ABSTRACT
INTRODUCTION:
Cutaneous malignant melanomas rarely occur in the eye, usually in the eyelids or the conjunctiva. Conjunctival malignant melanomas are even rarer. Most melanomas are dark in color as they are pigmented. However, amelanotic conjunctival malignant melanomas, a scarce variant of the cancer, can be challenging to diagnose accurately. CASE PRESENTATION We present two cases of white Caucasian Swedish-born women who were diagnosed with unilateral amelanotic malignant melanoma in the conjunctiva of the eye. In the first case, the patient was an 81-year-old woman who was suffering from redness and foreign body sensation in the left eye. The initial diagnosis was blepharitis. Three biopsies were taken, which showed malignant melanoma in the eyelid and the conjunctiva. Unfortunately, the eye and the rest of the orbit could not be saved, and the patient had to undergo an orbital exenteration. In the second case, the patient was a 50-year-old woman, and the tumor was localized in the temporal conjunctiva of the left eye. The initial diagnosis was pinguecula, but at the time of surgery, the physician suspected conjunctival intraepithelial neoplasia. The tumor was not completely removed, so adjuvant brachytherapy and local chemotherapy were used. The eye was preserved. No neck and/or lung metastasis was detected in either case at the time of diagnosis.CONCLUSIONS:
Conjunctival amelanotic malignant melanomas should be suspected when tumors are present in the eye and/or the eyelids. By suspecting amelanotic malignant melanoma, the delay in treatment can be shortened. Treating them as soon as possible is essential to minimize the risk of metastasis.Key words
