A female infant presented at 3 months of age with vascular lesions involving the left lower limb and left side of the vulva. At birth, the left leg was thinner than the right, but equal in length. She had macular, reticulate, bluish discolouration covering most of the skin of the involved leg with superimposed cherry-red papules, most dense over the proximal portion. The macular component showed evidence of improvement within the first few months of life. Papular and nodular components over the leg and the vulva progressively increased in size and thickness until the age of 10 months. These elements had the appearance and behaviour typical of haemangioma of infancy. Regression of these lesions started at the age of 15 months. By the age of 6.5 months, the involved leg was no longer thinner than the right, but the left leg and foot had grown longer. Leg length discrepancy peaked at 2.4 cm at the age of 2 years. The most rapid phase of relative growth discrepancy of left and right leg bones was contemporaneous with the growth phase of the haemangioma. Radiological investigations and histopathology have been consistent with haemangioma of infancy. GLUT-1 immunostaining of the lesion was positive.
