A 74-year-old woman underwent a distal pancreatectomy for stage IIA cancer of the pancreatic body (JPS 7th) in February 2013. She received S-1 as adjuvant chemotherapy for 6 months. In February 2015, computed tomography scan showed a left inguinal mass, and FDG-PET imaging showed abnormal uptake in the left inguinal mass. Metastasis of pancreatic cancer to the left inguinal region was suspected and no other metastases were detected. In March 2015, the left inguinal mass was resected. An inguinal hernia was not detected during the operation. Histological examination of the resected mass revealed well-differentiated adenocarcinoma compatible with a metastasis from the pancreatic cancer. The patient survived for 54 months after distal pancreatectomy and 29 months after resection of the metastasis until August 2017, when she died of pneumonia. Metastasis of pancreatic cancer to the inguinal canal in women is very rare, especially in the absence of an inguinal hernia.
