Osseous metaplasia of the stroma of carcinomas of the bladder is a rare finding that must be distinguished from osteosarcoma and carcinosarcoma. We report a case of multifocal osseous metaplasia in a high grade urothelial carcinoma with extensive glandular differentiation, arising in the base of the bladder of an 84-year-old man. Reports of 11 other cases of stromal osseous metaplasia in primary bladder carcinomas and of 5 cases of stromal osseous metaplasia in metastases of bladder carcinoma are reviewed.
膀胱癌基质的骨化生是一种罕见的发现，必须与骨肉瘤和癌肉瘤相鉴别。我们报告一例发生于一名84岁男性膀胱底部的高级别尿路上皮癌伴广泛腺性分化的多灶性骨化生病例。本文还回顾了原发性膀胱癌基质骨化生的其他11例报告以及膀胱癌转移灶中基质骨化生的5例报告。
