Of 973 preterm infants, strawberry hemangioma was recorded in 124 during the first year of life, giving an overall frequency of 12.7%. Male:female ratio was 1:1.4. In 96 infants with birth weight below 1000 g, hemangioma occurred in 22 (22.9%), and in the group of very low-birth-weight infants (below 1500 g) the rate was 15.6%. Ninety-four infants had a single hemangioma and three had more than 10 lesions each. With one exception, no treatment was needed, as spontaneous involution started at age 5 to 12 months.
