Late recurrence of a primitive neuro-ectodermal tumor.
Late recurrences after therapy are rare in primitive neuro-ectodermal tumor (PNET). Most recurrences occur within the first 2 years after therapy, although a small number of recurrences may occur up to 5 years after therapy. We present a rare case of a recurrence of PNET in a 31-year-old woman 17 years after her initial presentation. The potential biological implications of this late recurrence as well as responses to subsequent therapy, including temozolomide, are discussed.
