Abstract
BACKGROUND

The incidence of Langerhans cell histiocytosis (LCH) is low, and involvement of the thyroid is even rarer, which results in high missed diagnosis or misdiagnosis rates.

CASE SUMMARY

We report a young woman with a thyroid nodule. Thyroid malignancy was suggested by fine needle aspiration, but she was eventually diagnosed with multisystem LCH, thus avoiding thyroidectomy.

CONCLUSION

The clinical manifestations of LCH involving the thyroid are atypical, and the diagnosis depends on pathology. Surgery is the main method for treating primary thyroid LCH, while chemotherapy is the main treatment method for multisystem LCH.

Keywords: Thyroid, Langerhans cell histiocytosis, Thyroidectomy, Treatment, Case report

Core Tip: The incidence of Langerhans cell histiocytosis (LCH) is low. We report a young woman with a thyroid nodule, and thyroid malignancy was considered by fine needle aspiration. But she was eventually diagnosed with multisystem LCH, avoiding thyroidectomy.
