Nested variant of transitional cell carcinoma (NV-TCC) of the bladder is a rare and relatively new entity. The tumor is aggressive contrasted by its benign histopathologic appearance, and characterized by irregular urothelial nests and/or tubules. Herewith, a case with exceptional osseous metaplasia is presented emphasizing its diagnostic difficulties, because it can be confused with benign diseases or conventional TCC.
膀胱移行细胞癌巢状变异型（NV-TCC）是一种罕见且相对较新的实体。该肿瘤组织病理学表现为良性，却具有侵袭性，其特征为不规则的尿路上皮巢和/或小管。在此，我们报告一例伴有特殊骨化生的病例，强调其诊断困难，因为它可能与良性疾病或传统移行细胞癌相混淆。
