Endocrine manifestations of von Hippel-Lindau disease.

VHL的内分泌表现

Abstract

von Hippel-Lindau (VHL) disease is an autosomal dominant disorder caused by heterozygous mutations in the VHL tumor suppressor gene that is characterized by the occurrence of multiple endocrine and nonendocrine lesions. This review focuses on the endocrine manifestations of VHL disease. Pancreatic neuroendocrine proliferations (ductuloinsular complexes, islet dysplasia, endocrine microadenoma, and neuroendocrine tumors), pheochromocytomas, and extra-adrenal paragangliomas are important endocrine manifestations of VHL disease. They frequently display characteristic clinical, biochemical, and histopathologic features that, although not pathognomonic, can be helpful in suggesting VHL disease as the underlying etiology and distinguishing these tumors from sporadic cases. Recent improvements in treatment and outcomes of renal cell carcinomas have allowed pancreatic neuroendocrine tumors to emerge as a significant source of metastatic disease, making the accurate recognition and classification of these neoplasms by the pathologist of utmost importance to determine prognosis, treatment, and follow-up strategies for affected patients.

摘要

von Hippel-Lindau(VHL)疾病是由VHL肿瘤抑制基因杂合突变引起的常染色体显性遗传疾病,特征是具有多个内分泌和非内分泌病变。这篇文章重点讨论VHL病的内分泌表现,包括胰腺神经内分泌增生(导管胰岛增生,胰岛发育不良,内分泌微腺瘤和神经内分泌肿瘤)、嗜铬细胞瘤和肾上腺外副神经节瘤等。这些病变经常表现出特征性的临床、生化和组织病理学特点。这些特点虽然没有病理确诊性,但是可能有助于提示潜在的VHL疾病,也可能有助于将VHL和散发病例区分开来。由于肾细胞癌治疗和预后的进展,胰腺神经内分泌肿瘤已是肾脏转移癌的重要来源。因此,对胰腺神经内分泌肿瘤的鉴别和分类对于确定VHL病人的预后、治疗以及随访至关重要。
