Also, tooth eight had mobility grade III (Figure 1).
(a) Panoramic view of the lesion: Demonstrates the
radiolucent lesion around the teeth four and five with bone destruction,
(b) CBCT: ill-defined, radiolucent lesion in anterior of maxillary bone,
and palatal perforation.

The lesion resulted to tooth mobility upon displacement. (Figure 2(a)). Cone-beam computed tomography (CBCT) image showed an intrabony, ill-defined radiolucency in anterior region of the maxillary bone with perforation of hard palate (Figure 2(b)) Radiologic differential diagnosis includes inflammatory process due to periodontal lesion of the involved tooth, and odontogenic tumor.
Histopathological view of the lesion; (a)
Non-Specific inflamed connective tissue with prominent histiocyte and
plasma cell infiltration, (b) Scattered area of round eosinophilic
globular structures among the inflamed connective tissue, (c)
Aggregation of Amyloid material, (d) Congo red staining was positive for
amorphous material and showed an dark-green structure under polarized
light.

The histologic examinations correspondingly indicated a fragment of the mucosa with hyperplastic spongiotic stratified squamous epithelium and severely impaired exocytosis in the surface and the adjacent connective tissue, having mixed inflammatory infiltrates and dense collagen bundles (Figure 3(a) and (b)) The foci of scattered, amorphous, and eosinophilic globular structures were also detectable (Figure 3(c)). The Congo red staining was further conducted and amyloid deposits showed an dark green structure, confirming the amyloid material in polarized light microscopic picture (Figure 3(d)).
