This 40 year-old woman
is concerned about the increased pigmentation at the cornea near the
limbus adjacent to an a patch of brown conjunctival lesion. The brown
patch was first noted in her teen but shows no signs of increase in size
or changes in colour. The history and appearance is suggestive of
primary acquired melanosis of the conjunctiva. The increased
pigmentation at the cornea is caused by migration of melanin from the
lesion. She is advised to have an excisional biopsy to look for any
signs of atypia but declined and chooses to have the lesion observed at
6-monthly interval.
