(a) The tumor in the ovary consists of glands lined with low cuboidal, polyhedral, hobnail or flattened cells with uniform nuclear atypia, and variable mitotic activity. Cytoplasmic clearing of tumor cells and background hyalinized stroma is prominent. (b) Extensive endometrioses were noted in multiple anatomical locations. The omentum is pictured here. (c) The tumor in the pleura consists of glands lined with tumor cells similar to those of ovarian cancer. Background hemosiderin-laden macrophage is prominent in this biopsy.
