J Cutan Pathol 2024; 51:348-352. [PMID: 38380692 DOI: 10.1111/cup.14603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 02/01/2024] [Accepted: 02/12/2024] [Indexed: 02/22/2024]
Abstract
Several cases of elastofibromatous lesion affecting the oral mucosa have been reported. Clinically, these lesions may appear as small exophytic lesions or less often as white lesions. Therefore, fibrous hyperplasia and leukoplakia are not uncommonly considered in clinical differential diagnosis. Microscopically, elastic and fibrous connective tissue deposition is seen. Rarely, elastofibromatous changes can be detected when assessing intraoral lesions, including cysts, salivary gland neoplasms, and epithelial dysplasia. Here we report two oral lesions showing elastofibromatous changes, expanding their clinicopathological spectrum. The first case was a 46-year-old man with a history of asymptomatic nodular lesion on the palate 1 year ago, diagnosed as giant cell fibroma with elastofibromatous changes. The second case was a 79-year-old woman who presented a pigmented and mildly symptomatic lesion on the mandibular alveolar mucosa several months ago, diagnosed as amalgam tattoo associated with elastofibromatous changes.

Abstract
Radiofrequency microneedling is a technique that allows energy to be delivered to specified target depths in the skin via needle electrodes and measures temperature and impedance within the tissue. This method of delivery and real-time feedback has increased safety and efficacy, providing clinically significant improvements in skin laxity, rhytids, and cellulite.

Abstract
Linear focal elastosis (LFE) is an uncommon, benign, acquired elastotic condition with uncertain pathogenesis. It is characterized clinically by asymptomatic, multiple, yellowish, elevated, irregularly indurated, striae-like lines or bands distributed horizontally across the lower and middle part of the posterior trunk. The histopathological hallmark of LFE is a focal increase of elastic fibres in the dermis. The differential diagnosis is varied, and striae distensae is the closest mimic of LFE. Response of LFE to treatment is often poor. The focus of this article is to provide insights into this condition for dermatologists.

Abstract
PURPOSE To review and summarize studies on the anatomy and involutional changes of the midface. METHODS A PubMed search was performed searching for studies on the anatomy and involutional changes concerning the midface. RESULTS The anatomy of the midface is complex. Studies of involutional change vary in scientific quality and have conflicting results. However, it appears that among the more common changes, there is a decrease in the maxillary and pyriform angle, with changes to the orbital floor position. Further, there appears to be an inferior migration of the fat compartments of the midface during aging, exacerbating the hollow of the palpebromalar groove and causing a deepening of the nasojugal groove. Changes to the volume of the buccal extension of the buccal fat pad exacerbate these changes and contribute to the gestalt changes associated with facial aging. Here, we review the major characteristics of soft tissue and bony changes on the midface, with special reference to their anatomic relationships. CONCLUSIONS The major findings characterizing midface aging are related largely to the soft tissue. However, more robust studies are required to quantify these changes and to appraise their impact on the overall manifestation of aging.

Abstract
Elastin is a crucial extracellular matrix protein that provides structural integrity to tissues. Crosslinked elastin and associated microfibrils, named elastic fiber, contribute to biomechanics by providing the elasticity required for proper function. During aging and disease, elastic fiber can be progressively degraded and since there is little elastin synthesis in adults, degraded elastic fiber is not regenerated. There is substantial evidence linking loss or damage of elastic fibers to the clinical manifestation and pathogenesis of a variety of diseases. Disruption of elastic fiber networks by hereditary mutations, aging, or pathogenic stimuli results in systemic ailments associated with the production of elastin degradation products, inflammatory responses, and abnormal physiology. Due to its longevity, unique mechanical properties, and widespread distribution in the body, elastic fiber plays a central role in homeostasis of various physiological systems. While pathogenesis related to elastic fiber degradation has been more thoroughly studied in elastic fiber rich tissues such as the vasculature and the lungs, even tissues containing relatively small quantities of elastic fibers such as the eyes or joints may be severely impacted by elastin degradation. Elastic fiber degradation is a common observation in certain hereditary, age, and specific risk factor exposure induced diseases representing a converging point of pathological clinical phenotypes which may also help explain the appearance of co-morbidities. In this review, we will first cover the role of elastic fiber degradation in the manifestation of hereditary diseases then individually explore the structural role and degradation effects of elastic fibers in various tissues and organ systems. Overall, stabilizing elastic fiber structures and repairing lost elastin may be effective strategies to reverse the effects of these diseases.

