C-cell hyperplasia, abbreviated CCH, is a pathology of the thyroid gland and considered the precursor for medullary thyroid carcinoma.

General

Associated with:

Gross

  • Not visible on gross.

Location:[5]

  • Mid portion of lobe to upper third of lobe.
    • Not at the poles.
    • Not in the isthmus.

Microscopic

Features:

  • Definitions vary.[6]
    • One definition - either of the following:[1]
      1. >50 C-cells per low-power field (x100).
        • This part of the definition suffers from LPFitis.
      2. "Medullary thyroid carcinoma confined to the thyroid gland and no larger than 10 mm in greatest dimension."
    • Another definition:
      • Invasion of the basement membrane with stromal reaction.
    • A third definition:
      • "Several clusters" of more than six C cells.
