AbstractAbstract PDF
Von Hippel-Lindau (VHL) disease is an autosomal dominant neoplasia syndrome that result from a germline mutation in the VHL gene. Germline mutation in the VHL gene lead to the development of hemangioblastomas of the central nervous system and retina, cysts and clear cell carcinoma of the kidney, cyst adenomas of other organs, and pheochromocytoma. VHL is a tumor suppressor gene on the short arm of chromosome 3. VHL disease has been classified into two main clinical subtypes depending on the presence (type 2) or absence (type 1) of pheochromocytoma. Type 2 has been subdivided into three categories depending on the presence (type 2B) or absence (type 2A) of renal cell carcinoma, with type 2C being a rare subtype in which pheochromocytoma is the sole manifestation of VHL disease. Recently we experienced a family with VHL type 1 who carry C to T (Q73X) transition in codon 217 nonsense germline mutation in exon 1 of VHL gene. The authors report this case with literature review.

AbstractAbstract PDF
Von Hippel-Lindau (VHL) disease is an autosomal dominant disease, which forms hypervascular tumors in multiple organs, such as hemangioblastomas in the retina and central nervous system, renal cell carcinomas, pheochromocytomas and cysts in various organs. Recent advances in gene testing have made it possible to screen family members for VHL disease. We experienced a 28 year-old male, who was diagnosed with bilateral pheochromocytomas through a family screening test when his elder monozygous twin brother was diagnosed with a pheochromocytoma. He received no treatment until December, 2004, when he visited the Emergency room due to a headache. A hemangioma of the cerebellum was seen in the brain MR study, leading to the diagnosis of type 2A VHL disease. An abdominal CT scan revealed no lesions of the pancreas or kidney. There was no evidence of a hemangioma in the retinal scan. The subsequent gene testing showed a germline mutation in exon 3 codon 167 of the VHL gene. The mother of the patient was revealed to have the same mutation of the VHL gene, but the elder brother of the patient did not.

AbstractAbstract PDF
Multiple endocrine neoplasia (MEN) type 2A is a syndrome of medullary thyroid carcinomas, pheochromocytomas and parathyroid hyperplasia. The simultaneous occurrence of medullary, and papillary, thyroid carcinomas is rare because they are derived from, apparently, different germ layers, the former from the neuroectoderm and the latter from the endoderm. We report a case of a papillary thyroid carcinoma, combined with a medullary thyroid carcinoma, in a patient with MEN type 2A. Molecular genetic studies for screening a RET proto-oncogene mutation revealed a point mutation in codon 631 on chromosome 10, which is reported as highly uncommon in MEN type 2A.
