Experience with desmoid tumor in a community teaching hospital.

Desmoid tumors are rare fibroblastic proliferations that occur primarily in the abdomen and extremities. They have an estimated incidence in the United States of two to four per million inhabitants per year. A recent case of desmoid tumor prompted us to review past medical records for previous cases with the same diagnosis. Since 1985, our institution has treated five patients with a total of eight desmoid tumors. Four patients (80%) were female with ages ranging from 24 to 32 years. The other patient was a 22-year-old male with a history of Gardner's syndrome and recurrent desmoid tumors. The majority of our patients were females in the fertile age group, substantiating the hormonal effects believed to play a role in the development of these lesions. In addition, it became obvious that more investigations must be done in appropriate treatment of desmoid tumors and the documentation of these tumors in registries would be of significant benefit.
