Eruptive syringoma

Eruptive syringoma is a rare variant of syringoma that appears on anterior surfaces of the body, including the neck, chest, and arms. Textbooks state that this eccrine-derived tumor arises at puberty. We describe four cases of eruptive syringoma that began in childhood. We review the literature on this entity and suggest that the disorder typically presents between the ages of 4 and 10 years. Eruptive syringoma is a benign tumor that should be considered among the papular dermatoses of childhood.
