hemangioma
Pronunciation: he-man-jee-OH-ma
A benign vascular tumor that appears as a bright red, raised lesion, most commonly occurring in infants during the first year of life.
Full Definition
Hemangiomas are the most common vascular tumors of infancy, affecting approximately 10% of infants. They typically appear within the first few weeks of life, grow rapidly during the first year, and then slowly involute over several years. In medical documentation, the location, size, and growth phase must be carefully recorded. These lesions can be superficial, deep, or mixed, and may require intervention if they interfere with vital functions or cause significant cosmetic concerns.
Usage
Usage note: Distinguish from other vascular malformations; specify anatomical location and growth phase.
