“…Pindborg tumor manifests with asymptomatic slow growth in the maxilla or mandible, leading to late diagnosis and local tissue destruction (2,3). Based on the characteristics described in the literature, the present patient was referred for treatment after complaining of a painless volumetric increase in the left posterior mandibular region.…”

“…This lesion represents a benign neoplasm of uncertain origin with no etiological factors described, with probable origin in the enamel organ and oral epithelium (2). In addition, it stands out due to its rarity, accounting for only 0.6% to 1.7% of odontogenic tumors (3). However, it raises concerns because of its local aggressive behavior, leading to formation of large bone defects in the jaw (4).…”

“…Pindborg tumor is typically located in the posterior region of the mandible and it is most often associated with a retained tooth (1,3). Nevertheless, some peripheral or extraosseous locations have been described (4), accounting for 5% of cases (5), and jaw injuries are occasionally reported.…”

“…In general, we recommend enucleation with curettage in small mandibular lesions [3]. Resection with tumor free bone margins of at least 1 cm will be recommend in lesions larger than 4 cm [2], recurrence [5] or involvement of the maxilla, as this location shows a higher growth rate to invade vital structures [2] [3] [16]. Treatment of extraosseous CEOT is also surgical, but could be a simple local excision [2].…”

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.

“…Treatment of a CEOT consists of surgical removal including a marginal portion of apparently healthy bone. A minimum 5-year observation period is suggested [10].…”

ABSTRACT. We report a case of calcifying epithelial odontogenic tumour (CEOT), also known as a Pindborg tumour, with local aggressive behaviour. CT imaging showed a large expansile bone-forming lesion in the mandible, which showed the exact extent and nature of the lesion. We briefly discuss the imaging features of CEOT and the relevant literature. A calcifying epithelial odontogenic tumour (CEOT) is a rare benign odontogenic neoplasm described in 1955 by Pindborg and is now known as a Pindborg tumour. This lesion represents approximately 0.4-3.0% of all odontogenic tumours [1]. To the best of our knowledge, the imaging characteristics of CEOT have been reported in only two cases in the literature [2,3]. We present the CT findings of a CEOT, discuss the contribution of CT to its diagnosis and review the relevant literature. Case reportA 33-year-old female presented with a progressive, painless enlargement of left lower jaw, which she had had for 3 years. A clinical examination revealed a welldefined huge extra-oral bony, hard non-tender swelling involving the left body and angle of the mandible. Intraorally, a well-defined hard, non-tender swelling was seen in buccal vestibule extending from the mandibular left first premolar to the retromolar region with bicortical expansion present. The left lower first molar was missing.An orthopantomograph revealed a large mixed radioopaque-radiolucent lesion in the left body and angle of the mandible with extension into the ramus and with an intact lower border of the mandible. An unerupted first molar was pushed towards the inferior border of mandible. The calcifications were concentrated around the unerupted first molar (Figure 1). CT images were obtained in axial, coronal, sagittal and panoramic views with a three-dimensional (3D) reconstruction. The coronal section revealed a large expansile multilocular and trabeculated lesion involving the left half of the body of the mandible including the level of the ramus and the alveolar margin and was seen extending up to symphysis (Figure 2). The lesion had thinned out and destroyed the mandibular cortices (lingual to buccal) and infiltrated the oral cavity as well as the soft tissue. An impacted unerupted first molar was seen within the lesion (Figure 3). Multiple ossicles and ossific densities with 500-1800 HU were seen throughout the lesion; however, they were more concentrated at the crown of the unerupted first molar. Multidimensional CT reconstructions using hard and soft tissue algorithms demonstrated the size and extent of the lesion, which was essential for surgical planning (Figures 4, 5).Fine needle aspiration cytology was performed and the cytology smear demonstrated features suggestive of a CEOT. A surgical excision was carried out under general anaesthesia and histological analysis confirmed a CEOT. DiscussionA CEOT is a benign neoplasm of unknown cause related to the odontogenic apparatus. It occurs frequently between 30 and 50 years of age with no gender predilection [4]. The tumours are divided according to the...
