Gastric Signet Ring Cell Carcinoma Presenting with Widespread Osteoblastic Metastases

Abstract

Gastric cancer infrequently metastasizes to the bone. These metastases are generally osteolytic. On the other hand, osteoblastic metastases are very rare. In this case report, a patient with signet ring cell gastric carcinoma presenting with diffuse osteoblastic bone metastases who had no laboratory abnormalities at the time of diagnosis is described. To our knowledge, our patient represents the longest surviving case compared with the similar cases in literature.
