INTRODUCTION Lung cancer represents one of the most common malignant diseases worldwide and the major cause of cancer related deaths accounting for 25% of all cancer deaths and with a 5 years survival rate of 10-20%. Approximately 40-50% of the patients with lung cancer at the time of diagnosis present with metastatic disease. The most common sites of metastatic spread include the liver, brain, adrenal glands and bones while abdominal metastasis is less common. Autopsy studies report a prevalence of abdominal metastasis ranging from 4.7 to 16%, but these metastases have a low rate of clinical presentation and seldom become symptomatic. Abdominal metastases are more common in the gastrointestinal tract and in the peritoneum and rarely present in the omentum. We present a case of asymptomatic metastases to the greater omentum from primary lung cancer diagnosed incidentally during laparotomy, which was the first presentation of lung cancer.
