PELAYES, D.E.  and  ZARATE, J.O.. Choroidectomy in choroidal melanocytoma: Clinical and histopathologic characteristics. Arch Soc Esp Oftalmol [online]. 2006, vol.81, n.6, pp.341-344. ISSN 0365-6691.

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.

Keywords : Melanocytoma; choroidectomy; local resection; choroid, immunohistochemistry.
