A 38-year-old man presented with a black pigmented fleck of his left upper eyelid. This had been present for 3 years. During 3 years it was gradually increased in size and spread from his upper eyelid to his lower eyelid and bulbar conjunctiva. The biopsies of the eyelid skin and bulbar conjunctiva were performed, and histology confirmed malignant melanoma in situ. Then the lesion was excised with 1.5cm margins and orbital exenteration was performed. Histology showed malignant melanoma 0.4mm thick with no dermal invasion. In this report we discussed surgical management of primary cutaneous malignant melanoma of the eyelid with conjunctival involvement.
