Isolated Solitary Metachronus Perirenal Metastasis in a Distal Gastric Cancer

[摘要] Background:  Perirenal metastasis in gastric adenocarcinoma is rarely reported. We report an isolated solitary perirenal metastasis from gastric adenocarcinoma in a metachronus setting. Case Report:  A 46 year old male patient, with a history of carcinoma stomach, and distal gastrectomy and adjuvant chemo-radiotherapy, came for regular follow up.  His four year follow up CT scan showed a 3×3×3 cm mass in right perirenal space and it was FDG avid on PET CT. He underwent robot assisted laparoscopic excision of mass. It was adenocarcinoma suggestive of metastasis. Patient responded to 6 cycles of chemotherapy after metastectomy. This is the first case of isolated metachronus perirenal metastasis from adenocarcinoma of stomach. Conclusion: Gastric malignancy requires stringent follow up for timely detection of any metachronous metastasis and its appropriate treatment.
