Peripheral ameloblastoma of the lower molar gingiva: a case report and immunohistochemical study.

چکیده
Peripheral ameloblastoma (PA) is a rare extraosseous odontogenic tumor with histological characteristics similar to those of the common intraosseous ameloblastoma. Two questions regarding PA remain: its histogenic origin and how to differentiate between PA and intraoral basal cell carcinoma. We describe a patient with PA. The result of immunohistochemistry showed cytokeratin (CK) 7-, CK14+, CK19+, AE1/AE3+, CAM5.2-, 34 β E12+, epithelial membrane antigen-, Ber-EP4-, p53-, p63+, and low Ki-67, that was similar to those of 4 cases of intraosseous ameloblastoma. Our results suggest that a PA originates from odontogenic epithelial remnants, rather than from the oral epithelium.

متن کاملPeripheral ameloblastoma of the upper gingiva: Report of a case and literature review
According to the 2005 histological classification of odontogenic neoplasms by the World Health Organization, ameloblastoma is a benign, locally invasive epithelial odontogenic tumor of putative enamel organ origin. There are four distinct subgroups in which this neoplasm can be gathered: the solid/multicystic type, the unicystic type, the desmoplastic and the peripheral type. Peripheral amelobl...
متن کاملMalignant Peripheral Nerve Sheath Tumor in the Maxilla: Report of a Rare Case
Malignant peripheral nerve sheath tumor (MPNST) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. The cell of origin is believed to be the Schwann cell and possibly other nerve sheath cells. In this report, we describe a rare case of MPNST that arise from the socket of second left maxillary molar that has been already extracted in a young man. He was ref...
