Leiomyosarcoma of the spermatic cord

Abstract

Leiomyosarcoma of spermatic cord is very rare. The patient is 65-year-old man who presented with a tumor in scrotum. Excision of tumor was performed and it showed a solid tumor measuring 4 cm × 3 cm × 3 cm in left spermatic cord. Histologically, it showed proliferation of hypercellular atypical spindle cells with hyperchromatic nuclei. The tumor cells were arranged with fascicles of cigar-shaped spindled cells with scant acidophilic cytoplasm. The tumor was not encapsulated, and mild invasive features into surrounding tissue were noted. The mitotic index was 17; 17 mitotic figures were seen in 10 high-power-fields. Atypical mitosis was also seen. Immunohistochemically, tumor cells were positive for vimentin, α-smooth muscle actin, hcaldesmon, desmin (focal), p53, and Ki-67 (labeling index = 34%). No other tumors were identified in the body, and the patient further treated with auxiliary local radiation and chemotherapy (cisplatin and doxorubicin). He is now healthy and free from tumors in the body 15 months after the operation.
