Rapidly Growing Congenital Disseminated Pyogenic Granuloma in the Scalp Treated with Staged Embolization and Excision: A Case Report

Abstract

Pyogenic granulomas are common, acquired vascular lesions that most often arise spontaneously or in sites of previous trauma. However, there are reports of a few cases that describe a rare condition, congenital disseminated pyogenic granuloma (CDPG), in which an infant either is born with or shortly after birth develops multiple pyogenic granulomas. A hallmark of CDPG is negative staining for glucose transporter 1 (GLUT-1) on immunohistochemistry, which helps distinguish it from the more common multifocal infantile hemangiomas. Because few case reports have described CDPG, much is unknown about its characteristics, clinical course, and most effective treatment options. Here, we present a case of an infant with a unique presentation of CDPG with lesions that are atypically large and growing at a rapid pace. We also describe a novel approach to treating large pyogenic granulomas in CDPG via staged glue embolization and surgical excision.
