Microglandular hyperplasia which may not be familiar in this country is a polypoid lesion of the cervix and has been noticed as the lesion sustained by contraceptive pills. The retrospective study was performed to clarify whether or not this lesion have been enclosed into diagnosis of cervical polyp at routine clinic. 1. Among 895 cases of cervical polyp resected at our clinic during 7 years from 1971, 7 microglandular hyperplasias were found, showing 0.8% of the incidence. 2. Ages of the 7 patients ranged from 42 to 52 years, and the average was 45.7. Three cases complained of metrorrhagia. 3. One woman was taking oral contraceptives and the other was on hormonal therapy. No patient was pregnant. 4. Polyps with microglandular hyperplasia were usually above the size of small finger tip. In one case, a large papillary mass (3.0 x 3.5 cm) resembling to carcinoma of the cervix was experienced. 5. There were no characteristic findings in cytology except a case with enlarged and vesicular cells. 6. Histologically, the lesion consists of numerous microglandular spaces lined by regular cuboidal or flat cells without atypism. The eosinophilic cytoplasms are not vacuolated. Glands are not clearly demarcated from edematous stroma. This change may be mistaken for adenocarcinoma.
