It is very rare that metastatic tumors occur in oral region. Gastric carcinoma is typically asymptomatic, it can be discovered in later stage when it metastases. 54 years old male referred to our department with complaint of a mass(3.5×2.5cm) which was occurred 2 weeks ago, in the vestibule next to left second incisor. In the extra-oral examination lip was slightly expanded. No lymphadenopathy was determined in the cervical region. No pathological sign was noticed in the medical history. In radiological examination has been seen radiolucent lesion with irregular margins. It was considered as primary malign lesion and resected. Histopathological examination revealed high-grade undifferentiated tumor and the patient was scanned with positron emission tomography(PET). PET showed a mass in stomach, metastasis in the peripheral lymph nodes. Esophagogastroduodenoscopy performed. It revealed necrotic mass in stomach. Biopsy was made and diagnosed, undifferentiated carcinoma. Chemotherapy was given. His health got worse. Metastatic tumors originating from gastrointestinal system can spread through Batson's plexus. When a metastatic tumor occurs as first symptom, it gives an opportunity to cure the disease in early stage. So existence of a malign lesion in oral tissues, it is important to search a possible metastatic relation with any malignancies elsewhere in the body that can lead lethal prognosis.
