Calcifying odontogenic cysts: A novel outlook on classification, diagnosis and management.

BACKGROUND

The Calcifying Odontogenic Cysts (COC) displays a wide range of clinical and histopathological variations as well as diverse biological behaviors. This diversity has led to confusion and disagreement regarding the terminology and classification of this lesion. The previous classification attempts to categorize COC into two concepts. The first concept, termed "monistic," suggests that all COCs are neoplastic despite the majority being cystic in structure and seemingly non-neoplastic. The second concept, known as "dualistic," posits that COC comprises two distinct entities: a cyst and a neoplasm. This research discusses various previous classifications of COC found in the literature and proposes a new, straightforward universal classification based solely on histopathology, aiming to facilitate understanding for surgeons.

MATERIAL AND

METHODS

Fifteen cases of COC have been collected with clinicopathological parameters including detailed information regarding patient demographics, symptoms, anatomical site, radiological characteristics, duration of evolution, recurrence, and types of histopathology according to the proposed classification.

RESULT: A total of fifteen cases of COC were analyzed. According to the histological analysis of the proposed classification Type 1: 5 (33.3), Type II: 4 (26.6), Type III: 3(20), and Type IV:3(20) and recurrence in 3 (20 %) of cases.

CONCLUSION

It simplifies the complexities arising from variations in the cystic linings of type IV of COC, which can be overlooked and have caused recurrence in the current research. Therefore, the key requirement for arriving at a validated and practical conclusion lies in the accurate histological classification of calcifying odontogenic cysts and their impact on treatment.
