Mixed adenoneuroendocrine carcinoma is a rare neoplasm with both epithelial and neuroendocrine components. To date, only a few cases of this neoplasm have been reported in the literature among which gastric mixed adenoneuroendocrine carcinoma is very rare. We are reporting a case of gastric mixed adenoneuroendocrine carcinoma with squamous cell differentiation. Histopathological features, biological behaviour and the treatment of this rare tumour type have been discussed briefly.

Introduction: Platynosomum fastosum is a dicrocoeliid fluke that infects birds and mammals, especially wild and domestic cats. Case report: A middle-aged male domestic cat was euthanized and examined. Its clinical features had included apathy, emaciation, hepatomegaly and mild jaundice on the mucosae. At necropsy, we noticed enlarged liver and dilated gallbladder. After opening the gallbladder lengthwise, multiple whitish flattened ellipsoidal structures were observed and identified as P. fastosum. The larger parasites were found in gallbladder, with significant different size from cystic duct and intrahepatic biliary ducts (p<0.05). Histopathological analysis revealed fluke-induced suppurative cholecystitis and chronic cholangitis. Precursor lesions of cholangiocarcinoma were reported. Conclusion: This report was part of the first prevalence survey of P.fastosum in municipality of Maracanaú, state of Ceará, northeastern Brazil.

Mixed adenoneuroendocrine carcinomas are rare tumors that contain both an exocrine and an endocrine component. Since the latest classification by the World Health Organization and with the aid of immunostaining, more mixed adenoneuroendocrine carcinomas are now identified and diagnosed. Nonetheless, our knowledge of these tumors is still limited, notably concerning gastric variants, as the cases reported in the literature are very limited. The clinical and surgical treatment, including the chemotherapy schemes, the prognosis, and recurrence still represent challenges for the medical teams. We present the case of a 62-year-old woman. After an upper endoscopy revealed multiple polyps and a low-grade neuroendocrine tumor, a D2 radical gastrectomy was performed. A low output esophageal anastomotic leak was discovered in the postoperative period and successfully managed. Pathology revealed a gastric mixed adenoneuroendocrine carcinoma, the first case of this kind reported in Ecuador. Patient is doing well and under constant surveillance up until her 13th postoperative month.
