A 1-year-old girl developed a lesion in the skin of the right forearm. The lesion slowly increased in size and was removed when the girl was 6 years old. On removal the lesion was circumscribed, partially encapsulated, and was composed of wavy fibrils, cells with serpentine nuclei, and numerous large round to oval ganglion cells. The patient has no other tumors at this time, but had multiple papular lesions of the feet at birth, which spontaneously regressed before the age of 1 year. The exact nature of these lesions was not determined.