Abstract
ABSTRACT Elastic fibers are present as a thin line around the normal secretory coil of eccrine and apocrine glands, although they are virtually imperceptible with hematoxylin-eosin staining. Skin aging is a consequence of intrinsic and extrinsic factors, and glycation and ultraviolet irradiation are involved in this process favoring elastosis. We report an unusual and prominent perieccrine elastosis on the left temple in the vicinity of a basal cell carcinoma in a 78-year old man with type 2 diabetes, dyslipidemia, and hypertension. Very thick multilamellar and tortuous elastic fibers surrounded the eccrine coils. This increased amount of elastic fibers was confirmed by orcein staining as well as amyloid-P and lysozyme immunostaining. Perieccrine coil elastosis is a very unusual phenomenon that to the best of our knowledge has not been reported. Similar to dermal actinic elastosis, the presence of perieccrine coil elastosis in a skin cancer microenvironment might hypothetically promote tumor growth because of the release of elastin-derived peptides.

Post-Translational Modifications Evoked by Reactive Carbonyl Species in Ultraviolet-A-Exposed Skin: Implication in Fibroblast Senescence and Skin Photoaging. Antioxidants (Basel) 2022; 11:antiox11112281.

Abstract
Photoaging is an accelerated form of aging resulting from skin exposure to ultraviolet (UV) radiation. UV-A radiation deeply penetrates the dermis and triggers the generation of reactive oxygen species (ROS) which promotes damage to DNA, lipids and proteins. Lipid peroxidation results from the oxidative attack of polyunsaturated fatty acids which generate a huge amount of lipid peroxidation products, among them reactive carbonyl species (RCS) such as α, β-unsaturated hydroxyalkenals (e.g., 4-hydroxynonenal), acrolein or malondialdehyde. These highly reactive agents form adducts on free NH2 groups and thiol residues on amino acids in proteins and can also modify DNA and phospholipids. The accumulation of RCS-adducts leads to carbonyl stress characterized by progressive cellular and tissular dysfunction, inflammation and toxicity. RCS-adducts are formed in the dermis of skin exposed to UV-A radiation. Several RCS targets have been identified in the dermis, such as collagen and elastin in the extracellular matrix, whose modification could contribute to actinic elastosis lesions. RCS-adducts may play a role in fibroblast senescence via the modification of histones, and the sirtuin SIRT1, leading to an accumulation of acetylated proteins. The cytoskeleton protein vimentin is modified by RCS, which could impair fibroblast motility. A better identification of protein modification and carbonyl stress in the dermis may help to develop new treatment approaches for preventing photoaging.

Abstract
The purpose of this study is to investigate the exchange reaction taking place among the bovine serum albumin (BSA), 5,5'-dithiobis-(2-nitrobenzoic acid (ESSE), reduced glutathione, N-acetylcysteine, D-penicillamine (thiolates), and silver metal (AgI). For this purpose, stock solutions of BSA and Ellman's reagent were prepared by dissolving 264 mg of BSA in 5 ml of reaction buffer (0.1 M KH2PO4 at pH 7.8) and 23.8 mg of ESSE in 1.0 ml of reaction buffer which were mixed together. Mixture of BSA-AgI was prepared in a separate procedure by dissolving 0.17 mg of silver nitrate in 1 ml of reaction buffer and then dissolving BSA (200 mg) in the same solution of silver nitrate. Blocking of Cys-34 of BSA with AgI was confirmed by treating different dilutions of BSA-AgI (500 μM) solutions with the solutions of ESSE (85 μM) and ES- (85 μM) and recording the spectra (300-450) with a UV-visible spectrophotometer. The chromatographed AgI-modified BSA ((BSA-S)AgI)) samples (typically 500 μM) were subsequently mixed with thiolates (reduced glutathione, N-acetylcysteine, and D-penicillamine). AgI and modified BSA (typically 500 μM each) were treated with these low molecular weight thiolates and allowed to react overnight followed by chromatographic separation (Sephadex G25). The redox reactions of AgI-modified BSA with various low molecular weight thiols revealed a mechanically important phenomenon. In the case of reduced glutathione and N-acetylcysteine, we observed the rapid release of a commensurate amount of Ellman's anion, indicating that an exchange has taken place and low molecular weight thiols (RSH) substituted AgI species at the Cys-34 of BSA eventually forming disulfide (BSA-SSR) at Cys-34. It can be anticipated from the phase of study involving bovine serum albumin that low molecular weight thiolates (reduced glutathione and N-acetylcysteine) take off AgI which are attached to proteins elsewhere in the physiological system, making these toxic metals free for toxic action.

