Thymoma with Myasthenia Gravis in Pregnancy: A Case Report

Abstract

Thymoma is the commonest mediastinal tumour but a rare type of thymic tumour of unknown aetiology. The overall incidence of thymoma is 0.13 per 100,000 persons per year which is even rarer in pregnancy. Until this date, the specific link between thymoma and pregnancy has not been identified. Presentations are also variables and includes chest pain, respiratory insufficiency, superior vena cava syndrome or non-specific symptoms like fever and weight loss. An autoimmune paraneoplastic disease which is often linked with thymoma includes myasthenia gravis (MG), hypogammaglobinaemia, aplastic anaemia and systemic lupus erythematosus (SLE). Here we describe a case of thymoma in pregnancy who had successfully delivered and underwent surgical removal postpartum.
