Odontogenic Keratocyst with Diverse Variations: A Rare Case Report

RATIONALE: An odontogenic keratocyst (OKC) is a developmental odontogenic cyst lined by squamous epithelium having intrinsic growth potential. Hence, metaplastic changes such as the formation of mucous cells, ciliated cells, and hyaline bodies with ortho/para keratinisation have been known to create unusual histopathological variations. PATIENT CONCERNS: A 34-year-old male patient reported with swelling on the lower right side of the face and numbness on the overlying skin. DIAGNOSIS: Based upon the histopathological findings, a final diagnosis of glandular odontogenic cyst with OKC was confirmed presenting mixed features of basal layer palisading squamous epithelium with goblet cells and satellite cysts appeared to be entrapped in the connective tissue wall. TREATMENT: Surgical enucleation of the cyst was done. OUTCOMES: No recurrence was reported in 1 year of follow-up. TAKE-AWAY LESSONS: Diverse variations appear within odontogenic cysts and tumours. The high recurrence rate and aggressive nature of the cyst, divulges appropriate treatment and long-term follow-up.
