a representative sample of the French population (n = 533)
aged 65 years and over, reported that 37.5% of respondents
presented with dermatoporosis (12).
The prevalence of dermatoporosis is unclear. According to a
prospective study of 202 patients over 60 years of age, con-
ducted in the Geriatric Department of the University Hospital
of Toulouse (south-east France), 32% of hospitalized patients
had signs of dermatoporosis (11). A more recent study of Clinical manifestations of cutaneous fragility include atrophy,
mainly on sun-exposed areas (upper limbs, pre-tibial regions),
Bateman’s senile purpura, and spontaneous asymptomatic white
porcelain stellar pseudoscars. The lesions are more often located
around the cleavage/décolleté area and anterior aspect of the
legs in women, and forearms and forehead in men (Fig. 6) (10).
