Cytogenetic characterization of renal cell carcinoma in von Hippel‐Lindau syndrome

We report the case of a 26‐year‐old man with von Hippel‐Lindau syndrome (VHL) and two renal cell carcinomas (RCC), one of which was studied cytogenetically. Chromosomal analysis of the RCC showed a translocation that involved chromosomes 3 and 8 with subsequent loss of the derivative chromosome 8. T...

Description
Summary:We report the case of a 26‐year‐old man with von Hippel‐Lindau syndrome (VHL) and two renal cell carcinomas (RCC), one of which was studied cytogenetically. Chromosomal analysis of the RCC showed a translocation that involved chromosomes 3 and 8 with subsequent loss of the derivative chromosome 8. The patient's peripheral lymphocytes showed a normal karyotype that indicated that there was not a constitutional chromosomal translocation. This is the third reported case of RCC in a patient with VHL in which loss of a portion of the short arm of chromosome 3 (3p) has occurred. Similar chromosomal changes that involve 3p have been reported in both familial and sporadic cases of RCC and have led to speculation that a tumor suppressor gene may be located in this region. Cytogenetic characterization of renal tumors could assume increasing significance in the diagnosis and classification of RCC and potentially may guide therapy. These studies may also lead to a better understanding of the biologic behavior of RCC and result in more informed patient evaluation and counseling.
