Core Tip
Core Tip: Gastrointestinal bleeding due to small intestinal tumors, especially metastatic tumors, is rare. We describe a rare case of metastatic invasive mole that caused acute small intestinal bleeding. The capsule endoscopy and enteroscopy detected jejunal lesions with features of trophoblastic tumor on biopsy. The patient underwent resection of the involved jejunal segment. The histopathology of the resected specimen confirmed the diagnosis of invasive mole. For women of childbearing age, who present with gastrointestinal bleeding and elevated human chorionic gonadotropin, after pregnancy is ruled out, metastatic trophoblastic tumor must be included in the differential diagnoses.
