You can test your knowledge in the L4E rule 4 quiz.

Overview

  • This rule applies to most benign resections.
  • It applies to some small biopsies that are submitted in several blocks, e.g. an endoscopically resected large tubular adenoma of the colon without high-grade dysplasia submitted in 3 blocks.

Details

Specimen type(s) Weight (L4E) Details Examples
Most non-malignant resections (see below) 1 L2/block, 0.33 L4E/block, minimum 1 L3 (0.5 L4E) 1 block = 0.5 L4E, 2 blocks = 0.66 L4E, 3 blocks = 1 L4E, 4 blocks = 1.33 L4E, 5 blocks = 1.66 L4E benign hysterectomy in 12 blocks = 4 L4E, hemithyroid with nodular hyperplasia in 15 blocks = 5 L4E

Note:

  • Rule 5 may apply to cases requiring a synoptic report as per the CAP.

  • Hysterectomy.
  • Thyroidectomy.
