Intercostal lung herniation secondary to thoracotomy: a case report.

Intercostal lung herniation is defined as a protrusion of the lung parenchyma through a defect in the intercostal muscles between adjacent ribs. The authors report a case of intercostal pulmonary hernia in a 45-year-old male patient, with smoking habit (30 packs-year), presented to the emergency department with dyspnea. He had the history of pulmonary emphysema complicated with a total right pneumothorax in 2015 treated by mini-thoracotomy with bullectomy and pleural abrasion. In 2019, he was admitted to hospital for left chest pain. The computed tomography (CT) scan of the chest revealed a bilateral emphysema with intercostal lung hernia through the fourth intercostal space the patient underwent, a left thoracotomy with repair of the intercostal muscle defect. He was discharged from hospital free of complications.

Second lung malignancy and Richter syndrome in chronic lymphocytic leukemia: case report and literature review.

BACKGROUND: Chronic lymphocytic leukemia (CLL) is the most frequent lymphoproliferative disease. Transformation into Richter disease and occurrence of second malignancies involving the lungs are rare complications. The hallmarks of any thoracic involvement are still unknown. CASE PRESENTATION: We report a case of a 56-year-old male patient, with history of tobacco smoking, who presented with recurrent hemoptysis, fatigue and weight loss. Physical examination was normal except a slightly enlarged supraclavicular lymph node. Chest x-ray revealed a mediastinal widening due to enlarged paratracheal nodes and a left parahilar infiltrate. Blood tests showed a hyperlymphocytosis and a biological inflammatory syndrome. CT scan showed bilateral mediastinal and axillary lymphadenopathy, as well as left supraclavicular lymphadenopathy, with a left upper lobe alveolar attenuation and a solitary contralateral pulmonary nodule. Examination of Virchow's node and bone marrow biopsies confirmed metastasis of a pulmonary adenocarcinoma, as well as chronic lymphocytic leukemia with Richter's transformation. The clinical course was unfavorable since the first days of therapy as the patient passed away in a matter of a few days. CONCLUSIONS: Steady surveillance of CLL patients and systematic screening for second solid tumors, particularly lung cancer, and Richter's transformation seem to be relevant more than ever. Early diagnosis might help us understand the pathways leading to these complications and adapt therapy.
