Rushton bodies were seen within the epithelial lining.
These Rushton bodies were positive with Papanicolaou (PAP) & Masson's Trichrome stains.
In some cases of radicular cysts cholesterol clefts, Rushton bodies and pulse/seed granulomas are occasionally seen.
Rushton bodies within the epithelium in odontogenic cyst were first described in detail by MA Rushton and hence are often referred to as Rushton bodies.
Microscopically, on histopathological examination Rushton bodies appear as structures tucked within the epithelium that are acellular, eosinophilic, linear, straight or curved or hairpin shaped, circular or polycyclic forms often with a granular core and at times laminated concentrically.
Rushton bodies give negative result with Periodic acid Schiff and Von Kossa's stains for mucopolysaccharides and calcium respectively.
According to Rushton, Rushton bodies originated from odontogenic epithelium as a keratin product.
In our case, Rushton bodies within the epithelial lining appeared as acellular, eosinophilic and curvilinear shaped structures.
This paper represents a case of radicular cyst showing Rushton bodies which is very rare and the clinical significance of Rushton bodies is still not clear in the present scenario.
