Hepatoid adenocarcinoma (HAC) is an uncommon and aggressive type of adenocarcinoma, typically affecting the middle-aged and elderly. The morphological features of the HAC resemble hepatocellular carcinoma. Presenting symptoms may include upper abdominal pain, hematemesis, back pain, and palpable abdominal mass. HAC has no proven therapy, and the prognosis is extremely poor. Early surgical removal with chemotherapy remains the standard of care. We describe one of the youngest patients in the literature with HAC who presented with acute pancreatitis. The diagnostic workup was confused by diffuse lymphadenopathy and elevated β-human chorionic gonadotropin making lymphoma and germ cell tumor likely possibilities until immunohistochemistry confirmed the diagnosis.
肝样腺癌(HAC)是一种罕见且侵袭性强的腺癌类型,通常影响中老年人。HAC的形态学特征类似于肝细胞癌。临床表现可能包括上腹部疼痛、呕血、背痛和可触及的腹部肿块。HAC尚无经证实有效的治疗方法,预后极差。早期手术切除并辅以化疗仍是标准的治疗方案。我们报道了文献中最年轻的HAC患者之一,该患者表现为急性胰腺炎。弥漫性淋巴结病和β-人绒毛膜促性腺激素升高使诊断检查结果混淆,在免疫组化确诊之前,淋巴瘤和生殖细胞肿瘤是可能的诊断。
