The Significance of Glandular Cells on Conventional Cervicovaginal Smears: Experience from a Tertiary Care Hospital in Coastal India

Introduction: Glandular lesions of the female genital tract (FGT) are quite uncommon compared to squamous lesions. Their cytological diagnosis is difficult because of their architectural and cytological complexity, as well as the lack of experience of many cytopathologists in this field. The aim of this study was to determine the significance of Papanicolaou (Pap) smears in the diagnosis of glandular FGT lesions. Methodology: All Pap smears reported during the period of January 2012 to December 2013 were retrieved. Cytohistopathological correlation was done. Results: Among 7,609 Pap smears, squamous epithelial abnormalities were seen in 110 cases (1.5%) and glandular cell abnormalities in 32 cases (0.42%). Among the glandular abnormalities, we encountered 18 cases of atypical glandular cells (AGC) not otherwise specified, 4 cases of endocervical-type AGC and 4 cases favoring neoplastic-type AGC, 2 cases of adenocarcinoma of the endocervical type, 3 cases of adenocarcinoma of the endometrial type, and 1 case of extrauterine adenocarcinoma. Histopathological correlation was available in 12 cases (37.5%). Eighty-three percent showed premalignant or malignant lesions on histopathology. Conclusion: As glandular epithelial lesions are associated with premalignant and malignant FGT lesions, in patients with cytological diagnosis of glandular epithelial abnormalities, it is mandatory to undergo colposcopic examination with endocervical and endometrial curettage.
