Abstract
A 19-year-old male was found dead in his apartment. At autopsy he was morbidly obese (Body mass index; BMI - 40.5) with multiple areas of velvety pigmented thickening of the skin in folds around the neck, in the axillae, in the inframammary regions, over the anterior waistline and groin regions and over the dorsal aspects of the feet. These had the typical appearance of acanthosis nigricans. Internal examination revealed aspiration of gastric contents into the airways. Vitreous humour biochemistry showed markedly elevated levels of both glucose (62.9 mmol/L) and β-hydroxybutyrate (13.54 mmol/L). Death was, therefore, due to aspiration pneumonia complicating diabetic ketoacidosis on a background of morbid obesity. The initial indicator of underlying diabetes, in conjunction with obesity had been acanthosis nigricans.

Abstract
A physical examination represents a fundamental step in diagnosing diseases. Due to the role that hormones play in the regulation of numerous biological processes in various organs and systems, endocrine diseases cause a variety of clinical manifestations that can be easily identified with a careful physical examination and can guide the clinician to specific diagnoses. Furthermore, the presence of specific clinical signs in various endocrine-metabolic diseases can predict the risk of developing comorbidities and serious adverse events. In this article, we present some of the main clinical signs of endocrine-metabolic diseases and the risk of comorbidities, summarizing the pathogenetic mechanisms that lead to their formation. The aim is to highlight how the identification of these specific signs can reduce the number of dynamic tests and the costs necessary to reach the diagnosis and allow the early identification of any complications associated with these diseases, improving the clinical management of affected patients.

Severe Quantitative Scale of Acanthosis Nigricans in Neck is Associated with Abdominal Obesity, HOMA-IR, and Hyperlipidemia in Obese Children from Mexico City: A Cross-Sectional Study. Dermatol Res Pract 2022; 2022:2906189. [PMID: 35386232 PMCID: PMC8979734 DOI: 10.1155/2022/2906189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 02/07/2022] [Accepted: 03/12/2022] [Indexed: 11/17/2022] Open
Abstract
Background. Acanthosis nigricans (AN) is a clinical sign that commonly occurs in obesity; however, its specificity and sensitivity have been controversial. It is unknown if AN severity degree can be a useful marker for cardiometabolic disorders screening. We suggest that the stratified analysis of AN severity degree in neck by Burke’s scale could be a useful tool in the screening of cardiometabolic alterations in obese children. Objective. The aim of this study was the association of AN severity degree in neck by Burke’s scale with anthropometric, biochemical, and inflammatory parameters in obese school-age children from Mexico City. Methods. A cross-sectional study was conducted, including 95 obese school-age children stratified by AN severity degree in neck by Burke’s scale. Anthropometric and fasting biochemical measurements were determined. Variables were compared by x2 test for frequencies and one-way ANOVA with Bonferroni posttest for continuous variables. Linear regression analysis adjusted by gender, BMI, and age was performed to evaluate the association between AN severity degree and cardiometabolic alterations. Statistical significance was set at
. Results. As AN severity degree in neck by Burke’s scale increased, diastolic blood pressure (
) and triglycerides (
) significantly increased and adiponectin significantly decreased (
). Positive associations between grade 3 AN and waist circumference, HOMA-IR, triglycerides, total cholesterol, and LDL cholesterol were observed. Conclusion. Our findings could be used to identify an easier clinical tool to prevent obesity progression and its complications in pediatrics. There are no similar studies.

