Cystic variant of calcifying epithelial odontogenic tumor

Abstract

The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm of the jaw. Clinically, calcifying epithelial odontogenic tumor manifests as an intraosseous lesion (central type) in the majority of cases (95%). Extraosseous or peripheral lesions account for less than 5% of cases. Calcifying epithelial odontogenic tumor can be associated with an impacted tooth and give a radiographic simulation of dentigerous cyst. Most calcifying epithelial odontogenic tumors are solid in nature, histopathologically, and might have few cyst-like spaces within them. However, a true cystic calcifying epithelial odontogenic tumor is a rare possibility. We describe a case of a true cystic variant of calcifying epithelial odontogenic tumor in a 30-year-old male, which to our knowledge, is only the second reported case.

Cystic Variant of Calcifying Epithelial Odontogenic Tumor

“…Additionally, unlike the present case, over 50% of the cases are associated with an impacted tooth, 5,6 including 2 previously published cases of a cystic variant of CEOT. 1,2 Microscopically, the cystic variant of CEOT exhibits cystic lining ranging from focally thin nonkeratinizing stratified squamous epithelium to thickened epithelium with CEOT typical features, 1,2 similar to the current case. Recently, Urias Barrera et al 3 reported a clear cell cystic variant of CEOT.…”

“…Among the histological variants of CEOT, the true cystic variant of CEOT is extremely rare, with only 3 welldocumented cases reported in the English-language literature. [1][2][3] In this report, we describe the clinical, radiographic, and histopathological features of a case of cystic variant of CEOT.A 22-year-old male patient was referred to evaluation of a gingival swelling with approximately 8 months of evolution. Intraoral examination revealed a painless, dome-shaped, nodular lesion, which presented a bluish color and soft/cystic consistency to palpation.…”

“…1 Another indication is the fractured segment is a functional part such as the displacement of the mandibular condyle to the middle cranial fossa which should be absolutely replaced to its anatomical position to gain temporomandibular joint mobility, achieving normal occlusion and lower face height. 2,5 Even in this condition, many authors suggest to use the closed approach including inter maxillary fixation to prevent morbidity of a craniotomy. According to these authors, an intracranial approach is only indicated if the closed approach fails.…”

Cysts and Pseudocysts of the Oral Cavity: Revision of the Literature and a New Proposed Classification

“…Calcifying Odontogenic Cyst (COC). We can distinguish three entities: simple intra-osseous COC, extra-osseous peripheral COC and the malignant form Calcifying Cystic Odontogenic Tumor (CCOT) (21,23,(70)(71)(72)(79)(80)(81). COCs radiologically show a cystic imaging with small scattered areas of calcification, often resembling an odontoma (82).…”
