A woman with poorly differentiated endometrioid adenocarcinoma of the ovary had sarcoid-like lesions in the bone marrow. Sarcoid-like lesions may be misinterpreted as metastatic disease, resulting in inappropriate modification of therapy.

A yolk sac tumor that arose within an ovarian endometrioid adenocarcinoma in a 50-year-old woman is described. The tumor had typical microscopic features, stained immunohistochemically for alpha-fetoprotein, and was associated with an elevated serum alpha-fetoprotein level when metastases appeared. This is the fourth case in which a yolk sac tumor has been reported to develop from a somatic carcinoma and the second in which this tumor has been associated with epithelium of endometrioid type. Tumor heterogeneity or neometaplasia may account for the origin of a tumor of germ cell type from a carcinoma of somatic origin.

Ovarian carcinoma, part of a heterogeneous group of tumours, is the main cause of death by gynaecological neoplasms. The diagnosis, in general, is delayed. Multiorgan diffusion, the necessity of a surgical operation and strong chemotherapy, and the eventual pathology due to patient age are all factors that require a multidisciplinary approach. In fact the case, here reported, refers to a patient who came under our observation for a bilateral ovarian mass discovered casually during an abdominal ultrasound exam carried out for renal colic. Excellent cytoreduction with peritoneal cytology, total abdominal hysterectomy, bilateral salpingo-oophorectomy (Figure 2), bilateral pelvic lymphadenectomy, total omentectomy, removal of nodules from the mesentery, the colon and three nodules in the abdominal wall thickness was executed. The histological report was G3, angioinvasive bilateral ovarian endometrioid adenocarcinoma. Metastasis was found only in one left obturator lymph node out of 17 lymph nodes removed. All of the removed abdominal, mesenteric and intestinal nodules were neoplastic. It is concluded that the complexity of similar cases always requires a multidisciplinary approach as in our case, involving an oncologist, hematologist, surgeon, gynaecologist, radiologist, anaesthesiologist, and nursing staff in the management of third stage ovarian cancer patients to obtain the best treatment thus guaranteeing a higher survival rate and better quality of life.

One histologic subtype of ovarian carcinoma, ovarian endometrioid adenocarcinoma (OEA), frequently harbors mutations that constitutively activate Wnt/beta-catenin-dependent signaling. We now show that defects in the PI3K/Pten and Wnt/beta-catenin signaling pathways often occur together in a subset of human OEAs, suggesting their cooperation during OEA pathogenesis. Deregulation of these two pathways in the murine ovarian surface epithelium by conditional inactivation of the Pten and Apc tumor suppressor genes results in the formation of adenocarcinomas morphologically similar to human OEAs with 100% penetrance, short latency, and rapid progression to metastatic disease in upwards of 75% of mice. The biological behavior and gene expression patterns of the murine cancers resemble those of human OEAs with defects in the Wnt/beta-catenin and PI3K/Pten pathways.

Extramedullary hematopoiesis (EMH) usually occurs in patients with severe anemia or myelofibrosis, and involvement of the serous cavities is uncommon. A total of 5 cases of peritoneal EMH are presented in patients presenting with primary gynecologic pathology including endometrial adenosarcoma (n=2), ovarian leiomyosarcoma, and ovarian endometrioid adenocarcinoma (each n=1), all of which were associated with peritoneal metastases; the remaining patient had a hemorrhagic benign ovarian cyst. All cases were associated with organizing peritoneal hemorrhage, and EMH was localized to the reactive granulation tissue. EMH was not identified within the tumor tissue in the 4 neoplastic cases. Erythroid precursors were present in all cases and granulocytic precursors and megakaryocytes were identified in two and three cases, respectively. There was no evidence of EMH in the corresponding peritoneal fluid cytology preparations examined in 4 cases. None of the patients had a significant hematological abnormality at the time of presentation or during a mean follow-up period of 35 mo (range, 2-66 mo). The mechanism of peritoneal EMH in these cases is uncertain but most likely related to tissue hemorrhage and repair as described in other sites such as dura, myocardium, and synovium. Pathologists should be aware that EMH may involve the peritoneum to avoid misinterpretation of the findings, particularly in small biopsy or cytology samples.
