Summary
Subacute thyroiditis can mimic thyroid cancer, especially when nodular enlargement is present. Persistent nodules require thorough investigation to rule out malignancy.
Area of Science:
- Endocrinology
- Oncology
Background:
- Subacute thyroiditis (De Quervain's thyroiditis) is an inflammatory condition of the thyroid gland.
- It typically presents with fatigue, neck pain, and thyrotoxic symptoms, often diagnosed via elevated erythrocyte sedimentation rate and low radioiodine uptake.
Observation:
- Four women presented with symptoms suggestive of subacute thyroiditis.
- Two patients with painful, enlarged thyroids initially diagnosed with subacute thyroiditis were later found to have papillary and anaplastic thyroid carcinomas, respectively.
- One patient experienced subacute thyroiditis concurrently with anemia, hypoalbuminemia, and liver dysfunction, recovering fully without intervention.
Findings:
- Subacute thyroiditis can present atypically, particularly with nodular thyroid enlargement.
- Fine needle aspiration cytology may initially suggest subacute thyroiditis but can mask underlying thyroid malignancies.
- Thyroid malignancies can masquerade as subacute thyroiditis, highlighting diagnostic challenges.
Implications:
- Persistent or atypical presentations of suspected subacute thyroiditis, especially with nodularity, warrant comprehensive evaluation for thyroid cancer.
- This underscores the importance of vigilant diagnostic workups in endocrinology and oncology.
- Careful follow-up and repeat investigations are crucial for accurate diagnosis and timely management of thyroid disorders.
