63. Microglandular hyperplasia of endocervix. H & E, higher magnification 47 Differential Diagnosis. Several features may help to differentiate a microglandular hyperplasia from an invasive carcinoma. The cells of micro glandular hyperplasia show less nuclear atypia; their cytoplasm contains mucin, not glycogen. In contrast to invasive adenocarcinoma, microglandular hyperplasia reacts negatively for CEA. Polyps of the Ectoand Endocervix (Figs. 65-67) Focal proliferation of the endocervical mucosa leads to polyp formation.

H & E, higher magnification 34 Hormonally Induced Changes Estrogens and gestagens act as antagonists not only on the endometrium but also on the ecto- and endocervix (Dallenbach-Hellweg 1981; Table 1). Effects of Estrogen (Figs. 46-53) Parakeratosis and Hyperkeratosis of the Ectocervix Estrogens stimulate proliferation of the squamous epithelium of the ectocervix, resulting in a well-developed superficial cell layer often covered by a fairly thick layer of parakeratotic cells (Figs.

The glands may ramify (Fig. 56) or become crowded (Fig. 57). The production of mucin is reduced or absent and occurs irregularly from one gland to another (Fig. 58) or within the same gland (Figs. 59, 60). Cells with mucin and those without may lie together, In addition, the chemical composition of the mucus is often changed (Gaton et al. 1982). The reserve cells underneath the glandular and superficial epithelium may undergo hyperplasia to form several layers. That hyperplasia is stimulated by the gestagens.
