The description of a 1 ´ 1 cm pedunculated lesion composed of granular cells covered by thin epithelium is characteristic of a congenital granular cell tumor. These tumors are benign and most commonly occur on the gingiva of infants. Peripheral fibromas are composed of fibrous connective tissue, dysplastic oral warts are associated with human papillomavirus infection and display cellular atypia, gingival cysts are lined by thin nonkeratinized epithelium, and neuroectodermal tumors of infancy are highly aggressive malignant tumors.
