Utilization and Outcomes of Observation for Spontaneous Pneumothorax at an Integrated Health System.

Introduction: Though limited, recent evidence supports observation rather than intervention for spontaneous pneumothorax management. We sought to compare the utilization and outcomes between observation and intervention for patients with primary and secondary spontaneous pneumothoraces.

Methods: A retrospective cohort study of all adults presenting to Kaiser Permanente Northern California emergency rooms with spontaneous pneumothorax from 2016 to 2020 was performed.

Invasive type B2 thymoma associated with myasthenia gravis, resection with superior vena cava reconstruction.

After being diagnosed with myasthenia gravis, a 55-year-old male was referred for treatment of an invasive thymoma. Preoperative imaging revealed a thymoma adjacent to the superior vena cava (SVC) with possible invasion of the left innominate vein. After multidisciplinary discussion, he underwent upfront en bloc resection of the tumor with SVC resection and reconstruction.

Large mediastinal germ cell tumor with disease progression during systemic therapy.

A 29-year-old male developed acute onset severe shortness of breath and fevers and was found to have a 17 cm anterior mediastinal mass with immature teratoma and possible mixed germ cell tumor on biopsy. He remained hospitalized during neoadjuvant cisplatin-based chemotherapy due to compressive symptoms from his mass and neutropenic fevers. Despite 3 cycles of therapy, his tumor mildly increased in size.

Thymoma associated with severe pancytopenia and Good's syndrome: case report.

We report a rare case of thymoma associated with pancytopenia and Good's syndrome. The patient was a previously healthy 60-year-old female who presented to the emergency department with a severe headache. Her initial work up was significant for a parenchymal hemorrhage and severe pancytopenia.
