A patient with generalized poorly differentiated lymphoblastic lymphosarcoma of the ileum developed paralysis of the left side of the face. Histologically, the facial nerve was infiltrated and the nerve structure destroyed by the sarcoma from the stylomastoid foramen up to the brain stem, including the stapedial, chorda tympani, and major petrosal nerves. Infiltration of the acoustic and vestibular nerves was less intense and, in some areas, normal nerve bundles were seen. Infiltration was restricted to the major nerves inside their sheath, the sensory organs being involved only to a minor extent. The tumor also spread into the hypotympanum and to the mastoid air cells toward the skull base on the left, and to the air cells close to the major petrosal nerves on both sides.
