Leiomyosarcoma of the head and neck: a clinicopathological studyAims : The behaviour of leiomyosarcoma is site‐related and there are few data on such tumours located in the head and neck. We studied the clinicopathological features of these lesions. Methods and results : Cases diagnosed as leiomyosarcoma of the head and neck were retrieved from the archives of three institutions. Immunohistochemistry was performed and follow‐up information was obtained. There were seven men and six women, aged 21–73 years, and lesions involved the neck ( n =3), maxilla ( n =4), buccal area ( n =3), and maxillary sinus, nose, and pharynx ( n =1 each). Tumours ranged from 10 to 80 mm. All tumours showed at least focally typical histological features of leiomyosarcoma with perpendicularly arranged fascicles of smooth muscle cells with blunt‐ended nuclei, eosinophilic cytoplasm and paranuclear vacuoles. They expressed muscle‐specific actin (8/9), smooth muscle actin (7/9), and desmin (10/12). Follow‐up information was available on nine patients. All had surgery, with radiation and/or chemotherapy in seven. Three (27%) recurred at 6–24 months; in one case twice. Five (56%) had metastases, including the three with prior recurrences at 1–128 months. Five (including two who received adjuvant therapy) were disease‐free at a median of 47 months, one was alive with metastatic disease at 24 months), and three were dead of disease (median 13 months). Conclusions : Head and neck leiomyosarcomas are rare and aggressive neoplasms which metastasize. Adjuvant therapy has limited effect.
