Rhabdomyosarcoma of the urinary bladder in adults is exceedingly rare. Reported cases have been of the embryonal botryoid type, as seen in children. We will describe a case of pleomorphic rhabdomyosarcoma occurring in the urinary bladder of an adult. In this case, we noted striking intraepidermal migration of tumor cells, resembling the epidermotropic growth characteristic of tumor cells in Paget disease of the breast. The pathological features of this apparently unique case form the subject of this report.
成人膀胱横纹肌肉瘤极为罕见。已报道的病例均为胚胎型葡萄状肉瘤,与儿童所见相同。我们将描述一例发生于成人膀胱的多形性横纹肌肉瘤。在该病例中,我们注意到肿瘤细胞显著的表皮内迁移,类似于乳腺佩吉特病中肿瘤细胞的亲表皮生长特征。这一明显独特病例的病理特征构成了本报告的主题。
