Teratoma
Why do benign teratomas recur?
Benign teratomas, although not aggressive or metastatic, do not require adjuvant chemotherapy or radiation therapy after curative surgery to fight the tumor. However, many benign teratomas recur after surgery and require further surgical treatment. The cause of benign teratoma recurrence is considered to be due to the persistent presence of oncogenic factors. Therefore, benign tumors can also recur, since the exact cause and pathogenesis of benign teratomas are still unclear clinically. Thus, prevention from an etiological perspective is not possible, and the only option is timely surgical removal upon tumor detection to prevent the benign teratoma from becoming malignant. For patients with benign teratomas, regular follow-up is necessary after curative surgery to monitor any changes in the condition. If signs of recurrence are detected, prompt intervention is necessary to prevent malignancy.
Will the teratoma recur after the ovary is removed?
For teratomas, ovarian tumor excision surgery is generally chosen. If the teratoma is too large, and the remaining ovarian tissue is insufficient, there is no need to preserve the ovary, or if the teratoma has severe torsion causing ovarian tissue necrosis, an oophorectomy is necessary. After the oophorectomy, recurrence on the same side is generally not observed, but there is sometimes a possibility of recurrence on the opposite side, though the likelihood of recurrence is very low. Generally, if one ovary is removed due to a teratoma, the recurrence rate on the opposite side is usually less than 10%. Treatment of teratomas is generally surgical, and if not treated timely, complications such as torsion may occur.
Can one have sexual intercourse with a teratoma?
Teratoma is a type of ovarian cyst located within the abdominal cavity. Generally, the presence of a teratoma does not affect the patient's ability to have a normal sexual life. However, it is advised not to engage in overly vigorous sexual activity, as intense sexual activity can cause torsion of the ovarian cyst in the abdominal cavity. Once torsion of the ovarian teratoma occurs, it can lead to torsion of both the fallopian tube and the ovary on the affected side. Following torsion, the twisted fallopian tube and ovary lack blood supply, which can further lead to ischemia and necrosis. In such cases, it becomes necessary to surgically remove the affected fallopian tube and ovary.
Is ovarian teratoma a major surgery?
Generally, ovarian teratomas are considered major surgeries and are closely related to the nature of the teratomas. These are common major gynecological surgeries. It is recommended to visit the obstetrics and gynecology department for comprehensive examinations and a full-body assessment. Additionally, procedures such as biopsy are needed to determine the nature of the tumor, after which an appropriate treatment plan can be chosen. Options generally include open surgery or laparoscopic surgery, both of which are relatively major procedures.
Teratoma Benign and Malignant Differences
Teratoma refers to a common type of germ cell tumor, which can be classified into mature teratomas and immature teratomas. Mature teratomas are benign tumors, accounting for 10%-20% of ovarian tumors. They can occur at any age but are more common between the ages of 20 and 40. Most are unilateral, of moderate size, and usually have a single compartment filled with sebum and hair; sometimes teeth and bone can also be found. Immature teratomas, on the other hand, are malignant tumors, making up 1%-3% of ovarian teratomas. These are more frequent in younger patients, with an average age of 11 to 19 years. The ovaries are predominantly solid but may include cystic areas, primarily consisting of primitive neural tissue. The malignancy level of the ovary depends on the proportion of immature tissue, the degree of differentiation, and the content of neuroepithelial tissue.
Can a teratoma be detected by ultrasound?
Teratomas are a common type of solid tumor in the ovaries, and the vast majority of ovarian teratomas are benign. The most common method to examine teratomas in women is to perform an ultrasound. Generally, an abdominal ultrasound can be done 3-7 days after the menstrual cycle has ended to observe the ultrasonic echo of both ovaries. Normally, both ovaries are uniform in size and echo. If the ultrasound suggests the presence of a substantive mass on the ovary, which has a strong echo, or indicates the presence of fat or bone echoes, then this condition is highly suspected to be a teratoma. For ovarian teratomas, if the size is relatively small and there are no clinical symptoms, temporary observation is possible. However, if it is larger than five centimeters, laparoscopic removal is generally recommended.
Will teratoma recur after resection?
Teratomas in ovarian cysts are a type that can recur after surgery. After surgery, teratomas require close monitoring, and if recurrence occurs, reoperation for removal is necessary. Therefore, regular gynecological ultrasound post-surgery is key to confirm whether the teratoma has recurred. It is recommended that patients undergo regular gynecological ultrasound examinations at their local hospital after surgery, and if a recurrence of the teratoma occurs, seeking medical attention promptly is crucial.
Why does a teratoma have hair?
Mature teratomas contain lipids, hair, and even bone and other tissue structures within the tumor cavity. The main reason for this is that teratomas are composed of cells from multiple embryonic layers. These embryonic layer cells can develop in different directions, further developing into tissues such as hair, lipids, or bones. Therefore, during surgical procedures, it is common to find hair within the teratoma.
What are the symptoms of teratoma?
Ovarian teratomas can cause abdominal pain and might even result in sudden abdominal enlargement, often accompanied by symptoms like bloating. Women experiencing these symptoms are advised to seek medical attention promptly. Ovarian teratomas are more commonly found in younger women, particularly during their reproductive years. Thus, female patients experiencing these symptoms should promptly undergo an ultrasound at a hospital to check for the presence of teratomas and also have a blood test for tumor markers. If a teratoma is present, it is recommended to undergo surgical treatment as soon as possible due to the risk of malignant transformation.
Can women with ovarian teratomas have children?
Ovarian teratomas, if discovered after pregnancy, do not significantly impact the child; however, it's crucial to confirm that the ovarian teratoma is benign. If detected during pregnancy, close observation is possible, and sudden lower abdominal pain may indicate ovarian torsion, which requires timely surgical intervention. If there are no symptoms, surgery can wait until after the child is born. If an ovarian teratoma is discovered before pregnancy, it is advisable to undergo surgery before becoming pregnant because ovarian teratomas can sometimes be malignant, and torsion may occur during pregnancy, which could affect the child.
