Symptoms of vaginal melanoma

summary

My classmate has been in poor health, and she is also very weak. Today, during the Spring Festival, she told me that her lower body is a little uncomfortable, with some things growing, and some swelling. I accompanied her to the doctor. After a detailed examination, the doctor said that she had vaginal melanoma. Now I would like to share with you the symptoms of vaginal melanoma.

Symptoms of vaginal melanoma

First: the most common symptoms were vaginal bleeding (80%), vaginal discharge (7%) or vaginal mass (13%), a few patients had no symptoms, and they were found abnormal in vagina during physical examination. Some vaginal discharge showed black water, called "black belt". The time from symptoms to treatment for examination and evaluation ranged from 2 days to 4 months, with an average of 2.4 months. There may be bloody stench and purulent secretions when complicated with infection, and abdominal pain and difficulty in urination and defecation may occur in the late stage.

Second: vaginal melanoma has typical clinical manifestations. It is easy to obtain clinical diagnosis if vaginal lesions are found in gynecological physical examination. For suspicious patients, biopsy or excision of full-thickness lesions can be performed for pathological examination. The cutting edge includes 1-2cm normal vaginal mucosa, so as to prevent the tumor from spreading during biopsy. After rapid frozen examination of resected tissue, the scope of operation can be expanded according to the situation. Cytological examination of vagina is helpful to the rapid diagnosis of the disease. Non epithelial malignant tumor cells can be seen on the smear. HMB-45 histochemical staining can be used to assist the diagnosis if there is no melanin granules.

Third: melanoma can occur in any part of the vagina, most of the literatures reported that the tumor is often located in the lower 1 / 3 of the vagina (58% - 66%), the anterior wall (45%). The diameter of the tumor ranged from 0.2 cm to 10 cm. Single lesions were common. The color of the lesions varied from brown to black. There were also cases with or without pigment. The lesions were various in shape, including flat black spot, nodular, polypoid, cauliflower, papillary or surface ulcer.

matters needing attention

After confirming the diagnosis of melanoma, X-ray, ultrasound, CT and other examinations should be carried out to understand the pelvic situation and whether there is metastasis of lung, liver, brain and other common parts, so as to determine the staging of tumor and take corresponding treatment.
