Epidermolysis bullosa dystrophica, also known as Dystrophic EB (DEB) is a chronic skin condition caused when anchoring fibrils are abnormal, diminished, or absent. This causes a weak dermoepidermal junction, where the epidermis easily separates from the dermis causing much pain. This condition is caused by a … See more Anchoring fibrils (composed largely of type VII collagen) extend from the basal lamina of epithelial cells and attach to the lamina reticularis (also known as the reticular lamina) by wrapping around the reticular fiber ( See more • Epidermis (skin) • Dermis • Lamina propria • Connective tissue See more • "Skin Basement Membrane".
