ABSTRACT
The calcifying epithelial odontogenic tumor is a rare benign neoplasm that accounts for approximately 1% of all odontogenic tumors. Most of the cases occur in the posterior mandible, and a few involve the maxilla. Despite their relatively indolent biological behavior, tumors in the maxilla tend to grow fast. We report the case of a 33-year-old female patient exhibiting swelling in the right maxilla. An isodense area associated with an impacted supernumerary tooth was found on imaging examination. The histopathologic diagnosis was a calcifying epithelial odontogenic tumor. The treatment of choice was surgical removal of the lesion and associated dental elements. The patient has been followed up for 11 months and shows no signs of recurrence. Besides describing this case, we reviewed the literature on the association of calcifying epithelial odontogenic tumors with supernumerary teeth and found two case reports addressing this subject.

RESUMEN: El Tumor Odontogénico Epitelial Calcificante (TOEC), también denominado Tumor de Pindborg, se define como una neoplasia benigna, caracterizada por la proliferación epitelial; presenta secreción de una proteína tipo amiloide con tendencia a la calcificación. Representa menos del 1% de los tumores odontogénicos. Reportamos un caso en paciente de 75 años con un TOEC en la región maxilar izquierda en relación a una pieza dentaria incluida. El caso no mostró sintomatología específica, sólo una expansión de corticales vestibular y palatina. El diagnóstico se confirmó histológicamente mediante biopsia incisional y extirpación quirúrgica de la lesión, mostrando una histomorfología clásica para este tipo de lesiones. Reportamos este caso para resaltar la edad de presentación inusual, especialmente su localización e ilustrar su abordaje terapéutico y seguimiento.
ABSTRACT: The Calcifying Epithelial Odontogenic Tumor (CEOT), also called Pindborg Tumor, is defined as a benign neoplasm, characterized by epithelial proliferation; secretion of an amyloid-like protein is present with a tendency to calcification. It represents less than 1% of odontogenic tumors. We report a case of a 75-year-old patient with a TOEC in the left maxillary region in relation to an included tooth. The case did not show specific symptomatology, only an expansion of vestibular and palatal corticals. The diagnosis was confirmed histologically by incisional biopsy and surgical removal of the lesion, showing a classic histomorphology for this type of lesions. We report this case to highlight the unusual age of presentation, especially its location and to illustrate its therapeutic approach and follow-up.

El tumor odontogénico epitelial calcificante o tumor de Pindborg es una neoplasia odontogénica benigna y poco frecuente que afecta predominantemente la mandíbula. El objetivo de este trabajo fue reportar y discutir un caso clínico de una mujer de 65 años de edad que presentaba un tumor de Pindborg en la zona de sínfisis mentoniana. El diagnóstico presuntivo se realizó según los hallazgos clínicos y radiográficos. Se efectuó una biopsia incisional que confirmó el diagnóstico. El tratamiento se basó en la resección completa de la masa tumoral con legrado óseo quirúrgico periférico. Para la prevención de la fractura patológica, se colocó una placa de reconstrucción y relleno óseo en la lodge posquirúrgica. A pesar del porcentaje de recidiva en casos reportados en la literatura, el tratamiento fue conservador y el control a distancia después de 6 años fue favorable (AU)
The calcifying epithelial odontogenic tumor (CEOT) or Pindborg tumor, is a rare benign but locally aggressive odontogenic neoplasm that affects the jaw. We report and discuss a case of a 65-year-old woman who presented a Pindborg tumor located in the mandibular symphysis region. The presumptive diagnosis was carried out by means of clinical and radiologic findings. The diagnosis was confirmed by the histological examination. Then, a resection of the entire mass was done, with osseous curettage. Reconstruction was achieved using a reconstruction plate system and bone void filler. Because of the risk of recurrence, the patient was followed closely. At the last follow-up examination 6 years after treatment the panoramic radiograph demonstrated that the cavity was almost completely ossified without any sign of CEOT recurrence (AU)

Odontogenic tumors constitute a wide spectrum of lesions ranging from malignant and benign neoplasms to dental hamartomas, all derived from the epithelial and ectomesenchymal remnants of the tooth forming apparatus. Calcifying epithelial odontogenic tumor (CEOT) is an uncommon, benign epithelial odontogenic tumor first described by Pindborg in 1956. It is a universally accepted eponym for this neoplasm. Pindborg tumor or CEOT is a locally aggressive neoplasm that accounts for 1% of the total odontogenic tumors, with recurrence in 14% of cases. The etiology of this tumor remains an enigma to the clinician. Pindborg suggested that the tumor arises from the remnants of reduced enamel epithelium of an unerupted tooth. Recent studies in literature report that the tumor arises from stratum intermedium. We report a case of Pindborg tumor in a 22-year-old male patient in the left mandibular posterior region. Radiographically, a well-defined radiolucency was associated with unerupted mandibular second molar which was displaced to the inferior border of the mandible. Along with routine haematoxylin and eosin stains, this case reports histopathological findings using Congo red stain and modified Gallegos stain.
ABSTRACT
Treatment of patients with maxillofacial defects is one of the most challenging tasks. Prosthetic reconstruction of maxillomandibular defects may be achieved with the help of removable and fixed prosthesis to restore the lost form, function and speech. The purpose of this article is to describes a case of CEOT (Calcifying Epithelial Odontogenic Tumor) in left mandibular body region managed with a treatment obturator, which allowed closure of the defect by secondary healing through granulation tissue maturation and associated bone fill. A 19 guage wire was used to stabilize the appliance, and provide retentive properties. The obturator allowed decrease in size of defect and enhanced comfort and overall wellbeing of the patient.
ABSTRACT
A calcifying epithelial odontogenic tumor (CEOT) was first described as a separate entity in 1955 by Pindborg, and has since been referred to as Pindborg tumor. CEOT is characterized by the presence of squamous-cell proliferation, calcification and amyloid deposits, and accounts for only 1% of all odontogenic tumors. CEOT is a benign, though occasional locally invasive, slow-growing neoplasm. It is located either intraosseously or extraosseously, and is usually associated with an unerupted permanent tooth. A 24 year-old female visited our clinic, presenting with a palatal swelling and intra-oral ulcer. After an incisional biopsy, the lesion was confirmed to be odontogenic tumor. A tumor resection and reconstruction surgery with tongue flap were performed.

Odontogenic tumors constitute a group of heterogeneous disease derived from epithelial, mesenchymal and/or ectomesenchymal elements. Ameloblastoma is the best known and the most frequent form of odontogenic tumors. Calcifying epithelial odontogenic tumor (CEOT), known as Pindborg tumor, is locally invasive lesion which has a characteristic amiloid deposition. Here a case of a peripheral ameloblastoma associated with CEOT is presented with clinical and morphological features.
ABSTRACT
Pindborg tumor occurs rarely, with a frequency ranging from 0.17% to 1.8% of all odontogenic tumor. It typically presents as a painless asymptomatic expansile mass, but it can result in mechanical effects. The treatment of Pindborg tumor in the past has varied, ranging from enucleation or curettage, to hemimandiblectomy or hemimaxillectomy. We experienced a case of Pindborg tumor treated by marsupialization with sufficient results. But since recurrence has been reported from 10% to 14%, we plan on close observation over at least 5 years.
