Sarcoma in the spermatic cord is rare, and accurate diagnosis of the histopathological subtypes are often difficult. A 62-year-old male smoker with a five-month history of left inguinoscrotal swelling was admitted to my hospital. Ultrasonography and computed tomography examinations showed a 4.0 cm×5.5 cm×4.5 cm solid mass engulfing the spermatic cord. The boundaries between the mass and the left testicle was distinct. Ultrasound-guided fine needle aspiration biopsy showed tumor originated from mesenchymal tissue, which is likely to be malignant, hence, enabling its removal by a left spermatic cord tumor resection via a left inguinal approach, under general anesthesia. The final pathological report showed an undifferentiated spermatic cord sarcoma. No recurrence and metastasis were observed in the patient during the subsequent 26 months follow-up period.

多原癌(multiple primary carcinoma,MPC)是指同一个患者的单一器官或多个器官同时或先后发生两个及以上彼此无关的原发恶性肿瘤,Moertel等 [1]认为多个恶性肿瘤发生间隔时间在6个月以内称为同时性多原癌,超过6个月称为异时性多原癌.本例报道1例同时性多原癌的诊疗经过.

多形性横纹肌肉瘤(pleomorphic rhabdomyosarcoma,PRMS)起源于未成熟横纹肌,其存在有向横纹肌分化的原始间叶细胞,儿童睾丸PRMS临床罕见且预后不良[J].组织学、免疫组化及超微结构对于诊断至关重要.本文报告1例初诊有转移征象的儿童睾丸PRMS.
