Introduction of vaginal malignant mullerian mixed tumor Vaginal malignant mullerian mixed tumor is a kind of gynecological disease. Malignant mullerian mixed tumor is more confusing in the literature. It is classified according to international oncology classification including carcinosarcoma, adenosarcoma, malignant mesodermal mixed tumor and malignant. Mixed mesenchymal sarcoma. basic knowledge The proportion of illness: the incidence rate is about 0.002% - 0.004%, more common with female women more common Susceptible people: women Mode of infection: non-infectious Complications: endometriosis
Cause
Vaginal malignant mullerian mixed tumor etiology
(1) Causes of the disease
The cause is still unknown.
(two) pathogenesis
1 Carcinosarcoma: The tumor contains two components of cancer and sarcoma. The cancer is more common with adenocarcinoma. The sarcoma is a vaginal homologous component such as smooth muscle and fibrous tissue.
2 glandular sarcoma: its epithelial component is a benign or proliferating glandular epithelium, but the interstitial component is a low-grade sarcoma;
3 malignant mesodermal mixed tumor: There are two components in the tumor, but the sarcoma is a heterogeneous component of the uterus, such as striated muscle, bone, cartilage, fat and other tissues, such as no epithelial components in the tumor, but contains more than two kinds of interstitial tissue. Mucinous liposarcoma is called malignant mixed mesenchymal sarcoma.

Symptom
Vaginal malignant mullerian mixed tumor symptoms common symptoms vaginal appearance of vaginal ... vaginal secretions increased polyps vaginal bleeding endometriosis

Examine
Examination of vaginal malignant mullerian mixed tumor
Tumor marker examination, secretion examination, histopathological examination. Colposcopy.
Diagnosis
Diagnosis and diagnosis of vaginal malignant mullerian mixed tumor
The diagnosis of vaginal primary malignant Müllerian mixed tumors, in addition to histological examination in line with malignant Müllerian mixed tumors, must also have:
1. Confined to the vagina, without involving the vulva or cervix.
2. With infiltration and metastasis.
3. Exclude other parts of the malignant tumor metastasis may be, for vaginal recurrence of endometriotic lesions, Judson et al (2000) proposed a need for biopsy to rule out the possibility of malignant disease.
Vaginal malignant mullerian mixed tumor should be differentiated from vaginal polyps and vaginal endodermal sinus tumors.
