An unusual type of angioma with pain and hyperhidrosis is described. This was first thought to be blue rubber-bleb nevus because of the resemblance of the lesions to blue rubber nipples. While there was no angiomatosis of the gastrointestinal tract, there was pain and hyperhidrosis which are not present in blue rubber-bleb nevus. Sudoriparous angioma combines the interesting features of sweat gland hyperplasia and ectatic blood vessels.
