Amyloid goiter in a child with familial Mediterranean fever.

A 7 year-old Turkish boy presented with a euthyroid goiter, which was noted during evaluation of familial Mediterranean fever. Amyloid deposits in the thyroid were found on fine-needle aspiration biopsy. Slight involution of the goiter within seven months may be attributed either to colchicine therapy or to treatment with levothyroxine and iodide.
