Solid variant of odontogenic keratocyst in a 22-year-old man: Report of a case.

KEY CLINICAL MESSAGE: In conclusion, we can focus on histologic features such as stellate reticulum, reverse polarization of basal cell layer nuclei, and luminal lamellated keratinization as distinguishing factors of ameloblastoma and SKCO. If there is any clinically doubt, molecular testing could be helpful.
