OBJECTIVE: We report two cases of patients diagnosed of paratesticular liposarcoma and perform a literature review of this rare entity. Our aim is to clarify its clinical and therapeutic characteristics.

METHODS: Retrospective review of the medical records of two patients diagnosed of liposarcoma of the spermatic cord.

RESULTS: Case 1: 65 year old male, presented a left large scrotal mass of 20 x 14 x 11 cm. He underwent radical orchiectomy. Pathology reported a well differentiated spermatic cord liposarcoma. After one year of follow-up the patient was asymptomatic and there was no evidence of local recurrence. Case 2: A 90 year old man, with past medical history of right orchiectomy for well-differentiated cord liposarcoma 11 years before, and excision of recurrence 7 years ago. On follow up he presented a new 20 x 14 x 11 cm inguinal tumor recurrence. We performed excision of the mass, which was reported by pathology as well differentiated spermatic cord liposarcoma. Ten months after surgery the patient was asymptomatic without recurrence.

CONCLUSIONS: Liposarcoma is a very rare entity and its diagnosis is based on the pathological findings. It is therefore difficult to establish the guidelines for treatment, prognosis and differential diagnosis. As in liposarcomas in other sites, the histological type and grade of the lesion are useful for the prognosis. Radical inguinal orchiectomy and resection of the tumor with a negative microscopic margin is the recommended treatment for liposarcoma of the spermatic cord. It has not been demonstrated the efficacy of adjuvant treatments such as chemotherapy or radiotherapy, except in specific situations. The natural history of disease is slow and it has low mortality, but high recurrence rate, so a long-term monitoring is necessary.
