Confronting the Unseen: A Journey Through Primary Intra-orbital Squamous Cell Carcinoma.

ABSTRACT

Cases of squamous cell carcinoma (SCC) that are primary in origin occur even more infrequently due to the lack of squamous epithelium that is typically present in the orbital region. When SCC occurs in the orbit, it is more commonly due to invasion or metastasis from a local site. We report an uncommon case of intra-orbital SCC in a 74-year-old male, which is likely of primary origin. Brain, face, orbital, and neck magnetic resonance imaging proceeded to gather more information on the extent of the patient's orbital malignancy, which showed significant orbital burden and intracranial extension. The biopsy was performed with final pathology results showing moderately differentiated SCC. The patient was discharged with a follow-up with oncology for chemotherapy and a follow-up with oculoplastics for surgical intervention in nine months, after completing a course of chemotherapy with irradiation. We provide this case to shed insight into the difficulties associated with the extremely uncommon occurrence of primary SCC of the orbit.
