An 81-Year-Old Woman with Recalcitrant Blisters
Epidermolysis bullosa acquisita (EBA) is a rare mucocutaneous blistering disorder with typical onset in adulthood. Diagnosis and management can be difficult owing to the variability in presentation and clinical manifestation. In this case, we explore a case of EBA as well as provide a general overview of the condition and its variants.Dermatopathology 2018;5:1-5
Abstract Epidermolysis Bullosa (EB) is a group of genetic conditions resulting in skin and mucosal membrane fragility. EB is characterised by chronic wounds and scarring, consequent functional limitations and high levels of pain. In its most severe forms, life expectancy is significantly foreshortened.

Plectin is a giant multifunctional cytolinker protein (500 kDa) expressed in several tissues with essential roles in striated and smooth muscles, epithelia and nerve. It is a component of hemidesmosomes, desmosomes and focal adhesion contacts where it interacts with actin and intermediate filaments. Pathogenic variants in the PLEC1 gene lead to a group of diseases including epidermolysis bullosa (simplex ogna with or without muscular dystrophy, myasthenic syndrome, or pyloric atresia) and isolated limb-girdle muscular dystrophy.
We report the morphological, ultrastructural and western blot analysis of 7 patients from six families carrying pathological variants in PLEC1: 3 with LGMD, 1 with LGMD+EB, 1 with EB+CMD and 2 with diffuse weakness. Skeletal muscle biopsies were performed in the seven patients; six adult patients (20 to 59 years of age; 3M/3F) and one female child (1 year old).
Abstract Recessive dystrophic epidermolysis bullosa (RDEB) is an inherited skin fragility disorder caused by loss-of-function mutations in COL7A1 encoding type VII collagen (C7), the major component of anchoring fibrils (AFs) that ensure dermal-epidermal adherence. From birth, RDEB patients endure lifelong skin and mucosal blistering with both local and systemic complications including aggressive metastatic squamous cell carcinomas (SCC).1 Currently, treatments are only symptomatic although clinical studies of novel therapeutics, including gene2 and cell3 therapies are emerging. One potential safety issue with suc...
Abeona Therapeutics announced that the FDA has placed a clinical hold on its planned Phase 3 clinical trial evaluating autologous cell therapy EB-101 in patients with recessive dystrophic epidermolysis bullosa.
Rhys has epidermolysis bullosa, a painful, life-limiting condition that has left him unable to walk.
Chronic pruritus causes major morbidity in epidermolysis bullosa (EB). The substance P-neurokinin 1 receptor (SP-NK1) pathway is a promising target for treating EB-related pruritus.
In conclusion, our results show that surgical correction followed by skin dressing changes is an effective approach to improving mitten-hand malformations in RDEB patients. PMID: 31502914 [PubMed - as supplied by publisher]
We report a case of a 39-year-old male with autosomal dominant dystrophic EB, presenting with bilateral leg swelling of one-week duration. There was no other significant past medical history. The physical examination was remarkable for scars and erosions over all body areas, with all extremities with blisters and ulcers covered, absent finger and toenails and bilateral lower extremity edema. Serum creatinine was 0.9 mg/dL, albumin 1.3 g/dL and urine protein excretion 3.7 g/24 h. Viral markers (hepatitis-B, C, and HIV), complement c3 and c4 levels and auto-immune antibody profile all remained neg...
Abstract Bullous diseases are uncommon in children; however, as they have the potential to affect quality of life, occasionally have long-term side effects in the setting of scarring processes, and carry a rare risk of underlying malignancy [e.g., with paraneoplastic pemphigus (PNP)], knowledge of their clinical presentation and treatment options is essential. Given the rarity of these conditions, our current state of knowledge is largely derived from case reports and case series, with a paucity of evidence-based recommendations. In this review, we discuss the clinical presentation of and treatment options for lin...
