Biphasic squamoid alveolar renal cell carcinoma (BSARCC) is a newly emerging distinct and rare morphologic variant of renal cell carcinoma (RCC). Morphological, immunohistochemical, and molecular data have shown that BSARCC is closely related to papillary RCC type 1. We report a case of Biphasic squamoid alveolar renal cell carcinoma with a rare presentation as cutaneous metastases. This variant tends to show an aggressive behavior. Hence, accurate histopathological diagnosis can help in effective treatment and for close follow-up of the patients.
双相鳞状肺泡样肾细胞癌（BSARCC）是一种新出现的、独特且罕见的肾细胞癌（RCC）形态学变异类型。形态学、免疫组织化学及分子学数据表明，BSARCC与1型乳头状RCC密切相关。我们报告1例双相鳞状肺泡样肾细胞癌，其表现为罕见的皮肤转移。该变异型往往表现出侵袭性生物学行为。因此，准确的组织病理学诊断有助于有效治疗及对患者进行密切随访。
