In order to assess the prevalence of leiomyomata in patients diagnosed
with acromegaly, files of all women so diagnosed were obtained (n = 2
5). Eight of these patients had undergone hysterectomy. In eight of th
e remaining patients, assessment of the uterus was performed by gynaec
ological examination and transvaginal ultrasound. The prevalence of le
iomyomata was 81% (13/16) in patients who had undergone hysterectomy (
8/8) or who underwent gynaecological examination (5/8), In conclusion,
the very high prevalence of leiomyomata in patients diagnosed with ac
romegaly warrants the inclusion of growth hormone excess as a cause of
leiomyomata. Leiomyomata are a feature of the organomegalic syndrome
associated with acromegaly.