Abstract
Late-onset focal dermal elastosis is a rare cutaneous condition classified within the disorders of increased dermal elastic tissue. It is characterized clinically by multiple papules with predilection for the neck and other flexures, without systemic alterations, and histologically by focally increased elastic fibers in the reticular dermis. Several elastic tissue disorders share a similar clinical presentation in the skin. Distinction of late-onset focal dermal elastosis and other pseudoxanthoma elasticum mimickers from pseudoxanthoma elasticum is critical, as they are not associated to systemic lesions. We report here on a case of late-onset focal dermal elastosis and review the scientific literature on this unusual condition.

Abstract
ABSTRACT Papillary dermal elastolysis has been described in the setting of experimental combination nivolumab and cabiralizumab immunotherapy. We report a third patient with distinctive, generalized atrophic macules that developed after a morbilliform eruption during a clinical trial for treatment of metastatic pancreatic adenocarcinoma. Histopathological findings demonstrated diminished elastic fibers in the papillary dermis, associated with a histiocyte-rich infiltrate and increased dermal mucin, features that should clue the dermatopathologist to this condition.

Abstract
We describe the association of balanitis xerotica obliterans and differentiated penile intraepithelial neoplasia (PeIN) with dermal elastosis and "bramble-bush" elastic fibers in a diabetic patient with no history of penicillamine intake. An 84-year-old man presented with urethral obstruction syndrome that required postectomy, meatotomy, and foreskin excision. Histopathological examination revealed changes of lichen sclerosus and differentiated PeIN. Orcein staining showed striking dermal elastosis and transepidermal elimination of elastic fibers. At higher magnification, multiple serrations and buds arising from the borders of the elastic fibers were observed giving the so-called bramble-bush appearance. Balanitis xerotica obliterans is considered a premalignant disease, and 14% of patients have evidence of PeIN. The differentiated subtype can be difficult to diagnose because of the minimal basal cell atypia, so a striking dermal elastosis, which may even occur before the neoplasm becomes invasive, may facilitate its diagnosis. The term "acquired perforating dermatosis" seems appropriate to describe those cases of perforating elastosis that occurs in adults with systemic diseases. The bramble-bush appearance of elastic fibers is not specific for penicillamine-induced elastopathy, and it may occur in other diseases, such as diabetes mellitus. This peculiar morphology of elastic fibers may be related to the enzymatic imbalance between matrix metalloproteinases and lysyl oxidase, an enzyme required for the cross-linking of elastic fibers.

Abstract
Late-onset focal dermal elastosis is a clinical mimic of pseudoxanthoma elasticum that lacks associations with systemic disease. Although initial reports asserted that the disorder occurs only in the elderly, a growing body of case reports document cases in patients as young as 39 years. We present a case of a 59-year-old woman with this disorder. To reflect the broad age range of patients affected by this disorder, we propose the term "focal dermal elastosis."

