When it comes to tumors and cancer, I believe many people’s first feeling is fear. Cancer and tumors are a concern for people, and more and more people pay attention to cancer and tumor screening. In recent years, more and more people are suffering from tumors and cancers. This phenomenon is slowly becoming younger and younger. Some cancers and tumors develop very quickly. Maybe you are still saying "bear with it" or "see it again when you have time". "...by the time it had turned to another disease. Therefore, I would like to remind everyone that regular tumor and cancer screening plays a very important role! No, the 49-year-old Ms. Wu's belly is as big as pregnancy. However, she recently underwent surgery to remove a tumor that had been hidden in her body for more than 20 years, and found that it was full of hair and bones. Why is this?

It is understood that 49-year-old Ms. Wu from Hunan went to Hunan Provincial Women and Children's Hospital for treatment because her belly was as big as pregnancy. Ms. Wu said that she discovered a 5 cm abdominal mass during a physical examination in 2001, and now the diameter of the mass is 11 cm...

The doctor said that this was a type of teratoma. Although it was a benign tumor, it grew larger over time and began to affect Ms. Wu's normal life. "I felt some pressure (in the abdomen) and lay down. It was very obvious.” Because there is the word "fetus" and it grows in the abdominal cavity, it will be mistaken for pregnancy. In fact, teratoma is a tumor produced by abnormal differentiation of ovarian germ cells. It can grow by itself without sperm and eggs, so it is not Pregnant. It usually grows in the ovaries, sacrococcygeal bone, testicles, peritoneum, mediastinum and other locations. Ms. Wu's condition grew in the ovaries. Dr. Ouyang Zhuo, director of the Department of Gynecology, said: Ms. Wu is less than 1.6 meters tall but weighs 190 pounds. She has fat accumulation in her abdomen, which is very thick. Surgery on her abdomen would be very invasive, so the doctor considered removing the tumor from her vagina.

There will be greasy fat, hair, teeth and other bones in the teratoma. When the teratoma in Ms. Wu's body was removed, black hair was adhered to yellow fat. If the teratoma is not operated carefully, it is very easy to get infected. The surgery uses single-port laparoscopic technology. Single-port laparoscopic surgery is divided into transumbilical single-port laparoscopy and transvaginal single-port laparoscopy. Because single-port laparoscopy is difficult to operate, the surgical instruments have to pass through a small opening, and the field of view is narrow. , the operating space is also narrow, which extremely tests the operator's ability.

Speaking of teratoma, the editor has seen such an incident before. html A 129-year-old woman had long hair, bones, and fluid removed from her abdomen due to teratoma...

9-year-old Ms. Wang is married3 Years ago, I did not use contraception during this period, and I have never been pregnant! After being introduced by friends around her, she went to the hospital for treatment in June 2020. Later, an outpatient B-ultrasound examination revealed that Ms. Wang had a mixed mass on her right ovary, so our hospital treated the patient as "primary infertility, adnexal mass" Admission to hospital. After communication and consultation with Ms. Wang, preparations for surgery were immediately carried out.

Subsequently, the gynecology team, under the leadership of Director Zhao Minhui, performed hysteroscopy for Ms. Wang. During the operation, it was found that there was a cystic-solid mass of about 5*4*4cm in the right fallopian tube of Ms. Wang, which was treated surgically. , a large amount of grease-like viscous fluid, bones, hair, and a fully developed tooth were removed from the ovarian cyst.

How did everyone react when they saw this: panic, questions... Are you pregnant with a freak? In fact, it is all caused by this teratoma, so what exactly is this teratoma?

Teratoma is a common type of ovarian tumors . It is derived from germ cells and is divided into mature teratomas (benign teratomas) and immature teratomas ( malignant teratomas). Benign teratomas contain many components, including skin, hair, teeth, bones, grease, nervous tissue, , etc.; malignant teratomas are poorly differentiated, have no or little formed tissue, and have unclear structures. Most early-stage teratomas have no obvious clinical symptoms and are mostly discovered accidentally during physical examination.

There are several types of teratomas, 97% of which are cystic mature teratomas, also called dermoid cysts. It can occur in young girls as well as old women, but most of them occur between the ages of 20 and 30.

What exactly is teratoma?

So, if the name teratoma contains the word "fetus", does it have something to do with the fertilized egg? In fact, it is not caused by fertilized eggs, and its occurrence has nothing to do with sexual life or pregnancy. Teratoma is a tumor formed by the mutation of primordial germ cells in the human body. It most commonly occurs in the ovary, followed by the testis. In other words, men can also develop teratomas. In addition, it can also grow in the mediastinum, sacrococcygeal area, retroperitoneum, pineal gland and other parts.

