A case of linear scleroderma and myasthenia gravis

Area of Science:

• Rheumatology and Neurology
• Autoimmune Diseases

Background:

• Myasthenia gravis is a neuromuscular autoimmune disorder.
• Scleroderma encompasses autoimmune conditions affecting connective tissues.
• Co-occurrence of myasthenia gravis and scleroderma is exceptionally rare.

Observation:

• A 28-year-old woman with a history of myasthenia gravis developed linear scleroderma seven years later.
• This represents a unique case, as previously reported associations involved systemic scleroderma, not localized forms.
• The patient's history suggests a potential link between these autoimmune conditions.

Findings:

• The direct association between myasthenia gravis and scleroderma is infrequently documented.
• Only five previous cases reported this association, all with systemic scleroderma.
• This case introduces linear scleroderma in conjunction with myasthenia gravis.

Implications:

• Autoimmunity is a suspected common pathogenic mechanism for both myasthenia gravis and scleroderma.
• The findings suggest a possible autoimmune predisposition underlying the co-occurrence of these conditions.
• Further research into shared autoimmune pathways may elucidate the relationship between myasthenia gravis and scleroderma.
