Paratesticular liposarcomas are rare tumors which account for 12% of all liposarcomas. They must be differentiated from tumors of testicular origin which have extension to the spermatic cord.
We reported a case of a 72-year-old male who had presented with a painless swelling mass in the left hemiscrotum, which was of 10 years' duration. Initially, a clinical impression of scrotal tumor was made; however, CT of the scrotum revealed a spermatic cord mass. The mass was managed by excisional biopsy and later pathology reported dedifferentiated liposarcoma with margin involvement. Metastatic work-up, which included CT of the abdomen and pelvis and chest X ray, did not reveal any distant metastasis. Patient underwent high orchidectomy with skin excision. Histopathological studies confirmed the diagnosis of dedifferentiated liposarcoma with clear surgical margin.
Liposarcomas of the spermatic cord represent a rare type of tumors, which are often misdiagnosed preoperatively. Being a rare disease and varied type of presentation, paratesticular liposarcoma should be considered as a possibility during the differential diagnosis of fat containing inguino-scrotal mass.
