Thyroiditis cause thrombocytosis?
by SierraGal, Jun 30, 2006 12:00AM
In Sept. 2005 had TSH 13.71, Free T4 7.3.was started on Levoxyl 50 mcg. Had some enlargement and nodules of the thyroid. Blood work also revealed elevation of platelets (568). Referred to hematalogist and had a bone marrow biopsy in Dec. 2005. The bone marrow biopsy was not conclusive for essential thrombocytosis. The thyroid nodules grew and had FNA May 2006
The biopsy showed lymphocytic thryoidits, no cancer. In May, TPO 1249,Antithyrogobulin Ab 291776. Pathologist suggested an open biopsy of the thyroid to rule out lymphoma. The platelets have gone up,this month 930,000. Hematologist to start me on Hydrea to lower the platelets once they reach a million.
Was referred to an ENT, head and neck surgeon for the open biopsy and he deferred it for a couple of months and said I should just have my thyoid out since it was larger than it was in May. Presently I am on Levoxyl 75 mcg. Since the thrombocytosis is idiopathic and my antithyroid levels are so high...could this be the cause of my thrombocytosis? I asked both the endocrinologist and the hematlogist this question last year and the answer was no. Now they are wondering????

The cause of essential thrombocytosis is unknown. Secondary thrombocytosis may develop as a result of, acute hemorrhage or infection , anemia, arthritis and other chronic inflammations, cancer, exercise, iron deficiency, medication (antithyroid), csteoporosis, removal of the spleen (splenectomy), polycythemia vera (a disorder affecting other red blood cells, as well as platelets), stress, or surgery.
Good Luck.
