Hemangiolymphangioma is a very rare benign vascular tumor that affects the gastrointestinal tract in less than 1% of cases. We present the case of an asymptomatic 52-year-old female referred for endoscopic colorectal cancer screening. A sub-epithelial pediculated polypoid lesion in the splenic angle of the colon was identified. An endoscopic ultrasonography with a miniprobe was performed, which identified an anechoic lesion in the submucosal layer. Surgery was performed and the histologic findings were compatible with two hemangiolymphangioma lesions. This is one of the few cases reported in the literature of hemangiolymphangioma diagnosed by miniprobe endoscopic ultrasonography and the first to describe two lesions in the same patient.
