A Case of Primary Endometrioid Adenocarcinoma of the Vagina

Primary cancer of the vagina is very rare, accounting for 1-2% of gynecologic malignancies. Vaginal cancers are composed of primary and metastatic one. Of them, metastatic cancers constitute the majority of vaginal cancers, as 80-90%. Differentiating as type of cancer cell, the squamous cell carcinoma is the most common, as 80-90%, but, the adenocarcinoma is rare, as 9% of primary vaginal cancer. Same as other disease, if there is a symptom, the 5 year-survival rate of the vaginal cancer is 37%, but, if not in early stage, that becomes higher, as 61%. So, the early diagnosis and treatment are very important for patients’ prognosis.
