title: Pilomatricoma in a pediatric hospital.
abstract: Of 150 cases of pilomatricoma in Columbus (Ohio) Children's Hospital, nearly 45% were discovered before the age of 5 years and 80% were present by 10 years of age. Lesions involved the periorbital region in 17% of the cases; the upper lid and brow were involved most frequently. These lesions were frequently misdiagnosed: only two of the periorbital cases were correctly diagnosed prior to excisional biopsy.
