Scanning electron microscopic and X ray microanalysis study of the mineral deposits in pseudoxanthoma elasticum.

1977

A skin biopsy of a 37 year old man with typical lesions of pseudoxanthoma clasticum (P.E.) associated with angioid streaks (Groenblad-Strandberg Syndrom) was examined with a scanning E. M. (SEM) and a SEM provided with a X ray micro-analyser. The SEM provided with X ray microanalyser enabled us to see the correspondence between the crystalline deposits and a calcium salt. The potassium, sodium and magnesium analysis of the specimen permits us to verify that the P.E. dermis is rich in K and poor in Mg.

Two-year-old girl with tuberous xanthomas.

2018

A 2-year-old girl was referred for evaluation because she had two nodular lesions located on both heels, and another elongated lesion in the intergluteal cleft. On physical examination, two yellow to orange well-defined nodules, suggestive of xanthomas, were bilaterally located on the Achilles tendon areas (figure 1A). Moreover, another yellowish, slightly raised lesion with band-like morphology was seen in the intergluteal cleft (figure 1B). There were no other anomalies on physical examination. Figure 1 (A) Tuberous xanthoma located on the left heel. (B) Planar xanthoma located in the intergluteal cleft. (C) Peripheral blood smear examination showing numerous red cells and two macrothromb…

No. of bitstreams: 0 Previous issue date: 2010-04-01 Verruciform xanthoma (VX) is a relatively rare benign lesion and oral predominantly, which occasionally affects skin and genital mucosa. It appears as a papule or single plaque showing a verrucous or papillomatous aspect, with variable color from reddish pink to gray. In majority of oral cases, it affects gingiva and alv…

Oral verruciform xanthoma : report of 13 new cases and review of the literature

2018

Background Oral verruciform xanthoma (OVX) is a rare lesion. The purpose of the present study is to describe the clinical features of 13 OVXs and review all cases reported in the English literature. Material and Methods Thirteen cases of OVX diagnosed during a 47-year period were retrospectively collected. The patients’ gender and age, as well as the main clinical features of the lesions were retrieved from the biopsy request forms. Pubmed®, Scopus® and Google ScholarTM electronic databases were searched with the key word “verruciform xanthoma”. Only cases of histologically confirmed OVX were included in the study. Results The 13 OVXs represented approximately 0.04% of 35,617 biopsies acces…

Autofluorescence Imaging of the Skin Is an Objective Non-Invasive Technique for Diagnosing Pseudoxanthoma Elasticum

2021

Pseudoxanthoma elasticum (PXE) is a rare multisystemic autosomal recessive connective tissue disease. In most cases, skin manifestations of PXE are the first to develop, followed later by severe ocular and cardiovascular complications. In our present study, in addition to dermoscopy, we introduced novel techniques, autofluorescence (AF) and diffuse reflectance (DR) imaging for the assessment of affected skin sites of five PXE patients. PXE-affected skin areas in most skin sites showed a previously observed pattern upon dermoscopic examination. With the novel imaging, PXE-affected skin lesions displayed high AF intensity. During our measurements, significantly higher mean, minimum and maximu…

Zur Frage humoraler Kollagen-Begleitkomponenten beim Pseudoxanthoma elasticum

1968

Bei einer 24jahrigen Kranken mit Pseudoxanthoma exsudativum werden bei eingehender, vor allem auch laboratoriumsmasiger Durchuntersuchung eine Herabsetzung der Hydroxyprolin-Ausscheidung und eine Vermehrung der Mucopolysaccharid-Ausscheidung im Urin festgestellt. Diese beiden Befunde entsprechen Ergebnissen, wie man sie nach vorangehenden eigenen Untersuchungen auch bei diffusen Bindegewebskrankheiten bzw. speziell bei progressiver Sklerodermie findet. Diese Resultate konnen somit als humoral fasbare Kollagen-Begleitkomponenten bei diesem Leiden gelten. Unter diesem Gesichtspunkt ware das Pseudoxanthoma elasticum mithin nicht nur eine systematisierte Elastose, sondern eher eine Kollagenoela…

Value of the Definition of Severe Familial Hypercholesterolemia for Stratification of Heterozygous Patients

2017

Familial hypercholesterolemia (FH) is characterized by high low-density lipoprotein (LDL) cholesterol with co-dominant transmission and high risk of cardiovascular disease (CVD), although with high variability among subjects. Currently, CVD stratification tools for heterozygous FH (HeFH) are not available. A definition of severe HeFH has been recently proposed by the International Atherosclerosis Society (IAS), but it has not been validated. Our study aims to see clinical characteristics and prevalence of CVD in subjects defined as severe HeFH by IAS criteria. Probable or definite HeFH introduced in the Dyslipidemia Registry of Spanish Arteriosclerosis Society were analyzed by the IAS crite…

Homozygous familial hypercholesterolemia with severe involvement of the aortic valve—A sibling‐controlled case study on the efficacy of lipoprotein a…

2020

Background Homozygous familial hypercholesterolemia (hoFH) can cause severe atherosclerotic cardiovascular disease (ASCVD) in early infancy. Diagnosis and initiation of effective lipid-lowering therapy (LLT) are recommended as early as possible to prevent ASCVD-related morbidity and mortality. Methods The clinical courses of a pair of siblings with an identical hoFH genotype, who exhibited major similarities of their clinical phenotype were analyzed in a case-control fashion including the family. Results The older sibling was diagnosed with hoFH at the age of 4. Untreated LDL-cholesterol (LDL-C) was 17 mmol/L (660 mg/dL). LLT including lipoprotein apheresis (LA) was initiated and has been s…
