Invasive Ocular Surface Squamous Neoplasia Masquerading as Nodular Scleritis.

The authors report a rare case of ocular surface squamous neoplasia with intraocular involvement that had an initial masquerade presentation of recurrent anterior nodular scleritis. A 35-year-old male patient presented with right eye recurrent anterior nodular scleritis for which a lamellar patch graft was done. Two months later, the patient presented with recurrence of symptoms. Histopathology review revealed the presence of well-differentiated squamous cell malignancy. A high index of suspicion for malignancy is required in such cases when they do not respond to conventional therapy.
