BACKGROUND: Mucin 13 (MUC13) is a cell surface glycoprotein aberrantly expressed in a variety of epithelial carcinomas. Thus far, the role of MUC13 in various diseases remains elusive. To the best of our knowledge, this is the first study to examine the potential of MUC13 as a serum biomarker in a variety of carcinomas and other conditions. METHODS: We developed a recombinant MUC13 protein, mouse monoclonal antibodies and enzyme immunoassay (ELISA) for MUC13. We used this assay to measure MUC13 levels in the supernatants of cancer cell lines and a large cohort of serum samples from healthy and diseased individuals...

The influenza vaccination is recommended annually for protection against influenza infection. Adults over 65 years of age are especially vulnerable to complications from influenza infection; in addition, they constitute the largest group of influenza vaccination recipients each year. Cutaneous leukocytoclastic vasculitis involves inflammation of small vessel walls by neutrophils. An 88-year-old man with a history of idiopathic pulmonary fibrosis who developed bullous cutaneous leukocytoclastic vasculitis 14 days after receiving the influenza vaccine is described and the characteristics of influenza-associated cutaneous leukocytoclastic vasculitis in older individuals are reviewed...

BACKGROUND: Tularaemia is a zoonotic infectious disease caused by Francisella tularensis, an aerobic, uncapsulated, gram-negative coccobacillus. Several case reports have appeared on the dermatological manifestations of tularaemia, but relatively few longer-term studies are available. AIM: To identify skin features of tularaemia that aid in its diagnosis. METHODS: In total, 168 patients (68 male, 100 female) diagnosed with tularaemia were retrospectively examined...

We report a case of a middle-aged male who presented with pyrexia of unknown origin, oral ulcers, rash and bicytopenia. His past medical history included unexplained proteinuria, infertility and joint pain. Initial workup showed a large retroperitoneal soft tissue mass, which has appeared stable for 10 years. He subsequently developed neuropsychiatric symptoms with imaging findings of meningoencephalitis. Concurrent investigations showed elevated ANA, anti-double-stranded DNA (dsDNA) and ESR levels, as well as low complement levels...

BACKGROUND: Henoch-Schönlein purpura (HSP) is a common vasculitis in childhood characterized by purpura, arthritis, abdominal pain and renal involvement. However, bullous HSP is a rare cutaneous manifestation, and a few cases have been reported. CASE PRESENTATION: Herein, we report a 15-year-old male with bullous HSP who presented with severe abdominal pain and hemorrhagic bullous lesions over his lower extremities. He was treated with corticosteroid, after which the symptoms improved dramatically...

Reflex sympathetic dystrophy is a subtype of complex regional pain syndrome, a condition characterized by persistent post-injury extremity pain. Temperature and sweating changes, edema, mobility changes, and a variety of hair, nail, and skin sequelae have been described. Only 23 articles published since 1990 describe dermatologic changes in CRPS. Given this paucity of literature, we present a case to further elucidate cutaneous manifestations of CRPS. Our patient is a 52-year-old Caucasian woman with a 19-year history of reflex sympathetic dystrophy who has presented with several dermatologic complaints...

BACKGROUND: Hepatitis C virus (HCV)-associated mixed cryoglobulinaemia is the manifestation of an inflammation of small and medium-sized vessels produced by a pathogenic IgM with rheumatoid factor activity generated by an expansion of B-cells. The immune complexes formed precipitate mainly in the skin, joints, kidneys or peripheral nerve fibres. Current therapeutic approaches are aimed at elimination of HCV infection, removal of cryoglobulins and also of the B-cell clonal expansions. The optimal treatment for it has not been established...

Granulomatosis with polyangiitis (GPA) is a systemic necrotizing small vessel vasculitis associated with circulating anti-neutrophil cytoplasmic antibodies (ANCAs). Skin manifestations, mostly represented by palpable purpura, papulonodular lesions and livedo reticularis, are present in up to 50% of the cases. Ulcerations with undermined, raised erythematous-violaceous border resembling pyoderma gangrenosum (PG) have rarely been reported as skin involvement in GPA. The presence of circulating ANCAs with a cytoplasmic labelling pattern, the involvement of internal organs, particularly of the lung, and the absence on histology of a mainly neutrophilic infiltrate in early phases of the cutaneous lesions may be regarded as clues to rule out true PG and confirm the diagnosis of GPA skin ulcerations simulating PG...

