Inflamed Dentigerous Cyst: A Case Report and Review

Context: Developmental odontogenic cysts account for 25% of all odontogenic cysts of the jaw. They are commonly associated with impacted or embedded teeth like mandibular/maxillary third molar and maxillary canines. Dentigerous cyst (DC) is a common developmental odontogenic cyst, but its inflammatory variant is quite rare. Settings and design: The representative tissue received was 10% formalin fixed and was 3 × 2 cm in diameter. Materials and methods: Sections of 5 μm thickness were obtained from paraffin-embedded tissues that had been processed and stained with routine hematoxylin and eosin (H&E) stain. These stained sections were then reviewed. Conclusion: Examination of paraffin-embedded sections showed hyperplastic epithelial lining with rete ridges and the connective tissue component with infiltration of chronic inflammatory cells. The treatment of choice for inflamed DC is enucleation, which shows good prognosis.
