A 14-year-old male was seen in the basic surgery department of our hospital on December 26, 2024 due to "intermittent melena for more than 2 months". In October 2024, the child developed melena with fatigue without obvious trigger. He went to a local hospital. Routine blood examination showed hemoglobin 59 g/L, and abdominal CT examination showed stomach mass. After blood transfusion treatment, the hemoglobin rose to 112 g/L. Later, ultrasound gastroscopy was performed in the outer hospital, which showed that there were bulging lesions in the gastric body-antrum and ulceration in the gastric angle-antrum. There are mixed echo shadows in the liver-stomach space. A puncture biopsy of liver-stomach space mass was performed under the guidance of ultrasound in an external hospital. The pathological examination results showed that (liver-stomach mass) short spindle cells with epithelial morphology, suggesting gastrointestinal stromal tumor; CT scan-guided space-occupying puncture biopsy of the lung revealed (pulmonary) microscopic degenerative cartilage and mucoid components without atypia. The child was given oral imatinib on 18 October 2024, during which the hemoglobin dropped to 75 g/L and was accompanied by melena, and the drug was discontinued on 20 November 2024. The child has been healthy in the past, and his development is slower than that of his peers. The parents and brother are healthy, and they deny that there is a history of similar stomach and lung diseases and genetic diseases in the family.
