To determine the effectiveness of medical therapy in vulvar dystrophy,
a retrospective, single-institute clinicopathologic study of 285 cons
ecutive cases was carried out. Of the patients, 152 (53.3%) had squamo
us hyperplasia (SH), 72 (25.3%) had lichen sclerosus (LS), and 61 (21.
4%) had lichen sclerosus with areas of squamous hyperplasia (LS+SH). S
ymptomatic response was 84.8% at 3 months and 92.7% at 6 months in pat
ients with SH. These figures were 70.8% and 87.5% for patients with LS
and 68.8% and 80.3% for patients with SH+LS, respectively. Histopatho
logical response was 63.6% at 3 months and 74.8% at 6 months for patie
nts with SH. These figures were approximately 29% and 42% for LS, and
21% and 34% for patients with SH+LS, respectively. Corticosteroids for
squamous hyperplasia and testosterone for lichen sclerosus achieved a
high symptomatic response. However, histologic remission rates were p
oorer.
