Patients with squamous cell carcinoma of unknown primary (SCCUP) typically present with an enlarging neck mass found on biopsy but with no indication of primary site on diagnostic exams such as flexible laryngoscopy, CT, MRI, and\/or PET\/CT. Failure to identify primary sites eliminates surgical treatment as an option, pushing patients toward definitive chemoradiation with associated side effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Indocyanine green (ICG) has been used to identify primary carcinoma in known oropharyngeal squamous cell carcinoma while using transoral robotic surgery (TORS). In this case, we injected ICG intraoperatively in a patient with SCCUP to help with the real\u2010time localization of ICG in the tumor.<\/jats:p>\n                  <\/jats:sec>\n
