Well-differentiated liposarcoma of spermatic cord presenting as recurrent inguinal hernia: a case report

Well-differentiated liposarcoma arising from the paratesticular region is rare, with only a few hundred cases reported in the literature. Due to their unexpected location, these tumors are often confused for common pathologies found in the groin, including inguinal hernia, seroma, or lymphoma. Standardized diagnostic and treatment pathways have not been established for patients with paratesticular liposarcoma, thereby elevating the importance of sharing our experience.

This case describes the presentation of a 65-year-old man with a well-differentiated liposarcoma of the spermatic cord. Diagnosis was made after he underwent open herniorrhaphy to repair what was presumed to be a recurrent left inguinal hernia. Although a recommendation for formal oncologic resection and orchiectomy was made, the patient elected to proceed with watchful waiting and remains well up to last known contact.

Paratesticular liposarcoma remains a rare clinical entity. While a few hundred cases have been reported in the literature, only a handful describe its presentation masked as an early recurrence of a groin hernia. Wide local resection along with orchiectomy and potential radiation therapy have been the mainstay of treatment. Clinicians should maintain a healthy level of suspicion for this uncommon pathology, especially in cases where patients present with early recurrence of an inguinal hernia.
