A 28-year-old man with clinically and laboratory diagnosed anti-PL-12 anti-synthetase syndrome (AS) in 2009 developed cutaneous lupus lesions, discoid lupus lesions, and sclerodacytly with finger-tip ulcerations four years following his AS diagnosis. Laboratory tests including +ANA, +anti-dsDNA antibody, +anti-Smith antibody, and +anti-RNP antibody in 2014 confirmed the diagnosis of progression to an overlap syndrome including systemic lupus erythematosus. The patient now also has clinical findings (sclerodacytly, Raynaud phenomenon, finger-tip ulcerations) consistent with scleroderma overlap...

An adult female beagle (Canis lupus familiaris) used in a model of doxorubicin-induced cardiomyopathy presented with epithelial desquamation on the shoulders and ventrum after receiving the 8th weekly intravenous dose of the free form of doxorubicin (20 mg/m2; total accumulation, 160 mg/m2). The lesions were empirically treated with topical disinfectants and topical and systemic antibiotics. Despite treatment, the lesions progressed and ulcerated. Bacterial culture revealed Staphylococcus aureus, but trichogram, skin scraping, and fungal culture were negative for microorganisms...

Propylthiouracil (PTU) is a commonly used medication for the treatment of hyperthyroidism. PTU is known to cause different adverse reactions including autoimmune syndromes. PTU-induced autoimmune syndromes can be classified into drug-induced lupus or drug-induced vasculitis. Differential diagnoses could be very challenging. PTU-induced vasculitis is more common than PTU-induced lupus, and has a higher risk of morbidity and mortality. Usually it is limited to the skin in a form of cutaneous leukocytoclastic vasculitis, but may also affect organs including kidneys and lungs...

BACKGROUND: Polymorphic light eruption (PLE) is the most common autoimmune photodermatosis. Plasmacytoid dendritic cells (PDCs) are important mediators of innate anti-microbial immunity involved in the pathogenesis of many inflammatory skin diseases. In addition to PDCs, regulatory T cells (Tregs) are involved in controlling inflammation and adaptative immunity in skin by their immunosoppressive capacity. OBJECTIVE: The aim of the present study was to investigate the presence of PDCs and Tregs in photoexposed skin from PLE compared to healthy skin...

A variety of autoantibodies has been involved in the pathogenesis of systemic lupus erythematosus (SLE), some of which are well known and applied as disease biomarkers. This study aimed to determine the prevalence of a novel autoantibody, anti-tubulin-α-1C, in patients with SLE and investigate its clinical significance. Anti-tubulin-α-1C autoantibody levels were determined by enzyme-linked immunosorbent assay (ELISA) in 128 SLE patients, 38 primary Sjögren's syndrome (pSS) patients, and 106 healthy controls (HCs)...

Regulatory T cells (Tregs) represent a cell type that promotes immune tolerance to autologous components and maintains immune system homeostasis. The abnormal function of Tregs is relevant to the pathogenesis of several skin diseases like psoriasis, atopic dermatitis, systemic lupus erythematosus, cutaneous T-cell lymphomas, and skin cancer and is also important in rheumatoid arthritis, diabetes and other autoimmune diseases. In this review, we will summarize the role of mutations and/or polymorphisms of genes involved in Tregs development, and functions in the pathogenesis of selected skin diseases...

The American College of Rheumatology (ACR) classification criteria for lupus and Systemic Lupus International Collaborating Clinics (SLICC) criteria are designed to classify disease. However, they have become widely used as diagnostic criteria in clinical situations. Patients may be labelled as systemic lupus erythematosus (SLE) in their medical records, when in fact they have cutaneous lupus erythematosus (CLE) without systemic symptoms. We sought to investigate how many of our cutaneous lupus patients attending a dermatology lupus clinic were mislabelled as either CLE or SLE using the ACR and SLICC criteria...

BACKGROUND: Systemic lupus erythematosus (SLE) is a systemic autoimmune disease that affects different end organs, including skin and brain. We and others have previously shown the importance of macrophages in the pathogenesis of cutaneous and neuropsychiatric lupus. Additionally, autoantibodies produced by autoreactive B cells are thought to play a role in both the skin and central nervous system pathologies associated with SLE. METHODS: We used a novel inhibitor of Bruton's tyrosine kinase (BTK), BI-BTK-1, to target both macrophage and B cell function in the MRL-lpr/lpr murine model of SLE, and examined the effect of treatment on skin and brain disease...

Cutaneous vasculitides encompass a wide and heterogeneous group of diseases affecting skin blood vessels that are clinically characterized by polymorphic skin lesions, including in particular palpable purpura as well as urticarial and necrotic-ulcerative lesions, with possible, albeit rare, extracutaneous involvement. Cutaneous leukocytoclastic angiitis and urticarial vasculitis, which are the two prototypic and most common variants of this group, are usually idiopathic but may also be induced by different triggers, notably drugs and infections, or may manifest in association with systemic disorders, particularly lupus erythematosus...

Cutaneous lupus erythematosus (CLE) is a chronic-relapsing disease. It is defined as a LE localized to the skin without any significant systemic symptoms. Its annual incidence is of 4 cases per 100,000 persons with a prevalence of 73 cases per 100,000 persons. The etiology is unknown but it is considered as a prototype of autoimmune disease in which genetic factors (HLA), environmental factors (photo exposure and cigarette smoking) and pharmacological agents play an important role. The most accepted classification includes three clinical variants: acute (ACLE), subacute (SCLE) and chronic (CCLE)...

Renal involvement is common and heterogenous in connective tissue diseases and has a main influence on prognosis and mortality. In systemic lupus erythematosus proliferative glomerulonephritis is the most common manifestation, while in primary Sjogren's syndrome interstitial nephritis with tubular dysfunction is the predominant pathological feature. In systemic sclerosis the most serious renal manifestation is scleroderma renal crisis characterized by abrupt onset of hypertension and acute kidney injury associated with an increase in plasma renin activity...

Lupus erythematosus is a chronic autoimmune disease characterized by remissions and exacerbations. Accumulated evidence indicated that matrix metalloproteinases (MMPs) are upregulated in inflammatory cells of cutaneous lupus erythematosus (CLE); however, the activity levels of these proteases have remained uncharacterized. To elucidate the significance of MMP-2, MMP-9, and TIMP-1 in CLE pathogenesis, gelatin zymography was used to investigate pro and active levels of MMP-2 and MMP-9 in lesional and perilesional skin biopsies obtained from twenty-two CLE patients...

BACKGROUND: Hemophagocytosis is well known in cytotoxic cutaneous T-cell lymphomas (CTCLs), in which it may represent a sign of hemophagocytic lymphohistiocytosis syndrome (HLHS), and is also typical of cutaneous Rosai-Dorfman disease (cRDD) (without prognostic relevance). Only rarely, has cutaneous hemophagocytosis (CH) been described in other skin conditions. OBJECTIVE: To characterize the clinicopathologic features of CH in skin biopsy specimens from patients with conditions other than CTCL or cRDD...
