More than 90% cases of chronic gastrointestinal bleeding can be diagnosed by upper endoscopy and/or colonoscopy, and therefore, obscure gastrointestinal bleeding has been defined as bleeding of unknown origin that persists after these conventional endoscopic evaluation. Gastrointestinal stromal tumors (GISTs) are rare tumors, but the most common form of mesenchymal tumors of the gastrointestinal tract. Small bowel is the second most common primary site for GISTs, and accounts for 2-10% of chronic bleeding sites. GISTs usually present as a sporadic and solitary tumor, and a minority of the cases of multiple GISTs are discovered as forms of hereditary or idiopathic tumor syndromes. Small bowel tumor has been difficult to diagnose because of absence of accurate and proper diagnostic tools. Recently developed wireless capsule endoscopy helps in the diagnostic work-up of small bowel diseases. We report a case of multiple jejunal GISTs presenting melena in a 39-year-old male, which was diagnosed with wireless capsule endoscopy.
