A pregnancy complicated with fetal growth restriction in a patient with dystrophic epidermolysis bullosa

Dystrophic Epidermolysis Bullosa (DEB): How Can Pregnancy Alter the Course of This Rare Disease? An Updated Literature Review on Obstetrical Management with an Additional Italian Experience

Epidermolysis Bullosa (EB) is an extremely rare and disabling inherited genetic skin disease with a predisposition to develop bullous lesions on the skin and inner mucous membranes, occurring after mild friction or trauma, or even spontaneously. Within the spectrum of EB forms, dystrophic EB (DEB) represents the most intriguing and challenging in terms of clinical management, especially with regard to pregnancy, due to the highly disabling and life-threatening phenotype. Disappointingly, in the literature little focus has been directed towards pregnancy and childbirth in DEB patients, resulting in a lack of sound evidence and guidance for patients themselves and clinicians. The current study aims to contribute to the DEB literature with an updated summary of the existing evidence regarding the obstetrical and anesthesiological management of this rare disease. Furthermore, this literature review sought to answer the question of whether, and if so, in which way, the pregnancy condition may alter the course of the underlying dermatologic skin disease. Having all this information is indispensable when counseling a patient with DEB who desires a child or is expecting one. Finally, we reported own experience with a pregnant woman with a recessive DEB whom we recently managed, with a favorable outcome.

Squamous cell carcinoma in a pregnant woman with recessive dystrophic epidermolysis bullosa

We report the case of a pregnant woman with recessive dystrophic epidermolysis bullosa. During pregnancy, she presents with a large, rapidly growing, tumor on her right forearm, whose biopsy revealed an invasive squamous cell carcinoma. Amputation by the middle third of the forearm was performed at 21 weeks of pregnancy, without intra- or post-operative complications. The remainder of pregnancy was unremarkable and, at 36 weeks, she gave birth to a healthy baby. One month after delivery, a large lymph node conglomerate was detected in the right axilla, highly suggestive of metastatic disease and complete lymph node dissection was then performed. Despite the prompt institution of chemotherapy, the patient died a few months later due to metastatic disease.

Dystrophic epidermolysis bullosa in pregnancy: a case report of the autosomal dominant subtype and review of the literature

Epidermolysis bullosa (EB) is a group of inherited blistering skin diseases that vary widely in their pathogenesis and severity. There are three main categories of EB: simplex, junctional, and dystrophic. This classification is based on the level of tissue separation within the basement membrane zone and this is attributed to abnormalities of individual or several anchoring proteins that form the interlocking network spanning from the epidermis to the dermis underneath. Dystrophic EB results from mutations in COL7A1 gene coding for type VII collagen leading to blister formation within the dermis. Diagnosis ultimately depends on the patient's specific genetic mutation, but initial diagnosis can be made from careful examination and history taking. We present a pregnant patient known to have autosomal dominant dystrophic EB and discuss the obstetrical and neonatal outcome. The paper also reviews the current English literature on this rare skin disorder.
