The Intersection of Dermatological Dilemmas and Endocrinological Complexities: Understanding Necrobiosis Lipoidica-A Comprehensive Review. Biomedicines 2024; 12:337. [PMID: 38397939 PMCID: PMC10887100 DOI: 10.3390/biomedicines12020337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Revised: 01/29/2024] [Accepted: 01/30/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Necrobiosis lipoidica (NL) is a rare granulomatous skin disorder with a predilection for females, often associated with diabetes mellitus (DM). This paper aims to comprehensively review the literature on NL, focusing on its association with DM, thyroid disorders, and the metabolic syndrome. METHODS A systematic search was conducted in English-language literature from inception to October 2023, utilizing PubMed. We identified 530 studies and selected 19 based on clinical significance, statistical support, and relevance to the paper's goals. RESULTS The coexistence of NL and DM is prevalent, with rates ranging from 11% to 65.71%. NL may precede DM diagnosis and a correlation between NL and increased daily insulin requirements has been observed in such patients. NL is suggested as a potential prognostic marker for DM complications; however, recent studies question this association, highlighting the need for further research. Studies in the context of NL and Thyroid Disease indicate a correlation, especially with autoimmune thyroiditis. Regarding NL and Metabolic Syndrome, the prevalence of metabolic syndrome among NL patients is notably higher than in the general population. Additionally, DM patients with ulcerated NL commonly exhibit hypertension or obesity, raising questions about the potential influence of hypertension and obesity on NL ulcerations. CONCLUSION Additional research is required to untangle the complex connections between NL and various comorbidities.

Abstract
ZusammenfassungDie Necrobiosis lipoidica (NL) ist eine seltene granulomatöse Erkrankung mit scharf begrenzten, teleangiektatischen, braun‐roten Plaques mit atroph‐gelblichen Zentren, die zu Ulzerationen neigen und hauptsächlich an den Schienbeinen auftreten. Bei Kindern ist NL sehr selten, jedoch sind die Therapieresistenz, das problematische kosmetische Erscheinungsbild, die schmerzhaften Ulzerationen und die mögliche Entwicklung von Plattenepithelkarzinomen besonders herausfordernd für diese Altersgruppe. Unsere Literaturrecherche inkludiert 29 Berichte über NL bei Patienten unter 18 Jahren, die seit 1990 auf PubMed, EMBASE und Medline publiziert wurden. Das mittlere Alter war 14,3 Jahre mit weiblicher Prädominanz von 2 : 1 und hoher Prävalenz von Diabetes mellitus (80%). Aus den Daten geht hervor, dass hochpotente topische Steroide bis zu zweimal täglich Behandlung erster Wahl sind. Therapierefraktäre Fälle können auf Tacrolimus umgestellt werden. Ulzerationen profitieren von phasenadaptierter Wundversorgung und antientzündlichen medizinischen Verbänden wie mit medizinischem Honig. Das Hinzufügen einer hyperbaren Sauerstoffbehandlung zur lokalen oder systemischen Therapie kann bei schwer behandelbaren ulzerierten Läsionen in Betracht gezogen werden. Therapieresistente Fälle können umgestellt werden auf topische Photochemotherapie oder systemische Behandlung mit TNF‐alpha‐Inhibitoren, systemischen Steroiden (bevorzugt bei Patienten ohne Diabetes), Pentoxifyllin oder Hydroxychloroquin. Necrobiosis lipoidica in der Kindheit ist mit über 40% fehlgeschlagenen Therapieversuchen schwer zu behandeln, weshalb weitere Forschung über Patientenregister empfohlen wird.

Abstract
Necrobiosis lipoidica (NL) is a rare chronic granulomatous disease that manifests as sharply demarcated, telangiectatic, brownish-red plaques with atrophic yellowish centers prone to ulceration and occurs predominantly on the shins. In children, NL is extremely rare, but resistance to therapy, troublesome cosmetic appearance, painful ulcerations, and possible development of squamous cell carcinoma in long-persisting lesions are challenges during treatment. Our review includes 29 reports of NL in patients aged <18 years published from 1990 on PubMed, EMBASE, and Medline. The mean age of patients was 14.3 years, with a female predominance of 2 : 1 and a high prevalence of diabetes mellitus (80%). Data showed that potent topical steroids up to twice daily is the first-line treatment. For refractory cases, therapy can be switched to tacrolimus. Ulcerations benefit from phase-adapted wound care and anti-inflammatory medical dressings such as medical honey. Adding hyperbaric oxygenation to local or systemic therapy in difficult-to-treat ulcerated lesions can be considered. Refractory cases may be switched to topical photochemotherapy or systemic treatment with TNF-α inhibitors, systemic steroids (preferably in non-diabetic patients), pentoxifylline, or hydroxychloroquine. Necrobiosis lipoidica in childhood is difficult to treat, with a treatment failure rate of 40%. Therefore, further research through patient registries is recommended.

