Overview

Practice Essentials

Epidermolysis bullosa (EB) is a group of inherited bullous disorders characterized by blister formation in response to mechanical trauma. Historically, epidermolysis bullosa subtypes have been classified according to skin morphology. [1, 2]

Discoveries of the molecular basis of epidermolysis bullosa have resulted in the development of diagnostic tools, including prenatal and preimplantation testing. Based on a better understanding of the basement membrane zone (BMZ) and the genes responsible for its components, newer treatments (eg, gene or protein therapy) may provide solutions to the skin fragility found in patients with epidermolysis bullosa.

Signs and symptoms

Important general points include age of onset; size, frequency, and location of blisters; possible inciting factors; prior diagnostic attempts; prior therapies; and extent of pain or pruritus.

Review of systems information that can be associated with different epidermolysis bullosa (EB) subtypes includes alteration of growth or development and evidence of mucosal involvement, including oral (which is demonstrated in the image below), nasopharyngeal, ocular, genitourinary, GI, or respiratory symptoms. A family history of blistering disease is an important finding to identify.

Perform a complete physical examination with an emphasis on inspection of all skin, as well as conjunctival, oral, and genital mucosae.
