Plasma cell granuloma of the thyroid
Journal of Clinical Pathology
|October 1, 1986
Summary
This study documents the first case of a plasma cell granuloma in the thyroid, an unusual reaction to a colloid nodule. The nodule contained plasma cells within fibroblastic stroma, with no signs of paraproteinaemia.
Area of Science:
- Endocrinology
- Pathology
Background:
- Thyroid nodules are common, but plasma cell granulomas are exceedingly rare.
Observation:
- A unique thyroid nodule presented with numerous polyclonal plasma cells within a cellular fibroblastic stroma.
- Residual thyroid tissue was observed centrally, suggesting a reactive process.
Findings:
- The observed exuberant granulation tissue was interpreted as an unusual reaction to a colloid nodule.
- No associated paraproteinaemia was detected, differentiating it from other plasma cell disorders.
Implications:
- This case expands the differential diagnosis for thyroid nodules.
- Highlights the importance of recognizing rare reactive processes in thyroid pathology.
