RESUMO
BACKGROUND Although recurrence after surgery for esophagogastric junction (EGJ) adenocarcinoma frequently develops in the mediastinal and para-aortic lymph nodes (LN), distant LN recurrence in the mesocolon is rare. We report a rare case of ileocecal LN metastasis in the ascending mesocolon after radical surgery for an EGJ adenocarcinoma. CASE REPORT We performed subtotal esophagectomy with mediastinal and para-gastric LN dissection in a patient with an advanced EGJ adenocarcinoma. Clinicopathologically, the patient was diagnosed with type I EGJ adenocarcinoma based on Siewert's classification (pathological T3N1M0). One year after surgery, computed tomography showed enlarged lymph nodes around the ileocolic artery, and further examination was performed. Although positron emission tomography-computed tomography showed that the lesion had moderate uptake of fluorodeoxyglucose, we did not find the reason for the enlarged lymph nodes. Finally, laparoscopic ileocecal resection was performed for diagnostic and therapeutic purposes. Clinicopathological tests revealed that the specimen was a moderately differentiated adenocarcinoma, which was strongly suspected to be a metastasis of the EGJ adenocarcinoma. CONCLUSIONS We encountered a rare case of EGJ adenocarcinoma that spread to the ileocecal LN in the ascending mesocolon. To the best of our knowledge, this is the first such report in the literature to date. Laparoscopic ileocecal resection for metastasis to the ascending mesocolon seems reasonable as a local control.
