This case report presents a solid variant of keratocystic odontogenic tumour (KCOT), a benign uni- or multicystic intraosseous tumour of odontogenic origin, with a characteristic lining of parakeratinized stratified squamous epithelium and potential inflammatory infiltrate. A 52-year old female patient discovered occasionally, in an orthopantomography done for other reasons, the presence of a radiolucent lesion. A 2-3 cm wide lesion with well-demarcated margins was present in the premolar region of the left hemimandible. Under local anesthesia a biopsy was done and the diagnosis of odontogenic keratocyst was confirmed by histopathological examination. Under general anesthesia, the lesion was easily shelled-out and completely enucleated. The lesion had not recurred after a 6 years follow-up. The occurrence of a solid variant of KCOT could strengthen the hypothesis of a neoplastic rather than cystic nature of this lesion.
