Testicular yolk sac tumor

Testicular yolk sac tumor is more common in children and is a common germ cell malignant tumor in infants and young children. It is manifested by the enlargement of the testicles, the accumulation of hydrocele, and the rapid growth of the tumor. This tumor is very likely to develop into cancer. If it is not treated in time, it will develop into a late stage of cancer. Once the cancer cells spread and metastasize, amputation is required, otherwise it may be life-threatening. How should we deal with this symptom? Let's find out.

Yolk sac tumor, also known as infantile embryonal carcinoma, is a type of germ cell tumor and the most common testicular tumor in children under three years old.

These diseases have a very good prognosis, whereas carcinoma in situ found in adults is associated with other types of germ cell tumors, particularly teratomas, which are usually benign tumors, and embryonal carcinomas, which are malignant tumors.

The main performance is

1. Painless mass: Slowly growing, hard, painless scrotal mass. Older children may feel a sense of scrotal heaviness and pulling of the peritoneal groove. If the testicular tumor is torsion, the patient often complains of scrotal pain.

2. Symptoms of acute orchitis: Tumor bleeding and necrosis may cause symptoms of acute orchitis, such as sudden chills and high fever, nausea, vomiting and general discomfort. Local manifestations are testicular pain, mostly unilateral, sometimes severe pain, and radiating pain in the scrotum, thigh root and groin area. There may also be urinary tract infection, often with symptoms of frequent urination, urgency and pain. Physical examination shows swelling of the scrotum on the affected side, redness of the skin, increased temperature, and enlarged and tender testicles.

3. Scrotal effusion: Children with testicular malignancy may have scrotal effusion. The fluid in the testicular effusion is soft, elastic and cystic. The testicles and epididymis cannot be touched. The transillumination test is positive. When there is testicular effusion, there is a pear-shaped swelling in the scrotum and the testicles are also unclear. The initial symptoms of some children with testicular malignancy are compression symptoms of tumor metastasis, such as difficulty in urination and defecation caused by compression of abdominal lymph node metastasis.
