Desmoplastic small round cell tumor (DSRCT) is a high-grade aggressive round cell tumor of uncertain histogenesis, associated with prominent stromal desmoplasia and polyphenotypic differentiation.

Clinical Features

  • Incidence

    Paratesticular DSRCT is very rare with approximately 20 such cases reported in the literature.

  • Age

    Like DSRCT at other sites, it is seen in older adolescents and young adults.

  • Treatment

    Surgical resection, often with orchiectomy, is the preferred local treatment. Radiotherapy may also be used. Chemotherapy is part of the standard therapy, both in the neoadjuvant and adjuvant setting.

  • Outcome

    The overall survival is poor, ranging between 15% and 30% at 5 years. However, tumors in the paratesticular location have a better survival, possibly because they are detected earlier and they are more amenable to complete surgical resection.
