Dr. Sonal Shah (Dental Medicine) and Drs. Bill Montagne, Spencer Muscelli, Joshua Goldman, and Jo-Lawrence Bigcas (all Medicine; Otolaryngology; Head and Neck Surgery) co-authored and presented the poster, “Primary Intraosseous Carcinoma of the Mandible Originally Diagnosed as Squamous Cell Carcinoma of Unknown Primary: Case Report,” during the American Head and Neck Cancer Society annual meeting in Montreal, Quebec. Primary Intraosseous Carcinoma, a rare tumor, is defined as a squamous cell carcinoma arising within the jawbone, but its diagnosis requires ruling out other primaries and confirming the lack of mucosal ulcerations and changes.
