Pdf Summary

The document details the minimally invasive thoracoscopic resection of a micronodular thymoma with lymphoid stroma (MNT) using a subxiphoid single-incision approach. MNT is a rare thymoma variant, and few such surgical cases are reported. The study is from the Thoracic Surgery Department at the Shenzhen Third People's Hospital, China. It outlines representative cases involving patients initially diagnosed with thymic cysts preoperatively, which were revised to MNT post-surgery. The surgery involved excising anterior mediastinal tumors with the aid of sternal hooks to improve visualization.<br /><br />The patients underwent a subxiphoid single-incision, a novel technique for such resections, and all had uneventful recoveries and were discharged without complications. Over a 12-month follow-up, none showed signs of disease recurrence, indicating the procedure's potential effectiveness. <br /><br />The text emphasizes the importance of recognizing the unique pathological features of MNT. Though often misdiagnosed as thymic cysts, it's crucial for medical professionals to consider MNT when cystic lesions in the thymus appear, ensuring patients receive accurate treatment. This single-port thoracoscopy technique offers an effective option for thymic tumor removal.<br /><br />Figures included depict CT scans of the mediastinal lesion, the surgical incision location, and resected thymoma tissues. Microscopic examination highlights tumor nodules of spindle epithelial cells in a lymphoid-rich stroma, with certain cells stained CK19 and others, CD20, illustrating the tumor's complex structure. This approach demonstrates promising outcomes in treating a rare thymic tumor variant via the subxiphoid method.
