Associated conditions

Thymomas may occur in association with a variety of autoimmune and haematological phenomena including: (1,2)

• myasthenia gravis - the most common association but less often associated with more aggressive thymomas (1)
  
• haematological cytopenias e.g. aplastic anaemia
  
• hypogammaglobulinaemia
  
• collagen vascular diseases e.g. systemic lupus erythematous
  
• non-thymic malignancies
