Thyroid-like follicular carcinoma of the kidney (TLFCK) is a rare subtype of renal cell carcinoma, which closely resembles follicular neoplasms of the thyroid and has a distinctive indolent clinical behavior. Until now, a single case of TLFCK with extensive sarcomatoid differentiation has been documented with aggressive clinical course. We present an unusual case of sarcomatoid TLFCK with a low-grade spindle cell component in a 34-year-old male patient, with an indolent course following radical nephrectomy and regional node dissection.
肾甲状腺样滤泡癌（TLFCK）是一种罕见的肾细胞癌亚型，与甲状腺滤泡性肿瘤非常相似，具有独特的惰性临床行为。到目前为止，仅有一例伴有广泛肉瘤样分化的 TLFCK 病例被记录，其具有侵袭性的临床病程。我们报告了一例罕见的 34 岁男性患者的梭形细胞低级别成分的肉瘤样 TLFCK 病例，在根治性肾切除术和区域淋巴结清扫术后，病程呈惰性。
