Schwannoma is usually a solitary, slow-growing, encapsulated benign tumor derived from the Schwann cells with no pathognomic features. Schwannomas are commonly seen in the fourth decade of life. They have a propensity for head-and-neck region. Schwannomas of the oral cavity, more particularly of the upper lip, are very rare. We present an interesting case of schwannoma of upper lip in a pediatric age group associated with a presenting history of trauma, making the diagnosis unexpected. The case is one of the very few reported cases of schwannoma of upper lip and probably one of its kinds associated with a presenting history of trauma. The patient is under clinical control with no signs of recurrence.
