case_images: A 32-year-old female patient was referred to a dentist for evaluation of a painful expansion in her mandible [Figure 1].
case_images: Intraoral examination showed a diffuse swelling in the posterior area of left mandible with erythematous and ulcerated overlying mucosa

case_images: The overlying mucosa was erythematous, ulcerated and necrotic [Figure 2].
case_images: Panoramic radiograph of the primary lesion showed a radiolucent lesion with ill-defined borders extending from the left mandibular second premolar to the second molar

case_images: The panoramic radiograph showed a radiolucent lesion with ill-defined borders extending from the second premolar to second molar [Figure 3].
case_images: Histopathologic feature in a low magnification illustrates the nature of the tissue as a mixed odontogenic lesion

case_images: Careful evaluation of slide number 1 showed scattered benign ameloblastic islands and dental papilla-like stroma with tumoral giant cells [Figures 4 and 5].
case_images: Histopathologic section showed scattered odontogenic islands and pleomorphic giant stromal cells in a malignant dental papilla-like connective tissue (x100)

case_images: Hyalinization was seen around these benign islands [Figure 6].
case_images: Some amount of dentinoid material was found near the odontogenic epithelial nests (x100)

case_images: Dentinoid material was also found near some odontogenic epithelial nests [Figure 7].
case_images: Some eosinophilic material was found in the malignant counterpart. The histopathologic feature in these areas was very similar to fibroblastic osteosarcoma (x100)

case_images: Some eosinophilic materials, most likely dysplastic dentin, were also found in this malignant counterpart [Figures 8 and 9].
case_images: The eosinophilic material in sarcomatous area was osteoid like (x400)
