Here, we report a case of SVV with pauci-immune glomerulonephritis accompanied by an EBV-positive polymorphic B-cell LPD, not otherwise specified. The intricate distinction between EBV-positive B-cell LPD and SVV was difficult, as both diseases demonstrated similar clinical presentations. Lymph node and kidney biopsies facilitated the accurate diagnosis of these two conditions. The administration of high-dose prednisolone, combined with rituximab, proved efficacious, with no instances of relapse over the subsequent 2-year period. This case indicates an association between EBV-positive B-cell LPD and SVV. The diligent execution of biopsies is a crucial diagnostic and interpretive strategy, generating precise comprehension of this condition and guiding its appropriate therapeutic management.","PeriodicalId":94146,"journal":{"name":"Modern rheumatology case reports","volume":" ","pages":"117-121"},"PeriodicalIF":0.9,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141161335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several autoantibodies have been found specifically in patients with polymyositis/DM, including CADM patients.

SAPHO syndrome is considered on the same spectrum as chronic nonbacterial osteomyelitis/chronic recurrent multifocal osteomyelitis, the former often being the nomenclature in adults and the latter in children. The diagnosis is made on patterns of clinical manifestations and is a diagnosis of exclusion. While skin and bone manifestations are commonly described with SAPHO syndrome, pleural involvement is rare, and few cases have been described in the literature, especially in paediatric patients. Herein we present a 14-year-old female with a past medical history of hidradenitis supprtiva, eczema, psoriasis, and a prior episode of culture-negative osteomyelitis who presented to the emergency room with chief complaints of right-sided pain with inspiration and back pain. Exam revealed palmoplantar pustulosis, hidradenitis supprativa, psoriasis, and tenderness of vertebrae. Imaging showed a right-sided pleural effusion and multiple sites of osteitis. Laboratory evaluation revealed elevated inflammatory markers, an exudative pleural effusion with neutrophilic predominance, and no evidence of malignancy, infection, or immunodeficiency. The patient was diagnosed with SAPHO syndrome and treated with naproxen, methotrexate, and golimumab with significant improvement including resolution of the pleural effusion. Paediatric SAPHO syndrome is a rare disease that classically causes osteitis and skin manifestations. This case highlights that pleural effusion can be a rare manifestation of paediatric SAPHO syndrome. Patients with suspected SAPHO syndrome with respiratory symptoms should be evaluated for pleural effusion.","PeriodicalId":94146,"journal":{"name":"Modern rheumatology case reports","volume":" ","pages":"168-173"},"PeriodicalIF":0.9,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although cancer complications in MDA5-DM are less frequently reported compared to other forms of DM, they do occur. For MDA5-DM patients with cancer, particularly in paraneoplastic settings, the primary treatment strategy often targets the malignancy first. However, surgery, chemotherapy, and radiotherapy carry significant risks of exacerbating ILD, especially in patients with respiratory failure. Despite improved prognosis with initial immunosuppressive combination therapy, some cases of MDA5-DM with RP-ILD remain refractory to treatment. Recent studies have shown the potential benefit of Janus kinase (JAK) inhibitors for refractory cases, though their impact on cancer progression remains a concern. We report a 48-year-old woman with MDA5-DM, RP-ILD, and bilateral breast cancer. Due to her respiratory condition, radical surgery and chemotherapy were initially not possible. Endocrine therapy and immunosuppressive therapy were administered, but the disease remained refractory. Tofacitinib, combined with plasma exchange, improved her ILD, allowing for bilateral mastectomy. One year later, MDA5 antibody titers became negative, and glucocorticoids were discontinued after two years. Three years later, neither MDA5-DM nor breast cancer has recurred. This is the first report of MDA5-DM complicated by breast cancer, and the first use of JAK inhibitors in such a case. Effective treatment requires close collaboration with oncologists to balance the risks and benefits of therapy in cases of MDA5-DM with RP-ILD and cancer.","PeriodicalId":94146,"journal":{"name":"Modern rheumatology case reports","volume":" ","pages":"93-99"},"PeriodicalIF":0.9,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142335402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
