The patient was a 57-year-old man with vision loss in the right eye (OD) greater than left eye (OS) in the setting of a craniopharyngioma, which was resected 16 years prior. His visual acuity had been no light perception OD and 20/20 OS since the procedure.

cutaneous horn, accumulation of keratin
Cutaneous horns are conical accumulations of keratin that can be associated with a variety of benign and malignant lesions including seborrheic keratosis, verruca vulgaris, squamous cell carcinoma, and basal cell carcinoma. Because the responsible lesion underlies the horn, the base of the lesion must be biopsied to ascertain a diagnosis. The lesion in this photo was found to be secondary to verruca vulgaris.
