Adenoma malignum. Report of a case with cytologic and colposcopic findings and immunohistochemical staining with antimucin monoclonal antibody HIK-1083.
BACKGROUND
Adenoma malignum of the uterine cervix was first described by Gusserow. We report here a case with cytologic, histologic and colposcopic findings and immunohistochemistry for HIK-1083.


METHODS
A 42-year-old female was noted to have a probable adenoma malignum due to the detection of atypical cells classified as V. On colposcopy, comma-shaped, atypical vessels spread over the entire cervical area. Histologic findings were characteristic of tumor invasion beyond the layer of cervical glandular ducts. Immunohistochemical detection of CEA was negative, but HIK-1083, which recognizes gastric glandular mucous cells, was positive.


CONCLUSIONS
For a definitive diagnosis of adenoma malignum of the cervix, immunohistochemical examination for an appropriate marker, such as HIK-1083, should be added to the routine gynecologic examination, cytologic and histopathologic examination, and colposcopy.
