Un tumor intrapulmonar “out of the box”

Resumen

Primary intrapulmonary thymomas (PIT) are very rare tumors of unclear pathogenesis. We report a case of a 60-years-old woman who present with an accidental finding of a mass on her chest. Histology analysis shown to be primary intrapulmonary thymoma and she underwent surgical resection, remaining currently asymptomatic and without evidence of recurrence or metastasis. Since its rarity, reporting these cases is essential to better understand its clinical course and management.
