    Synovial cyst in juvenile idiopathic arthritis

    No full text
    Small synovial cysts are a common manifestation of juvenile idiopathic arthritis; large brachial cysts, however, are a rare sign of the disease and they must be differentiated from other soft tissue swelling which are not related to articular involvement. We describe the case of three children with juvenile idiopathic arthritis who came to our attention with large synovial cysts. Ultrasonographic examination and MRI were performed in all cases, showing the real nature of the swelling and the connection to the joint. In all cases, swelling reduced and then disappeared with control of disease activity; in two cases, they reappeared in coincidence with a severe relapse of juvenile idiopathic arthritis. Brachial swellings represent a diagnostic challenge because they can be the clinical expression of a variety of diseases. In children with juvenile idiopathic arthritis who present with a sudden swelling of the upper arm, synovial cysts must be considered in the diagnostic workout, because they are a possible rare manifestation of juvenile idiopathic arthritis

    Localized severe scleroderma: a retrospective study of 26 pediatric patients

    Juvenile localized scleroderma includes different conditions characterized by skin hardening with increased collagen deposition. Although juvenile localized scleroderma is considered a relatively benign disease, lesions may extend through the dermis, subcutaneous tissue, muscles, and the underlying bone, leading to significant functional and cosmetic deformities. Furthermore, extracutaneous manifestations are described. We retrospectively analyzed a cohort of 26 patients with severe Juvenile localized scleroderma with particular attention to clinical features, therapy, and long-term outcome. A subgroup of three patients has been further evaluated with infrared thermography. Our findings were consistent with the current literature for demographic, laboratory, and clinical characteristics at disease onset, but, with our patients, the prevalence of extracutaneous manifestations was higher, thus confirming the potential for severe juvenile localized scleroderma to affect organs other than the skin, without increased risk of development toward systemic sclerosis. Correlation between various treatments and clinical endpoint showed that systemic therapy lead to a better outcome: in particular, methotrexate appeared the most effective drug, capable in halting the progression of the disease and sometimes inducing its regression

    Acquired acral lipodystrophy in a 6-year-old girl

    We report a case of partial lipodystrophy in a 6-year-old girl with normal lipid and glucose metabolism and no family history for similar disorders. The clinical presentation, the laboratory investigations and the natural history in our patient do not match the diagnostic criteria for any of the established lipodystrophy subsets
