Although relatively rare, the gastrointestinal stromal tumors comprise most mesenchymal tumors of the digestive tract and account for 5% of all sarcomas. The most common symptoms are pain, gastrointestinal bleeding and palpable mass. This study reported the case of a young patient who developed hemoperitoneum due to gastric neoplasm rupture and required urgent surgical treatment. Pathology and immunohistochemistry analysis showed an epidemiologically rare case: epithelioid and c-KIT negative tumor.
