The tendency of smooth muscle tumors of the gastrointestinal tract to produce massive acute hemorrhage is well known.1 It is not generally appreciated, however, that about 10% of patients with these tumors present a characteristic syndrome2 enabling those familiar with it strongly to suspect, or actually to diagnose the condition on clinical grounds. The gross and microscopic appearance of the tumor is also quite characteristic. The case reported here is a typical example of this syndrome, but it is unusual in that massive bleeding occurred without showing evidence of mucosal ulceration—which is considered to be the cause of hemorrhage in the majority of cases.2
