Primary hypothyroidism is often accompanied with hyperprolactinemia and if the untreated disease persists longer hypophyseal adenoma consisting of thyreotropic cells might develop. On the other hand, although rarely, simultaneous occurrence of primary hypothyroidism and hypophyseal prolactin adenoma might be encountered. If substitutional therapy, after the establishment of euthyroid status, does not eliminate clinical signs of hyperprolactinemia and normalize prolactin levels, a decision can be made in favor of hyperprolactinemia within primary hypothyroidism. In that case possible tumor changes in the hypophysis will show regressive tendency towards final disappearance. However if clinical signs and hyperprolactinemia persist after the establishment of euthyroid status, especially if accompanied with compressive signs this should be regarded as a coincidence of primary hypothyroidism and hypophyseal prolactin tumor. We report two female patients with primary hypothyroidism and hypophyseal pseudomacroadenoma.