Abstract
BACKGROUND Necrobiosis lipoidica (NL) is complicated by ulceration in up to 35% of cases. METHODS Retrospective study of patients with NL seen at our institution between January 1, 1992, and May 25, 2021, was conducted. Ulcerated NL (UNL, n = 83) and non-ulcerated NL (NUNL, n = 233) groups were compared. RESULTS Twenty-six percent (83/316) of patients with NL experienced ulceration. UNL was significantly more likely to be painful (52% vs. 36%, P = 0.01), was more likely to have a lesion-associated cutaneous malignancy (7% vs. 0%, P < 0.001), and had a larger median size (7 vs. 5 cm, P = 0.004) compared to NUNL. Vascular studies were performed on a subset of patients and revealed transcutaneous oxygen pressure (TcPO2) < 40 mm Hg in 53% and venous insufficiency in 62% with no significant differences between UNL and NUNL groups. In patients with unilateral ulceration, mean TcPO2 values (39.7 vs. 46.6 mm Hg), regional perfusion index <0.6 (29% vs. 14%), and TcPO2 < 40 mm Hg (43% vs. 14%) were worse in the ulcerated leg compared to the non-ulcerated leg, but these differences were not statistically significant. CONCLUSIONS UNL was more likely to be painful, develop lesion-associated malignancy, and be larger in size compared to NUNL. There were no statistically significant differences in venous insufficiency, arterial Doppler/ankle brachial index, or TcPO2 values between UNL and NUNL patients, however, a significant portion of the cohort demonstrated abnormal vascular studies, particularly on TcPO2 and venous insufficiency testing.

Abstract
Maturity-onset diabetes of the young (MODY) is a heterogeneous group of monogenic forms of diabetes mellitus with distinct clinical features. Clinical dermatological phenotypes in MODY patients are very rare in literature. This report describes a patient with HNF1A-MODY presenting with necrobiosis lipoidica (NL) and granuloma annulare (GA). A 39-year-old asymptomatic woman, with atypical diabetes diagnosed at age 17, has a confirmed HNF1A mutation on exon 2 (c.392G>A, p.R131Q), classified as Pathogenic by the ACMG guidelines. She has reasonable metabolic control using oral anti-diabetic medications and has no chronic diabetic complications. Clinical and histologic diagnoses of both NL and GA were made. We discuss these conditions and their association with MODY.

Abstract
We are currently in the midst of an international epidemic of diabetes mellitus (DM) and prediabetes. The prevalence of DM in the United States is estimated at 9.4% of the population across all ages, while an estimated 1 in 3 Americans (33.9%) has prediabetes. According to the WHO, about 60 million people suffer from diabetes in the European Region. Dermatologists may play an important role in tackling this epidemic via efforts to improve early detection of both diabetes and prediabetes. Dermatologists often treat patients with, or at risk of, diabetes. This includes patients who present with cutaneous manifestations such as acanthosis nigricans, as well as patient populations at increased risk, including those with psoriasis, hidradenitis suppurativa, and polycystic ovarian syndrome. Simple screening guidelines can be used to identify patients at risk, and screening can be performed via a single non-fasting blood test. The diagnosis of prediabetes is a key feature in diabetes prevention, as interventions in this group can markedly reduce progression towards diabetes. In addition to referral to a primary care physician, dermatologists may refer these patients directly to structured behavioral lifestyle intervention programs known as diabetes prevention programs. A significant portion of the population lacks routine care by a primary care physician, and current data indicates need for improvement in diabetes screening and prevention among patient groups such as those with psoriasis. These factors highlight the importance of the dermatologist's role in the detection and prevention of diabetes.

Abstract
Diabetes mellitus is a significant worldwide health concern and cutaneous manifestations are common. This review describes characteristic skin findings of diabetes, general skin findings related to diabetes, and findings related to diabetes treatment with a focus on clinical presentation, diagnosis, pathophysiology, epidemiology, and treatment. As the prevalence of diabetes continues to rise, cutaneous manifestations of diabetes mellitus likely will be encountered more frequently by physicians in all disciplines including dermatologists and primary care physicians. Accordingly, knowledge regarding the prevention, diagnosis, and management of cutaneous manifestations is an important aspect in the care of patients with diabetes.

