The majority of patients with teratoma are asymptomatic. The signs and symptoms depends on the tumor locations such as genitals, mediastinum,and sacrococcygeal areas. The most common symptoms include abdominal pain, swelling, mass, cough, dyspnea, abnormal uterine bleeding.

History and Symptoms

  • The majority of patients with teratoma are asymptomatic Less commonly, the newborn may exhibit only asymmetry of the buttocks or present when aged 1 month to 4 years with a presacral tumor that may extend into the pelvis. The latter group is at higher risk for malignancy. Ovarian teratoma: Mature cystic teratomas of the ovary often are discovered as incidental findings on physical examination, during radiographic studies, or during abdominal surgery performed for other indications. Asymptomatic ovarian mature cystic teratomas are reported at a rate of 6-65% in various series. When s Bladder symptoms, gastrointestinal disturbances, and back pain are less frequent. When abdominal pain is present, it usually is constant and ranges from slight to moderate in intensity. Torsion and acute rupture commonly are associated with severe pain. Hormonal production is thought to account for cases of abnormal uterine bleeding, but histologic examination has not provided evidence of this theory. The masses are firm or hard in 83% of cases. Most are not tender and do not transilluminate. Testicular pain and scrotal swelling occasionally are reported with teratomas, but this is nonspecific and simply indicates torsion until proven otherwise. Hydrocele frequently is associated with teratoma in childhood. On examination, the testis is diffusely enlarged, rather than nodular, although a discreet nodule in the upper or lower pole sometimes can be appreciated. .[1]
