Paratesticular Liposarcoma: What is the Best Therapeutic Strategy?

Abstract

Introduction: Liposarcomas are neoplasms of mesodermal origin derived from adipose tissue and correspond to 10–14% of all soft tissue sarcomas. Paratesticular liposarcoma is very rare.
Case report: We report a 60-year old man who presented with a left testicular tumor 20 cm in diameter. Initial incisional biopsy was reported as fibromatosis. Chest and abdominal CT scan did not show distant metastases. Through an inguinal incision orchidectomy with homolateral inguinal node dissection was performed. Histopathological examination showed a paratesticular myxoid liposarcoma. Adjuvant radiotherapy without chemotherapy was administered. The patient remains well at 11 months followup, with no evidence of recurrence.
Conclusion: Complete surgical extirpation reduces the risk of local recurrence. Neoadjuvant chemotherapy or radiotherapy may reduce the tumor size, thus facilitating complete excision.