Abstract
BACKGROUND Necrobiosis lipoidica (NL) is a rare granulomatous disorder of unknown aetiology. Randomized controlled studies are not available due to it being an orphan disease. OBJECTIVES We evaluated patients in 2 dermatological centres to cluster data about epidemiology, the therapeutic approaches for NL, and their efficacy. MATERIALS AND METHODS Comorbidity and the efficacy of the applied treatment was assessed for 98 patients. RESULTS We identified 54% of patients with concomitant diabetes and 19% with thyroidal disorders. Topical steroids (85.7%) were predominantly used followed by calcineurin inhibitors (31%) and phototherapy (41.8%). Systemically, fumaric acid esters were more frequently applied (26.8%) than steroids (24.4%) and dapsone (24.4%). Steroids, compression therapy, calcineurin inhibitors, phototherapy, fumaric acid esters, and dapsone showed remarkable efficacy. CONCLUSION Therapeutic options were chosen individually in accordance with the severity of NL and presence of ulceration. Topical calcineurin inhibitors, systemic application of fumaric acid esters, and dapsone represent effective alternatives to the use of steroids.

Abstract
Necrobiosis lipoidica is a rare chronic dermatitis found in diabetic patients. These skin lesions affect 0.3–1.2% of patients with diabetes mellitus. Our patient developed necrobiosis lipoidica on the trunk, an unusual location. Treatment of necrobiosis lipoidica is difficult, related to good glycemic control.
Introduction Necrobiosis lipoidica (NL) is a known chronic rare granulomatous dermatitis. NL typically occurs in the lower extremity, there have only been previously reported cases of NL on the face, scalp, forearms, and dorsum of the hands. However, truncal NL is not a typical location. Presentation of case A 67-year-old man known to have diabetes type 2, presented with a 3-year history of painful and itchy skin lesions on the right lateral chest wall. On clinical examination, he had a red discolored patch with superficial capillaries and yellow discoloration at the center. Based on the histological examination, necrobiosis lipoidica was confirmed. Initial treatment with clobetasol propionate, tacrolimus, and topical corticosteroid cream was unsuccessful, and further NL lesions developed on the lower limb. Discussion NL rash is characterized by its location in the lower limbs and rarely involves fingers, hands, scalp, or face. It is noteworthy that the patient presented with NL skin lesions bon the trunk, which is outside the usual presentation. The prevalence of NL ranges from 0.3% to 1.2% among patients with diabetes mellitus. The treatment of NL is usually difficult. Initial management includes smoking cessation and proper diabetes control. In addition, intralesional and topical corticosteroids might be effective. In this case report, there was no improvement in NL despite the use of topical corticosteroids. Conclusion Immediate diagnosis and treatment of NL may prevent disease progression; therefore, the diagnosis of NL should be considered, even in an unusual location.

Abstract
Importance Necrobiosis lipoidica (NL) is a rare granulomatous condition. Current knowledge of its key features is based on a limited number of studies and case reports, leading to wide variability in the characterization of its defining features, with limited comparison of patients with or without diabetes. Objective To evaluate the epidemiologic characteristics, clinical features, and disease associations of NL in patients with or without type 1 or 2 diabetes. Design, Setting, and Participants This multicenter retrospective review included 236 patients aged 15 to 84 years who were evaluated and received a diagnosis of NL at the University of Pennsylvania Health System between January 1, 2008, and July 15, 2018; University of Iowa Hospitals and Clinics between January 1, 2000, and June 15, 2018; and Brigham and Women's Hospital and Massachusetts General Hospital between January 1, 2000, and February 15, 2018. Main Outcomes and Measures Patient demographics, clinical features, medical comorbidities, and biopsy status. Results Of the 236 patients with NL, 200 were women and 36 were men, and 182 were white, with a median age at presentation of 50.0 years (interquartile range, 33.0-59.0 years). The diagnosis was biopsy proven in 156 patients (66.1%). Of the 230 patients with location specified, 225 (97.8%) had NL on the lower legs. A total of 138 patients with NL (58.5%; 95% CI, 52.7%-65.3%) had diabetes. The median hemoglobin A1c for patients with diabetes was 8.00% (interquartile range, 6.68%-9.50%) (to convert hemoglobin A1c to proportion of total hemoglobin, multiply by 0.01). Patients with diabetes were significantly younger than patients without diabetes (median age, 45.0 vs 52.0 years; P = .005), and slightly less likely to be female (112 of 138 [81.2%] vs 87 of 96 [90.6%]; P = .046), but lesion characteristics were otherwise comparable. Other notable comorbidities included obesity in 95 of 184 patients (51.6%; 95% CI, 44.4%-58.9%), hypertension in 104 of 230 patients (45.2%), dyslipidemia in 98 of 225 patients (43.6%), and thyroid disease in 56 of 229 patients (24.5%). Conclusions and Relevance This study of NL supports its associations with diabetes as well as obesity, hypertension, dyslipidemia, and thyroid disease. Younger age and female sex were observed more frequently in patients with diabetes. Otherwise, NL lesions in patients with or without diabetes shared many clinical features, suggesting that risk factors outside of elevated blood glucose may play an important role in the disease. Future studies should evaluate these associations with the goal of further elucidating NL's underlying pathophysiologic characteristics.

