Nodulo-ulcerative ocular surface squamous neoplasia with intraocular tumour extension. a A 56-year-old female presented with right eye nodulo-ulcerative variant of ocular surface squamous neoplasia with scleral thinning, surrounding boggy congested conjunctiva, and overlying keratin. b Anterior segment optical coherence tomography confirmed the nodulo-ulcerative nature of the lesion with scleral infiltration and scleral thinning. c Ultrasound biomicroscopy showed extension of tumour into the ciliary body. d Histopathology revealed well-differentiated squamous cell carcinoma of the conjunctiva with scleral infiltration (Hematoxylin & Eosin (h&e stain); 2× magnification) and e ciliary body infiltration (H&E stain; ×4 magnification) f with dense lymphoplasmacytic infiltration interspersed between the tumour islands (h&e stain; ×4 magnification)
