Endometrioid Adenocarcinoma with High-Grade Transformation with Serous and Choriocarcinomatous Differentiation - A Case Report
نویسندگان
چکیده
A choriocarcinoma component with a malignant tumor is relatively rare. We present a case of an 85-year-old woman with mixed carcinoma, which was endometrioid adenocarcinoma with squamous differentiation, choriocarcinoma and a disseminated peritoneal nodule, which was papillary serous adenocarcinoma. The patient received surgery and conservative treatment. Twenty weeks after surgery, a recurring tumor appeared at the Douglas pouch. Histology showed that the recurring tumor was poorly differentiated carcinoma that was very different from the primary tumor. This case represents an unusual uterine corpus cancer with high-grade transformation with serous and choriocarcinomatous differentiation. This case also demonstrates the capacity of tumor cells to differentiate into divergent elements.

Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcino...

We report a case of gastric intramucosal adenocarcinoma giving rise to a large metastatic intraabdominal mass with focal choriocarcinomatous differentiation. The main histological picture of the surgically resected abdominal tumor was well differentiated adenocarcinoma with focal choriocarcinomatous differentiation. Serum hCGβ level showed 710mIU/dl postoperatively, and the gastric lesion featu...
