Symptoms of testicular teratoma in infants?

summary

Testicular teratomas in infants are benign lesions. 22% - 37% of the patients with testicular teratomas after puberty have metastasis. Dermoid cyst is a special type of benign monoblastic teratoma. Under the microscope, it is characterized by a cyst rich in hair and keratin, accompanied by skin appendages. Testicular teratomas are mostly composed of two or more kinds of endoderm, including mucous glands in endoderm, cartilage, bone, muscle and lymph tissue in mesoderm, and squamous epithelium and nerve tissue in ectoderm. Symptoms of testicular teratoma in infants? Let's talk about it.

Symptoms of testicular teratoma in infants?

The high incidence age of testicular teratoma can be divided into children and adults. The high incidence age of testicular teratoma in children is 1-2 years old, and that in adults is 25-35 years old. Most of the patients showed painless testicular mass, which was hard, nodular or irregular.

Ultrasonography is the first choice for clinical diagnosis of testicular lesions. B-ultrasound has important clinical value in judging the nature, size, location of testicular tumor, the proportion of tumor in testicular tissue, and even the choice of treatment. Testicular teratoma showed clear boundary, cystic solid, cartilage, immature bone tissue or calcification.

The level of serum alpha fetoprotein (AFP) in adult patients with testicular teratoma is correlated with benign and malignant. The level of AFP in children with testicular teratoma is in the normal range with the corresponding age group, but there is a big difference in the level of AFP in normal infants within 6 months. Therefore, there is no clear clinical significance for the level of AFP in infants within 6 months.

matters needing attention

Patients with testicular dermoid cyst and testicular teratoma in children need no other treatment after operation. Radical orchiectomy and retroperitoneal lymph node dissection were performed in the patients with testicular teratoma and retroperitoneal lymph node metastasis after puberty. The pathological types of most metastatic teratomas were the same as those of primary teratomas, but some of them had embryonal carcinoma. The malignant component of distant metastatic teratoma is not effective in the chemotherapy of germ cell tumor.