Abstract
BACKGROUND Early recognition of acanthosis nigricans is important because acanthosis nigricans can be a cutaneous manifestation of a variety of systemic disorders and, rarely, as a sign of internal malignancy. OBJECTIVE The purpose of this article is to familiarize pediatricians with the clinical manifestations, evaluation, diagnosis, and management of acanthosis nigricans. METHODS A search was conducted in November 2021in PubMed Clinical Queries using the key term "acanthosis nigricans". The search strategy included all clinical trials, observational studies, and reviews published within the past 10 years. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS Acanthosis nigricans is characterized by symmetric, hyperpigmented, and velvety plaques with ill-defined borders, typically involving intertriginous areas. Obesity is the most common cause of acanthosis nigricans which is increasingly observed in obese children and adolescents and can serve as a cutaneous marker of insulin resistance. Early recognition of acanthosis nigricans is important because acanthosis nigricans can also be a cutaneous manifestation of a variety of systemic disorders and, rarely, as a sign of internal malignancy. This may consist of weight reduction, discontinuation of causative drugs, treatment of underlying endocrinopathy, or treatment of an underlying malignancy. For patients with isolated acanthosis nigricans and for those whose underlying cause is not amenable to treatment, treatment of the lesion may be considered for cosmetic reasons. Topical retinoids, vitamin D analogs, chemical peels, and other keratolytics are often used for the treatment of localized lesions. Seldom, systemic therapy such as oral retinoids may be considered for extensive or generalized acanthosis nigricans and acanthosis nigricans unresponsive to topical therapy. Other uncommon treatment modalities include dermabrasion, laser therapy, and surgical removal. CONCLUSION Although acanthosis nigricans is treatable, a complete cure is difficult to achieve. The underlying cause should be treated, if possible, to resolve and prevent the recurrence of acanthosis nigricans. The diagnosis is mainly clinical, based on the characteristic appearance (symmetrically distributed, hyperpigmented, velvety, papillomatous, hyperkeratotic plaques with ill-defined borders) and the typical sites (intertriginous areas, flexural area, and skin folds) of the lesions. The diagnosis might be difficult for lesions that have atypical morphology or are in an unusual location. Clinicians should be familiar with the clinical signs, evaluation, diagnosis, and therapy of acanthosis nigricans because of the link between it and underlying diseases.

Abstract
This final article in the supplement aims to summarize a clinical approach for weight management geared toward primary care practitioners, offering practical advice about how to integrate weight management into day-to-day practice. To achieve long-term successful weight loss, a comprehensive multimodal approach is recommended, focusing on both lifestyle modification and appropriate use of therapy. Once-weekly subcutaneous semaglutide 2.4 mg is a novel treatment that can be used as an adjunct to lifestyle modification for the management of overweight and obesity. Key considerations are presented to support its optimal administration in conjunction with lifestyle modification, with a focus on assessing suitability and the importance of dose escalation and monitoring.

Abstract
AIM In the literature, there are no data examining the association with lichen planus with acanthosis nigricans and acrochordon, which are skin findings of metabolic syndrome (MS). MATERIALS A total of 108 lichen planus (LP) patients, age and sex-matched 109 controls, 217 patients in total were prospectively included in the study. RESULTS Metabolic Syndrome was found in 55 (50.9%) of 108 patients with lichen planus and 36.7% in the control group. The frequency of MS in the lichen planus group was found to be significantly higher than that in the control group (P = .03). The incidence of acanthosis nigricans (AN) was statistically higher in the LP group (P = .009). In addition, while 38 of 47 AN patients in the LP group had MS, 17 of 61 patients without AN had MS, and the presence of MS was found significantly higher in LP patients with AN (p˂0.001). The incidence of acrochordon was statistically higher in the LP group (P = .03). In addition, while 43 of 62 patients with acrochordon in the LP group had MS, 12 of 46 patients without acrochordon had MS, and the presence of MS was found significantly higher in patients with LP with acrochordon (P ˂ .001). CONCLUSION In our study, it was found that skin findings such as AN and acrochordon increased in patients with lichen planus. This increase was also observed in lichen planus patients with metabolic syndrome. Therefore, the association of acanthosis nigricans and acrochordon may be a predictive of metabolic syndrome in patients with lichen planus admitted to the dermatology outpatient clinic.

Acanthosis Nigricans in Children and Adolescents with Type 1 Diabetes or Obesity: The Potential Interplay Role between Insulin Resistance and Excess Weight. CHILDREN-BASEL 2021; 8:children8080710.

Abstract
Acanthosis nigricans (AN) is associated with obesity and type 2 diabetes, where insulin resistance (IR) is considered a predisposing factor. IR can also affect patients with type 1 diabetes (T1D). We evaluated the prevalence of AN in patients with T1D compared to subjects with obesity in order to define the interplay between IR and excess weight. We considered 138 pediatric patients who presented with T1D and 162 with obesity. As controls, 100 healthy normal-weight subjects were included. A physical examination with the detection of AN and biochemical assessments was performed. IR was calculated by using the homeostasis model assessment for IR in patients with obesity and the estimated glucose disposal rate in T1D. The AN prevalence was higher in T1D and obese subjects compared with controls in whom AN was not detected (p = 0.02 and p < 0.001, respectively). A greater number of AN cases were observed in subjects with obesity compared with T1D (p < 0.001). Patients with AN were older than subjects without AN (p = 0.005), and they had higher body mass index (BMI) values, waist circumference (WC), fasting triglycerides and blood pressure (all p < 0.001). Thirty-five patients with AN exhibited IR with an association between AN presence and IR in patients with obesity (p < 0.001). In T1D, there was an association between AN and being overweight/obese (p = 0.02), independently of IR. AN is a dermatological condition associated with obesity. In T1D, the presence of AN was significantly associated with overweight status or obesity but not IR. The presence of AN in the absence of IR supports the interplay role between impaired insulin signaling, IR and excess weight in the pathogenic mechanism.

