(a and b) Extraoral image showing swelling on the right side of the face with reduced mouth opening. (c) OPG shows a well-defined multilocular radiolucency in periapical area of 44, 45, and 46 with scalloped and corticated borders with soap bubble appearance. (d) CBCT in Axial Section shows well-defined hypodense multilocular osteolytic area with corticated structure and scalloped border. (e) CBCT in the sagittal section shows thinning and discontinuity of buccal cortical plate. (f) CBCT in coronal section shows erosion of the superior border of inferior alveolar canal. CBCT: Cone-beam computed tomography

On palpation, swelling was firm in consistency and nontender to touch and afebrile with numbness present [Figure 1a]. Intraoral examination revealed restorations in 43 and 44 [Figure 1b]. Erosion of the superior border of the inferior alveolar canal was appreciated [Figure 1c]. The internal structure was hypodense [Figure 1e] and axial section showed thinning and discontinuity of the buccal cortex [Figure 1d] and coronal section showed erosion on the superior border of the inferior alveolar canal [Figure 1f].
(a) H and E section shows mixed features of the basal layer palisading squamous epithelium with corrugated appearance and resembling reduced enamel epithelium and goblet cells. (b) H and E section shows intraepithelial crypts indicative of glandular epithelium within connective tissue stroma along with entrapped satellite cyst resembling OKC. (c) Surgical enucleation of the cyst. (d) Postoperative OPG on follow-up

Small satellite cysts appeared to be entrapped in the connective tissue wall suggestive of OKC [Figure 2a and b]. The cyst was enucleated and was fixed with Carnoy's solution along with extraction of 44, 45, and 46 [Figure 2c]. The patient was recalled after 1 month and was clinically and radiologically examined [Figure 2d].
