Coumarins, such as warfarin or acitrom, are the most widely prescribed oral anticoagulants agents and have been associated more with the development of hematomas than direct factor X inhibitors, such as rivaroxaban [ 1]. Few reports have linked oral anticoagulation therapy with the development of muscular hematomas; however, clinical cases regarding the involvement of the sartorius muscle remain limited. Patients with advanced age, under oral anticoagulant therapy with pain and ecchymosis in the thigh region, should undergo radiological evaluation utilizing ultrasonography, computed tomography or magnetic resonance imaging to establish an accurate diagnosis. The following case consists of a patient that while resting presented with a spontaneous rupture and hematoma of the sartorius muscle secondary to rivaroxaban use. During follow-up, the patient recovered completely. Published by Oxford University Press and JSCR Publishing Ltd.

The diagnosis of GIST is typically made with upper endoscopy after excluding other causes of bleeding. The surgical management of GIST can be challenging depending upon the location of the tumor. We present a unique case of duodenal GIST in the setting von Willebrand's disease diagnosed after emergent laparotomy for massive gastrointestinal hemorrhage. Key strategies in curing our patie
