Links Between Granuloma Annulare,Necrobiosis Lipoidica Diabeticorum and Childhood Diabetes: A Matter of Time?

Abstract: Diabetes mellitus is associated with a range of dermatologic presentations, including granuloma annulare and necrobiosis lipoidica diabeticorum. Granuloma annulare occurs earlier than necrobiosis lipoidica diabeticorum and the association with diabetes mellitus is much weaker. We describe two children with diabetes who both developed granuloma annulare and later, necrobiosis lipoidica diabeticorum. We postulate that the early onset and transient nature of granuloma annulare, compared with the later onset and persistence of necrobiosis lipoidica diabeticorum, might account for the different apparent rates of association with diabetes mellitus.     

Erfolgreiche Therapie einer exulzerierten Necrobiosis lipoidica non diabeticorum mit Ciclosporin

Necrobiosis lipoidica is an inflammatory granulomatous skin disease of unknown etiology which is associated with diabetes mellitus in about 60% of the patients. In 15-35% of the affected patients painful ulcerations may occur after minimal trauma which can be extremely refractory to therapy. Because of the unknown pathomechanisms, current therapeutic options are limited. We report on a 68-year-old patient with an 18 year history of ulcerated necrobiosis lipoidica non diabeticorum of both lower limbs, which responded to systemic cyclosporine A. Based on this case, we discuss the role of cyclosporine A in patients with necrobiosis lipoidica in the context of the disease etiology.     

Transcutaneous measurement of oxygen and carbon dioxide pressure in necrobiosis lipoidica

Transcutaneous measurement of oxygen pressure (PcO2) and carbon dioxide pressure (PcCO2) was performed in nine patients with histologically confirmed necrobiosis lipoidica. None of the patients had diabetes mellitus. All measurements were taken at the lower leg. In each case, the atrophic center, the inflamed border, and the surrounding clinically normal skin of necrobiosis lipoidica were examined at 44 degrees C sensor temperature (maximal vasodilatation). Statistically significant hypoxia was found in the area of necrobiosis lipoidica, which was even more pronounced in the inflamed border. Inhalation of 100% oxygen provoked a marked increase in the PcO2 in the lesion, but the values were still significantly lower than in the normal skin. At the edge of the lesions the PcCO2 was significantly elevated. These findings support a vascular origin of necrobiosis lipoidica, involving reduced vascular perfusion combined with diffusion block.     

Erfolgreiche Behandlung einer Patientin mit therapierefraktärer, exulzerierter Necrobiosis lipoidica non diabeticorum mit Adalimumab

Necrobiosis lipoidica is a rare inflammatory granulomatous skin disease of unknown etiology which is associated with diabetes mellitus in about 60?% of the patients. In up to 30?% of these patients extremely painful and often hard-to-heal ulcerations occur in the course of the disease. We present a new therapeutic option using adalimumab to treat refractory ulcerated necrobiosis lipoidica non diabeticorum. The clinical efficacy of adalimumab probably reflects an immunomodulatory effect through the specific TNF-α inhibition which is one central aspect of the underlying inflammation. Thus, adalimumab could represent promising new treatment option, especially for patients with otherwise therapy-refractory ulcerated necrobiosis lipoidica.     

Juvenile,insulin‐dependent diabetes mellitus,type 1‐related dermatoses

Juvenile insulin‐dependent diabetes mellitus type 1 (IDDM) is a well‐recognized worldwide entity, the significance of which has increased because of its recent upsurging trends, warranting attention on variety of its clinical expressions, in particular, pertaining to skin, an aspect seldom taken cognizance of. Hence an endeavour to recap the related dermatoses, such as limited joint mobility syndrome including sclerodermoid (scleroderma–like) changes, xerosis, necrobiosis lipoidica diabeticorum, granuloma annulare, diabetic foot syndrome, has been made. Complexities relating to the recently explored issues of atopic dermatitis and drug hypersensitivity syndrome have also been covered adequately. In addition, the current concepts of the physiopathology of type 1 diabetes‐related dermatoses are briefly recapitulated for clarity.     

Sarcoidosis with extensive cutaneous ulceration. Unusual clinical presentation

A 70-year-old white woman with sarcoidosis and insulin-resistant diabetes mellitus presented with extensive cutaneous ulcerations. Both the cutaneous lesions and the systemic features of sarcoidosis showed a dramatic improvement during oral corticosteroid therapy. When extensive cutaneous ulcerations are present, it is important to consider sarcoidosis, as these may be the only presenting sign of the disease. Unlike ulcerated necrobiosis lipoidica diabeticorum, sarcoidal ulcerations may respond well to treatment with oral corticosteroids.     

