{Abstract}: BACKGROUND: Pilomatricoma is a common but easily misdiagnosed tumor in children.
OBJECTIVE: To differentiate pilomatricoma from other common subcutaneous nodules in children.
METHODS: Misdiagnosed subcutaneous nodules in four children were recorded.
RESULTS: A red mass on a 7-year-old boy's head which had been misdiagnosed pyogenic granuloma was proved to be pilomatricoma. A red mass on an 8-month-old boy's face which had been misdiagnosed infantile hemangioma also turned to be pilomotricoma. A red mass on a 21-month-old girl's breast, which had been misdiagnosed pilomatricoma, was proved to be infantile myofibroma. A subcutaneous nodule under a 13-month-old girl's armpit, which had been misdiagnosed pilomatricoma, turned to be BCG-associated lymphadenitis.
CONCLUSIONS: When a child with a subcutaneous nodule attends, pilomatricoma, vascular tumors, fibrous tumors, and BCG-associated lymphadenitis should be considered.
