  1. Fulltext. Benign soft-tissue tumors in a large referral population : distribution of specific diagnoses by age, sex, and location.

    Article - En anglais



    The purpose of this study was to determine the specific diagnoses, relative prevalence, and the age, sex, and skeletal distribution of benign soft-tissue tumors and to ascertain the relative frequency of these tumors in specific anatomic locations and age groups among a population of patients in a large pathologic consultation service.


    The computer diagnoses of 39,179 lesions occurring in 38,484 patients seen by the Armed Forces Institute of Pathology soft-tissue pathologists during the 10-year period starting January 1,1980, and ending December 31,1989, were retrospectively reviewed.

    All lesions were placed in one of 121 major categories in accordance with the classification system used by the World Health Organization and coded to one of 32 anatomic locations such as hand, wrist, and forearm.

    The study group included 31,047 mesenchymal lesions, of which 18,677 were benign.


    Approximately two thirds of soft-tissue tumors were classified into seven diagnostic categories : lipoma and lipoma variants (16%), fibrous histiocytoma (13%), nodular fasciitis (11%), hemangioma (8%), fibromatosis (7%), neurofibroma (5%), and schwannoma (5%). Approximately 80% of all benign tumors were placed in seven diagnostic categories for each age and location.
