PG - e202202714 LID - 10.5546/aap.2022-02714.eng [doi] AB - Pleuropulmonary synovial sarcoma (PPSS) is a primary malignancy of the lung, uncommon in pediatrics (prevalence: 0.1-0.5%) that predominantly affects adolescents and young adults. Overall survival has been reported to be close to 30% at 5 years. Here we report the case of a previously healthy 12-year-old male patient who presented with cough, chest pain, and dyspnea of sudden onset as initial manifestation of left pneumothorax, which persisted after 4 days and required surgical resection of pulmonary bullous lesion. A histological diagnosis of pleuropulmonary synovial sarcoma was made and confirmed by molecular study, which showed chromosomal translocation between chromosomes X and 18: t(X;18) (p11.2;q11.2) in the surgical specimen removed. In patients with persistent or recurrent pneumothorax, it is important to rule out secondary causes, including pleuropulmonary synovial sarcoma. Such poor prognosis determines the need for early diagnosis and aggressive treatment. CI - Sociedad Argentina de Pediatria.
