We describe a unique case of a de novo desmoid tumor of the posterior media
stinum in a 21-year-old nulligravida. The tumor recurred twice despite its
histologically confirmed radical extirpations. Because of the aggressive lo
cal behavior of desmoid tumors and their unusual locations, which prevent w
ide excision margins, we favor the early consideration of adjuvant therapy.
