Abstract

Lobular endocervical glandular hyperplasia of uterine cervix is a benign, exceptional lesion with a characteristic proliferation of miniature, spherical glands accompanied by gastric type differentiation. The discrete lobules incriminate upper endocervical canal of predominantly premenopausal women. Lobular endocervical glandular hyperplasia and gastric subtypes of cervical glandular lesions appear non concurrent to persistent infection with high risk variants of human papilloma virus (HPV). Cytological examination depicts mono-layered sheets of tall, columnar, mucinous cells demonstrating smooth nuclear outline with absent cellular or nuclear atypia or mitotic figures. Papanicolaou stained smears exemplify extracellular or intracellular, golden yellow mucin, indicative of gastric subtype of cellular differentiation. The well-defined lobular or acinar lesion is comprised of a centric crypt with circumscribing glandular articulations and miniature, spherical cysts which configure a floret-like pattern. Centric and peripheral glands are layered with columnar epithelial cells pervaded with pale, eosinophilic cytoplasm, bland, miniature, basal nuclei with mild nuclear atypia. Atypical cytological and architectural features may progress into the malignant ‘atypical lobular endocervical glandular hyperplasia’, currently contemplated as a category of gastric type adenocarcinoma in situ (GAIS). The lesion is immune reactive to pyloric gland mucin (HIK1083), MUC6, PAX2 or chromogranin A. Lobular endocervical glandular hyperplasia of uterine cervix requires segregation from neoplasms such as human papilloma virus (HPV) independent endocervical adenocarcinoma, gastric type, pyloric type metaplasia, gastric type adenocarcinoma in situ, type A tunnel clusters, micro glandular hyperplasia and mesonephric remnants or mesonephric hyperplasia of uterine cervix. Lesions detected upon surgical tissue sampling, cervical loop electrosurgical excision procedure (LEEP) or conisation may be optimally managed with total abdominal hysterectomy
