case_images: The orthopantomography which was carried out revealed a 1.5 x 1 cm radiolucent lesion with rough margins located at the body of the mandible at the region distal of 46 in close relation with the mandibular canal [Figure 1]. The extraction of 46 was carried out due to the non-retroverting periodontal infection (large gingival recession of the tooth with more than two-thirds of the root exposed) and serious bone absorption as demonstrated in Figure 1, which made the prognosis of the tooth very poor.

case_images: Microscopically, many foamy histiocytes in dense arrangement and fewer spindle-shaped cells in fascicular and storiform arrangement were observed [Figures 2 and 3].

case_images: Among these cells, small fragments of bone trabeculae were found [Figure 4].
case_images: Orthopantomography 6 months postoperatively. The defect at the area of the surgical site as well as the post-extraction socket of 46 are distinguished. Nothing remarkable concerning the bone healing process is observed

case_images: Clinically, the area of the surgical trauma had healed well and the orthopantomography [Figure 5] showed no signs of pathology at the site of postoperative defect.
