Abstract

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.

摘要

目的/方法：报告一例罕见的脉络膜黑素细胞瘤病例。其临床和超声特征与黑色素瘤相似。我们病例中选择的治疗方法是脉络膜切除术。组织用苏木精-伊红染色、过碘酸-希夫染色、马森三色染色，并进行免疫组织化学检查。

结果/结论：脉络膜黑素细胞瘤的临床和组织病理学特征与眼部其他部位的黑素细胞瘤特征相似。在没有组织病理学关联的情况下，脉络膜黑色素瘤和黑素细胞瘤的鉴别诊断非常困难。
