What is the typical appearance and timeline for strawberry hemangiomas?

Strawberry hemangiomas, also known as infantile hemangiomas, typically exhibit a growth pattern where they initially increase in size rapidly during the first few months of life. This growth phase often peaks around 5 to 6 months of age. Following this period of growth, they gradually undergo a process of involution, during which they reduce in size and eventually resolve. This timeline of growth followed by involution is characteristic of strawberry hemangiomas, which usually become less prominent and can fade significantly or disappear entirely by the time the child reaches school age.

In contrast, other options do not accurately describe the behavior of strawberry hemangiomas. For instance, while it's true that some hemangiomas may remain stable for a period, this is not typical for strawberry hemangiomas, which are noted for their active cycle of growth followed by shrinkage. Furthermore, the assertion that hemangiomas develop only after the first year is not correct, as they commonly present shortly after birth, often within the first few weeks of life.
