  • Reference work entry
  • First Online:
Uropathology

Part of the book series: Encyclopedia of Pathology ((EP))

Definition

Carcinoma with glandular differentiation arising from rete testis.

Clinical Features

  • Incidence

    Rete testis carcinoma is rare.

  • Age

    Age at presentation ranges between 17 and 91 years with a peak around age 70.

  • Sex

    Male.

  • Site

    Carcinoma of the rete testis is centered in the testicular hilum.

  • Treatment

    Orchifunicolectomy.

  • Outcome

    The tumor is aggressive and may have synchronous metastases to para-aortic and iliac lymphnodes. Less commonly metastases to the lungs, liver, and bone have been reported. The prognosis is poor, with an overall 5-years survival rate of 12%. Involvement of the skin of the scrotum, penis, or perineum is reported (Nochomovitz and Orenstein 1984; Michael and Srigley 2013).

Macroscopy

Most patients present with large solid scrotal mass centered in the testicular hilum. The diameter ranges from 1 to 12 cm; size >5 cm is a poor prognostic finding. Many are multifocal and/or extending to the tunica and the spermatic cord. Pathologic reporting supports two main...
