RESULTS: Fourteen patients underwent bilat-eral total thyroidectomy (BTT), one patient re-quired BTT with central lymph node dissection, and one patient was subjected to BTT with func-tional lymph node dissection. On histopatholog-ical examination, left lobe EBF was diagnosed in four patients; left lobe EBF with bilateral pap-illary thyroid carcinoma (PTC) in two; left lobe EBF with left lobe PTC in one; left lobe EBF with left follicular adenoma in one; left lobe EBF with right lobe papillary thyroid microcarcinoma in one; bilateral EBF in one; right lobe EBF with ex-tramedullary hematopoiesis in one; right lobe EBF in three; right lobe EBF with right lobe med-ullary thyroid carcinoma in one, and right lobe EBF with bilateral lymphocytic thyroiditis in one. One of the five patients who underwent bone marrow biopsy was diagnosed with myelopro-liferative dysplasia, and another with polycythe-mia vera. Three patients were treated medically for anemia because no other pathological find-ings could be observed.CONCLUSIONS: There is a lack of literature data about the clinical significance of EBF in the thyroid gland in cases with no concomitant he-matological diseases. People who have been di-agnosed with EBF in the thyroid gland should be checked for hematological diseases.eninfo:eu-repo/semantics/closedAccessKey ThyroidMultinodular goiterEctopic bone formationOsseous metaplasiaReview Article273988998368083442-s2.0-85148678316Q2WOS:000951507500020N/A
