  • Title: Problems in cervicovaginal cytology: fine structure as an aid to diagnosis.
    Author: Stanbridge DM, Butler EB, Langley FA.
    Journal: Acta Cytol; 1980; 24(4):335-43. PubMed ID: 6932147.
    Abstract:
    The ultrastructure of cytologically abnormal, thick cell groups and epithelial fragments in cervical and vaginal scrape material was investigated and found to be useful in differentiating between carcinoma in situ, invasive nonkeratinizing squamous carcinoma and adenocarcinoma of the endocervix and also in confirming the presence of cytologically suspected vault deposits of recurrent endometrial adenocarcinoma. It was demonstrated that although accurate evaluation of these thick groups in smear preparations is often not possible, thick sections of similar, plastic-embedded material showed some features which enabled a distinction to be made between squamous and glandular lesions and that these differences were more pronounced at the ultrastructural level. The squamous lesions were characterized by wide intercellular spaces with microvilli and tonofibrils within the cytoplasm while glandular lesions showed narrow intercellular spaces, prominent Golgi zones and endoplasmic reticulum together with mucus droplets in some cells.
