Purpose/Methods:
To report a rare case of melanocytoma in a choroidal location. The clinical and echographic characteristics were similar to those of a melanoma. The treatment selected in our case was a choroidectomy. Tissue was stained with hematoxylin-eosin, periodic acid-Schiff, Masson's trichromic and immunohistochemistry was performed.
Results/Conclusions:
The clinical and histopathologic features of choroidal melanocytoma are similar to the characteristics of a melanocytoma located in other parts of the eye. The differential diagnosis between choroidal melanoma and melanocytoma is very difficult without histopathologic correlation.