Abstract
Elastic fibers are essential constituents of the extracellular matrix of higher vertebrates and endow several tissues and organs including lungs, skin and blood vessels with elasticity and resilience. During the human lifespan, elastic fibers are exposed to a variety of enzymatic, chemical and biophysical influences, and accumulate damage due to their low turnover. Aging of elastin and elastic fibers involves enzymatic degradation, oxidative damage, glycation, calcification, aspartic acid racemization, binding of lipids and lipid peroxidation products, carbamylation and mechanical fatigue. These processes can trigger an impairment or loss of elastic fiber function and are associated with severe pathologies. There are different inherited or acquired pathological conditions, which influence the structure and function of elastic fibers and microfibrils predominantly in the cardiorespiratory system and skin. Inherited elastic-fiber pathologies have a direct or indirect impact on elastic-fiber formation due to mutations in the fibrillin genes (fibrillinopathies), in the elastin gene (elastinopathies) or in genes encoding proteins that are associated with microfibrils or elastic fibers. Acquired elastic-fiber pathologies appear age-related or as a result of multiple factors impairing tissue homeostasis. This review gives an overview on the fate of elastic fibers over the human lifespan in health and disease.

OBJECTIVE The aim of this study was to investigate whether concomitant treatment of dutasteride and sildenafil could prevent structural changes in the penis of a BPH rodent model. METHODS Thirty-two adult male rats were divided into the following groups: Ctrl, untreated control rats; BPH, untreated spontaneously hypertensive rats (SHRs); BPH + D, SHRs treated with dutasteride; and BPH + DS, SHRs treated with dutasteride and sildenafil. All treatments were performed during 40 days, following which the penises were collected for histomorphometrical analysis. The results were compared via one-way ANOVA with Bonferroni's post-test, considering p values <.05 as significant. RESULTS The smooth muscle density decreased by 28.6% and 21.4% in BPH + D and BPH + DS, respectively, when compared to the BPH group. The sinusoid space density reduced by 32.2% in BPH, when compared to the Ctrl group; this density was also reduced by 22.6% in BPH + D, when compared to the BPH group. The density of the elastic fibers increased 51.6% and 65.6% in BPH + D and BPH + DS, when compared to the BPH group. CONCLUSION Treatment with dutasteride promoted morphological changes in the corpus cavernous of this BPH model. Concomitant treatment with sildenafil did not prevent the morphological changes caused by dutasteride; on the contrary, it also promoted a further increase in elastic fibers.

Abstract
Elastic fibers are essential assemblies of vertebrates and confer elasticity and resilience to various organs including blood vessels, lungs, skin, and ligaments. Mature fibers, which comprise a dense and insoluble elastin core and a microfibrillar mantle, are extremely resistant toward intrinsic and extrinsic influences and maintain elastic function over the human lifespan in healthy conditions. The oxidative deamination of peptidyl lysine to peptidyl allysine in elastin's precursor tropoelastin is a crucial posttranslational step in their formation. The modification is catalyzed by members of the family of lysyl oxidases and the starting point for subsequent manifold condensation reactions that eventually lead to the highly cross-linked elastomer. This review summarizes the current understanding of the formation of cross-links within and between the monomer molecules, the molecular sites, and cross-link types involved and the pathological consequences of abnormalities in the cross-linking process.

Abstract
INTRODUCTION Epidermoid cysts (ECs) are rare and occur in the head and neck regions with an incidence from 1.6 to 7% of all cysts. In the oral cavity, approximately 80 ECs have been reported, representing less than 0.01% of all cysts. CASE REPORT We report a case of a 26-year-old man who developed a large EC in the midline floor of the mouth causing nodular swelling in the submental region and speech and swallowing difficulties. The lesion was surgically excised by intraoral approach and microscopically revealed an EC associated with extensive elastofibromatous changes in the cystic capsule. CONCLUSION Oral EC with extensive elastofibromatous changes is a finding extremely rare. The meaning of this finding is unknown, but a traumatic origin or deposit disorder of elastic fibers is suggested. To the best of our knowledge, intraoral EC with elastofibromatous changes has not been reported to date.

Abstract
Along with collagen, elastic fibers are integral components of cutaneous connective tissue. A decrease in elastic fibers or loss thereof has been described in a number of clinically distinct skin diseases, both hereditary and acquired. In disorders associated with inflammation, elastophagocytosis is an important histological hallmark. Treatment is generally difficult.

