[Metastatic renal cell carcinoma: a clinicopathological analysis of 196 cases].
Objective: To analyze the clinico pathological features, differential diagnosis and prognosis of metastatic renal cell carcinomas. Methods: The clinical data, histology, immunophenotype and follow-up data of 196 patients with metastatic renal cell carcinoma diagnosed from 1994 to 2017 at the Department of Pathology, Changhai Hospital, Naval Military Medical University, Shanghai, China were analyzed retrospectively. Results: There were 142 males and 54 females, with a median age of 61 years. ⋯ Five years after primary lesion resection may be the high risk time for metastasis. Most of the metastases are solitary when they are first identified. To better diagnose and identify the renal origin of a metastatic renal cell carcinoma, one should consider morphological characteristics, clinical history information of the metastasis and the combined immunohistochemistry of CK, vimentin, CD10, CK7, TFE3, PAX2 and PAX8.
