title: Massive occult haemoperitoneum following spontaneous rupture of duodenal gastrointestinal stromal tumour.
abstract: Gastrointestinal stromal tumours are an uncommon subset of mesenchymal tumour that can occur anywhere along the gastrointestinal tract. Diagnosis of gastrointestinal stromal tumours is often difficult, as presentation is variable. This case report identifies massive haemoperitoneum as an initial finding, which is an unusual mode of presentation in gastrointestinal stromal tumours.