Abstract
Pseudoxanthoma elasticum (PXE)-like papillary dermal elastolysis and focal dermal elastosis are acquired noninflammatory elastic tissue disorders. The skin lesions clinically resemble PXE without systemic involvement. We report the clinicopathological features of five cases and discuss the pathogenesis and differential diagnosis. Increased awareness of this newly described entity will broaden the differential diagnosis for dermatologists when encountering a similar case scenario.

Abstract
Collagenous and elastotic marginal plaques of the hand (CEMPH) is a rare, chronic keratoderma characterized by hyperkeratotic linear plaques located along the radial and ulnar aspects of the hands bilaterally. As an isolated finding, CEMPH occurs secondarily to chronic trauma and photodamage. Herein, CEMPH is described as a manifestation of alkaptonuria (AKU). In addition to keloidal collagen, ochronotic fibers and fragmented, thickened elastic fibers were observed. Additionally, mucin deposition-not previously described in this clinical context-was also identified. Given their overlapping clinicopathologic features, CEMPH due to AKU should be distinguished from the acquired variant as well as acrokeratoelastoidosis.

Abstract
The objective of this study was to construct a predictive model to identify aged care residents at risk of future skin tears. Extensive data about individual characteristics, skin characteristics, and skin properties were gathered from 173 participants at baseline and at 6 months. A predictive model, developed using multivariable logistic regression, identified five variables that significantly predicted the risk of skin tear at 6 months. These included: a history of skin tears in the previous 12 months (OR 3.82 [1.64-8.90], P = 0.002), purpura ≤20 mm in size (OR 3.64 [1.42-9.35], P = 0.007), a history of falls in the previous 3 months (OR 3.37 [1.54-7.41], P = 0.002), clinical manifestations of elastosis (OR 3.19 [1.38-7.38], P = 0.007), and male gender (OR 3.08 [1.22-7.77], P = 0.017). The predictive model yielded an area under the receiver operating characteristic curve of 0.854 with an 81.7% sensitivity and an 81.4% specificity. This predictive model could inform a simple but promising bedside tool for identifying older individuals at risk of skin tears.

Abstract
There exists a spectrum of solar elastotic variants based on the clinical and histopathologic findings. We present here a peculiar case of solar elastosis that is unusual in its anatomic location, relative lack of background actinic damage, and pattern of linearization. Its presentation suggests that other factors in addition to ultraviolet radiation may play a role in the pathogenesis of solar elastosis.

Abstract
Introduction: Pseudoporphyria is a rare photodermatosis with characteristics similar to
those of porphyria cutanea tarda, without, however, presenting abnormalities
in porphyrin metabolism. Its etiology is related to chronic kidney disease,
ultraviolet radiation and certain medications. The aim of the present study
is to describe a case of furosemide-related pseudoporphyria in a patient
with chronic kidney disease. Case description: A 76-year-old male patient with stage 4 chronic kidney disease and in
continuous use of furosemide presented ulcerated lesions with peripheral
erythema and central hematic crust in the legs. On a skin infection
suspicion, treatment with quinolone and neomycin sulfate was initiated,
without improvement. A biopsy of the lesion was performed, with
histopathological examination demonstrating findings compatible with
porphyria, although the patient did not present high porphyrin levels. The
diagnosis of furosemide-induced pseudoporphyria was then established, with
medication suspension, and there was a significant improvement of the
lesions. Discussion: There are few cases of pseudoporphyria described, but it is believed that
this condition is underdiagnosed, especially in patients with chronic kidney
disease. Both clinical and histopathological findings closely resemble
porphyria, differentiating it from normal levels of porphyrin in plasma,
urine, or feces. Conclusions: Although the lesions are mostly benign, they may increase the morbidity and
mortality of these patients, so a proper diagnosis and early treatment are
extremely important.

