A wide range of morphological patterns may be seen in intraductal carcinoma. (A) Dense cribriform structures partly involving a gland with (B) a retained basal cell layer on immunostaining for high–molecular weight cytokeratin and P63. Note the invasive carcinoma in the vicinity. (C) Dense cribriform glands. (D) Solid glands showing two-cell populations with central small and uniform nuclei and peripheral more pleomorphic nuclei. (E) Glands with comedonecrosis. (F) Intraductal carcinoma partly involving benign glands. (G) Glands with cells with marked variation in nuclear size and shape that are six or more times greater than the adjacent nuclei.

3. Fig. 2
(A) Atypical intraductal proliferation that is morphologically more atypical than high-grade prostatic intraepithelial neoplasia, with several large loose cribriform glands lined with uniform nuclei, but is insufficient for intraductal carcinoma. (B) Retained basal cell layer on immunostaining for high–molecular weight cytokeratin and P63.
