BACKGROUND: Sinonasal squamous cell carcinoma is a rare, rapidly progressing malignant tumor of the nasal sinuses. Symptoms include unilateral nasal obstruction and nose bleeding. Orbital invasion signifies advanced disease, and presents as proptosis, pain, chemosis, and decreased ocular motility. Treatment consists of combined modalities, including surgical excision, chemotherapy, and radiation therapy. Advanced inoperable tumors treated with radiation alone have a 5-year survival rate of less than 20%.
CASE REPORT(S). A 68 year old white male presented to the eye clinic complaining of decreased vision accompanied by redness, pain, and tenderness OS that had worsened for one month. He had a history of allergic rhinitis and nasal polyps, and was symptomatic for nasal obstruction and nose bleeding. He was also a non-insulin dependent diabetic. Distance visual acuities were 20/25 OD and 2/400 CONCLUSIONS. Sinonasal neoplasm comprises less than 1% of all malignancies. Advanced disease may present with ocular manifestations; hence, it is crucial to properly diagnose and co-manage to prevent delays in treatment. This patient is currently undergoing radiation therapy, which will involve the left eye. He is being monitored for ocular complications secondary to the radiation therapy.
