BACKGROUND: Head and neck @entity1823 are rare @entity5 and can arise as a part of @entity74 . Their association with thymic @entity5 is not well known. CASE DESCRIPTION: This report describes a female @entity1 who presented with right sided neck @entity1823 . The histology of the @entity5 was consistent with paraganlioma. Few years later her MRI scan of the chest revealed presence of an anterior mediastinal mass that corresponded to the location of the thymus. Review of her previous scans showed that the mass was present all along and had gradually increased in size. @entity1 developed symptoms including @entity1295 , dyspnoea, @entity625 , @entity2407 and @entity5406 . She had sternotomy and excision of mediastinal mass. The histology was consistent with @entity704 (WHO type B2) and she had radiotherapy. After treatment her constitutional symptoms improved. Her @entity1823 susceptibility genes are negative. DISCUSSION AND EVALUATION: To our knowledge this is only the second case report in the literature of coexistence of @entity5 and @entity704 . The first case reported was bilateral @entity5 , @entity259 and @entity704 . This case also highlights the importance of long term surveillance, multidisciplinary management and being aware of associated pathologies in @entity1 with @entity1823 .
