Tarannum Ajaj, Tayyab Sultan Khan, Manish Sharma, Gaganjot Kaur Sharma

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare jaw bone tumor. PIOSCC arises either from epithelial lining of odontogenic cyst or de novo from odontogenic rests. In literature PIOSCC was first described by Loos in 1913 as central epidermoid carcinoma which showed classical features of squamous cell carcinoma but do not arise from surface epithelium primarily. A PIOSCC is difficult to diagnose due to its rare nature and when it do not show classical features of squamous cell carcinoma. Here we present a case where immunohistochemistry plays an important role in the diagnosis of a de novo PIOSCC.
Key words: Primary intraosseous squamous cell carcinoma, Jaw tumor, immunohistochemistry.
