[A case of long-term survival after lateral pelvic lymph node dissection for recurrence as skip metastasis of rectal cancer].
Herein, we present a case of long-term survival after lateral pelvic lymph node dissection for recurrence in the form of skip metastasis of rectal cancer. A 63-year-old man underwent abdominoperineal resection without lateral pelvic lymph node dissection for advanced lower rectal cancer. The histological diagnosis was type 2, 85 × 50 mm, tub1, pT4a, ly0, v1, pPM0, pDM0 and pN0, pStage II (Japanese Classification of Colorectal Carcinoma, 8th edition). Six months after surgery, enhanced computed tomography showed right obturator lymph node metastasis. We performed lateral pelvic lymph node dissection. Histological examination revealed moderately differentiated adenocarcinoma in the right obturator lymph node. The lymph node metastasis was diagnosed as a skip metastasis of the rectal cancer. The patient has had no recurrence for 9 years after resection of the lateral pelvic lymph node.
