A Case of Conjunctival Malignant Melanoma with Extensive Corneal Displacement

ABSTRACT

PURPOSE: To report a patient with malignant conjunctival melanoma with extensive corneal invasive growth. METHODS: A 63-year-old woman with 9 x 7 mm sized dark brown colored conjunctival mass with extensive corneal invasive growth over a 3-month history was seen. The mass was removed and biopsy was done. Fontana-Masson, S-100 protein, and HMB stainings were used to confirm the diagnosis of malignant melanoma. RESULTS: The tumor was easily separated from the corneal surface and adjacent conjunctiva was excised. Fontana-Masson, S-100 protein, and HMB stainings revealed corneally-displaced malignant conjunctival melanoma. There was no evidence of metastasis. CONCLUSIONS: Corneally displaced malignant conjunctival melanoma was very rare. A good surgical result was obtained with its removal.
