case_images: Intraoral examination revealed 3 x 2 cm, irregular-shaped firm mass at palatal gingiva of the right maxillary extending to the midpalate area (A). The maxilla after reconstruction with buccal fat pad and buccal flap advancement (B). The maxilla after 2-year follow-up showed complete mucosalization without scar contraction (C).

case_images: Intraoral examination showed an irregular-shaped firm mass at the palatal gingiva of the right third maxillary molar extending to the midpalate area, sized 3 x 2 cm (Figure 1(A)). Then, the maxillary defect was reconstructed with buccal flap advancement and buccal fat pad (Figure 1(B)). A two-year follow-up showed no signs of recurrence (Figure 1(C)).
case_images: Panoramic radiograph shows no sign of intrabony tumor (A). Periapical radiograph shows generalized vertical bone resorption suspected due to chronic periodontitis and furcation involvement at right maxillary molar teeth (B).

case_images: Panoramic and periapical radiographs show vertical bone loss with furcation involvement at the right maxillary molar teeth, suspected as a result of periodontitis (Figures 2(A) and 2(B)).
case_images: Histopathologic features show irregular-shaped islands of malignant ameloblastic epithelial cells with cellular crowding (A). Malignant spindle cells arrange in streaming fascicles whereas a few stellate reticulum-like cells are observed in small foci. The tumor cells demonstrate cytological atypia (B).

case_images: The histopathological features were consistent with peripheral ameloblastic carcinoma with the positive margins (Figures 3(A) and 3(B)).
case_images: Coronal section of bone window medical computed tomography image shows no sign of bony invasion (A). Sagittal section of bone window medical computed tomography image shows no sign of bony invasion (B).