Abstract
Necrobiosis lipoidica (NL) is a rare chronic granulomatous inflammatory skin disease characterized by brownish-red papules and yellowish plaques with atrophic centers, which usually affect the legs, bilaterally. The average age of onset is 30-40 years, and there are very few reported cases of necrobiosis lipoidica in children. A nondiabetic girl aged 14 years presented to our clinic with a history of an asymptomatic, 7 × 5-cm single red plaque over her back in the interscapular area, which had started 5 years ago. Her laboratory tests were normal. A histopathologic evaluation confirmed the diagnosis of NL, and local treatment with clobetasol propionate twice daily was administrated. The patient will be followed up to monitor plasma glucose levels and evaluation of the lesion. Herein, we report a pediatric patient without diabetes mellitus who had NL in an atypical location and review the literature in view of the clinical features, complications, and treatment regimens for NL in children.

Abstract
Cutaneous granulomatosis is a heterogeneous group of diseases, characterized by a skin inflammatory reaction triggered by a wide variety of stimuli, including infections, foreign bodies, malignancy, metabolites, and chemicals. From a pathogenic point of view, they are divided into non-infectious and infectious granulomas. Pathophysiological mechanisms are still poorly understood. Non-infectious granulomatous skin diseases include granuloma annulare, necrobiosis lipoidica, rheumatic nodules, foreign body granulomas, cutaneous sarcoidosis, and interstitial granulomatous dermatitis. Necrobiosis lipoidica is more frequent in diabetic patients. Infectious granulomas of the skin are caused by mycobacteria, in particular Mycobacterium tuberculosis or atypical mycobacteria; parasites, such as Leishmania; or fungi. Pathogenic mechanisms of M. tuberculosis-related granuloma are discussed. From a clinical point of view, it is useful to divide cutaneous granulomatosis into localized and more disseminated forms, although this distinction can be sometimes artificial. Three types of localized granulomatous lesions can be distinguished: palisaded granulomas (granuloma annulare, necrobiosis lipoidica, and rheumatoid nodules), foreign body granulomas, and infectious granulomas, which are generally associated with localized infections. Disseminated cutaneous granulomas can be divided into infectious, in particular tuberculosis, and non-infectious forms, among which sarcoidosis and interstitial granulomatous dermatitis. From a histological point of view, the common denominator is the presence of a granulomatous inflammatory infiltrate in the dermis and/or hypodermis; this infiltrate is mainly composed of macrophages grouped into nodules having a nodular, palisaded or interstitial architecture. Finally, we propose which diagnostic procedure should be performed when facing a patient with a suspected cutaneous granulomatosis.

Abstract
Metabolic diseases are commonly encountered in the Western world. Cutaneous manifestations are common in metabolic disorders, such as diabetes mellitus (DM) and the metabolic syndrome (MetS), and metabolic diseases may manifest with specific skin findings. MetS and DM share a common mechanism in their etiopathogenesis. As a result, the skin findings associated with these two diseases partially overlap. Several skin findings in DM and MetS may be the first clinical features of the disease, and early diagnosis facilitates treatment, thereby helping in preventing long-term complications. In this review, MetS and skin manifestations associated with DM are discussed.

