(a) Tridimensional hyperchromatic groups (H&E, x200), (b) Glandular group shows round overlapping nuclei with occasional mitosis and palisading nuclei at the periphery (H&E, x400). (c) Atypical glandular cells with hyperchromatic palisading nuclei (H&E, x400). (d) Cervical biopsy with central foci of ectopic endometrial glands surrounded by endometrial stroma and lined in the periphery by unremarkable endocervical glands (H&E, x100). Immunohistochemistry, shows (e) reactive endometrial glands and negative endocervical glands with vimentin (Vimentin, x100) and (f) reactive endometrial stroma with CD10 (CD10, x100)

The cervical cytology revealed tridimensional hyperchromatic glandular groups with nuclear overlapping [Figure 1a], round nuclei in the center, and palisading nuclei on the periphery of the cluster with occasional mitosis [Figure 1b and c]; no feathering was seen. Tissue sections revealed foci of ectopic endometrioid glands surrounded by endometrial stroma [Figure 1d] admixed with benign endocervical glands. Immunohistochemistry was reactive for vimentin on endometrioid glands [Figure 1e] and for CD10 in endometrial stoma [Figure 1f], but was negative in endocervical glands.
