Figure 1: Case 1: (A) scanning magnification of the tumor, showing an ovarian adenocarcinoma (left) with associated cystadenofibroma (right). (B) Ductal pattern, mimicking endometrioid adenocarcinoma. Note the admixed small glands and tubules with eosinophilic secretions. (C) Sex cord-like pattern with cords, trabeculae and elongated tubules. Compare this photomicrograph with figure 11 of Clement et al. [10]. (D) Intense apical cytoplasmic and luminal immunoreactivity for CD10.
