Giant paratesticular liposarcoma: A rare case report and literature review

Paratesticular liposarcoma is a rare variant of genitourinary malignancy. This malignancy accounts for less than 12 % of all liposarcomas. Approximately 200 cases of paratesticular liposarcoma have been reported. Giant paratesticular liposarcoma sizing over 10 cm is rarer, with only a few reported cases. Due to the rarity of this disease, there are no standardized guidelines regarding its incidence, diagnostic, recurrence, and treatment.

A 73-year-old male came to the hospital with a painless left scrotal mass three years ago. The patient had an ultrasound examination of the left scrotal, which proved a solid mass and hypervascular on the left testicular. Abdominopelvic computed tomography (CT) showed a solid-cyst masses, size ±16,6 × 9,6 × 18,2 cm, lobulated, contrast enhancement with no sign of metastatic disease. The patient had radical orchiectomy without any complications. Histopathological and immunohistochemistry examination (Vimentin, MDM2, dan CDK4) showed well-differentiated liposarcoma.

Radical orchiectomy is the best curative therapy. Adjuvant chemotherapy and radiotherapy benefit is still inconclusive. The patient had followed up for two years after surgery found no recurrent mass and metastatic. The well-differentiated type has a better prognosis but has a high incidence of local recurrence if incompletely excised. The result showed that this approach produces excellent outcomes without any relapse.

Giant Paratesticular Liposarcoma is a rare condition that can be managed by radical. Long-term follow-up is importance to observe the relapse of this malignancy.
