Myxoid Liposarcoma of Spermatic Cord Misdiagnosed for Hemangioma

ABSTRACT

Myxoid liposarcoma arose from the spermatic cord is very rare. Also, it is difficult to diagnose by clinical findings or radiologic study. Even if it was a malignant tumor, scrotal malignancy is often misdiagnosed in many cases. A 55-year-old man presented with a mass in the left scrotum. Tumor markers showed all normal range. A scrotal magnetic resonance imaging scan revealed a vascular tumor such as a hemangioma. But, we performed radical orchiectomy. The mass was diagnosed as paratesticular myxoid liposarcoma. It is important to keep in mind the differential diagnosis of paratesticular liposarcoma in the case of a painless scrotal tumor.
