Pseudoxanthoma elasticum (PXE, OMIM # 264800) is an autosomal recessive, multisystemic disorder, associated with mutations of the ABCC6 gene. Ectopic mineralization is in the background of the clinical manifestations of the disease. Calcium-salt crystals are deposited primarily in the skin, in the Bruch membrane of the eyes, and in the vascular endothelium. Thus, in addition to the skin lesions, visual impairment and cardiovascular involvement also occur. Clinical symptoms show varying severity and display heterogeneous appearance. The identification of the phenotype and care of the patients require a multidisciplinary perspective based on the collaboration of a dermatologist, ophthalmologist, cardiologist, and clinical geneticist. The aim of our work is to describe the development of symptoms of the disease, in order to facilitate the diagnosis. In addition, we aim to draw attention to the importance of early diagnosis of pseudoxanthoma elasticum, and to present modern diagnostic methods. Considering the development of severe systemic complications, the early diagnosis with the collaboration between related specialists is crucial to provide optimal clinical care and management of the patients.

UI	MeSH Term	Description	Entries
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D010641	Phenotype	The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.	Phenotypes
D011561	Pseudoxanthoma Elasticum	An inherited disorder of connective tissue with extensive degeneration and calcification of ELASTIC TISSUE primarily in the skin, eye, and vasculature. At least two forms exist, autosomal recessive and autosomal dominant. This disorder is caused by mutations of one of the ATP-BINDING CASSETTE TRANSPORTERS. Patients are predisposed to MYOCARDIAL INFARCTION and GASTROINTESTINAL HEMORRHAGE.

D012867	Skin	The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D016570	Bruch Membrane	The inner layer of CHOROID, also called the lamina basalis choroideae, located adjacent to the RETINAL PIGMENT EPITHELIUM; (RPE) of the EYE. It is a membrane composed of the basement membranes of the choriocapillaris ENDOTHELIUM and that of the RPE. The membrane stops at the OPTIC NERVE, as does the RPE.
