Extra-oral examination revealed a 3 x 3 cm swelling on the right posterior of the mandible, extending from posterior to the corner of the mouth over the ramus and angle of the mandible [Figure 1a]. Superioinferiorly, the swelling was extending from retromolar region towards the angle and inferior border of mandible [Figure 1b]. The panoramic view showed erupted first molar and the second molar, displaced inferiorly and anteriorly, lying below the apex of first molar [Figure 1c]. Computed tomography revealed mixed radioluceny and radiodensity and well-defined osteolytic mass involving the right posterior region of the mandible [Figure 1d].
(c) Preoperative panoramic radiograph showing large radioluceny, well-defined sclerotic border along with radiopacity observed in the center of the lesion (Archival), (d) Preoperative computed tomography showing cortical plate expansion, lesion measuring about 4 cms x 5 cms

Considering the factors like intact inferior border, no involvement of adjacent structures, no paresthesia of lip, and age of the patient, this case was planned primarily for excision and curettage without resection [Figure 2a and b].
(a) Surgical excised view, (b) Excised specimen measuring about 4.5 cms x 5.5 cms

Postoperative regular follow-up for 3 years has been done; facial and intra-oral photographs showed normal study [Figure 3a and b]. Panoramic and computed tomography showed osseous regeneration and normal bone pattern [Figure 3c and d].
