A 41-year-old man presented with a large abdominal tumor that yielded, in the fine needle aspiration biopsy, dyshesive, pleomorphic malignant cells. Electron microscopy of the aspirated material revealed nonepithelial cells showing intracytoplasmic bundles of microfilaments with vague focal densities and micropinocytotic vesicles along the cell membrane, suggesting a malignant leiomyosarcoma, which was confirmed by microscopic examination of the resected right kidney. The patient died four months after surgery from widespread metastases.
一名41岁男性因腹部有一巨大肿瘤就诊。细针穿刺活检显示有离散的、多形性恶性细胞。对穿刺物进行电子显微镜检查发现，非上皮细胞的胞质内有微丝束，沿细胞膜有模糊的局灶性致密区和微吞饮小泡，提示为恶性平滑肌肉瘤，切除的右肾显微镜检查证实了这一诊断。患者术后四个月因广泛转移而死亡。
