چکیده (انگلیسی):

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant neoplasm that has
an exquisitely exclusive affection to the jawbone. It is defined as squamous cell carcinoma arising
within the jaw and developing from residual odontogenic epithelium or from a preexisting
odontogenic cyst or tumor. The solid-type of this tumor is a central jaw carcinoma arising
de novo and has no initial connection with the oral mucosa. Herein, we report a case of
solid-type PIOSCC involving the mandible in a 37-year-old male patient elucidating its
histopathological and imaging findings. The patient underwent surgical resection followed by
post-operative adjuvant radiotherapy. The close 2-year follow up of the patient revealed
neither locoregional nor distant metastasis.
