[Facial paralysis caused by compression by a tumor]

Tumors on the course of the 7th nerve are seldom met. Inthe present case the growth caused the palsy and showed, at surgical removal, single apposition to the trunk. Surprisingly on microscopic examination the detached mass disclosed normal striated muscle. The localization in the middle of the vertical portion of the facial canal of such a tumor, so far from other muscular structures, makes this case a rare anomaly.
