This article deals with prostate chips.

Introduction

Prostate chips are generated from transurethral resection of the prostate (TURP) procedures. These are generally for relieving urinary obstruction due to nodular hyperplasia of the prostate (benign prostatic hyperplasia); however, urinary obstruction may be secondary to prostate cancer. Thus, the job of the pathologist here, usually, is excluding an incidental cancer.

The prevalence of prostate cancer is TURP specimens is approximately 17% based on a series of 747 specimens.[1]

Protocol

Specimen:

  • Weight ___ grams.
  • Dimensions (in aggregate): ___ x ___ x ___ cm.
  • Number of fragments: [1-6 / multiple (>6)].
  • Appearance: [tan-gray / yellow / orange].
  • Consistency: [rubbery / firm].
  • Other: [none / hemorrhagic appearance / necrotic appearing].

[Submitted in total/Representative sections submitted] in block(s) ___.

Protocol notes

Number of cassettes:[2]

  • <= 12 grams: EIT.
  • >12 grams: embed 12 grams and 1 cassette for every additional 5 grams.
    • If the prostate chips have a mass of:
      • 16 grams: 6-8 cassettes for 12 grams + 1 cassette = 7-9 cassettes.
      • 21 grams: 6-8 cassettes for 12 grams + 2 cassettes = 7-9 cassettes.

What to look for/feel for:[2]

Entity Colour Firmness
Prostate cancer yellow/orange firm
Benign prostate tan/gray rubbery
