Answer

Thyrotropin excess presents with secondary hyperthyroidism. Thyrotropinomas are very rare tumors. They present most frequently as macroadenomas. Whether thyrotropinomas are naturally aggressive or whether the aggressive and invasive behavior is the result of delayed diagnosis is unclear. Biologically inadequate thyrotropin presents with secondary hypothyroidism.
