摘要
A 52-year-old Chinese woman was diagnosed with transcription intermediary factor 1(TIF1)gamma dermatomyositis in November 2022,with manifestations of myositis,polyarthralgia,and low-grade fever.She had cutaneous manifestations of Gottron's sign,V-neck sign,shawl sign,and flagellate erythema(Figure 1A).No interstitial lung disease was detected by high-resolution computed tomography.Comprehensive malignancy screenings,encompassing pap smear and mammogram,endoscopic examination,and computed tomography scans of the thorax,abdomen,and pelvis,were performed.They returned negative,apart from a lobulated nodule with biopsy confirmed as sclerosing pneumocytoma at the left lower lobe(Figure 1C).The therapeutic regimen,consisting of high-dose steroids and mycophenolate mofetil,effectively ameliorated the patient's myositis and rash(Figure 1B).