Perforating necrobiosis lipoidica in a girl with type 1 diabetes mellitus: a new case reported

Necrobiosis lipoidica is an idiopathic dermatological condition that is strongly associated with diabetes mellitus. It is more commonly seen in women than men. The average age of onset is 30-40 years. Necrobiosis Lipoidica diabeticorum is an extremely rare finding in childhood diabetes. We describe the case of a 13-year-old girl who has had type 1 diabetes mellitus since she was 8 years old. The patient presented with 2 well-defined, persistent plaques with a depressed central area and elevated purple peripheral ring, one on the right thigh and the other over the lateral left leg. Histopathologic evaluation of the patient's biopsy confirmed the diagnosis of necrobiosis lipoidica with transfollicular elimination. Our patient is the second pediatric case described with perforating necrobiosis lipoidica. We review the literature and discuss clinical features, several complications, and the most recent treatment options for necrobiosis lipoidica in diabetic children.     

Necrobiosis lipoidica diabeticorum with cholesterol clefts in the differential diagnosis of necrobiotic xanthogranuloma

The histopathologic findings in 331 cases of necrobiosis lipoidica diabeticorum seen during a 50-year period were reviewed. Three cases showing cholesterol cleft formation were found. All 3 cases were associated with severe diabetes mellitus. The differential diagnosis of importance is necrobiotic xanthogranuloma. Common features included extensive hyaline necrobiosis and foreign-body giant cells. Atypical and Touton-type giant cells are more common in necrobiotic xanthogranuloma. Vascular changes in necrobiotic xanthogranuloma may include granulomatous involvement of muscular walls with thrombosis. Explanations for cholesterol cleft formation are offered. When cholesterol clefts are seen in biopsy specimens of necrobiosis, necrobiotic xanthogranuloma must be ruled out. In addition, when found in necrobiosis lipoidica diabeticorum, these clefts may imply diabetes mellitus with complications.     

Necrobiosis lipoidica

A 69-year-old patient presented with different skin lesions all of which belonged to group of necrobiosis lipoidica. The initial histologic diagnosis was actinic granuloma O??Brien. A subsequent biopsy was interpreted as granulomatous necrobiosis lipoidica. The history of these necrobiotic variants is reviewed and exemplarily depicted with this case. Necrobiosis lipoidica is part of the spectrum of granulomatous skin disorders. Although its etiology is unclear, an association with diabetes mellitus is often discussed. Multiple therapeutic options exist, but standardized guidelines for treatment are missing.     

Necrobiosis lipoidica. Variants on a theme

A 69-year-old patient presented with different skin lesions all of which belonged to group of necrobiosis lipoidica. The initial histologic diagnosis was actinic granuloma O'Brien. A subsequent biopsy was interpreted as granulomatous necrobiosis lipoidica. The history of these necrobiotic variants is reviewed and exemplarily depicted with this case. Necrobiosis lipoidica is part of the spectrum of granulomatous skin disorders. Although its etiology is unclear, an association with diabetes mellitus is often discussed. Multiple therapeutic options exist, but standardized guidelines for treatment are missing.

A systematic review of the relationship between glycemic control and necrobiosis lipoidica diabeticorum in patients with diabetes mellitus

The association of specific skin disorders with diabetes mellitus (DM) has been well established. Current literature suggests that approximately 30–91% of patients with diabetes will experience at least one cutaneous manifestation of this systemic disease in their lifetime. To date, there are limited articles summarizing the link between necrobiosis lipoidica diabeticorum (NLD) prognosis and glycemic control in patients with diabetes. The objective of the study is to summarize and appraise the available evidence assessing the relationship between glycemic control and NLD. A literature search was conducted based on MEDLINE (1946–2015), EMBASE (1980–2015), Google Scholar, and PubMed for publications that described the results of diabetes control and NLD. Further studies were identified from bibliographies of all relevant studies, gray literature, and annual scientific assemblies. All studies investigating the relationship between DM (type 1 and type 2) management and NLD were included. Two reviewers independently extracted data including demographics, type of diabetes management measures (glucose, HbA1c, insulin), comorbidities, and outcome. A total of 622 studies were identified, and 10 studies met the inclusion and exclusion criteria: two case series and eight case reports. Of the 24 patients with NLD, 13 patients reported resolution of NLD after implementing various methods of glycemic control (diabetic diet consisting of 1600 kcal/day [1 patient], insulin regimen [3 patients], and pancreatic transplantation [9 patients]). Glycemic control may have a role in influencing the prognosis of necrobiosis lipoidica in patients with diabetes; however, there is currently insufficient evidence to support or refute this claim.     