Inflammatory, infectious, and neoplastic processes can all occur in prior areas of herpes infection (postherpetic isotopic response [PHIR]). Postzoster granulomatous dermatitis is among the most frequently encountered PHIR, but the exact pathogenesis has not been fully elucidated. Rarely, multiple diseases manifest concurrently in a PHIR. We report a case of cutaneous chronic lymphocytic leukemia (CLL) with an associated granulomatous dermatitis and medium-vessel vasculitis occurring simultaneously at the site of prior herpes zoster...

The complement system is a fundamental part of the innate immune system, playing a crucial role in host defense against various pathogens, such as bacteria, viruses, and fungi. Activation of complement results in production of several molecules mediating chemotaxis, opsonization, and mast cell degranulation, which can contribute to the elimination of pathogenic organisms and inflammation. Furthermore, the complement system also has regulating properties in inflammatory and immune responses. Complement activity in diseases is rather complex and may involve both aberrant expression of complement and genetic deficiencies of complement components or regulators...

Anti-neutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV) and cryoglobulinemic vasculitis (CV) rarely coexist. An 83-year-old woman was admitted with rapidly progressive renal failure, gastrointestinal hemorrhage and purpura with myeloperoxidase (MPO) -ANCA positivity and cryoglobulinemia. Despite intensive immunosuppressive treatment, she died of aspergillus pneumonia. Autopsy revealed necrotizing crescentic glomerulitis in the majority of the glomeruli, accompanied by partially membranoproliferative-like glomerular changes...

Cutaneous leukocytoclastic vasculitis arises from immune complex deposition and dysregulated complement activation in small blood vessels. There are many causes, including dysregulated host response to infection, drug reactions, and various autoimmune conditions. It is increasingly recognised that some monogenic autoinflammatory diseases cause vasculitis, although genetic causes of vasculitis are extremely rare. We describe a child of consanguineous parents who presented with chronic cutaneous leukocytoclastic vasculitis, recurrent upper respiratory tract infection, and hypocomplementaemia...

Deficiency of adenosine deaminase 2 (DADA2) is a recently described autoinflammatory disorder. Genetic analysis is required to confirm the diagnosis. We aimed to describe the identifying symptoms and genotypes of patients referred to our reference centres and to improve the indications for genetic testing. DNA from 66 patients with clinically suspected DADA2 were sequenced by Sanger or next-generation sequencing. Detailed epidemiological, clinical and biological features were collected by use of a questionnaire and were compared between patients with and without genetic confirmation of DADA2...

Renal cell carcinoma is historically known as the 'great masquerader' with 40% of patients experiencing a paraneoplastic syndrome. Translocation carcinoma represents one-third of renal cancer in paediatric patients but less than 3% of renal cancers in patients aged 18-45 years where the clinical course is often rapidly terminal. There are less than 10 reported cases of leucoclastic vasculitis associated with clear cell carcinoma reported in the literature and 10 case reports of translocation carcinoma in adults...

Skin is commonly affected by vasculitic process and often subjected to biopsy. Cutaneous vasculitis can be either primary or part of a systemic vasculitic process. This study was conducted to evaluate the diagnostic utility of direct immunofluorescence (DIF) in determination of etiology of cutaneous vasculitis. All histologically proven cases of cutaneous vasculitis over the past two and half years were retrospectively analyzed along with their clinical and DIF findings (IgG, IgA, IgM, and C3). Within this study period, a total of 198 cases of small-vessel vasculitis were diagnosed based on skin biopsy and DIF findings...

Inflammatory dermatoses encompass a variety of histologic patterns that affect different portions of the skin. In spongiotic, psoriasiform, lichenoid, pityriasiform, and blistering disorders, there are predominately epidermal and junctional activities with variable superficial dermal inflammation. Hypersensitivity reactions can show either epidermal or mostly dermal changes depending on whether the exposure of the exogenous allergen occurs through an external or internal route, respectively. Exceptions include erythema multiforme and Stevens-Johnson syndrome/toxic epidermal necrolysis, where the etiology is often due to infection or ingested medications, but the histologic features are almost exclusively confined to the epidermis and dermoepidermal junction...

Aryl hydrocarbon receptor (AhR), which was discovered as a receptor for environmental concomitants, plays an important role widely in the immune system. In this study, we assessed AhR involvement in immune complex (IC)-mediated vascular injury by examining reverse-passive Arthus reaction in AhR heterozygous knockout (AhR+/- ) mice. In cutaneous Arthus reaction, dermal edema was severer in AhR+/- mice than in WT mice. The number of infiltrating neutrophils and mRNA expression levels of CXCL1 and IL-6 were also increased in AhR+/- mice...
