Mucinous adenocarcinoma of the appendix with inguinal node metastases

Mucinous adenocarcinoma of the appendix is a rare neoplasm with a low propensity for lymph node metastasis. The present case refers to an appendicular mucinous adenocarcinoma with inguinal lymph node metastasis. A 71-year-old woman underwent an appendectomy due to a clinical presentation of acute a...

The present case refers to an appendicular mucinous adenocarcinoma with inguinal lymph node metastasis. A 71-year-old woman underwent an appendectomy due to a clinical presentation of acute appendicitis. However, the histological examination of the surgical specimen revealed a mucinous adenocarcinoma of the appendix. After staging, the patient underwent a right hemicolectomy and was proposed for adjuvant chemotherapy.