Abstract
A granuloma is a form of inflammation, which predominantly consists of macrophages. It typically develops when the immune system attempts to enclose substances that are usually insoluble and cannot be eliminated to prevent the spread of these substances to the other body compartments. According to the source of the substances, granulomatous diseases can be divided into two groups: infectious and non-infectious. The mechanisms of infectious granuloma formation have been widely investigated because of its easy reproducibility in experimental models, both in vivo and in vitro. On the contrary, mechanisms of non-infectious granuloma formation have not been well investigated because of the difficulty to reproduce this formation in experimental models. In this article, we review our recent understanding of the histogenesis and pathogenesis of granuloma formation, confirmed from studies of infectious granulomas, and we present potential hypotheses of the histogenesis and pathogenesis of non-infectious granulomas based on clinical investigations.

BACKGROUND Necrobiosis lipoidica (NL) is a rare granulomatous inflammatory skin disease of unknown pathophysiology. Its potential association with diabetes mellitus is well known. Other relevant cofactors and comorbidities are subject to controversial debate. PATIENTS AND METHODS DRG (diagnosis-related groups) data of all inpatients with a coded primary or secondary diagnosis of NL treated at German hospitals in 2012 were evaluated. RESULTS Data of 262 inpatient cases with the primary or secondary diagnosis of NL were analyzed. Women (63.4%; n = 166) were nearly twice as frequently affected as men (36.2%; n = 96). Most NL patients (14.8%) were in the age group between 50 and 55 years. Among comorbidities included in the metabolic syndrome complex, diabetes mellitus was the most common (34.4%; IDDM 20.6%, NIDDM 13.8%), while essential hypertension was observed in 9.2%, obesity in 4.6%, chronic heart failure in 4.1%, and dyslipidemias in 2.3% of cases. Leg ulcers were diagnosed in 7.3% of individuals; other venous disorders, in 5.7%. CONCLUSIONS Our data analysis describes one of the largest compilations of patient cases with the diagnosis of NL worldwide. Besides the well-known association with diabetes mellitus, there are numerous other potentially relevant cofactors and comorbidities that should be considered in the diagnosis and management of NL patients.

Abstract
Necrobiosis lipoidica is a granulomatous condition presenting as indolent atrophic plaques, often on the lower extremities. There is a multitude of case reports suggesting possible associations and documenting different therapeutic alternatives with varied success. Important complications include ulceration and the development of squamous cell carcinoma. The disease course is often indolent and recurrent despite treatment. This article reviews the etiopathogenesis, clinical presentations, and evidence for treatment alternatives of this condition.

Abstract
Granulomatous disorders affecting the skin belong to a heterogeneous group of diseases. With the exception of granulomas induced by infectious agents or foreign bodies, the etiopathogenesis of granulomatous disorders is still poorly understood. The knowledge of histopathologic changes is of great importance for understanding clinical presentation and disease course.

Abstract
Granulomatous disorders of the skin are diverse and include infectious and non-infectious conditions. They are a source of confusion to many dermatologists and pathologists, including even the most experienced dermatopathologists. Correlation with clinical picture, serology, microbiology and careful morphological examination is essential for accurate diagnosis. Most cases require ancillary histopathological studies to reach a final diagnosis. This review discusses important non-infectious granulomatous conditions of the skin and presents a practical approach when confronted with such entities.

Abstract
INTRODUCTION AND OBJECTIVES Necrobiosis lipoidica (NL) is a chronic idiopathic granulomatous disease considered to occur in association with diabetes mellitus. Data on the frequency of this association, however, are inconsistent. Our aim was to retrospectively analyze the clinical characteristics of patients diagnosed with NL at our hospital and to investigate the association with diabetes mellitus and other diseases. MATERIAL AND METHODS We performed a chart review of all patients with a clinical and histologic diagnosis of NL treated and followed in the dermatology department of Hospital de Bellvitge in Barcelona, Spain between 1987 and 2013. RESULTS Thirty-five patients (6 men and 29 women with a mean age of 47.20 years) were diagnosed with NL in the study period. At the time of diagnosis, 31 patients had pretibial lesions. Thirteen patients (37%) had a single lesion at diagnosis, and the mean number of lesions was 3.37. Twenty-three patients (65.71%) had diabetes mellitus (type 1 in 10 cases and type 2 in 13). In 20 patients, onset of diabetes preceded that of NL by a mean of 135.70 months. The 2 conditions were diagnosed simultaneously in 3 patients. None of the 35 patients developed diabetes mellitus during follow-up. Six patients had hypothyroidism, and 4 of these also had type 1 diabetes. CONCLUSIONS NL is frequently associated with type 1 and 2 diabetes. Although diabetes tends to develop before NL, it can occur simultaneously.

