A 38-year-old woman presented with sudden onset of haematemesis and melaena. She had no abdominal pain or jaundice, and she had not taken drugs before the bleed. On examination, she had cutaneous features of neurofibromatosis (Figure, A). Upper gastrointestinal endoscopy showed a smooth polypoidal mass, with central umbilication, in the body of stomach (Figure, B). A contrast-enhanced computed tomography scan of the abdomen showed an exophytic mass confined to the stomach. Following another haematemesis, the patient underwent an emergency sleeve resection of the mass. Histopathological examination of the removed tissue revealed spindle-shaped neoplastic cells with elongated nuclei arranged in fascicles (Figure, C), and immunostaining (Figure, D) was positive for CD117 (c-KIT), confirming gastrointestinal stromal tumour (GIST).

The prevalence of GIST in neurofibromatosis type 1 (NF1) varies between 4% and 25%.1 The clinical presentation of GIST associated with NF1 is similar to sporadic GIST but differs in being multiple; large, often involving the small intestine; and having a favourable prognosis.1 Several cutaneous syndromes are associated with gastrointestinal haemorrhage as a prominent feature. Prompt recognition of these disorders is required as early intervention can be life saving.