Abstract
INTRODUCTION Waist circumference is a common anthropometric measure for predicting abdominal obesity and insulin resistance. We developed optimal waist circumference cut points for children aged 2 to 8 years in the US-Affiliated Pacific (USAP) region based on the relationship of waist circumference and acanthosis nigricans in this population. METHODS We conducted a cross-sectional analysis from the Children's Healthy Living Program's 2012-2013 data on 4,023 children. We used receiver-operating characteristic analysis to determine the sensitivity and specificity for acanthosis nigricans across waist circumference, by sex and age. We determined optimal waist circumference cutoff points corresponding to Youden index (J), (equal to [sensitivity + specificity] - 1), with acanthosis nigricans. We compared these cut points with the 90th percentile. RESULTS The 90th-percentile cut points for boys aged 2 to 5 years (58.15 cm) and 6 to 8 years (71.63 cm) were slightly higher than for girls in both age groups (aged 2-5 y, 57.97 cm; 6-8 y: 70.37 cm). The optimal cut points (corresponding to the highest sensitivity and specificity) were as follows: for boys aged 2 to 5 years, 90th percentile (58.25 cm; sensitivity, 48.0%; specificity, 91.5%); for boys aged 6 to 8 years, 78th percentile (63.59 cm; sensitivity, 86.8%; specificity, 82.8%); for girls aged 2 to 5 years, 62nd percentile (53.27 cm; sensitivity, 71.4%; specificity, 63.1%), and for girls aged 6 to 8 years, 80th percentile (63.63 cm; sensitivity, 55.4%; specificity, 82.9%). CONCLUSION Among USAP children, waist circumference was a reasonable predictor for acanthosis nigricans. Further analysis is warranted to examine causes of acanthosis nigricans at lower-than-expected waist circumference percentiles. The cut points can be used for early detection of metabolic risk.

Abstract
BACKGROUND Acanthosis nigricans (AN) is a cutaneous disorder characterized by symmetric velvety hyperpigmented plaques on intertriginous areas like axilla, neck, inframammary, and groin. AIMS To summarize the pathophysiology and classification of AN, provide an update of diagnostic testing strategies, and describe the current therapeutic options described so far in the literature for this disease. METHODS A comprehensive english language literature search across multiple databases (PubMed, EMBASE, MEDLINE, and Cochrane) for keywords (alone and in combination) was performed. MeSH as well as non-MeSH terms such as "acanthosis nigricans," "classification," "pathophysiology," "diagnosis," "treatment," "topical drugs," "systemic drugs," "chemical peeling," and "lasers" were taken into consideration. RESULTS The pathophysiology of AN revolves around a multifactorial stimulation of proliferation of epidermal keratinocytes and dermal fibroblasts. Various types of AN include benign, obesity-associated, syndromic, malignant, acral, unilateral, medication-induced, and mixed-type. Homeostasis model assessment-insulin resistance (HOMA-IR) is a good tool for assessment of insulin resistance. Management involves general measures (weight reduction and addressing the underlying cause, if any), topical drugs (retinoids, vitamin D analogs, and keratolytics), oral drugs (retinoids and insulin sensitizers), chemical peels (trichloroacetic acid), and lasers (Long pulsed alexandrite, fractional 1550-nm erbium fiber, and CO2 ). CONCLUSION Acanthosis nigricans is a treatable condition; however, complete cure and disappearance of lesions are difficult to achieve. Weight reduction is the most scientific and practical management strategy. Long-term studies and further research is warranted in the pathophysiology and treatment of this common condition.

Abstract
Metabolic syndrome (MeTS) is a well-known health-related problem with several end-organ damages and the resulted side effects such as rising in the blood glucose and lipid and blood pressure. Although MeTS might show several skin symptoms such as acanthosis nigricans, skin tags, acne, and androgenic alopecia, it could also be implicated in the pathophysiology of numerous dermatologic disorders. Furthermore, some dermatologic drugs might be implicated in the incidence or exacerbation of MeTS. Consequently, MeTS and skin problem could interfere closely with each other and each one could predispose the patient to the other one and vice versa. Remembering these close relationships help us to have better therapeutic choices regarding each inflammatory skin conditions. Moreover, some of the skin symptoms should be followed cautiously to define the underlying MeTS.

