Congenital Disseminated Pyogenic Granuloma: A Case With Numerous Mucocutaneous and Visceral Lesions
Congenital disseminated pyogenic granuloma (CDPG) is characterized by eruptive disseminated or localized lesions, which may arise spontaneously or secondary to predisposing factors. Even rarer is the occurrence of CDPG with numerous lesions affecting variable organs, which develop during the fetal period. This report describes the case of a 32-week-old fetus presenting with severe hydrocephalus and vascular intracranial and right lung masses on magnetic resonance imaging. Preterm labor occurred at the 32nd week due to preterm premature rupture of membranes, and the newborn died due to cardiac dysfunction within 2 hours postpartum. The subsequent autopsy revealed multiple violaceous to dark red papules, nodules, pedunculated and un-pedunculated mucocutaneous masses, as well as two brain lesions, a lung lesion, a thoracic wall intramuscular mass, and a pyloric mass. Microscopic examination and immunohistochemical evaluation for glucose transporter 1 (GLUT1) confirmed the diagnosis of CDPG. CDPG represents a rare condition with an elusive etiology and limited reports in the literature. Differential diagnosis from multifocal infantile hemangioma, based on GLUT1 negativity of CDPG, is imperative due to differing clinical course and treatment modalities. This report underscores a severe case of CDPG characterized by preterm labor and demise shortly after delivery, notable for its extensive involvement across multiple organs, including the brain, lung, intestine, musculoskeletal system, mucosal, and numerous cutaneous sites.
