title: Trisomy 12 and 4 in a thecoma of the ovary.
abstract: Cytogenetic analysis of short-term tissue culture from a thecoma of the ovary demonstrated the presence of trisomies of chromosomes 12 and 4 in all analyzed cells. Our finding confirms the consistency with which trisomy 12 is observed in benign sex cord/stromal tumors and suggests that trisomy 4 may be a second event in tumorigenesis of thecoma.
