A midface swelling in a child - A possible diagnostic dilemma.

A lump on the midface of a child can pose as a diagnostic dilemma. There is a wide variety of possible differential diagnoses, ranging from simple benign conditions such as a sebaceous cyst, dermoid cyst, lipoma, neuroma and neurofibroma, to potentially devastating conditions such as odontogenic myxoma. A case of a child in which the formulation of a definite diagnosis was clinically and histologically challenging is presented.
