Vascular myxolipoma ("angiomyxolipoma") of the spermatic cord.

Abstract

We report a case of vascular myxolipoma of the spermatic cord occurring in a 32-year-old man. Clinically, the lesion was mobile and tender. Pathologically, the tumor was encapsulated and rubbery with a beige-yellow gelatinous cut surface. Microscopically, the lesion consisted of adipose tissue with extensive areas of myxoid change and an abundance of thin and thick-walled blood vessels. We consider this tumor a vascular type of myxolipoma and propose the term angiomyxolipoma. The lesion should be distinguished from liposarcoma and aggressive angiomyxoma, which have malignant or aggressive clinical course.
