Light micrograph section through the skin of a patient with epidermolysis bullosa (EB) showing cleavage of part of the epidermis. EB is a rare genetic disease of the connective tissues in the skin and mucosal membranes. In this condition, no collagen forms between the skin layers (the dermis and epidermis).
