Graves' disease
Diagnosis in short

Graves' disease. H&E stain. (WC)

LM hypercellular appearance with patchy lymphocytes, little colloid that is scalloped, +/-nuclear clearing, +/-papillae
LM DDx papillary thyroid carcinoma
Gross "beefy-red" appearance, enlarged
Site thyroid gland

Associated Dx papillary thyroid carcinoma
Signs exophthalmos
Prevalence uncommon
Blood work TSH-receptor antibody - required

Graves' disease, also Graves disease, is an autoimmune disease that leads to hyperthyroidism.

It is often misspelled "Grave's disease".

General

Clinical:

  • TSH-receptor antibody +ve.[2]
  • +/-Exophthalmos (bulging eyes).

Hyperthyroidism

Mnemonic hyperTHYROIDISM:[3][4]

  • Tremor.
  • Heart rate elevated, palpitations.
  • Yawn (fatigue).
  • Restlessness.
  • Oligomenorrhea, amenorrhea.
  • Intolerance to heat.
  • Diarrhea.
  • Irritable.
  • Sweating.
  • Muscle wasting/weight loss.

Gross

Features:[5]

  • Enlarged 50-150 g.
  • "Beefy-red" appearance, looks like raw beef.

Microscopic

Features:

  • Classic:
    • Hypercellular
    • Patchy lymphocytes.
    • Little colloid.
  • Scalloping of colloid; colloid has undulating border.
    • Non-specific finding.
  • +/-Nuclear clearing.
  • +/-Papillae (may mimic papillary thyroid carcinoma in this respect).

Notes:

  • Usually has an unimpressive appearance... as it is treated, i.e. history is important.
  • Nuclear clearing and papillae are usu. diffuse in Graves' disease - unlike in papillary thyroid carcinoma.
