Predictive factors for anti-MDA5 antibody in patients with dermatomyositis: a retrospective multicenter study.

Background And Objectives: Melanoma differentiation-associated gene 5 antibody (anti-MDA5) in dermatomyositis (DM) is associated with rapidly progressive interstitial lung disease and poor prognosis. Early diagnosis is key to improving the prognosis of these patients. The aim was to confirm cutaneous characteristics in patients with anti-MDA5 dermatomyositis and to explore new diagnostic markers for the presence of anti-MDA5 (anti-MDA5 ).

Prognostic factors for satellitosis or in-transit metastasis in cutaneous squamous cell carcinoma: A multicentric cohort study.

Background: Satellitosis or in-transit metastasis (S-ITM) has clinical outcomes comparable to node-positivity in cutaneous squamous cell carcinoma (cSCC). There is a need to stratify the risk groups.

Objective: To determine which prognostic factors of S-ITM confer an increased risk of relapse and cSCC-specific-death.

Neutrophilic Infiltrates in Panniculitis: Comprehensive Review and Diagnostic Algorithm Proposal.

Neutrophilic infiltrates in panniculitis can be seen in different clinical-pathological entities. There are a "mostly neutrophilic inflammatory infiltrate" in some entities classically defined as neutrophilic panniculitis and already included in algorithms, such as enzymatic panniculitis, infective and factitial ones, erythema induratum, or subcutaneous Sweet syndrome, but there are also other panniculitis where neutrophils are frequently observed such as panniculitis associated with inflammatory bowel disease or rheumatoid arthritis, or drug-induced panniculitis associated with BRAF inhibitors, and finally, some panniculitis are better classified in other panniculitides groups but may present with neutrophil-rich variants, such as the neutrophil-rich subcutaneous fat necrosis of the newborn. We review the main clinical and histopathological features of most of these panniculitides and construct a diagnostic algorithm including these diseases.

The use of tocilizumab in the treatment of refractory eosinophilic fasciitis: a case-based review.

Eosinophilic fasciitis (EF) is a rare disorder involving chronic inflammation of the fascia and connective tissue of unknown aetiology and poorly understood pathogenesis. We present the case of a 60-year-old man diagnosed with eosinophilic fasciitis with extensive cutaneous involvement and severe functional repercussion, which appeared weeks after suffering from pneumonia due to Legionella pneumophila. The patient did not experience any clinical response with high-dose corticosteroids, subcutaneous methotrexate, and intravenous immunoglobulins.

[MALLEOLAR ULCERS ASSOCIATED TO HYDROXYUREA TREATMENT].

Introduction: Hydroxyurea (HU) is an antineoplastic drug used in chronic myeloproliferative disorders. In this article we will go into detail about the rare but serious appearance of lower limb ulcers in relation to HU treatment.

Methodology: Two simultaneous cases are presented, both from patients with lower limb torpid lesions unresponsive to conventional treatments.