Abstract
A paradox is a seemingly absurd or impossible concept, proposition, or theory that is often difficult to understand or explain, sometimes apparently self-contradictory, and yet ultimately correct or true. How is it possible, for example, that oxygen "a toxic environmental poison" could be also indispensable for life (Beckman and Ames Physiol Rev 78(2):547-81, 1998; Stadtman and Berlett Chem Res Toxicol 10(5):485-94, 1997)?: the so-called Oxygen Paradox (Davies and Ursini 1995; Davies Biochem Soc Symp 61:1-31, 1995). How can French people apparently disregard the rule that high dietary intakes of cholesterol and saturated fats (e.g., cheese and paté) will result in an early death from cardiovascular diseases (Renaud and de Lorgeril Lancet 339(8808):1523-6, 1992; Catalgol et al. Front Pharmacol 3:141, 2012; Eisenberg et al. Nat Med 22(12):1428-1438, 2016)?: the so-called, French Paradox. Doubtless, the truth is not a duality and epistemological bias probably generates apparently self-contradictory conclusions. Perhaps nowhere in biology are there so many apparently contradictory views, and even experimental results, affecting human physiology and pathology as in the fields of free radicals and oxidative stress, antioxidants, foods and drinks, and dietary recommendations; this is particularly true when issues such as disease-susceptibility or avoidance, "healthspan," "lifespan," and ageing are involved. Consider, for example, the apparently paradoxical observation that treatment with low doses of a substance that is toxic at high concentrations may actually induce transient adaptations that protect against a subsequent exposure to the same (or similar) toxin. This particular paradox is now mechanistically explained as "Adaptive Homeostasis" (Davies Mol Asp Med 49:1-7, 2016; Pomatto et al. 2017a; Lomeli et al. Clin Sci (Lond) 131(21):2573-2599, 2017; Pomatto and Davies 2017); the non-damaging process by which an apparent toxicant can activate biological signal transduction pathways to increase expression of protective genes, by mechanisms that are completely different from those by which the same agent induces toxicity at high concentrations. In this review, we explore the influences and effects of paradoxes such as the Oxygen Paradox and the French Paradox on the etiology, progression, and outcomes of many of the major human age-related diseases, as well as the basic biological phenomenon of ageing itself.

Abstract
Photodynamic therapy (PDT) involves the use of photochemical reactions mediated through the interaction of photosensitizing agents, light, and oxygen for the treatment of malignant or benign diseases. Topical photosensitizers employed in dermatology are 5-aminolevulinic acid (5 ALA) and methyl aminolevulinate, classically used for the treatment of superficial non-melanoma skin cancer and their precursors. Recently the efficacy of PDT has been introduced in other benign diseases. Elastosis perforans serpiginosa (EPS) is a rare skin disorder characterized by transepidermal elimination of abnormal elastic fibers. Management of this condition is complicated, various methods have been used but with limited success. We report a case of EPS in a 30-yeard-old woman treated with 5 ALA-PDT. After 4 sessions the lesions have almost completely disappeared with no residual side effects. Therefore we present an effective and safe alternative for the treatment of EPS.

Abstract
Pseudoxanthoma elasticum (PXE) is a genetic metabolic disease with autosomal recessive inheritance caused by mutations in the ABCC6 gene. The lack of functional ABCC6 protein leads to ectopic mineralization that is most apparent in the elastic tissues of the skin, eyes and blood vessels. The clinical prevalence of PXE has been estimated at between 1 per 100,000 and 1 per 25,000, with slight female predominance. The first clinical sign of PXE is almost always small yellow papules on the nape and sides of the neck and in flexural areas. The papules coalesce, and the skin becomes loose and wrinkled. The mid-dermal elastic fibers are short, fragmented, clumped and calcified. Dystrophic calcification of Bruch's membrane, revealed by angioid streaks, may trigger choroidal neovascularization and, ultimately, loss of central vision and blindness in late-stage disease. Lesions in small and medium-sized artery walls may result in intermittent claudication and peripheral artery disease. Cardiac complications (myocardial infarction, angina pectoris) are thought to be relatively rare but merit thorough investigation. Ischemic strokes have been reported. PXE is a metabolic disease in which circulating levels of an anti-mineralization factor are low. There is good evidence to suggest that the factor is inorganic pyrophosphate (PPi), and that the circulating low levels of PPi and decreased PPi/Pi ratio result from the lack of ATP release by hepatocytes harboring the mutant ABCC6 protein. However, the substrate(s) bound, transported or modulated by the ABCC6 protein remain unknown. More than 300 sequence variants of the ABCC6 gene have been identified. There is no cure for PXE; the main symptomatic treatments are vascular endothelial growth factor inhibitor therapy (for ophthalmic manifestations), lifestyle, lipid-lowering and dietary measures (for reducing vascular risk factors), and vascular surgery (for severe cardiovascular manifestations). Future treatment options may include gene therapy/editing and pharmacologic chaperone therapy.

