a rare case of adenocarcinoma arising from a heterotopic pancreas in the duodenum, and review the associated literature. A 62-year-old woman was admitted to our hospital, complaining of vomiting and epigastralgia. Imaging studies revealed advanced gastric cancer with a gastric outlet obstruction. Whipples operation and resection of the regional lymph node were performed because of a direct invasion to the pancreas. Histopathologic examination of the resected specimen demonstrated the malignant transformation of a hetrotopic pancreas in the duodenum. At the 12-month follow-up, there was no recurrence of symptoms. The prognosis of adenocarcinoma arising from a heterotopic pancreas is not known. Further accumulation of cases and investigation of this entity are necessary.

A rare case of xanthogranuloma of the stomach masquerading as an advanced stage tumor

BackgroundXanthogranuloma of the stomach is an extremely rare disease, and this lesion has only been found to coexist with early gastric cancer in 2 cases in the literature.Case presentationWe report a case of xanthogranuloma of the stomach combined with early gastric cancer that mimicked an advanced stage tumor. A 65-year-old female was referred to our hospital because of epigastralgia. During a physical examination, a defined abdominal mass was palpable in the region of the left hypochondrium. Imaging studies revealed an advanced gastric cancer, which was suspected of having infiltrated the abdominal wall. Total gastrectomy and resection of the regional lymph node and abdominal wall were performed. Histopathologic examination of the resected specimen demonstrated xanthogranuloma combined with early gastric cancer.ConclusionXanthogranuloma presenting as a form of SMT (submucosal tumor) of the stomach is an extremely rare disease, and diagnosing it preoperatively is difficult. Further accumulation and investigation of this entity is necessary.
