Massive primary lipoma of the scrotum.

Most lipomas occurring in the scrotum originate and develop in the spermatic cord. In rare cases, however, lipomas originate in the fat cells of the subcutaneous tissues of the scrotal walls themselves. These primary lipomas of the scrotum vary in size. We describe a patient with a scrotal mass that, to our knowledge, is the largest scrotal lipoma originating in the tunica dartos reported in the English literature.
