title: [Presentation of gastric cancer as a soft tissue tumor].
abstract: Soft tissue metastasis of gastric cancer is extremely rare. We report an 82 year old male, who was being evaluated for benign prostate hyperplasia and incidentally a soft tissue mass in the right buttock was discovered. Differential diagnosis included neurofibroma vs. soft tissue sarcoma. Patient underwent surgical resection and pathologic analysis reported adenocarcinoma with ring cell differentiation. Postoperative work-up included a CT scan of abdomen and pelvis and upper gastrointestinal endoscopy. An ulcer in the gastric antrum was discovered and biopsied. Pathology reported the same tumor as the soft tissue mass. PET scan demonstrated extensive metastatic disease. We reviewed the literature looking for other cases of soft tissue metastasis of gastric cancer.
