Erythema elevatum diutinum complicated by rheumatoid arthritis

Annular vasculitic lesions

Vasculitic skin findings may present with annular morphologies. This group of conditions consists of capillaritis, such as pigmented purpuric dermatoses, and vasculitis, which is often classified by the affected vessel size. Annular vasculitic lesions may be the presenting sign of systemic disease, thus requiring thorough exploration to reach an accurate diagnosis and guide proper disease management. Herein we review the clinical presentation, histopathology, and treatments for cutaneous vasculitic disease that may present with annular lesions.

Erythema elevatum diutinum: a case report and review of literature

Erythema elevatum diutinum (EED) is a rare cutaneous leukocytoclastic vasculitis thought to be related to increased levels of circulating antibodies. It has been shown to be associated with HIV infection, tuberculosis, as well as various autoimmune diseases. A retrospective review of all cases of EED indexed in PubMed between 1990 and 2014 was performed. Inclusion criteria for articles was availability of full text in English and a biopsy-confirmed diagnosis of EED. All other articles were excluded. Cases were stratified by age and anatomic location of the lesions. Treatment response was coded as "complete," "partial," and "none." A total of 133 cases of EED with 381 lesions detailed in case reports and case series were included. Twenty-one cases were associated with HIV. Of 47 patients with reported paraproteinemias, IgA paraproteinemia was found in 57.45%, IgG paraproteinemia in 29.8%, IgM paraproteinemia in 10.6%, and IgD paraproteinemia in 2.1% of cases. Of 40 (30.1%) patients with reported comorbid autoimmune disease, rheumatoid arthritis was associated with 10 cases. Cancer was found to be associated with 9.77% of cases. Seventy-five patients were treated with dapsone, with 36 (48%) achieving complete treatment response, 24 (32%) achieving partial response, and seven (9.3%) achieving no response. Keeping the clinical associations of EED in mind, especially malignancy, is critical in management of the disease. More structured studies need to take place in order to fully define the mechanisms and strength of these associations.

Successful surgical treatment of advanced erythema elevatum diutinum

Erythema elevatum diutinum is a rare, chronic cutaneous vasculitis that presents with plaques or nodules on the extensor surfaces of extremities. Although the exact pathogenesis is unknown, patients usually have an underlying systemic medical problem such as malignancy, autoimmune disease or HIV. Management of the cutaneous manifestations is aimed at controlling the underlying disease process, in addition to medical therapy directed at suppressing the lesions. The difficult case of a 60-year-old man, who was not a candidate for medical therapy but has undergone successful surgical therapy of this rare disease for 10 years, is presented.

Erythema elevatum diutinum in systemic lupus erythematosus

Erythema elevatum diutinum (EED) is a rare chronic form of leukocytoclastic vasculitis with unknown etiology. EED has been described in association with hematological malignancies, infections and a number of rheumatological diseases. We report a patient with systemic lupus erythematosus (SLE) who presented with intermittent attacks of tender nodules and plaques on the shins and ankles for 6 months. Skin biopsy confirmed the diagnosis of EED. Treatment with dapsone resulted in complete resolution of the skin lesions. EED is rarely reported in SLE, and its presentation and treatment is reviewed.

Erythema Elevatum Diutinum

Erythema elevatum diutinum (EED) is a chronic cutaneous vasculitis occurring in association with a variety of conditions including autoimmunity, infectious disease, and hematological abnormalities. The role of associated medical problems is controversial, and the exact pathogenesis of EED is unknown. A series of six cases is reported. The typical clinical presentation was that of erythematous papules and plaques involving the extensor surfaces of the extremities. Histologically, a spectrum from leukocytoclastic vasculitis to vessel occlusion and dermal fibrosis was seen. The lesions of EED have many mimics clinically and histologically. Establishing the diagnosis of EED is important so appropriate screening for associated conditions can ensue. The vascular endothelium of EED stains positive for CD31, CD34, VEGF, and factor VIIIa and negative for factor XIIIa, TGFB, and LANA, a reaction pattern that does not distinguish it from similar appearing lesions. Thus, the chronic and recurrent nature of EED is the primary means of distinguishing it from entities that are clinically and histologically similar.

Erythema elevatum diutinum as a first clinical manifestation for diagnosing HIV infection: case history

CONTEXT

Erythema elevatum diutinum is a chronic and rare dermatosis that is considered to be a variant of leukocytoclastic vasculitis. It is probably mediated by immune complexes. It is generally associated with autoimmune, neoplastic and infectious processes. Recently, it has been added to the group of specific dermatoses that are associated with HIV.

CASE REPORT

We report on the case of a patient who had erythema elevatum diutinum as the first clinical evidence for diagnosing HIV infection. Dapsone was used in the treatment of this patient, and partial regression of the lesions was achieved within 15 days, even before anti-retroviral therapy was prescribed.

CONCLUSION

When there is a diagnosis of erythema elevatum diutinum, HIV infection should be investigated, especially in atypical and exacerbated clinical manifestations.

