Squamous cell carcinoma arising from an odontogenic keratocyst : a case report
Squamous cell carcinoma (SCC) derived from keratocystic odontogenic tumor is an extremely rare tumor that is limited to the jaws. Most intraosseous carcinomas originate from the epithelial lining of odontogenic cysts, so they are called odontogenic carcinomas. They occur more frequently in men and the mean age of patients is 57 years. The following report describes an extremely rare case of an odontogenic carcinoma derived from a keratocystic odontogenic tumor in a 20-year-old man. The patient presented with an exophytic lesion in the retromolar region of the mandible which was first noticed by the patient 25 days earlier. In panoramic radiograph a well-defined radiolucency around the impac…
The expression of heat shock proteins 27 and 105 in squamous cell carcinoma of the tongue and relationship with clinicopathological index
Introduction: In oral cavity, the tongue is the most common site prone to development of squamous cell carcinoma (SCC). Considering malignant transformation as a cellular stress, the expression of heat shock proteins (HSPs) may be affected in this process. In this study we assessed the expression of HSP105 and HSP27 as two of the most interested stress proteins and investigated their relationship with grade and stage of the tongue SCC. Material and Methods: Fifty-six specimens including 31 early and 25 advanced tongue SCC were gathered. All specimens were graded histologically from I to III. Sixteen sections of normal oral mucosa were used as control group. The cellularity and intensity of …
