A kidney tumour (renal oncocytoma) at the time of grossing.

Gross pathology, also simply gross, refers to the macroscopic pathology, and the macroscopic assessment of pathology specimens. It may include preparation of tissue for a microscopic examination. It is an essential part of pathologic assessments.

The process of cutting up specimens is known as grossing (North American term), cut-up or macroscopic cut-up (Australian term).

Specimen opening

Usually referred to simply as opening.
May go by the term freshing.
  • The first part of a gross pathologic assessment.

Components

  1. Orient the specimen.
  2. Paint with ink - if applicable.
    • A good general rule is: ink before you think.
  3. Cut open for fixation - if not immediately blocked.
  4. +/-Weigh.
  5. +/-Insert paper towels in the cuts (book marking) for fixation.

Gross only

Gross only specimens are examined only at the grossing bench; no microscopy is done. Which specimens are considered "gross only" typically depends on institutional policy.[1]
