Overview
Non-involuting congenital hemangioma (NICH) is a benign vascular tumor of infancy characterized by persistent growth and lack of spontaneous regression, distinguishing it from rapidly involuting congenital hemangiomas 1.Diagnosis
Imaging: Ultrasound and MRI are crucial for diagnosis, identifying characteristic features 1.
Maternal Serum Markers: Elevated maternal serum alphafetoprotein levels may be associated but are not diagnostic 1.
Histopathology: Definitive diagnosis often requires biopsy, showing typical vascular proliferation 1.Management
Observation: Many NICHs require no specific treatment and can be monitored clinically 1.
Intervention: Indicated for complications such as ulceration, bleeding, or significant cosmetic concerns 1.
Medications: Specific drug classes and doses for NICH are not detailed in the provided abstracts 1.Special Populations
Pregnancy: Antenatal diagnosis possible via sonography; associated placental anomalies like chorioangioma may elevate maternal serum markers 1.Key Recommendations
Antenatally detected placental anomalies associated with elevated maternal serum alphafetoprotein levels should prompt careful monitoring for potential NICH 1 (Evidence: Expert opinion).
Ultrasound and MRI are essential diagnostic tools for confirming NICH in infants 1 (Evidence: Moderate).
Treatment decisions should be individualized based on clinical symptoms and complications rather than size alone 1 (Evidence: Expert opinion).References
