Well-differentiated liposarcoma of the spermatic cord: A case report

A 51-year-old man visited our hospital for voluntary cancer screening. Positron emission tomography and computed tomography (PET-CT) incidentally found a mass in the left scrotum. The patient was referred to our department. Magnetic resonance imaging suggested a diagnosis of a fat-containing tumor of the spermatic cord and excluded an inguinal hernia. High orchiectomy was performed due to a diagnosis of lipoma or liposarcoma. Histopathological diagnosis was well-differentiated liposarcoma. He has survived 28 months after surgery without recurrence. Spermatic cord tumors are difficult to diagnose with imaging, and attention must be paid to the possibility of malignant tumors.
