Conjunctival melanoma after excision of a lentigo maligna melanoma in the ipsilateral eyelid skin.

Figure 3 Atypical acquired melanosis, shown by clusters ofabnormal melanocytes in the epithelium, migrating awayfrom the basement membrane. Squamous metaplasia ofthe epithelium, with loss ofgoblet cells, is also seen. Haematoxylin and eosin. Magnifcation x300. We present an unusual case in which conjunctival melanoma was preceded by excision of a lentigo maligna melanoma ofthe ipsilateral lower eyelid skin, and in which melanosis secondarily spread back into the grafted eyelid skin.