Erythema Elevatum Diutinum in the Setting of Connective Tissue Disease and Chronic Bacterial Infection

Erythema elevatum diutinum (EED) is a rare and chronic cutaneous leukocytoclastic vasculitis. It is predominantly seen on the extensor surfaces of the extremities. Although a specific cause is largely unknown, EED has been noted to occur in association with a wide variety of diseases. A 28-year-old man with systemic lupus erythematosus (SLE) and a 53-year-old woman with an overlap syndrome of rheumatoid arthritis and polymyositis are presented. Both patients developed EED in the setting of chronic recurrent bacterial infections. Patients with a connective tissue disease are at increased risk for such infections secondary to immunosuppression, either from the disease itself or secondary to immunosuppressive therapy. EED has been independently reported to occur in the setting of connective tissue disease as well as in the setting of chronic infection. Our patients had both of these underlying conditions, which are known to predispose patients to immune complex-mediated vasculitides, in this case EED. One patient's EED responded to treatment of the SLE and the other improved, as has been previously reported with dapsone.

Late-stage nodular erythema elevatum diutinum

Erythema elevatum diutinum (EED) is a rare chronic vasculitic process of unknown etiology that presents as bilateral, symmetrical, periarticular, red-brown papules and plaques, often over dorsa of joints. Early histologic changes are characterized by leukocytoclastic vasculitis. With chronicity, the lesions develop dense neutrophilic infiltrate and fibrosis. We describe an unusual case of late-stage nodular EED present for 35 years in a seronegative 75-year-old man. Asymptomatic papules and plaques measuring from 0.7 to 9.0 cm were seen over the interphalangeal joints, elbows, knees, and ankles. The histologic findings were characterized by predominant concentric fibrosis that formed well-circumscribed dermal and subcutaneous nodules. Awareness of this unusual presentation of EED helps to avoid misdiagnosis as cutaneous neoplasms.

Cutaneous vasculitis: a review

As the skin is commonly involved in systemic vasculitic disorders as well as those hypersensitivity states whose expression is largely skin-confined, cutaneous vasculitic lesions offer a window to diagnosis and a ready source of accessible tissue for biopsy. In this review, we discuss the pathologic manifestations of chronic vasculitic syndromes such as granuloma faciale and erythema elevatum diutinum; IgA-associated vasculitis including Henoch-Schonlein purpura; vasculitis seen in the setting of cryoglobulinemia and hypergammaglobulinemia of Waldenstrom, hereditary deficiencies of complement, and IgA deficiency; those leukocytoclastic vasculitides resulting from hypersensitivity reactions to drug, chemical and foodstuff ingestion; and those vasculitides seen in patients with systemic diseases such as polyarteritis nodosa, rheumatoid arthritis, mixed connective tissue disease, systemic lupus erythematosus, Sjogren's syndrome, relapsing polychondritis, Behcet's disease, Wegener's granulomatosis, and allergic granulomatosis of Churg and Strauss.

The spectrum of cutaneous lesions in rheumatoid arthritis: a clinical and pathological study of 43 patients

INTRODUCTION

Rheumatoid arthritis (RA) is an idiopathic arthropathy syndrome that has a propensity to affect the small joints of the hands and feet with extra-articular manifestations comprising skin lesions, neuropathy, pericarditis, pleuritis, interstitial pulmonary fibrosis and a systemic polyarteritis nodosa (PAN)-like vasculitic syndrome. The most widely recognized skin lesion is the rheumatoid nodule. Other skin manifestations are poorly defined.

MATERIALS AND METHODS

Using a natural language search of the authors' outpatient dermatopathology databases, skin biopsies from 43 patients with RA were selected for retrospective analysis in an attempt to define the dermatopathological spectrum of RA and its clinical correlates.

RESULTS

The biopsies were categorized by the dominant histologic pattern, recognizing that in most cases there were additional minor reaction patterns. Palisading and/or diffuse interstitial granulomatous inflammation was the dominant pattern seen in 21 patients; the lesions included nodules, plaques and papules with a predilection to involve skin over joints. Besides interstitial histiocytic infiltrates and variable collagen necrobiosis, these cases also showed interstitial neutrophilia, vasculitis and pauci-inflammatory vascular thrombosis. The dominant morphology in 11 other patients was vasculopathic in nature: pauci-inflammatory vascular thrombosis, glomeruloid neovascularization, a neutrophilic vasculitis of pustular, folliculocentric, leukocytoclastic or benign cutaneous PAN types, granulomatous vasculitis, and lymphocytic vasculitis and finally occlusive intravascular histiocytic foci for which the designation of "RA-associated intravascular histiocytopathy" is proposed. Rheumatoid factor (RF) positivity and active arthritis were common in this group, with anti-Ro and anticardiolipin antibodies being co-factors contributing to vascular injury in some cases. Immunofluorescent testing in three patients revealed dominant vascular IgA deposition. In nine patients, the main pattern was one of neutrophilic dermal and/or subcuticular infiltrates manifested clinically as urticarial plaques, pyoderma gangrenosum and panniculitis.

CONCLUSIONS

The cutaneous manifestations of RA are varied and encompass a number of entities, some of which define the dominant clinical features, such as the rheumatoid papule or subcutaneous cords, while others allude to the histopathology, i.e. rheumatoid neutrophilic dermatosis. We propose a more simplified classification scheme using the adjectival modifiers of "rheumatoid-associated" and then further categorizing the lesion according to the dominant reaction pattern. Three principal reaction patterns are recognized, namely extravascular palisading granulomatous inflammation, interstitial and/or subcuticular neutrophilia and active vasculopathy encompassing lymphocyte-dominant, neutrophil-rich and granulomatous vasculitis. In most cases, an overlap of the three reaction patterns is seen. Co-factors for the vascular injury that we believe are integral to the skin lesions of RA include RF, anti-endothelial antibodies of IgA class, anti-Ro and anticardiolipin antibodies.
