Malignant lympho-epithelial lesion--the Manitoba experience.

A retrospective study was carried out utilizing the Records Department of the Health Sciences Centre, St. Boniface General Hospital, and the Manitoba Cancer Treatment and Research Foundation. Seventeen cases of malignant lympho-epithelial lesion were found. The pathology of all cases was reviewed. There were 12 females and five males. Sixteen cases involved the parotid gland and one the submandibular gland. The ages ranged from 17-65 years with the peak incidence in the fourth decade of life. Fifteen of the patients were Eskimos, all residing in the Northwest Territories; two patients were Caucasian. Most patients were treated with a combined modality of surgery with postoperative radiation. The clinical features, pathology, treatment, and final outcome are reviewed.
