Aw. Patrick et al., HYPERTHYROIDISM SECONDARY TO A PITUITARY-ADENOMA SECRETING TSH, FSH, ALPHA-SUBUNIT AND GH, Clinical endocrinology, 40(2), 1994, pp. 275-278
A 51-year-old man had been treated for hyperthyroidism with antithyroi
d drugs for 8 years. He was then found to have a large pituitary adeno
ma with biochemical evidence of overproduction of TSH, FSH and alpha-s
ubunit. Subsequent immunocytochemical and tissue culture studies confi
rmed secretion of these hormones. In addition, the tumour stained for
GH and was capable of GH production in vitro. This combination of horm
ones produced by a pituitary adenoma has not been previously reported.
