[Mitomycin C in treatment of conjunctival melanoma and primary acquired melanosis].

BACKGROUND

Since 1995 we have used Mitomycin C additionally in the treatment of conjunctival melanoma and primary acquired melanosis.

METHODS

We report on the therapy results of 14 patients suffering from pigmented conjunctival lesions (malignant melanoma 9 and primary acquired melanosis 5). After local excision, cryotherapy or irradiation all patients received one eye drop Mitomycin C (0.02%) four times daily for four to six weeks.

RESULTS

We observed regression of the pigmentations in 11 cases after median follow up of 13.1 months. In one patient there was no change. Two cases showed progression with tumefaction. There were no adverse reactions except conjunctival hyperemia during therapy.

CONCLUSIONS

Topical administration of Mitomycin C may be useful in the treatment of pigmented conjunctival lesions. Longer follow-up periods are necessary.
