Leiomyosarcoma of the external ear--case report.

In head and neck region leiomyosarcoma is a very rare finding. This tumor is usually located in abdominal cavity. We report a case of 78-year-old man with tumor of the auricle that was resected with 0.7 cm margin. Histological and immunohistochemical analysis revealed the leiomyosarcoma. Adjuvant therapy was not advised. During 3 years of follow-up there are no signs of recurrence. Review of the literature shows that the survival of patients with leiomyosarcoma in head and neck region seems to be similar to other kinds of sarcomas in this localization. It is not clear, how large surgical margins should be to achieve satisfactory local control.
