Congenital Disseminated Pyogenic Granuloma: Characterization of an Aggressive Multisystemic Disorder.

Area of Science:

• Pediatric Pathology
• Vascular Anomalies
• Dermatology

Background:

• Congenital disseminated pyogenic granuloma is a rare multisystemic disorder.
• It presents with multiple vascular lesions affecting various organs.
• Cerebral hemorrhagic involvement poses significant morbidity.

Purpose of the Study:

• To delineate the clinical, radiologic, and histopathologic characteristics of congenital disseminated pyogenic granuloma.
• To highlight the association with severe cerebral hemorrhagic complications.
• To emphasize the importance of differentiating this entity from other vascular lesions.

Main Methods:

• Retrospective review of medical records from a specialized vascular anomalies center (1999-2019).
• Inclusion criteria: patients with multiple vascular lesions and histopathologic diagnosis of pyogenic granuloma.
• Analysis of imaging, histopathology, and clinical data.

Main Results:

• Eight children presented with congenital multifocal cutaneous vascular tumors.
• Lesions commonly involved the brain, liver, spleen, muscles, bone, retroperitoneum, and intestine.
• Hemorrhagic visceral and cerebral lesions led to severe neurologic sequelae.

Conclusions:

• Congenital disseminated pyogenic granuloma is a distinct, aggressive multisystemic disorder.
• It affects the skin, brain, viscera, and musculoskeletal system.
• Distinguishing it from other vascular lesions is vital due to potential cerebral hemorrhage.
