Introduction: Mature cystic mediastinal teratoma is a primary germ cell neoplasm with benign features, composed of fully differentiated tissues derived from more than one of the three embryonic germ cell layers, occurring mainly in adolescents and young adults. They occur most frequently in the anterior compartment, secondarily at the level of the thymus and rarely in the posterior compartment. Clinical case: We present the case of a 13-year-old adolescent patient with an apparent mediastinal tumor, which caused moderate chest pain, dyspnea on moderate exertion accompanied by asthenia and progressive weight loss. Treatment: Total resection of the anterior mediastinal tumor is performed, which confirms the histopathological diagnosis of solid cystic mature tridermal cystic teratoma of the mediastinum, with negative lymph nodes for malignancy. Conclusion: Mature cystic teratoma is the most frequent pathology of mediastinal tumors, of benign characteristics, with non-specific symptomatology. Surgical resolution remains the gold standard in terms of treatment, with low recurrence rates after complete surgical resection and with a good short, medium and long term prognosis.
