[Two cases of FSH secreting adenomas (author's transl)].
The authors report two cases of FSH secreting adenomas in men and attempt to draw out some features of these very uncommon pituitary tumors. Absence of gynecomastia is emphasized. Diagnosis proceeds from systematic radio-immunoassay of pituitary hormones. Evidence of FSH secretion results from paradoxical gonadotropin stimulation by TRH and secretory granules seen by electronic microscope. Immunofluorescence studies are still to perform. Dynamic testicular secretion and, in one case, histologic examination were performed.
