Trisomy 5 and trisomy 7 are nonrandom aberrations in pigmented villonodular synovitis: Confirmation of trisomy 7 in uncultured cells
1 Apr 1992
Abstract excerpt
Pigmented villonodular synovitis (PVNS) is a proliferative lesion of disputed genesis. Recently, we reported trisomy 7 in short-term cultures of 1 PVNS. In the present report, we describe another specimen of PVNS in which 9 of 26 (35 percent) metaphase cells demonstrated trisomy 7 when analyzed after 3-15 days of tissue culture. In situ hybridization analysis, with a biotinylated probe to chromosome 7...
