Benign Neonatal Hemangiomatosis

Area of Science:

• Pediatric Dermatology
• Neonatal Medicine
• Vascular Anomalies

Background:

• Benign neonatal hemangiomatosis (BNH) is a rare, self-limiting subtype of infantile hemangiomas (IHs).
• BNH is characterized by multiple cutaneous hemangiomas without visceral involvement.
• Other IH subtypes can mimic BNH and pose life-threatening risks.

Purpose of the Study:

• To present a case of benign neonatal hemangiomatosis in a preterm infant.
• To highlight the importance of accurate diagnosis and subtype classification of infantile hemangiomas.

Main Methods:

• A preterm infant presented with multiple generalized cutaneous papules resembling hemangiomas.
• Extensive workup was performed to rule out extracutaneous hemangiomas.
• An observation-only approach was adopted due to the absence of visceral involvement.

Main Results:

• The infant was diagnosed with benign neonatal hemangiomatosis after excluding extracutaneous hemangiomas.
• The hemangiomas increased slightly in size, proportional to the infant's growth, over an 8-month follow-up.
• The patient remained clinically stable throughout the observation period.

Conclusions:

• Early and accurate diagnosis of hemangioma subtypes is critical in neonates.
• Distinguishing BNH from other IHs is essential due to potential life-threatening implications.
• Observation without intervention is appropriate for confirmed cases of BNH without complications.
