RESUMEN
Yolk sac tumor (YST) coexisting with a variety of histologic patterns have been described, but with an epithelial malignant component is extremely rare. It has been suggested that this rare tumor represents an adenocarcinoma with aberrant differentiation because it occurs in the same age range as epithelial ovarian carcinoma and shows an aggressive behavior and poor prognosis. Although chemotherapy is effective for pure YST, YST with endometrioid adenocarcinoma does not respond to chemotherapy. Here the authors report a postmenopousal women with ovarian endometrioid adenocarcinoma (OEC) associated with YST.

Extensive keratinizing squamous change in endometrium, namely ichthyosis uteri, is an uncommon condition. It is considered a benign lesion but its association with malignancy has been reported in the literature. Here, we present two cases of ichthyosis uteri that were both diagnosed in the curettage material. If widespread squamous epithelium covering the entire endometrial surface is detected in the curettage, an advanced examination should be done because of the possibility of the underlying malignancy association.
