What typically happens to a strawberry hemangioma within the first year of life?

Strawberry hemangiomas are a common type of benign vascular tumor seen in infants, particularly in the first year of life. These lesions typically present as raised, red areas on the skin that can vary in size. During the first year, it is common for strawberry hemangiomas to undergo a process known as involution, where they gradually shrink and fade. This spontaneous resolution often begins within a few months after birth and may continue for several years, leading to minimal or no residual changes on the skin.

The process of spontaneous regression is a hallmark characteristic of strawberry hemangiomas, which distinguishes them from other vascular lesions. While they may initially proliferate and appear more prominent shortly after birth, the trend is towards eventual involution. This self-resolution is an important aspect of their behavior and management, as most hemangiomas resolve without the need for medical intervention.

Other potential outcomes, such as remaining unchanged or becoming painful, do not typically occur. Most strawberry hemangiomas do not cause discomfort or any associated symptoms as they regress over time. Thus, recognizing the natural course of these lesions is crucial for healthcare providers when observing and managing infants with strawberry hemangiomas.