In fact, in the absence of fertilization, the human body's primordial germ cells may also differentiate abnormally and differentiate into three types of tissues: ectoderm, mesoderm and endoderm, but ultimately fail to differentiate into complete organs, thus forming tumors. , this is a teratoma. Tumors may contain ectodermal components such as immature hair, grease, teeth, and bone fragments, as well as mesodermal or endodermal tissue, such as muscle, gastrointestinal, and thyroid tissue.

What are the symptoms of ovarian teratoma ?

Mature cystic teratoma can occur at any age, but it mostly occurs in women of childbearing age around 30 years old. According to the histopathological type, it is divided into mature teratoma, immature teratoma and ovarian goiter. The most common mature teratoma is mature cystic teratoma, also known as dermoid cyst. Immature teratomas have malignant biological behavior.

Teratoma does not have typical symptoms in the early stage, and has varying degrees of impact on menstruation. Symptoms of precocious puberty may also occur. Severe teratoma may cause complications such as pedicle torsion, teratoma rupture, infection, and malignant transformation.

Ovarian teratoma

• Abdominal pain: When pedicle torsion occurs, severe pain may occur.
• Abdominal distension: A mass can be felt in the abdomen. In the short term, ascites may appear due to the rapid growth of teratoma.
• Precocious puberty: breast development, early menstruation, etc. may occur.

Testicular teratoma

mainly manifests as swelling of the testicles and concurrent lumps.

Sacrococcygeal teratoma

Because it occurs in the sacrococcygeal region, urinary system symptoms may occur, such as constipation and difficulty urinating.

Other symptoms: Teratomas can cause patients to have symptoms of precocious puberty, such as breast development, pubic hair growth, etc. Malignant transformation of tumors or immature ovarian teratomas may manifest as signs of cachexia such as weight loss, severe anemia, and fatigue in the late stages.

The diagnosis rate of ovarian teratoma is relatively high through ultrasonic examination, and unilateral ovarian cyst solid mass can usually be seen; serological examination may show mild elevation of CA199, AFP, etc.

What are the dangers of ovarian teratoma?

. Tumors are at risk of rupture: Once the tumor ruptures and causes massive bleeding, dangerous situations such as acute abdominal pain and shock may occur.

. Others: Because teratomas contain many components, such as skin, hair, teeth, bones, grease, nerve tissue, etc., the center of gravity of the tumor will be biased to one side. When the patient moves or changes body position, it may occur. Rotation, torsion, etc., affect the blood supply of the ovary, causing ovarian necrosis, rupture, infection, and even shock.

Misconceptions about teratomas

Are teratomas inborn?

The age of onset of teratoma ranges from newborns to old women in their nineties. Ovarian teratomas generally occur in young women in their twenties and thirties, and will gradually grow with age. Teratomas are not brought from the mother's body, but are tumors that may erupt at any time.

Teratomas are also commonly found in men.

The name of teratoma is easy to misunderstand. The word "fetus" reminds people of pregnancy, which makes some innocent girls suffer injustice. And the legend that the so-called teratoma is a sibling has given it a certain legendary color. But in fact, the truth about teratomas is: tumors! Moreover, men can also suffer from teratomas, which further illustrates the universality of this disease and has nothing to do with pregnancy caused by sexual intercourse.

Teratoma has nothing to do with twins.

Teratoma is a kind of tumor. A tumor that originates in germ cells. Most teratomas are ovarian teratomas, which are caused by abnormal proliferation of egg cells. Because egg cells have totipotent differentiation functions, excessive proliferation leads to the formation of tumors. The egg cell has not been fertilized, so it is not true to say that it is the patient's twin sibling. No doctor will tell the patient that the teratoma came from pregnancy. Pregnancy-related tumors include mole, malignant mole and chorioepithelial carcinoma . Malignant mole and choriocarcinoma can also occur in non-pregnant women.

Will the removal of teratoma affect fertility?

It is possible to get pregnant normally after ovarian teratoma surgery, and it does not cause much harm to the body.

Teratoma is a very common ovarian tumor. There are many mature teratomas. The diagnosis is very easy and the treatment is not complicated. Once diagnosed, surgery should be performed in time. Therefore, it is recommended that every woman undergo a gynecological B-ultrasound examination every 6-12 months as a routine examination. If you find that you have teratoma, don’t be overly nervous. You should go to a professional hospital for early detection and early treatment!
