title: [Leiomyosarcoma of the external ear canal].
abstract: We report on a 45-year-old male patient with the signs of exophytic, obstructive and painless tumour of the right external auditory canal developed within a period of about 3 months. The tumour was completely removed in local anaesthesia and histologically found to be a leiomyosarcoma. The only possible origin of this lesion might be the smooth muscle cells of the local blood vessels or the mm. arrectores pilorum.
