Uveal prolapse following cataract extraction simulating melanoma.
Prolapsed uveal tissue through a cataract incision can simulate any pigmented epibulbar mass, including conjunctival melanoma, extraocular extension ofa ciliary body or choroidal melanoma, and pigmented squamous cell carcinoma of the conjunctiva. The authors describe an 88-year-old woman who presented with an enlarging pigmented epibulbar mass on the left eye. Although the lesion closely simulated a conjunctival melanoma or extraocular extension of a uveal melanoma, closer evaluation revealed thin uveal tissue extending through partial wound dehiscence from cataract surgery that was performed 3 years earlier. The lesion was consistent with prolapsed uveal tissue through a cataract wound masquerading as a melanoma. Therefore, uveal prolapse should be considered in the differential diagnosis of conjunctival melanoma or extraocular extension of uveal melanoma.
