CASE REPORT A 65-year-old male, referred for minimal otalgia and “pressure” sensations in the area of the left jaw, presented with a 25-mm-diameter radiolucent lesion located in a pericoronal relationship surrounding the crown of the impacted left mandibular third molar (Fig. 1). His medical history was significant for hypertension and hypercholesterolemia, for which he was taking bisoprolol, Lipitor, and acetylsalicylic acid. Radiographically, the lesion appeared to be unilocular and extended into the ascending ramus. Its margins were mostly well circumscribed, although a localized area of irregular bone destruction with indistinct margins was noted along the superior margin. The borders of the anterior margin were distinct. The posterior margin appeared to extend to the anterosuperior aspect of the inferior alveolar canal. No bony expansion was noted. The lesion was of unknown duration.
