Small cell neuroendocrine carcinoma of the ampulla of Vater is extremely rare and different from the common ampullary adenocarcinoma. The ampullary adenoma is also a rare neoplasm and has the potential to develop an adenocarcinoma. Their coexistence has been rarely reported in the literature. We herein describe an unusual case of a small cell neuroendocrine carcinoma associated with a villous adenoma in the ampulla of Vater with emphasis on computed tomography (CT) and histopathological findings. We also discuss their clinical, histopathological and radiological features as well as possible histogenesis.
壶腹小细胞神经内分泌癌极为罕见,与常见的壶腹腺癌不同。壶腹腺瘤也是一种罕见的肿瘤,有发展为腺癌的可能。它们的共存情况在文献中鲜有报道。我们在此描述一例罕见的壶腹小细胞神经内分泌癌合并绒毛状腺瘤的病例,重点介绍计算机断层扫描(CT)和组织病理学检查结果。我们还将讨论它们的临床、组织病理学和放射学特征以及可能的组织发生学。
