case_images: (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)

case_images: 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.
