A hematocele is a scrotal mass -- an abnormal growth in the scrotum. Scrotal masses can contain fluid, abnormal tissue, or normal scrotal contents that have become swollen. A hematocele causes sensitivity, redness, and swelling to the entire scrotal area. Testicle pain may be dull and aching. Since a hematocele can be cancerous, it is imperative to see a doctor promptly.
