Capillary haemangioma of infancy, bright, red, nodular lesions with a smooth surface on the nose, chin, and neck in a child aged 4 months.
Infantile hemangiomas are benign vascular neoplasms that have a characteristic clinical course marked by early proliferation and followed by spontaneous involution. During the proliferative phase in the neonatal period or early infancy, a rapidly dividing endothelial cell proliferation is responsible for the enlargement of infantile hemangiomas. Finally, an involutional phase occurs, whereby most infantile hemangiomas are clinically resolved by age 9 years.
Same patient aged 5 years. There has been a virtually complete spontaneous regression with no scarring on the nose and very slight scarring on the right portion of the lip and chin.
Hemangiomas are the most common tumors of infancy, and most infantile hemangiomas are medically insignificant. Occasionally infantile hemangiomas may impinge on vital structures, ulcerate, bleed, cause high-output cardiac failure or significant structural abnormalities or disfigurement. Rarely, a cutaneous infantile hemangioma may be associated with one or more underlying congenital anomalies.
