Cervical HSIL Involving the Endometrium and Adenomyosis: A Case Report and Literature Review.

Cervical squamous cell carcinoma (SCC) spreading superficially to the inner surface of the uterus and replacing the endometrial lining cells with carcinoma cells is called superficial spreading SCC. We, hereby report a 53-year postmenopausal woman who had a history of cervical SCC in situ/high grade squamous intraepithelial lesion (HSIL). Ultrasonography revealed an enlarged uterus measuring 9.0×6.5×5.0 cm with dilatation of the uterine cavity and the cervical canal. Subsequently, she underwent total abdominal hysterectomy (TAH) and bilateral salpingo-ophorectomy with a diagnosis of cervical HSIL involving the endometrium and adenomyosis. This a very rare phenomenon, as the endometrial involvement may be caused by direct extension of the cervical lesion, and occur mainly in postmenopausal women, and should be deligently searched during pathological examination. Key Words: HSIL, Cervix, Endometrium, Adenomyosis.
