Primary Intraosseous Carcinoma of Mandible: A Case Report.

ABSTRACT

Primary intra-osseous squamous cell carcinoma (SCC) is a rare malignant tumor of the jaw. Th is tumor was fi rst labeled by Loos in 1913. It is more common in adults, in six to seven decades of life with predominant location in posterior mandible. We hereby report a case of intraosseous SCC involving the mandible of a 52-year-old male. Th e absence of any defect, proliferative growth or mass intraorally suggested that the origin of the squamous cells was de novo from within the bone. Understanding of the clinical, radiographic, and histopathological features of this tumor allows accurate diagnosis and appropriate treatment of this rare malignancy.
