Bilateral non-syndromic dentigerous cyst – Rare case report and literature review

Central odontogenic fibroma, hyperplastic dental follicle, or dentigerous cyst? A diagnostic dilemma: A case report

“…In histopathologic examination of a DC, there is an epithelial lining consists of 2–4 layers of flattened non‐keratinizing cells. 10 In our case, no epithelial lining was seen. Therefore, the diagnosis of a DC was excluded from our differential diagnosis.…”

“…Because the radiolucent space in our case was > 4 mm, it was more likely to be a DC rather than HDF. In histopathologic examination of a DC, there is an epithelial lining consists of 2–4 layers of flattened non‐keratinizing cells 10 . In our case, no epithelial lining was seen.…”

“…Clinically, DCs, HDF, and pericoronal COF can be in the differential diagnosis of each other. 10 Due to its nonspecific histological features, COF may be confused with other odontogenic lesions such as HDF that highlights the importance of clinicopathological correlation in the diagnosis of COF. 5 …”

“…6 Clinically, DCs, HDF, and pericoronal COF can be in the differential diagnosis of each other. 10 Due to its nonspecific histological features, COF may be confused with other odontogenic lesions such as HDF that highlights the F I G U R E 1 Unilocular radiolucency around the crown of impacted maxillary right permanent canine importance of clinicopathological correlation in the diagnosis of COF. 5 Radiographic distinction between a small DC and an HDF around the crown of an unerupted tooth is difficult.…”

“…Small islands or cords of inactive odontogenic epithelium may be present in the fibrous wall. Because a thin layer of REE normally lines the DF surrounding the crown of an unerupted tooth, it can be difficult to distinguish a small DC from simply a normal DF or HDF based on microscopic features alone 10 …”
