Urothelial carcinoma of urinary bladder with divergent differentiation into rhabdomyosarcoma (RMS) is an extremely uncommon aggressive phenomenon. We present a case of a 74-year-old male with bladder carcinoma which metastasized to the abdominal wall as epithelioid RMS. To the best knowledge of our literature searches, an oligometastasis of exclusive heterologous component has not been described before. The clinical, radiological, and immunohistochemistry profile of the patient supported the monoclonal nature of the tumor.
膀胱尿路上皮癌伴异向分化为横纹肌肉瘤（RMS）是一种极其罕见的侵袭性现象。我们报告一例74岁男性膀胱癌患者，该肿瘤转移至腹壁，表现为上皮样RMS。就我们文献检索所知，此前尚未描述过仅含异源成分的寡转移情况。该患者的临床、影像学和免疫组化特征支持肿瘤的单克隆性质。
