Conjunctival malignant melanoma in children.

The first case concerns a 14-year-old girl with a brown conjunctival mass temporally in her right eye which was excised and diagnosed as active conjunctival melanotic lesion. Five years later, a malignant melanoma of the right lacrimal sac and orbit led to general metastatic spread. The second case demonstrates a conjunctival brown mass temporally in the left eye of a 3-year-old boy which enlarged over 4 years. The excision revealed a melanotic lesion which was of uncertain histological dignity. The third case occurred in a 4-year-old boy with a conjunctival glassy tumor temporally in his right eye which after excision led to controversial discussions concerning benign nevus or malignant melanoma.