Abstract
Elastoma is a connective tissue nevus characterized by changes in elastic fibers.
It can be congenital or acquired, and is usually diagnosed before puberty.
Associated with osteopoikilosis, it is known as Buschke-Ollendorff syndrome.
Histopathology with specific staining for elastic fibers is critical for a
diagnostic conclusion. This report describes the case of a 7-year-old male
patient with lesions diagnosed as elastoma, with absence of bone changes in the
radiological imaging. This study aims to report the clinical presentation and
histological examination of such unusual disease.

Abstract
Papular elastorrhexis (PE) is an uncommon elastic tissue disorder clinically characterized by the onset of asymptomatic flesh-colored to whitish papules over the trunk and upper limbs in children. Its etiology remains unknown, although isolated familial cases have suggested that acquired and inherited forms of the disease may exist. We present the case of a 13-year-old boy with human immunodeficiency virus who presented with such lesions after immunological recovery from very low CD4+ counts after introducing highly active antiretroviral therapy. Because neutrophils and macrophages are implicated in elastin metabolism and degradation pathways, immune dysregulation might be another etiologic factor to be considered in this rare disease.

Abstract
A proper knowledge of noninvasive facial rejuvenation is integral to the practice of a cosmetic surgeon. Noninvasive facial rejuvenation can be divided into patient- versus physician-directed modalities. Patient-directed facial rejuvenation combines the use of facial products such as sunscreen, moisturizers, retinoids, α-hydroxy acids, and various antioxidants to both maintain youthful skin and rejuvenate damaged skin. Physicians may recommend and often prescribe certain products, but the patients are in control of this type of facial rejuvenation. On the other hand, physician-directed facial rejuvenation entails modalities that require direct physician involvement, such as neuromodulators, filler injections, laser resurfacing, microdermabrasion, and chemical peels. With the successful integration of each of these modalities, a complete facial regimen can be established and patient satisfaction can be maximized. This article is the first in a three-part series describing noninvasive facial rejuvenation. The authors focus on patient-directed facial rejuvenation. It is important, however, to emphasize that even in a patient-directed modality, a physician's involvement through education and guidance is integral to its success.

Abstract
This test-retest pilot study investigated the intra-rater reliability and reproducibility of non-invasive technologies to objectively quantify morphological (colour, thickness and elasticity) and physiological (transepidermal water loss (TEWL), hydration, sebum and pH) skin properties in an aged care population. Three consecutive measurements were taken from five anatomical skin sites, with the mean of each measurement calculated. The intra-class correlation coefficient (ICC) and the standard error of measurement (SEM) were used to examine the intra-rater reliability and reproducibility of measurements. Non-invasive technologies in this study showed almost perfect reliability for ultrasound measurements of the subepidermal low echogenicity band (SLEB) (ρ = 0·95-0·99) and skin thickness (ρ = 0·95-0·99) across all sites. The ICC was substantial to almost perfect for pH (ρ = 0·76-0·88) and viscoelasticity (ρ = 0·67-0·91) across all sites. Hydration (ρ = 0·53-0·85) and skin retraction (ρ = 0·57-0·99) measurements ranged from moderate to almost perfect across all sites. TEWL and elasticity were substantial to almost perfect across four sites. Casual sebum levels and most colour parameters showed poor ICC. The use of non-invasive technologies in this study provided an objective and reliable means for quantifying ageing skin and may offer future studies a valuable option for assessing skin tear risk.
