Spermatic cord liposarcoma presented as scrotal swelling: a case report

Abstract

Liposarcoma is considered the most common among spermatic cord sarcomas. It usually presents as a progressively enlarging inguinoscrotal mass. The resemblance between the spermatic cord liposarcoma and the inguinal hernia allows the swelling to be tolerated for a long duration giving time for hematogenous dissemination. In this article, we share the experience of a unique case of metastatic liposarcoma of the spermatic cord that showed a stationary course of the lower abdominal satellite lesions on follow-up following palliative resection. We present a case of a 53-year-old male with progressively enlarging painless scrotal swelling over 1-year duration. A heterogeneous lesion of the right hemiscrotum and spermatic cord with non-specific radiological features was described by imaging. Two lower abdominal skip lesions were also discovered synchronously in addition to the primary one and were designated inoperable as they were adherent to the nearby bowel loops. The patient underwent cytoreductive surgery of the primary tumour which was proven to be an undifferentiated liposarcoma with free safety margins based on histopathology. Finally, the patient was referred for adjuvant chemotherapy and sequential follow-up. Despite being a rare tumour, the radiologist should always consider the liposarcoma of the spermatic cord in the differential diagnosis of inguinoscrotal lesions even in the absence of typical imaging features. The diagnosis and management of spermatic cord liposarcoma remain a challenge with no clear accepted guidelines.
