Unexpected location of endometrial adenocarcinoma - a case report.

Endometrial adenocarcinoma (ADK) is one of the most common uterine cancer and the fourth neoplasia mortality cause in women according to the literature data. ADK is encountered in the sixth decade of life, the mean age being 63 years. Only 2-5% of cases are found in women less than 40 years old. We present the case of a 63-year-old woman admitted in our Clinic for hypogastric pain and reduced vaginal sanguinolent discharge. The genital examination and transvaginal ultrasound (US) scan were strongly suggestive for a type 0 myoma tending to be expelled through the cervical canal. Laparotomy and total hysterectomy with bilateral adnexectomy were performed. Histological examination identified a grade G1 well-differentiated endometrioid ADK without uterine wall invasion. The immunohistochemistry study for estrogen receptors expression revealed moderate and strong nuclear immunostaining in more than 70% of the tumoral cells, as well as a mosaic p16 immunoexpression, a cytokeratin 7 (CK7) immunophenotype, no p53 overexpression and low Ki67 index (estimated at 10-15%). Considering the incidental finding, the early stage and limited localization of the ADK at the myoma surface level surgery was considered sufficient as treatment but follow-up was conducted by magnetic resonance imaging (MRI) and general examination every six months. The most interesting aspect of the case was the atypical presence of an active myoma in menopause and the totally unsuspicious US appearance of the endometrium. The endometrial ADK was accidentally discovered in an unusual specimen without any other symptom.

A rare case of synchronous ovarian tumors: clinical case report and literature review.

Epithelial ovarian carcinoma makes up 90-95% of all ovarian malignancies, taking into account also low-malignant-potential tumors. The Krukenberg tumor is a rare metastatic adenocarcinoma (ADK) in the ovary, representing 1-2% of ovarian tumors. Multiple primary malignant neoplasms may exist when more than one cancerous tumor is diagnosed in the same or a different organ. The incidence of multiple primary cancers among malignancies is between 2.4% to 8%. The aim of this paper is to report the case of a 47-year-old patient with two synchronous malignant tumors involving both ovaries, one diagnosed as primary papillary serous cystadenocarcinoma and the other one diagnosed as ovarian metastasis (Krukenberg tumor) of a synchronous colorectal ADK, and the complex diagnostic and therapeutic challenges that such a rare case poses. Histopathological (HP) examination and especially the immunohistochemical analysis had a determining role in differentiating between an ovarian primary tumor and a metastasis from a gastrointestinal tract cancer. The tumors examination for somatic mutations of Kirsten rat sarcoma viral oncogene homolog (KRAS) and neuroblastoma RAS viral oncogene homolog (NRAS) genes was performed in order to individualize the chemotherapic treatment in this difficult case. The conclusion of this case is that, although synchronous multiple primary cancers in a young patient are a rare condition, this situation should be taken into account in the differential diagnosis when we encounter clinical and HP diagnostic challenges.
