The Hailey-Hailey disease, or “familial chronic pemphigus”, is a rare autosomal dominant disease with incomplete penetrance, which manifests clinically with fragile vesicles/blisters and recurrent erosions in intertriginous regions and histologically with a suprabasal acantholysis. We describe the case of a 33 year old woman presenting a single submammary lesion since about 8 months; no family medical history was reported. The histological examination showed a “dilapidated brick wall” appearance, typical for pemphigus familiaris benignus chronicus and immunofluorescence was negative.
