A case of vaginal adenosis

The mucosa of the vagina in normal women is lined with thick nonkeratinizing squamous epithelium. The vaginal adenosis is defined as the abnormal presence of glandular epithelium or columnar epithelium with secretary product in the vagina. The incidence of vaginal adenosis was highly increased when diethylstilbestrol(DES) was in wide use by the mid 1940s. A 44-year-old woman without the previous intrauterine DES-exposure visited our clinic with pain on external genital area and erosive red erythematous patch on the vagina. Histopathologically, the multiple glands consisted of the columnar epithelium existed in the lamina propria of vaginal mucosa. And the lining cells resembled those cells of the fallopian tube and endometrium, namely mucinous columnar cells. We report a case of vaginal adenosis in a 44-year-old woman.
