Mediastinal Thymic Cyst in Adults: A Rare Case Report

Thymic cysts are rare, benign lesions located in the cervico-thoracic region, often incidentally discovered. The only curative treatment is complete surgical excision, which eliminates symptoms, prevents complications, and provides a definitive diagnosis through histopathological examination, typically revealing the presence of Hassall's corpuscles. Minimally invasive approaches are preferable. We present the case of a 40-year-old patient with an anterior mediastinal cystic mass that underwent successful complete surgical resection. The histopathological examination confirmed a diagnosis of benign unilocular thymic cyst, resulting in favorable clinical and radiological outcomes.
