Background:
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.
Clinical Case:
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.
Conclusions:
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.
