Amyloid Goiter Secondary to Behcet's Disease: A Case Report and Literature Review.

Amyloid deposition in the thyroid gland is a common presentation, yet amyloid goiter remains relatively rare. Proper differentiation of this condition from other goiter types and malignancies is essential. Although amyloid extensively invades the thyroid gland, patients are usually euthyroid, and many different presentations may occur. We report a case of a 42-year-old male patient who was diagnosed with secondary amyloidosis due to Behcet's disease. He presented with clinical manifestations of hyperthyroidism and systemic amyloidosis complicated by chronic kidney disease, which is the first case of such an entity to be reported in Palestine.
