RESUMEN
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.

Abstract: Rapidly involuting congenital hemangioma is a rare vascular tumor that generally has a good prognosis. The authors describe a case of a newborn girl with a left cervical vascular lesion. Image exams were performed, and the lesion slowly decreased, leaving redundant skin. Considering all of the findings, a final diagnosis of a rapidly involuting congenital hemangiomas was suspected.
