Low-grade extrauterine endometrial stromal sarcoma of the peritoneum: A case report and literature review.

Endometrial stromal sarcoma (ESS) is an uncommon mesenchymal tumor that accounts for less than 1% of all primary uterine malignancies and extrauterine endometrial stromal sarcoma (EESS) is even rarer. We report the case of a 75-year-old woman with an abdominal tumor and multiple peritoneal implants. Histological analysis of the surgical specimens showed bland cellularity resembling normal endometrial stroma.

[Sentinel lymph node biopsy technique in colon cancer. Experience in 125 cases].

Introduction: The level of lymph node involvement is the most important factor in staging colorectal cancer without metastasis. Sentinel lymph node mapping identifies the node(s) that most accurately reflect the lymph node status of patients, and intensive techniques that improve staging can be focused on these nodes. The aim of this study was to assess the efficacy of ex vivo sentinel lymph node mapping in the staging of colon cancer.
