Rupture may result in fibrosis, granulation tissue, hemorrhage, and cholesterol cleft formation or cholesterol granuloma.
Epithelial lining of odontogenic keratocysts and cholesterol clefts in the fibrous capsule of radicular cyst are shown in figures 1 and 2 respectively.

Histologically, it is manifested by collection of lipid laden macrophages admixed with mixed inflammatory infiltrate composed of lymphocytes, plasma cells, neutrophils and multinucleated giant cells with or without cholesterol clefts. [12]
