Oviductal and endometrial tumors show endometrioid histology at both primary and satellite locations.

<p>Formalin fixed and paraffin embedded primary and metastatic tumor tissues were analyzed for histo-pathology. Representative images of H&E stained tumor sections are shown. Left column: primary tumors of the genital tract show endometrioid histology in the ovary, oviduct and endometrium. Right column: secondary tumors, including ovarian metastases to the diaphragm (upper), oviduct metastases to the pancreas (middle) and endometrial metastases to the diaphragm (lower) also show endometrioid histology. Scale bar −20 µm.
