Abstract

We report here the case of an 82-year-old woman who presented with visual disturbance. MRI demonstrated a sellar mass. The diagnosis of pituitary adenoma was made. She underwent transnasal surgery. Histologic, immunohistochemical and ultrastructural studies indicated that the tumor was a melanoma. Despite an exhaustive search for a primary lesion elsewhere, none was found. The sellar tumor was considered a primary lesion, although extrasellar primary tumor imaging cannot be excluded with 100% certainty. Reported examples of melanoma affecting the sellar region are few. They exhibit morphologic features identical to those of melanomas arising elsewhere. Although very rare, primary melanomas enter into the differential diagnosis of sellar lesions.
