This article deals with orchiectomy grossing.

Introduction

Orchiectomies are typically done for testicular tumours.

They may be done for chronic pain or to control prostate cancer.

Specimen opening

  • Orient the specimen - follow cord to hilum and epididymis.
  • Bisect the testis with one cut toward the epididymis.
    • Do not go through.
    • If tumour is a large do additional cuts parallel to the first cut.

Protocol

Dimensions and weight:

  • Laterality: [ left / right ].
  • Weight: ___ grams.
  • Testis: ___ x ___ x ___ cm.
  • Epididymis: ___ x ___ x ___ cm.
  • Spermatic cord - length: __ cm, diameter: ___ cm.
  • Inking: [colour].

Tumour:

  • Size: ___ x ___ x ___ cm.
  • Colour: [ tan / white / variable ].
  • Firmness: [ firm / soft ].
  • Morphology: [solid / cystic / solid and cystic - with ___ % cystic].
  • Circumscription: [circumscribed / infiltrative border ].
  • Hemorrhage: [ absent / present ].
  • Necrosis: [ absent / present ].
  • Extension into tunica albuginea: [ not identified / indeterminate / present ].
  • Extension into the epididymis: [ not identified / indeterminate / present ].

Other - after sectioning:

  • Testicular parenchyma: [ brown-tan, unremarkable / ___ ].
  • Spermatic cord: [ unremarkable / ___ ].

Representative sections are submitted as follow:

  • Spermatic cord resection margin, en face.
  • Spermatic cord mid-section, cross section.
  • Spermatic cord close to testis.
  • Tumour in relation to epididymis.
  • Tumour and rete testis.
  • Tumour with testicular coverings.
  • Additional tumour sections.
  • Testis distant from the tumour.

Protocol notes

  • The tumour should be submitted in total if this can be done in less than 10 cassettes.
  • Lester's book (2nd Ed.) recommends 1 cassette per cm of maximal tumour dimension.[1]

Staging

Based on AJCC 7th Edition:[2][3]

Notes:

  • Invasion into the epididymis and/or tunica albuginea does not change the stage.[3]
  • Rete testis involvement and testicular hilum involvement may be seen or suspected at the time of cut-up. Both of these are poor prognosticators;[4] however, they to do not affect the (AJCC 7th Ed.) stage.
