A patient with a history of a displaced mandibular fracture reports pain at the previous fracture site near the mental foramen. On examination, a tender, movable lump is felt in that region. What is the most likely preoperative diagnosis?

Explanation

The presence of a tender, movable mass at the site of a previous mandibular fracture suggests a traumatic neuroma, which is a reactive proliferation of nerve tissue following nerve injury. Neuroleiomyoma and neurofibroma are benign tumors but are less likely in this context. Trigeminal neuralgia presents with sharp facial pain but without a palpable mass.
