(d) 400x, a multinucleated giant cell with a cholesterol cleft (arrow); an early manifestation in the development of cholesterol granulomas.

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.
The lumen was filled with amorphous, eosinophilic material with cholesterol clefts. A thin rim of compressed thyroid tissue was noted outside the fibrous wall.
These sections were studied for the presence of fibrosis, giant cells, granulomas, cholesterol clefts, acute inflammation, and association with adenocarcinomas.
A focal area with cholesterol clefts was also evident.
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]
Histopathology revealed that granulomatous tissue consisted of cholesterol clefts, lymphoplasmacellular infiltrates, marked hemosiderin deposits, and multinucleated foreign body giant cells around cholesterol clefts [Figure 1]e-[Figure 1]g.
The lumen contained eosinophilic homogenous hyalinized material with many cholesterol clefts and red blood cells.
Diagnosis of maxillary sinus CG is based on microscopic analysis of a foreign body reaction characterized by foreign body giant cells and longitudinal cholesterol clefts, granulocytes, foam cells, and macrophages filled with hemosiderin [2, 3].
Cholesterol clefts and foreign body type giant cell reaction was also noted.
