Leiomyosarcoma of the Spermatic Cord in a Seventy-Five-Year-Old man

INTRODUCTION: Leiomyosarcoma is a malignant soft tissue tumor that can arise from any tissue containing smooth muscle. Leiomyosarcomas of the spermatic cord are rare tumors of non-testicular origin, which drain into the retroperitoneal lymph nodes and have been reported in less than 150 cases in the literature until now. Radical inguinal orchiectomy and high ligation of the cord is the standard primary surgical procedure in spermatic cord leiomyosarcoma. CASE PRESENTATION: Here we reported a 75-year-old man who presented with a painless lump in the right hemiscrotum. A right radical orchiectomy was performed. Histopathology confirmed a neoplastic tissue with mesenchymal origin in spermatic cord; further evaluation revealed a leiomyosarcoma of the spermatic cord. The patient was followed up for 1-year and shows no signs of recurrence CONCLUSIONS: Preoperative diagnosis of spermatic cord leiomyosarcma is difficult and commonly made by histological examination and immunochemical staining.
