Infantile hemangiomas are reported in 10-12% of children less than 1 year of age, with ulceration in about 5-13% of cases. Little is known about the mechanism of this disease and explanations are still being looked for. We present a 4-month-old female infant with haemangioma on the left buttock; the hemangioma was noticed at 2 weeks of age, progressively enlarging and ulcerated.
