Patient 2 corneal and conjunctival tumor

A) Slit lamp photo of left eye from patient 2 showing subtle elevated gelatinous lesion on the cornea (arrow) and conjunctiva consistent with limbal OSSN. B) HR-OCT cut with predicted tumor margin denoted by white arrow. C) Slit lamp photo of left eye showing selected reference landmark (red star). D) OCT en-face reconstruction of ocular surface with reference landmark denoted by red star and measurement to superior HR-OCT predicted tumor margin (white x) from reference landmark with internal calipers E) Examination of the excised conjunctiva discloses faulty epithelial maturational sequencing that extends up to full thickness (carcinoma in situ) with the area of predicted tumor margin (asterisk) adjacent to the transition of unremarkable and dysplastic epithelium. OCT predicted mark (subtle orange pigment, black arrows) coinciding with pathologically identified margin (Hematoxylin-eosin; original magnification x200).
