A 65-year-old man visited our hospital for right inguinal tumor. He had undergone gastrectomy for gastric carcinoma 13 years ago. Histopathologically, it was poorly differentiated adenocarcinoma, classified as t2(ss)n0M0 stage Ib according to the 12th edition of the Japanese Classification of Gastric Carcinoma. Six years ago, he underwent resection and radiation therapy for cutaneous metastasis of the right posterior head. Physical examination revealed a 3-cm elastic hard mass with good movement in the right inguinal portion. CT of the neck, chest, and body showed a tumor of 2.7×2.5×1.2 cm in the right inguinal portion. No other metastasis was found. Tumor resection biopsy was performed under local anesthesia. Histopathologically, it was lymph node metastasis from gastric carcinoma. Cutaneous metastasis and inguinal lymph nodal metastasis are often encountered as part of systemic metastasis in the terminal stage of gastric carcinoma, but solitary metastasis is very rare. Delayed metastasis, 7 and 13 years after gastrectomy, is also rare. We report and review this case with a review of the literature.
