    Abstract:
    Congenital cutaneous pyogenic granuloma is a rare benign vascular tumor with clinical and histopathological features similar to infantile hemangioma. It usually presents as a red, pedunculated and highly friable papule. On histopathological analysis, one can see a capillary vessel proliferation with lobular pattern and endothelial proliferation. The differential diagnosis is based on negativity of glucose transporter 1 (GLUT1) immunochemistry studies. We report two infants with congenital pyogenic granuloma, one with a unique cutaneous lesion and the other with multiple lesions affecting both skin and mucosal surfaces. These two cases highlight the importance of the differential diagnosis based on the GLUT1 immunochemistry analysis considering the distinct treatments required to these infant vascular tumors.
