Pediatric Thymoma with a Difference: Report of a Case and Review of Literature

Thymoma represents 1% of all mediastinal tumors in children. Less than 50 cases of pediatric thymoma are reported in the literature. Thymomas are considered to be highly aggressive in pediatric patients, especially when age is 10 years. Paraneoplastic syndromes, of which around 70% are myasthenia gravis, correlate with poor prognosis. In this article, we report a case of a thymoma in an 8‑year‑old boy, who had favorable histopathology (Masaoka stage I, WHO type B2), despite the presence of young age and necrosis along with absence of myasthenia gravis. We have also reviewed the available literature on pediatric thymoma.
