Abstract
H Syndrome is a rare genodermatosis. It may include facial involvement
such as : facial telangiectasia, both hypo- and hyperpigmented lesions,
hirsutism, swollen cheeks due to subcutaneous infiltration and
eczematous lesions. We describe a new facial phenotype with dermoscopic
and histological features in the spectrum of non-Langerhans cell
histiocytosis.
