Dermatology - Recessive dystrophic hereditary / epidermolysis bullosa
Hereditary epidermolysis bullosa refers to a range of uncommon genetic skin disorders. Disruption of the integrity of the outermost layer of the skin and/or the layer beneath it results in the development of blisters after an injury.
The classification is determined by the location where blisters form: epidermolytic or EB simplex (EBS), junctional EB (JEB), and dermolytic, or dystrophic, EB (DEB). Each contains multiple separate categories. Dystrophic Epidermolysis Bullosa (DEB) is a condition characterized by the formation of blisters underneath the basal lamina. The healing process in DEB results in scarring and the development of milia. These effects are caused by genetic alterations affecting the anchoring fibril type VII collagen.
The onset occurs throughout infancy or early childhood. The individual presents with enamel abnormalities accompanied by caries and parodontitis, as well as strictures and scarring in the oral mucous membrane and esophagus. Additionally, there are stenosis in the urethra and anus, along with ocular surface scarring. The person also has malnutrition, growth retardation, and anemia.
The most severe complication is the development of squamous cell cancer in cases with persistent recurring erosions.
Lesions that are dominant. The characteristic features of Cockayne-Touraine illness include blistering and abnormal growth of the skin on the extremities, as well as nail abnormalities. Additionally, the condition may cause the production of small cysts called milia and the development of scars, which can be either excessively thick or overgrown. Oral lesions are infrequent, and teeth typically appear normal. Recessive Dystrophic Epidermolysis Bullosa (RDEB) is characterized by the formation of blisters on the extremities, the presence of atrophic scars, and minimal or no involvement of the mucous membranes. The Hallopeau-Siemens variety of generalized, severe RDEB is highly disfiguring. At birth, there is widespread formation of blisters. Over time, these blisters continue to form and reoccur in the same areas, leading to significant scarring and the development of ulcers. Additionally, there is syndactyly, which is the fusion of fingers or toes, resulting in the loss of nails. In severe cases, the hands and feet may become deformed, resembling mittens, and there may be a limited range of motion due to flexion contractures.
Significant damage to the mucous membranes, abnormalities in tooth enamel, and tooth decay.
The diagnosis relies on the clinical presentation and medical history. The level of cleavage is determined by histopathology, and it is further characterized by electron microscopy and/or immunohistochemical mapping.
Management encompasses supportive skin care, supportive care for various organ systems, and systemic therapies for problems. Effective wound care, adequate dietary assistance, and rigorous infection prevention are of utmost importance. Patients with more serious conditions receive treatment comparable to that provided in a burn unit. After a gentle bathing and cleansing process, protecting emollients and nonadherent dressings are applied.
