The initial symptoms of epigastric pain, feeling of fullness, belching, and loss of appetite are non-specific and misleading. Nausea, vomiting and weight loss may accompany, which also complicate reaching a prompt diagnosis. In the presented case, a 15-year-old girl admitted with ascites, pleural effusion, right supra-clavicular lymphadenopathy, and back pain. No primary focus of a malignancy was accomplished in radiological evaluation, and the diagnosis of gastric carcinoma was achieved with upper gastrointestinal system endoscopy. We point out the importance of upper gastrointestinal system endoscopy in patients with ascites and uncertain diagnosis of the primary focus of malignancy.}, number={5}, author={Aydoğan, Ayşen and Corapçioğlu, Funda and Elemen, E Levent and Tugay, Melih and Gürbüz, Yeşim and Oncel, Selim} }
