We report the case of an isolated pigmented lesion of the cerebellar t
entorium which was initially interpreted as meningeal melanocytoma. Th
e immunohistochemical study required as a result of a subsequent post-
surgical recurrence prompted us to reconsider the early diagnosis in f
avour of malignant meningeal melanoma. On the basis of data in the lit
erature, the possibility that the lesion may have been a dural melanom
a is discussed.
