title: Association of trisomy 8 and squamous differentiation in an endometrial adenocarcinoma.
abstract: Cytogenetic analysis was performed on a case of endometrial adenocarcinoma in which 10% to 15% of the tumor showed squamous differentiation. Of 26 cells examined, all had trisomy 1q and monosomy 16; four cells (15%) also showed trisomy 8. Trisomy 8 is an unusual finding in endometrial carcinoma, having been reported in only one other case, which was an adenosquamous carcinoma. Our findings suggest that trisomy 8 may be a marker of squamous differentiation in endometrial carcinoma.
