Abstract
Aplasia cutis congenita (ACC) is a congenital disorder that can be classified into nine types, with Type I ACC being the most common. Type V ACC associated with fetus papyraceus is a rare subtype of ACC. We report the case of a Type V ACC in a male newborn with extensive abdominal skin defects. The patient received conservative treatment using hydrogel foam and silicone foam dressings. Approximately five weeks later, the patient was discharged when more than 60% of the skin had completed epithelialization. After discharge from West China Second University Hospital, Chengdu , the patient continued to be followed up regularly at the Burns and Plastic Surgery Clinic at local hospital in Gansu. We followed up the child by telephone. After 4 months of follow-up, scar tissue formation was observed in the trunk area. The infant is 2 years and 5 months old now, physical examination did not reveal any organ problems.

Abstract
Aplasia cutis congenita (ACC) is a rare disease with an unclear pathogenic mechanism. ACC has been suggested to result from the disrupted development or degeneration of skin in the uterus. This study describes two cases that may have underlying pathogenic cause that have not been previously reported. Two neonates who were admitted to the neonatal intensive care unit due to "skin lesions on the limbs" without other deformities or complications were diagnosed with type VII ACC by dermatologist. The mothers showed positivity for hepatitis B virus (HBV) surface antigen and elevated level of HBV DNA copies, which may be related to ACC. But this association could be a coincidence. Both neonates were treated with antibacterial dressings and achieved satisfactory healing.

Epidermolysis Bullosa With Congenital Absence of Skin: Congenital Corneal Cloudiness and Esophagogastric Obstruction Including Extended Genotypic Spectrum of PLEC, LAMC2, ITGB4 and COL7A1. Front Genet 2022; 13:847150. [PMID: 35432467 PMCID: PMC9010945 DOI: 10.3389/fgene.2022.847150] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2022] [Accepted: 02/23/2022] [Indexed: 11/13/2022] Open
Abstract
Epidermolysis bullosa (EB) is a rare and genetically heterogeneous disorder characterized by skin fragility and blister formation occurring spontaneously or after minor trauma. EB is accompanied by congenital absence of skin (EB with CAS) in some patients. Pathogenic variants of COL7A1 are responsible for EB with CAS in the vast majority of cases. Type and subtype diagnosis of EB with CAS generally requires specific immunohistological examinations that are not widely available plus targeted gene analysis. The present study aimed to determine the clinical features of five patients affected by EB with CAS and to identify the underlying genetic defects using whole exome sequencing (WES) followed by focused analysis of the target genes. Four patients had generalized skin involvement and one had localized defects. Two patients exhibited extremely severe skin manifestations and congenital cloudy cornea along with pyloric atresia, and one had partial esophagogastric obstruction and anuria due to vesicoureteric obstruction. In the WES analysis, the average coverage of the target exons was 99.05% (726 of 733 exons), with a range of 96.4–100% for individual genes. We identified four novel and two known pathogenic/likely pathogenic variants of five distinct genes in the examined families: PLEC:c.2536G > T (p.Glu846Ter); LAMC2:c.3385C > T (p.Arg1129Ter); KRT5:c.429G > A (p.Glu477Lys); ITGB4:c.794dupC (p.Ala266SerfsTer5); COL7A1:c.5440C > T (p.Arg1814Cys); and COL7A1:c.6103delG. All alleles were inherited from the parents, except for the KRT5 variant as a de novo finding. The findings reveal extremely rare phenotypes found in EB with CAS, namely congenital cloudy cornea, esophagogastric obstruction, and anuria, and extend the genotypic spectrum of EB-related genes. The data confirm that WES provides very high coverage of coding exons/genes and support its use as a reasonable alternative method for diagnosis of EB. The present data from an underrepresented population in Southeast Asia could further broaden the knowledge and research on EB.

