Hereditary mucoepithelial dysplasia: unique histopathological findings in skin lesions.

Hereditary mucoepithelial dysplasia (HMD) is a rare, autosomal dominantly inherited, multisystem disease thought to be caused by abnormalities in desmosomes and gap junctions. HMD affects the skin, mucosae, hair, eyes and lungs. Nearly all patients clinically display the triad of non-scarring alopecia, well-demarcated mucosal erythema and erythematous intertriginous plaques.

Quality of life assessment and disease experience of patient members of a web-based hydroa vacciniforme support group.

Background/purpose: Hydroa vacciniforme (HV) is a rare photodermatosis that primarily affects children. It is characterized by photodistributed vesicles that heal with scarring. The purposes of this study are to perform the initial investigation into the effect of HV on quality of life (QoL) and gain insight into disease diagnosis and management.
