Osteoclast-rich undifferentiated carcinoma (ORUC) of the urinary tract is a rare variant of urothelial carcinoma, first described in 1985 by Kitazawa et al. It has a worse prognosis compared to other histological variants of invasive urothelial carcinoma and its diagnosis may prove challenging due to the variability in its immunohistochemical profile. We present a case of ORUC in which GATA3 immunostaining was a useful diagnostic tool.
富含破骨细胞的未分化癌(ORUC)是尿路上皮癌的一种罕见变异型,于 1985 年由 Kitazawa 等人首次描述。与其他浸润性尿路上皮癌的组织学变异型相比,它的预后更差,由于其免疫组织化学特征的可变性,其诊断可能具有挑战性。我们报告了一例 GATA3 免疫染色有助于诊断的 ORUC 病例。
