EPSTEIN, Marina Gabrielle et al. Hemoperitoneum secondary to gastric GIST negative for c-KIT and positive for antibody anti-DOG1. Einstein (São Paulo) [online]. 2012, vol.10, n.3, pp. 377-379. ISSN 1679-4508. http://dx.doi.org/10.1590/S1679-45082012000300022.
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.