Abstract
Epidermolysis bullosa (EB) is a group of rare congenital genetic conditions that result in painful blistering of the skin and mucous membranes, which occur with minor trauma or friction. There are many types and subtypes of EB that need to be distinguished, as the management and prognosis of each can vary significantly. We aim to perform an up-to-date literature review on congenital EB for healthcare providers in pediatrics. We performed a review of existing literature in the English language on EB via PubMed Clinical Queries, using key words such as "epidermolysis bullosa", "congenital" and "children". We reviewed EB based on the following subheadings: epidemiology, diagnosis, therapy, prognosis, and clinical prediction guidelines. EB is due to mutation in a number of genes, some types are autosomal dominant while others are autosomal recessive. The underlying mechanism is a defect in attachment between or within the epidermis and dermis of the skin. There are four main types: epidermolysis bullosa simplex, dystrophic epidermolysis bullosa, junctional epidermolysis bullosa, and Kindler syndrome. The diagnosis is suspected based on symptoms and confirmed by skin biopsy and definitive genetic testing. The severity of EB can range from mild to fatal. Severe complications may arise in some EB types and subtypes within the eye, ear, nose, upper airway, gastrointestinal and genitourinary tracts. There is no cure for the condition to date. Optimal management must be multidisciplinary, and involves wound care, pain control, controlling infections, nutritional support, and prevention and treatment of complications. EB presents in different forms. Treatment is supportive. The prognosis of milder forms is good. Children severely affected with EB and their families live a misery life with impaired quality of life. Health care workers must be aware of the suffering in these families and proactively support them.

Abstract
BACKGROUND/OBJECTIVES Bart syndrome was initially described as association of congenital absence of skin (CAS), nail abnormalities, and epidermolysis bullosa (EB). Further reports of patients with CAS and EB have been made with wide clinical heterogeneity among them. Current guidelines recommend the elimination of eponyms and use of the descriptive term EB with CAS. METHODS We performed a PubMed and Medline database search of patients with Bart syndrome or EB with CAS. We included case reports or case series that contained clinical and demographic information. RESULTS After review, 55 articles were included, reporting 96 patients. CAS involved the lower extremities in all patients, with additional upper limb, trunk, or head involvement in 17%. In all patients, the time to healing ranged from 2 weeks to 6 months; most received only conservative treatment. The subtype and frequency of associated EB most frequently reported were recessive dystrophic EB (41.4%) and dominant dystrophic EB (22.8%). Extracutaneous features were present in 29 patients; with pyloric atresia and ear malformations being the most common. The prognosis varied based on the subtype of EB and the presence of additional comorbidities; 50% of the patients with junctional EB with pyloric atresia and CAS died during the first months of life, while mortality among those with recessive dystrophic EB was 6.8%. CONCLUSION Epidermolysis bullosa with CAS is a clinically heterogeneous disorder, most often associated with recessive dystrophic EB, but other EB subtypes may occur. Further investigations are necessary to better establish a pathological mechanism for CAS, and its association with EB.

Abstract
Congenital absence of skin (CAS) is a clinical sign associated with the main types of epidermolysis bullosa (EB). Very few studies have investigated the genetic background that may influence the occurrence of this condition. Our objective was to investigate genotype-phenotype correlations on EB with CAS through a literature revision on the pathogenic variants previously reported. A total of 171 cases (49 EB simplex, EBS; 23 junctional EB, JEB; and 99 dystrophic EB, DEB), associated with 132 pathogenic variants in eight genes, were included in the genotype-phenotype analysis. In EBS, CAS showed to be a recurrent clinical sign in EBS with pyloric atresia (PA) and EBS associated with kelch-like protein 24; CAS was also described in patients with keratins 5/14 alterations, particularly involving severe phenotypes. In JEB, this is a common clinical sign in JEB with PA associated with premature termination codon variants and/or amino acid substitutions located in the extracellular domain of integrin α6β4 genes. In DEB with CAS, missense variants occurring close to non-collagenous interruptions of the triple-helix domain of collagen VII appear to influence this condition. This study is the largest review of patients with EB and CAS and expands the spectrum of known variants on this phenomenon.
