Extension of Calcifying Epithelial Odontogenic Tumor to the Maxillary Sinus: A Case Report  [PDF]
Mauricio Carrero, Luis Junquera, Juan Carlos de Vicente, Florentino Fresno
Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.45039
Abstract: The calcifying epithelial odontogenic tumor (CEOT) is a rare and benign odontogenic epithelial neoplasm. This tumor accounts for less than 1% of all odontogenic tumors. It normally affects patients between 30 and 50 years old, and it is typically located in the posterior region of the mandible. Involvement of the maxillary sinus has previously been published only in six cases. This report presents a single case of CEOT that invades the maxillary sinus in a 69-year-old male. We performed a left partial maxillectomy and immediate reconstruction of the defect with a temporalis muscle flap. A comprehensive immunohistochemical study was reported. No recurrences have been found after 8 years of follow-up.

Rubio Palau,J.; Bescós Atín,C.; Pamias Romero,J.; Sáez Barba,M.; Raspall Martín,G.; Huguet Redecilla,P.;
Revista Espa?ola de Cirugía Oral y Maxilofacial , 2007, DOI: 10.4321/S1130-05582007000500007
Abstract: the aim of this article is to review the literature on pindborg tumor based on a case. in view of its low frequency and the importance of histology for its correct diagnosis and treatment as it can be confused with other benign tumors, appropriate resection is necessary with tumor-free margins in order to reduce the probability of local recurrence.
Calcifying epithelial odontogenic tumor: Report of two cases
Mandal Shramana,Varma Kachnar,Khurana Nita,Mandal A
Indian Journal of Pathology and Microbiology , 2008,
Abstract: Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign odontogenic tumor. It constitutes 0.4-3% of all odontogenic tumors. There is only a single case, which has been reported in the Indian literature that too in cytology. Microscopically, these are composed of large sheets of epithelial cells, amorphous amyloid-like material and calcification. Although these lesions are benign, they can be locally aggressive, but malignant transformation and metastasis is rare. Considering its locally aggressive nature, appropriate management and long-term follow-up is recommended. We describe two cases of CEOT involving the hard palate and leading to facial alterations.

Brazilian Dental Journal , 2006, DOI: 10.1590/S0103-64402006000200017
Abstract: the calcifying epithelial odontogenic tumor (ceot) is a rare benign odontogenic neoplasm that accounts for approximately 1% of all odontogenic tumors. its origin is controversial as well as its true malignant potential. a case of an advanced ceot associated with an impacted right second molar in the mandible of a young black female patient is presented. computed tomography imaging, radiographic and pathological findings, surgical patterns, gross anatomy of the lesion and the performed treatment are discussed.
The Calcifying Epithelial Odontogenic Tumor (Pindborg Tumor): A Case Report  [PDF]
Mehmet Cemal Akay, Ayhan Tetik, Mert Zeytinoglu
Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1101036
Abstract: Calcifying Epithelial Odontogenic Tumor (CEOT) is a rare benign odontogenic tumor that was first described by Pindborg in 1955. It accounts for less than 1% of all odontogenic neoplasms. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. The radiographic appearance is characterized by uni- or multilocular radiolucent areas with radiopaque masses of varying sizes; there is a frequent association with an unerupted tooth. Most CEOT are intraosseous lesions which are most common in the mandible, with most of these occurring in the molar and premolar regions of the mandible. Malignant transformation and metastasis is rare. ?The aim of the current report was to describe the clinical radiological and histopathological findings in a case of mandibular CEOT.
Intraosseous calcifying epithelial odontogenic tumor in a case with multiple myeloma
Shanmuga Priya,Ravikumar A,Krishnarathnam K,Rajendiran S
Journal of Oral and Maxillofacial Pathology , 2009,
Abstract: Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, is a rare benign odontogenic tumor of locally aggressive behavior. It is more common in the posterior part of the mandible of adults, typically in the fourth to fifth decades. Its origin as well as its true malignant potential is not clearly known. It usually starts as a painless swelling and is often concurrent with an impacted tooth. A case of CEOT in a 55-year-old man with multiple myeloma is presented. Clinical, radiological, and pathologic findings are discussed.
Tumor de Pindborg (tumor odontogénico epitelial calcificante) Pindborg tumor (Calcifying epithelial odontogenic tumor)

Revista Espa?ola de Cirugía Oral y Maxilofacial , 2007,
Abstract: El objetivo del presente artículo es realizar una revisión de la literatura del tumor de Pindborg a propósito de un caso. El interés radica en su baja frecuencia y a la importancia de la anatomía patológica para su diagnóstico y correcto tratamiento ya que puede confundirse en algunos casos con otras tumoraciones benignas, a diferencia de las cuales, en este tumor debe realizarse una resección con márgenes de seguridad para disminuir la probabilidad de recidiva. The aim of this article is to review the literature on Pindborg tumor based on a case. In view of its low frequency and the importance of histology for its correct diagnosis and treatment as it can be confused with other benign tumors, appropriate resection is necessary with tumor-free margins in order to reduce the probability of local recurrence.

Revista Cubana de Estomatolog?-a , 2011,
Abstract: El tumor de Pindborg es una neoplasia benigna, rara, con carácter invasivo local y tendencia a la recidiva, que representa entre el 0,17 y el 1,8 % de todos los tumores odontogénicos, del cual tan solo se han publicado unos 200 casos, con una media de 4 casos nuevos por a o en el mundo. Se presentó el caso de un hombre de 39 a os de edad que acudió a la consulta de cirugía maxilofacial remitido de neurocirugía postraumatismo craneofacial, por presentar un aumento de volumen en el ángulo mandibular derecho. Se tuvo como objetivo publicar la existencia de esta infrecuente neoplasia por lo interesantes que resultan estos tumores por su evolución, dificultad en el diagnóstico, variantes de tratamiento y tendencia a la recidiva. Después de realizar exámenes de laboratorio, radiografías, tomografía axial computarizada y biopsia de fragmento óseo, se obtuvo extensión y diagnóstico de tumor de Pindborg en hemimandíbula derecha. Se realizó la técnica quirúrgica de hemimandibulectomía derecha y reconstrucción con injerto óseo de cresta ilíaca. La evolución del paciente fue satisfactoria.

S Vasudev,VP Singh,R Jhawar,DK Roy
Health Renaissance , 2012, DOI: 10.3126/hren.v10i1.6012
Abstract: Calcifying cystic odontogenic tumor (CCOT) is a unique developmental lesion arising from the odontogenic epithelial remnants present in the jaw bones. It is a very rare lesion having a distinctive histopathologic appearance characterized by the presence of ghost cells with considerable amount of histopathologic diversity. The case report describes a rare and unusually large presentation of CCOT in an 18 year old female. The patient presented with a large swelling in the mandibular’ anterior region. After clinical, radiographic investigations, an incisional biopsy was performed and a diagnosis of CCOT was made. The cyst was enucleated with complete removal of cystic lining. The patient has recovered well and has been kept under observation. DOI: http://dx.doi.org/10.3126/hren.v10i1.6012 HREN 2012; 10(1): 64-68