Abstract
INTRODUCTION Although type 2 diabetes mellitus (DM) is a global public health problem, the diabetes-associated dermatological (non-infectious) manifestations (DADM) remain poorly understood and under-diagnosed. We aimed to evaluate the prevalence of 7 known DADM in a primary care setting, and their association macro/microvascular complications. METHODS Cross-sectionnal study included patients consulting in general practice for DM-follow up, from November 2016 to January 2017. Patients aged <18 years old or consulting for other reason than DM follow up were excluded. Each patient were screened for diabetic dermopathy (DD), Huntley's papules (HP), necrobiosis lipoidica diabeticorum (NL), acanthosis nigricans (AN), cheiroarthropathy (CA, or stiff hand syndrom), scleredema adultorum of Buschke (SB) and bullosis diabeticorum (BD). RESULTS 213 diabetic patients were included over a period of 3 months. We found a prevalence of 17.8% (38 patients) for DD, 8.5% (18) for HP, 2.8% (6) for NL, 2.3% (5) for AN, 1.9% (4) for CA, 1.4% (3) for SB and 1.4% (3) for BD. DADM seems to be a risk factor for vascular complications (OR 1.97, p ≤ 0.001). Association with vascular involvement was stronger with DD and macroangiopathy (OR 1.86, p ≤ 0.001), and with NL and microangiopathy (OR 9.7, p ≤ 0.001). CONCLUSION In primary care, DM-associated dermatological manifestations present similar prevalence rates to a tertiary care setting, based on litterature. Complete dermatological examination of diabetic patients is essential and could lead to a better overall management of the pathology, as diabetic cutaneous manifestations appear as a sign of vascular involvement.

Abstract
Lipodystrophies are a heterogeneous group of physiological changes characterized by a selective loss of fatty tissue. Here, no fat cells are present, either through lack of differentiation, loss of function or premature apoptosis. As a consequence, lipids can only be stored ectopically in non-adipocytes with the major health consequences as fatty liver and insulin resistance. This is a crucial difference to being slim where the fat cells are present and store lipids if needed. A simple clinical classification of lipodystrophies is based on congenital vs. acquired and generalized vs. partial disturbance of fat distribution. Complications in patients with lipodystrophy depend on the clinical manifestations. For example, in diabetes mellitus microangiopathic complications such as nephropathy, retinopathy and neuropathy may develop. In addition, due to ectopic lipid accumulation in the liver, fatty liver hepatitis may also develop, possibly with cirrhosis. The consequences of extreme hypertriglyceridemia are typically acute pancreatitis or eruptive xanthomas. The combination of severe hyperglycemia with dyslipidemia and signs of insulin resistance can lead to premature atherosclerosis with its associated complications of coronary heart disease, peripheral vascular disease and cerebrovascular changes. Overall, lipodystrophy is rare with an estimated incidence for congenital (<1/1.000.000) and acquired (1-9/100.000) forms. Due to the rarity of the syndrome and the phenotypic range of metabolic complications, only studies with limited patient numbers can be considered. Experimental animal models are therefore useful to understand the molecular mechanisms in lipodystrophy and to identify possible therapeutic approaches.

Introduction of a novel quantitative scoring system for acanthosis nigricans and its validation in a pilot study. Dermatol Ther 2020; 33:e14450. [PMID: 33103332 DOI: 10.1111/dth.14450] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Revised: 10/01/2020] [Accepted: 10/23/2020] [Indexed: 12/30/2022]
Abstract
Inconsistent data exist regarding the diagnostic value of acanthosis nigricans (AN) or skin tags as clinical markers for obesity or diabetes. In an outpatient department-based prospective study, we designed a scoring for AN severity (SCANS) to evaluate AN and skin tags, their correlation with obesity or diabetes. Quantification of AN in six anatomic sites, in consideration of the affected skin surface areas, texture changes, number of skin tags, leads to a total severity score between 0 and 46. Among 336 adult patients (aged ≥18 years) with AN, a higher BMI was associated with AN (r = 0.299, P < .001), but not with diabetes (P = .43), as compared with 243 age- and sex-matched controls without AN. Among nondiabetics, AN scores were significantly correlated with waist circumference (r = 0.131, P = .024) and total cholesterol levels (r = 0.155, P = .04). Skin tags alone in the absence of AN were not associated with obesity (P = .333) or diabetes (P = .164). The total AN scores were positively correlated with the presence of skin tags (r = 0.132, P < .001), and the involvement of anterior neck (r = 0.668, P < .001) and axilla (r = 0.793, P < .001). Knuckles and groins were unaffected in our series. Our results indicate that combination of AN with skin tags can be used as clinical marker for obesity, but not for diabetes. Large-scale studies on patients of different ethnic background are required to further validate our proposed scoring.