Necrobiosis lipoidica of the glans penis

We report a 65-year-old diabetic man with necrobiosis lipoidica occurring on the glans of penis. He was initially seen with chronic ulcerative balanitis that eventually healed with strict control of diabetes mellitus, cystostomy, and pentoxifylline, leaving heavily depressed scars. Penile necrobiotic palisading granulomas include necrobiosis lipoidica and granuloma annulare. On the basis of the literature review, these 2 diseases manifest different skin lesions.     

Dermatological care of the diabetic foot

Approximately 30% of patients with diabetes mellitus will have disease-related dermatological problems. Dry skin can be associated with autonomic neuropathy and may be fragile, promoting bacterial invasion. Any potentially infected 'diabetic foot' must be taken seriously, and non-painful deep sepsis suspected if there is evidence of sensory loss. Consideration should be given to eliminating nasal carriage of staphylococci if recurrent superficial sepsis occurs in the presence of poor diabetic control. Fungal infections, both of skin and nails, are common but usually not serious in the absence of immunosuppression. Treatment with topical antifungals may need to be combined with systemic therapy for successful eradication. Systemic antifungal therapy should be carefully considered as treatment needs to be prolonged and is potentially toxic, particularly in individuals with diabetes mellitus who often have co-morbidities. Varicose eczema should be treated by physical therapies intended to improve venous return and prevent peripheral edema and tissue injury. Allergic dermatitis is commonly associated with topical treatments and other sensitizers. Many reactions are not apparent from history, and patch testing for sensitivity is recommended. There are several diabetes mellitus-specific conditions that dermatologists must be aware of, including, necrobiosis lipoidica diabeticorum, granuloma annulare, diabetic dermopathy (spotted leg syndrome or shin spots), diabetic bullae (bullosis diabeticorum), and limited joint mobility and waxy skin syndrome. Ulceration, due to varying combinations of peripheral vascular disease and sensory neuropathy, is the province of the specialist team dealing with the diabetic foot and should ideally be referred to an appropriate multidisciplinary team.     

Necrobiosis Lipoidica-like Skin Lesions in Systemic Sarcoidosis

A 62-year-old woman with systemic sarcoidosis developed erythematous plaques on her lower legs. Clinically, two kinds of skin lesions were distinguished; one type formed brownish-red plaques with induration suggesting plaque-type skin sarcoid, and the other formed purplish erythematous plaques with atrophic centers resembling necrobiosis lipoidica. In spite of this clinical appearance, a biopsy specimen from one of the latter lesions revealed typical skin sarcoid histology composed of discrete non-caseating granulomas, while that from one of the other lesions showed necrobiotic changes of collagen bundles surrounded by epitheloid histiocytes and foreign-body giant cells. Because cutaneous involvement of sarcoidosis may mimic necrobiosis lipoidica clinically and/or histologically, we diagnosed her skin lesions as necrobiosis-like skin sarcoid.     

Necrobiosis lipoidica over appendectomy scar in a patient with morphea of the breast

Morphea is a sclerosing skin disease that may be clinically confused with a carcinoma when it involves the breast. It has been described in association with earlier radiotherapy and with silicone breast implants. We describe the case of a woman with morphea of the breast who developed necrobiosis lipoidica over the scar of an appendectomy performed 38 years earlier. Necrobiosis lipoidica over surgical scars is infrequently found in the literature. We review the published cases and discuss the association of necrobiosis lipoidica with morphea.     

Regional Dermatoses in the African Black

Abstract: In a survey of dermatitis diagnosed in Lagos, Nigeria, dermatitis cruris pustulosa et atrophicans, lichen planus, lichen simplex chronicus, pretibial achromic lesions, and ichthyosiform dry skin are very common; necrobiosis lipoidica diabeticorum and diabetic dermopathy are moderately common; sporotrichosis and lichen amyloidosis are occasionally seen, but erythema nodosum is rare.     

Necrobiosis-lipoidica-like skin manifestation in lymphomatoid granulomatosis (Liebow)

A 58-year-old man developed 3 indurative erythematous lesions like necrobiosis lipoidica on the right lower leg. He had had similar cutaneous lesions 1.5 years previously. These had been surgically excised, and a histologic diagnosis of necrobiosis lipoidica was made at another hospital. He was diagnosed as having lymphomatoid granulomatosis by lung biopsy in our hospital. Nasal involvement was confirmed in later examinations and the skin lesions were also considered to be the cutaneous manifestation of lymphomatoid granulomatosis. This outlines that cutaneous manifestations may allow early diagnosis of lymphomatoid granulomatosis.     

Necrobiosis Lipoidica Diabeticorum

Necrobiosis lipoidica is a skin disorder with an interesting predisposition for areas of trauma such as the anterior shins. In this report a patient with diabetes mellitus and generalized neerobiosis lipoidica diabeticorum with localization in surgical scars is described. A brief review of other skin disorders occurring in scars is also included.