Abstract
Obesity and diabetes are chronic diseases that affect people all over the world, and their incidence is increasing in both children and adults. Clinically, they affect a number of organs, including the skin. The cutaneous manifestations caused or aggravated by obesity and diabetes are varied and usually bear some relation to the time that has elapsed since the onset of the disease. They include soft fibromas, acanthosis nigricans, striae, xerosis, keratosis pilaris, plantar hyperkeratosis, fungal and bacterial skin infections, granuloma annulare, necrobiosis lipoidica, psoriasis, and atopic dermatitis. In this review article we present the skin changes found in children with diabetes mellitus and obesity and related syndromes and highlight the importance of the skin as a tool for establishing clinical suspicion and early diagnosis of systemic disease.

Abstract
Context: Necrobiosis lipoidica (NL) is a chronic granulomatous dermatitis that is commonly associated with diabetes mellitus. Most of the current knowledge about this entity is from western literature. Aims: This study evaluates the clinicohistological features of NL in an Indian scenario. Materials and Methods: We retrospectively reviewed clinical features, associated comorbidities, and biopsies of all patients with NL over a period of one year. Results: Five cases of NL were seen during the duration of the study. The preliminary clinical diagnosis ranged from sarcoidosis to tinea incognito. The commonest clinical presentation in the Indian scenario was of asymptomatic erythematous to skin-colored plaques and nodules on the shins with or without central atrophy. The most common site of involvement was the shin (3 of 5 patients). NL was associated with Diabetes mellitus in only two cases, both of whom were male patients. On histology, various patterns of inflammation were seen including the palisading, interstitial, and mixed granulomatous infiltrates. One patient had sarcoidal granulomas in association with an interstitial pattern. Features seen consistently in all cases include perivascular lymphoplasmacytic infiltrates, interstitial lymphocytic infiltrates, and fibroplasia. Interstitial mucin deposition was not observed in any of the biopsies. Conclusion: The diagnosis of NL was missed in most cases due to the rarity of the disease, absence of concomitant diabetes, and atypical presentations. Histology was a useful tool in clinching the diagnosis.

Abstract
Diabetes mellitus affects every organ of the body including the skin. Certain skin manifestations of diabetes are considered cutaneous markers of the disease, whereas others are nonspecific conditions that occur more frequently among individuals with diabetes compared with the general population. Diabetic patients have an increased susceptibility to some bacterial and fungal skin infections, which account, in part, for poor healing. Skin complications of diabetes provide clues to current and past metabolic status. Recognition of cutaneous markers may slow disease progression and ultimately improve the overall prognosis by enabling earlier diagnosis and treatment.

Abstract
Necrobiosis lipoidica is a rare granulomatous disorder of the skin. In up to 30% of the affected patients it can lead to ulcerations, which can impair the quality of life and are also very difficult to treat. Its pathogenesis is not fully understood. Only few studies focussing on necrobiosis lipoidica can be found, but none of them focus on ulcerated necrobiosis lipoidica. Therefore, we collected demographic data and comorbidities and assessed treatment options for patients with ulcerated necrobiosis lipoidica. Data of patients who were treated in the wound care centre of the University Hospital of Essen for ulcerated necrobiosis lipoidica over the past 10 years were retrospectively analysed. Hence, data of altogether ten patients (nine women and one man) with ulcerated necrobiosis lipoidica were collected. Of these, 70% of the patients had diabetes mellitus of which 30% had type I diabetes and 40% had type II diabetes; 60% of the patients suffered from arterial hypertension, obesity and hypercholesterolaemia; 40% of the patients suffered from psychiatric disorders such as depression and borderline disorder. Our clinical data demonstrate an association of ulcerated necrobiosis lipoidica and aspects of metabolic syndrome. This leads to a conclusion that ulcerating necrobiosis lipoidica can be seen as part of a generalised inflammatory reaction similar to the inflammatory reaction already known in the pathophysiology of rheumatoid diseases or psoriasis. In patients with clinical atypical painful ulcerations, necrobiosis lipoidica should be considered as a possible differential diagnosis. Therapists should be aware of associated aspects in patients with ulcerated necrobiosis lipoidica who besides diabetes often suffer from other aspects of a metabolic syndrome with increased cardiovascular risk factors. Therefore, these related comorbidities should also be diagnosed and treated.
