Congenital telangiectatic atrophic patch on a healthy child

Area of Science:

• Vascular anomalies
• Pediatric dermatology
• Congenital disorders

Background:

• Rapidly involuting congenital hemangiomas (RICHs) are rare vascular tumors.
• RICHs typically proliferate in utero, are fully grown at birth, and involute rapidly postnatally.
• A rare subset of RICHs can involute entirely in utero.

Observation:

• This report details a unique case of a RICH that underwent complete involution in utero.
• The infant presented at birth with an atrophic plaque and redundant skin, characteristic of a prenatally involuted RICH.
• Clinical presentation and diagnostic imaging were crucial in identifying this rare variant.

Findings:

• Prenatal diagnosis of RICHs is challenging but possible with advanced imaging techniques.
• Complete in utero involution of RICHs results in distinct clinical findings at birth.
• Histopathological examination confirms the diagnosis and involutional changes.

Implications:

• Understanding in utero involution of RICHs refines diagnostic criteria.
• Management strategies for RICHs should consider the possibility of complete prenatal involution.
• This case highlights the importance of recognizing rare presentations of congenital vascular malformations.
