Carcinome in situ conjonctival: une lésion rare à ne pas méconnaitre

We report the case of a 30-year old man, with no particular past medical history, who was seen for corneal lesion of the right eye occurred three months before. Clinical inspection showed protruding lesion in the temporal limbus masking the temporal region of the cornea. This image was confirmed by slit lamp exam. The lesion was finely multi-lobed and had an irregular contour towards the cornea. It encroached on both the cornea and the limbic conjunctiva (Figure A). Visual acuity was 10/10. The remainder of the ophthalmologic examination was normal. Given the clinical aspect evocative of tumoral lesion of the right ocular surface, scheduled surgical resection was recommended. Resection was performed under local anesthesia using an operating microscope allowing complete excision of the lesion. Histological examination confirmed the diagnosis of carcinoma in situ (Figure B). The postoperative course was uneventful. However, patient's evolution was marked by the occurrence of a local recurrence imposing a new surgical procedure six months later.
