A Case of Early Gastric Cancer with Synchronous Multiple Bone Metastases

ABSTRACT

The prognosis of an early gastric cancer (EGC) is generally excellent, with a 5-year survival rate of 90% in most reports; however, there have been few reports of EGC with distant metastases. Recently we encountered a rare case of EGC with synchronous multiple bone metastases. A 43-year-old woman visited a local clinic due to back pain. Lumbar spine metastases were suspected by MRI. She was transferred to our hospital and underwent bone marrow biopsy which revealed an adenocarinoma. After endoscopic evaluation for primary cancer work-up, we found a suspicious EGC lesion. The results of endoscopic biopsy was signet ring cell carcinoma. Our pathologist additionally reviewed the bone marrow biopsy slides and found signet ring cells in it. PET CT showed disseminated multiple bone metastases but, there wasn't any other malignant lesion. Here we report a rare case of EGC with synchronous multiple bone metastases.