Abstract
Background To date, very little information is available concerning the relationship between acanthosis nigricans (AN) and infection with human immunodeficiency virus type 1 (HIV-1). Case presentation Herein, we report the case of a middle-aged man admitted for fever and progressively worsening dyspnea in the context of an opportunistic pneumonia and firstly diagnosed with acquired immunodeficiency syndrome (AIDS). At the time of diagnosis, physical examination revealed the presence of a palpable, hyperpigmented skin lesion on the left areola with surface desquamation and velvety texture consistent with AN. Of note, the most common primary etiologies related to AN were excluded and the complete regression of the skin lesion was observed once antiretroviral therapy was started. Conclusion This is the second report of AN found in patients with AIDS and apparently responsive to prolonged antiretroviral treatment. Possible explanations of this association are still not completely understood, probably related to virus-induced changes in lipid metabolism. Our experience suggests that HIV testing should always be considered in the setting of apparently idiopathic AN.

Abstract
AIM The occurrence of acanthosis nigricans (AN) in childhood should not be underestimated since it acts as a cutaneous marker of underlying diseases, such as insulin resistance, endocrinopathy, syndromes and malignancy. The purpose of this review was to highlight the clinical significance of AN in childhood and draw attention to its possible role as early marker of alterations in glucose metabolism in obese children. METHODS The Cochrane Library and PubMed databases were searched for papers published in English up to April 2019. Observational studies, case reports and reviews from 1994 to 2019 were included. RESULTS Most of the cases of AN are associated with obesity. The prevalence of obesity is rising worldwide and is paralleled by global increases in the prevalence of metabolic syndrome in children. Insulin resistance and AN are closely associated. Evidence indicates that AN is a useful clinical marker for the identification of obese and overweight children and adolescents with insulin resistance who are susceptible to type 2 diabetes mellitus and metabolic syndrome. CONCLUSION In clinical practice, the recognition of AN is useful for an early identification of children and adolescents, prone to the insulin-resistant obese phenotype, who could benefit from early interventions.

Abstract
BACKGROUND Acanthosis nigricans (AN) is acquired hyperpigmentation of the intertriginous body regions. Histologically, AN is characterised by a thickened stratum corneum and a variable amount of acanthosis. Although benign and rarely symptomatic, AN may be a red flag for underlying pathologies. CASE PRESENTATION We analysed our patients with AN and could differentiate three different patterns, that are illustrated by one case report each. The is the benign AN associated with metabolic syndrome including obesity. The second type is the paraneoplastic AN malignancy which is associated with a wider range of malignancies. This type may occur before, after or with the clinical appearance of the malignancy. The third type is relapsing AN after complete remission. We present a patient who had a malignant AN and was treated successfully for his cancer. Years later, however, AN relapsed. In that case in association with the appearance of skin tags. Cancer restaging excluded a tumour relapse. His BMI was 31.2 kg/m2, and the diagnosis of benign AN was confirmed. CONCLUSIONS The diagnosis of AN remains incomplete without screening for metabolic syndrome and/ or cancer. The combination of AN and skin tags is more often associated with metabolic syndrome. AN may be considered as a red flag for malignancies and the metabolic syndrome.

Abstract
Metabolic syndrome, a commonly observed pathology and a global health issue, is closely related to the skin and thus dermatologists. The skin contributes to the development of metabolic syndrome and it is an end organ for it. Metabolic dysfunction is related to many skin disorders, some of which with high association and some of which with lower association. The diseases of highest association will be discussed in this article. These diseases are acne vulgaris, acanthosis nigricans, hidradenitis suppurativa, and psoriasis vulgaris.

Abstract
The increasing prevalence of Metabolic syndrome (MetS) is a worldwide health problem, and the association between MetS and skin diseases has recently attracted growing attention. In this review, we summarize the associations between MetS and skin diseases, such as psoriasis, acne vulgaris, hidradenitis suppurativa, androgenetic alopecia, acanthosis nigricans, and atopic dermatitis. To discuss the potential common mechanisms underlying MetS and skin diseases, we focus on insulin signaling and insulin resistance, as well as chronic inflammation including adipokines and proinflammatory cytokines related to molecular mechanisms. A better understanding of the relationship between MetS and skin diseases contributes to early diagnosis and prevention, as well as providing clues for developing novel therapeutic strategies.
