A clinicopathological study of thymic neoplasms: Nine-year experience at a tertiary care hospital in western Maharashtra, India

Abstract

The thymuses are quite rare neoplastic lesions arising in anterior mediastinum seen in the adults. The histological spectrum varied from the encapsulated thymoma to the thymic carcinomas. Further subtyping into various groups on the basis of morphology with immunohistological findings have gained the popularity as depicted by the latest WHO classification of thymomas. A few studies have been done to ascertain the characteristics of thymic neoplasms in Indian population. Methodology: 09 years retrospective analysis of the total 17 thymoma cases reported from year 2011 to 2019 were assessed for histomorphological features with clinical findings, age, sex and staging. Results: The commonest subtypes were of B2 and B1 types with type A, AB and B3 being rare. Mostly the cases were of low grade. Myasthenia Gravis was associated with only 02 thymomas.
