It was initially described by Padayachee and van Wyk in 1987, who called it ‘Sialo-Odontogenic Cyst’ due to the presence of mucous cells and pools of mucin in the epithelial lining, and the fact that mucous pools are often lined by eosinophilic cuboidal cells which resemble salivary gland ducts [1]. Here, MUC5AC is linked to cyst.
