Progressive myalgia as the sole manifestation of cancer-associated myositis: A case report and review of the literature

This case underscores the importance of considering CAM in patients with unexplained symmetrical proximal muscle pain, even in the absence of typical extramuscular symptoms. The detection of myositis-specific autoantibodies is critical for accurate diagnosis. Early identification and treatment of the underlying malignancy can significantly improve prognosis. Future research should focus on elucidating the pathogenesis of CAM, identifying more specific biomarkers, and developing standardized diagnostic and therapeutic guidelines to enhance early diagnosis and treatment outcomes.
