[Melanoma of the iris and pregnancy].
Iris melanoma is a malignant melanocytic tumor, making up 1.2%-6.6% of uveal malignant melanomas. The growth of choroidal melanoma during pregnancy is described and a hormonal influence is suggested. We present a case of iris melanoma occurring during pregnancy. A 32-year-old woman, in the 28(th) week of her fifth pregnancy, was referred to the ophthalmologist with a 2-month history of blurred vision and pain in her left eye. The visual symptoms became progressively worse with decreasing vision. Her visual acuity was 20/70 in her left eye, with a temporal, pigmented, prominent iris mass extending into the trabecular meshwork and the corneal endothelium. Elsewhere other pigmented localizations were found in the iris and in the trabecular meshwork. There was secondary glaucoma with intraocular pressure of 36mmHg and C/D=0.9. The right eye was normal. A general physical examination found no pigmented lesions. Chest radiography and hepatic ultrasonography revealed no metastasis. The diagnosis of iris malignant melanoma was made from the diffuse involvement extending into the trabecular meshwork and the advanced secondary glaucoma; an enucleation was performed and histopathological examination confirmed the diagnosis of iris melanoma with involvement of the trabecular meshwork. The patient had no further problems (follow-up of 11 months). From this case report, we discuss the differential diagnosis of iris melanoma and the hormonal influence on its growth.
