Özet

Primary thymic seminoma is an exceedingly rare tumour. There are few case reports about mediastinal thymic seminoma accompanied by secondary changes. We report a case of a 29-year male admitted to our hospital because of chest pain and dyspnea for 8 months. Computed tomography of the thorax revealed hypodense, solid masses showing calcification and cystic degeneration in the anterior mediastinum. Histopathological examination of the resected specimen revealed a diagnosis of thymic seminoma with regressive and reactive changes. The present case was unique in its presentation as a primary seminoma showing combination of cystic degeneration, follicular hyperplasia, fibrosis, calcification and granulomatous reaction in one case. High level of suspicion is necessary to identify seminomas in a thymic lesion accompanied by secondary changes. Excluding the possibility of metastasis from testicular seminoma is very important before making this diagnosis. Key Words: Thymus, Seminoma, Granuloma, Calcification, Cyst.
