Müllerian Cysts of the Posterior Mediastinum: A Case Report and Review of the Literature.

Cysts can be segregated according to their embryonic backgrounds. The cysts that were found in the mediastinum are usually divided into bronchogenic cysts, enteric cysts, esophageal cysts, and nonspecific cysts. We add to the relatively small body of literature that exists on this topic by reporting a case of a Müllerian cyst occurring in the posterior mediastinum of a 60-year-old female, showing diffuse nuclear positivity for estrogen receptor (ER) and PAX-8. We examined and summarized the findings of the unique reported cases in the literature. Lastly, an institutional retrospective review of all posterior mediastinal lesions in the last 38.5 years was performed. This revealed that out of 135 candidates within our own healthcare system, the only case consistent with the diagnosis of a mediastinal Müllerian cyst is the report included herein.

Case Report of a Complex Chest Wall Reconstruction with a Cadaveric Achilles Tendon.

BACKGROUND Chest wall reconstruction is sometimes needed after resection of a thoracic malignancy. Various materials and techniques have been utilized to restore stability and integrity to the chest wall. We report what we believe is the first use of a cadaveric Achilles tendon to restore stability and function to the chest wall of a young woman who underwent chest wall resection and right upper lobectomy for a superior sulcus tumor. CASE REPORT A 46-year-old woman underwent resection of her first through fourth right ribs in addition to her right upper lobe for a squamous cell superior sulcus tumor. Because it was felt her right scapula provided sufficient coverage of her resultant chest wall defect, her chest wall was not reconstructed post-operatively. The patient experienced 2 episodes of scapular prolapse into her thoracic cavity several months after her resection. After the second episode, her right chest wall was successfully reconstructed with a cadaveric Achilles tendon to prevent further episodes of prolapse. CONCLUSIONS We believe this is the first description of chest wall reconstruction with a cadaveric Achilles tendon. The use of a cadaveric Achilles tendon should be considered for reconstruction of the chest wall after complex resection due to its strength characteristics, resistance to subsequent infection, and availability.

Combined video-assisted thoracoscopic lung volume reduction surgery and lobectomy in a high-risk patient.

Nonsmall cell lung cancer often occurs in patients with severe emphysema. Lobectomy in these patients is often contraindicated due to extensive parenchymal destruction and subsequent pulmonary insufficiency. Video-assisted thoracoscopic lobectomy has been described as a less morbid procedure in high-risk patients. Lung volume reduction surgery has been shown to improve pulmonary function in selected patients with emphysema. We describe the successful combination of lobectomy and lung volume reduction surgery (LVRS) with a video-assisted thoracoscopic (VATS) approach in a high-risk patient with Stage I nonsmall cell lung cancer.
