A Pilot Study of Intralesional Injection of Triamcinolone Acetonide for Desmoid Tumors

There is research supporting treatment of superficial fibromatoses (palmar fibromatosis and keloids) with triamcinolone acetonide injections. These lesions are histologically similar to deep fibromatoses (desmoid tumors). Currently there is little literature evaluating the response of desmoid tumors to injections of triamcinolone acetonide. The investigators aim to perform a pilot study evaluating the response of desmoid tumors to intralesional triamcinolone. If positive results are observed (based on RECIST criteria), then a phase II study will be initiated.
