RESUMEN
A 58-year-old woman presented with a 30-day history of a moderately painful enlarging nodule on her upper cutaneous lip. Two weeks prior to presentation, she fell on the sidewalk leading to injuries of the oral mucosa, right temple, and knees. Physical examination revealed a 1.3-cm erythematous crusty nodule on the upper cutaneous lip and vermillion border resembling a keratoacanthoma-type squamous cell carcinoma. With gentle compression, a tooth was expressed from the wound. Dental traumas are usually associated with damage to the surrounding tissues, varying from bruises to deep lacerations. Potential complications include abscess formation and neurovascular damage. Tooth fragments, if undetected at the time of trauma, may remain undiagnosed for longer periods, leading to infection and disfiguring fibrosis.
