The correct term is KCOT (Keratocystic Odontogenic Tumor), not OKC (Odontogenic Keratocyst).
Understanding the Change from OKC to KCOT
Historically, this lesion was known as Odontogenic Keratocyst (OKC). However, due to its neoplastic nature, demonstrated through clinical behavior and molecular biology, the World Health Organization (WHO) reclassified it in 2005 as Keratocystic Odontogenic Tumor (KCOT). This change reflects a better understanding of the lesion as a true tumor rather than a simple cyst.
Key Points:
- Historical Term: Odontogenic Keratocyst (OKC) was the previous name.
- Reclassification: The World Health Organization changed the name in 2005.
- Current Term: Keratocystic Odontogenic Tumor (KCOT) is the accurate term.
- Reason for Change: Based on its clinical behavior and molecular biology, it's now considered a neoplasm (tumor).
- Reference: The change is supported by the reference [1].
