Stiff person syndrome (SPS) is a neurologic disorder, some cases of which are associated with malignant disease. Here, we report a case of thymoma-associated SPS that was successfully treated with surgical resection. A 57-year-old man with progressive muscle stiffness and weakness was diagnosed with thymoma-related SPS.

Background: Research shows that thymoma-associated myasthenia gravis (MG) patients exhibit immunological imbalances, including anomalies in immune indicators. The link between these abnormalities and thymectomy outcomes is not well-understood. This study aims to assess the impact of immunological markers like T helper (Th)17 cells, regulatory T (Treg) cells, CD4 T, CD8 T cells, immunoglobulin (Ig)G, IgA, IgM, IgE, C-reactive protein (CRP), complement C3, and complement C4 on MG prognosis post-thymectomy.

Thymomas are rare tumors originating from thymic tissue, often associated with various paraneoplastic syndromes that can pose significant clinical management challenges. Myasthenia gravis, one of the most common paraneoplastic syndromes linked to thymomas, is characterized by autoantibodies targeting the neuromuscular junction, leading to muscle weakness exacerbated by repetitive use. Good's syndrome, an adult-onset immunodeficiency associated with thymomas, results in hypogammaglobulinemia and susceptibility to opportunistic infections, which can be life-threatening.

Patients with thymoma (THYM)-associated myasthenia gravis (MG) typically have a poor prognosis and recurring illness. This study aimed to discover important biomarkers associated with immune cell infiltration and THYM-associated MG (THYM-MG) development. Gene expression microarray data were downloaded from The Cancer Genome Atlas website (TCGA) and Gene Expression Omnibus (GEO).

Myasthenia gravis (MG) stands as a prototypical antibody-mediated autoimmune disease: it is dependent on T cells and characterized by the presence of autoantibodies targeting proteins located on the postsynaptic surface of skeletal muscle, known as the neuromuscular junction. Patients with MG exhibit a spectrum of weakness, ranging from limited ocular muscle involvement to life-threatening respiratory failure. Recent decades have witnessed substantial progress in understanding the underlying pathophysiology, leading to the delineation of distinct subcategories within MG, including MG linked to AChR or MuSK antibodies as well as age-based distinction, thymoma-associated, and immune checkpoint inhibitor-induced MG.
