[A Case Report of Cecal Cancer with Port Site Recurrence and Right Inguinal Lymph Node Metastasis after Laparoscopic Ileo‒Cecal Resection].

A 74‒year‒old man was diagnosed with cecal cancer and performed ileo‒cecal resection with D3 lymphadenectomy. The postoperative pathological diagnosis was pT3N0M0, pStage Ⅱa. He was followed up without postoperative adjuvant chemotherapy. One year after the surgery, he developed pain in the port area of the right‒lower abdomen, and CT showed a mass with contrast enhancement at the port site. In addition, a lymph node mass was observed in the right inguinal region. Because of severe pain at the port site, an excisional biopsy of the abdominal wall was performed for both diagnostic and therapeutic purposes. The pathological diagnosis confirmed metastasis of cecal cancer. An excisional biopsy of a lymph node in the right inguinal region was performed, and pathological diagnosis was a metastasis of cecal cancer. Two years have passed without postoperative chemotherapy, and he remains alive without recurrence. The metastasis was thought to have metastasized lymphatically to the inguinal region from the port site recurrence. We report on the port site recurrence and lymphatic metastasis from the metastatic lesion.
