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. Read More

Necrobiosis lipoidica (NL) is a granulomatous inflammatory skin disease strongly associated with diabetes mellitus (DM). Red-brown papules expanding into plaques with erythematous indurated borders on the lower extremities are characteristic of NL. Diagnosis is made clinically; however, biopsy of lesions confirms the diagnosis. Read More

A series of clinical research projects conducted over the past 40 years, all of which were informed by clinical observation or discussions with people with diabetes and staff colleagues are described in this review. A study of necrobiosis lipoidica diabeticorum confirmed that this rare skin complication occurs predominantly in young women with Type 1 diabetes and other microvascular complications. Biopsies of necrobiotic lesions showed destruction of superficial nerve fibres by inflammatory tissue, which likely causes the sensory loss in lesions that is pathognomonic of the condition.

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.

Inflammatory granulomatous dermatitides include cutaneous sarcoidosis, necrobiosis lipoidica, granuloma annulare, and reactive granulomatous dermatitis. The etiopathogenesis of these disorders is not well understood; but the T helper 1 response mediated by interferon-gamma, tumor necrosis factor-alpha, and interleukin (IL) 1, 2, and 6 and the T helper 17 response mediated by IL-17 play a role. These inflammatory granulomatous disorders often have cutaneous manifestations in addition to extracutaneous manifestations or associations with systemic diseases. Read More

Objectives: Potassium iodide (KI) is a medication that has been used for decades in dermatology and it is mentioned as a treatment option in all major dermatology textbooks. Yet, there is little recent information on its efficacy. In our study, we wanted to retrospectively evaluate the therapy response to KI in our patients. Read More

We report the case of a 40-year-old African-American female with biopsy-proven pulmonary sarcoidosis who developed atrophic plaques on her shins, trunk, and scalp that were clinically and histologically consistent with necrobiosis lipoidica (NL). The lesions appeared 3 years after her diagnosis of sarcoidosis, and progressed despite chronic prednisone. Sarcoidosis and NL are granulomatous skin disorders reported to coexist in the same patient only 10 times in the literature. Read More

Although diagnosis of cutaneous granulomatous disorders (CGDs) is usually suspected based on morphologic findings, localization, and anamnestic data, clinical differentiation from each other and from similar dermatoses may be challenging. Recently, dermatoscopy has been demonstrated to be a useful tool for assisting the recognition of several CGDs. This article provides a current overview of the dermatoscopic features of the main noninfectious and infectious CGDs, including sarcoidosis, necrobiosis lipoidica, granuloma annulare, rheumatoid nodules, and leishmaniasis.

Cutaneous sarcoidosis is not an uncommon disorder, and the skin can be the sole manifestation in about 10% of patients. However, when the involved anatomical area of the cutaneous sarcoidosis is the scalp and it presents as a scarring alopecia, there is an increased risk of a systemic disease (1,2). A 79-year-old Caucasian male patient presented to our Institute with annular and painless plaques of the scalp, with variable diameter, showing a reddish and yellowish color (Figure 1, a). Read More

Successful management of patients with leg ulcers requires identification of the underlying etiology, with subsequent initiation of causal treatment, if feasible. Supplementary measures of first choice include stage-adjusted wound treatment, usually combined with compression therapy. The significance of systemic drugs has been the subject of controversial debate, depending on the underlying cause of the condition. Read More

Introduction: Necrobiosis lipoidica (NL) is a rare, treatment-resistant, granulomatous skin disease of unknown origin, frequently seen in patients with diabetes.

Methods: In this retrospective study we evaluated the long-term efficacy of methyl aminolaevulinate-based photodynamic therapy (MAL-PDT), including 80 treatments (70 conventional and 10 daylight PDT), on 65 unselected NL patients treated routinely in our clinic. Superficial curettage, avoiding skin oozing or bleeding, was performed prior to MAL application. Read More

Actinic granuloma (AG) manifests as annular plaques on sun-damaged skin. There remains no universal consensus on the nosology, etiology, or clinicopathologic criteria of AG as a distinct entity. Broadly, AG is characterized by granulomatous inflammation, multinucleated giant cells, elastophagocytosis, and the absence of mucin and necrobiosis. Read More

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. Read More

The link between the metabolic syndrome (MetS) and skin diseases is increasingly important, with new associations being discovered. The association between MetS and psoriasis or MetS and hidradenitis suppurativa is well known, although the relationship between MetS and various autoimmune or inflammatory diseases has only recently attracted interest. Some inflammatory skin diseases, such as vitiligo, scleredema, recurrent aphthous stomatitis, Behçet disease, rosacea, necrobiosis lipoidica, granuloma annulare, skin tags, knuckle pads, and eruptive xanthomas, have possible associations with MetS.

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. Read More

Chronic wounds often manifest as ulcers on the lower legs. The main causes of chronic leg ulcers are chronic venous insufficiency and/or peripheral arterial occlusive disease in approximately 80% of all patients. However, there are also numerous other potentially relevant factors which can cause or almost impede the healing of chronic leg ulcers. Read More

The palisading granulomatous dermatitides comprise a group of different skin diseases with similar histomorphologic forms of granuloma in the skin. Histopathologically characteristic are areas in the reticular dermis and subcutaneous fat with degenerated bundles of collagen surrounded by histiocytes and multinucleate giant cells aligned in a palisade (necrobiotic granuloma). Within the center of palisaded granulomas, mucin or fibrin can be found. Read More
