Liposarcoma of the spermatic cord: The state of art and our experience.

Liposarcoma of the spermatic cord is a malignant neoformation so rare that less than 200 cases are reported in the world. It is a tumor that originates from adipose tissue and when it is found in the spermatic cord it can deceptively simulate an inguinal hernia and not be easily identified. The present work describes the case of a 37-year-old man with liposarcoma of the spermatic cord who arrives at our institution with painless swelling of the left testicle. Physical examination revealed a painless swelling in the scrotal sac. The scrotal ultrasound examination revealed a mass, measuring 8 cm (cranio-caudal) × 5.4 cm (latero-lateral) × 8 cm (antero-posterior) and characterized later with a basal CT examination of the abdomen. The patient was subsequently surgically treated with excision of the tumor, plus hernial plastic with plug and mesh. Histological examination revealed a mature adipocyte neoplasm whose morphological and molecular characteristics (amplification of the MDM2 gene) are consistent with the diagnosis of . The patient is currently under cancer surveillance with no signs of loco-regional recurrence. Spermatic cord liposarcoma is an extremely rare malignancy. It's not easy to identify as it can simulate an inguinal hernia, hydrocele, lipoma, funicular cyst, or testicular tumor. Diagnosis is usually established postsurgery, however, relapses are common and the role of chemo-radiotherapy remains to be defined.
