the scrotum Redness of the skin of the scrotum Nausea or vomiting If the cause of the scrotal mass is due to infection then signs and symptoms may be the following: Pus Pus or blood in the urine Fever Cause Scrotal masses might be an accumulation of fluids, the growth of abnormal tissue, or normal contents of the scrotum that have become swollen, inflamed or hardened. Scrotal masses could be cancerous or caused by another condition that affects testicular function and health. A hematocele is one of the most common sequelae of testicular trauma. A traumatic hematocele usually results from testicular rupture (80% of cases) or a tear in the pampiniform plexus veins. Testicular rupture and testicular torsion are also common causes of scrotal hematocele. It can also be caused by kidney injury, pancreatitis, hematological dysfunction, or vasculitis. There are different disorders that can result as a consequence or a hematocele which include: Testicular cancer Spermatocele Epididymitis Orchitis Hydrocele Variocele Inguinal hernia Testicular torsion Pathophysiology Chronic hematocele is rare. The direct cause of hematoceles is still unknown. Hematoceles can be classified into idiopathic and secondary ones. Idiopathic or spontaneous hematoceles give no history of testicular cancer or past trauma to testis, no pain in the organ, and seems to be more common the older population. Secondary hematoceles are usually associated with trauma, surgery, or neoplasm, but can also be caused by hematological alterations, or vasculitis. Presumably minor trauma results in rupture of dilated microvessels beneath the fibrous capsule. Hematoceles present as slowly progressing. The duration of swellings of hematoceles can last months to decades. Usually there is no pain, but discomfort and heavyness is most common in the scrotum. In hematocele of recent occurrence the tunica sac contains coagulated fresh blood. A hematocele that begins bleeding into itself, becoming a hemorrhagic cyst, can easily rupture and cause a number of problems. If the hematocele is older, the tunica sac appears filled with spongy material several times larger than the testicular volume. Most of this material is fibrin and cholesterol granulomas . In chronic hematocele the blood clot is totally or partially consisting of connective tissue that contains numerous newly formed blood vessels and hemosiderin-laden macrophages. Connective tissue facing the tunica cavity is lined by fibrin remnants. In its final stages the lesion consists of a thickened, fibrosed, and calcified tunica sac which may also show osseous metaplasia. Diagnosis Hematoceles can
