Pigmented Pindborg tumor of the maxilla: A case report
نویسندگان
چکیده
The calcifying epithelial odontogenic tumor (CEOT), also known as the Pindborg tumor, is a benign locally invasive neoplasm. Common variants of CEOT include noncalcifying, Langerhans cell, bone and cementum forming and clear cell, which have a prognostic significance. Pigmented variants are known to occur in other odontogenic tumors. However, a definitive pigmented variant of CEOT has not been reported in literature so far. Here, we report the first case of pigmented Pindborg tumor arising from the maxilla in a young female. The pigment was demonstrated as melanin by staining and confirmed by immunohistochemistry. The pigmented variant of CEOT did not recur within 18 months postsurgery. Our report indicates that it is essential to recognize the pigmented variant. We discuss the common variants of CEOT and potential histogenesis of the pigmented variant. Further studies are required to reveal the histogenesis of melanocytes and their pathological significance in the odontogenic tumors.

BACKGROUND AND AIM: The calcifying epithelial odontogenic tumor (CEOT) is a rare entity described by Pindborg and represents < 1% of all odontogenic tumors. Nearly 200 cases of this neoplasm have been reported to date. It mostly occurs in the posterior mandible associated with an impacted tooth, most often a mandibular molar. Patients are usually between 30 and 50 years of age, with no sex pred...

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...
