Gross features of lobular endocervical glandular hyperplasia in comparison with minimal-deviation adenocarcinoma and stage Ib endocervical-type mucinous adenocarcinoma of the uterine cervix

摘要

Lobular endocervical glandular hyperplasia (LEGH) was first described as a benign mimic of minimal-deviation adenocarcinoma (MDA), or 'adenoma malignum'.Histopathological criteria for LEGH have well been established, but the distinction between LEGH and MDA in imaging studies is still challenging for diagnostic radiologists. Appearance of a multi-cystic lesion on computed tomography and magnetic resonance imaging has been considered to be diagnostic for MDA,but some authors have questioned this view, pointing out that cyst formation is rather uncommon in cases of MDA, but seems to be indicative of LEGH.
