Single-Center Experience of Management of Mediastinal Cyst-A Case Series.

Background Mediastinal cysts are benign lesions that may be seen in adulthood as well as in childhood. Mostly congenital lesions constitute 20 to 32% of lesions located in the mediastinum. The main cystic masses are congenital benign cysts (bronchogenic, esophageal replications, neuroenteric, pericardial and thymic cysts), meningocele, mature cystic teratoma, and lymphangioma. In this study, we aimed to analyze the mediastinal cysts operated in our clinic according to the histopathological type, surgical type, morbidity rates and to contribute to the literature on these rare lesions. Methods The records of patients with mediastinal cysts who were operated in Gazi University Faculty of Medicine Department of Thoracic Surgery, between January 2013 and June 2021, were reviewed retrospectively. Results A total of 32 patients were included the study. Thirteen (40.6%) of the patients were male and 19 (59.4%) were female. The mean age was 45 (range: 12-71). The most common symptom in patients was chest pain with 12 patients. Histopathologically, the most common subtype was thymic cyst. Video-assisted thoracic surgery was applied in 19 patients (59.3%), thoracotomy in 8 patients (25%), and sternotomy in 5 patients (15.63%). There was no mortality. Conclusion In patients with mediastinal cysts, the prognosis after complete excision is excellent and rates of morbidity and mortality associated with surgery are low.

Rare cause of pleural nodularity: Splenosis.

Splenosis is a rare condition described as ectopic splenic tissue implantation generally after a splenic rupture. A 35-year-old male patient who had a history of splenectomy operation due to gunshot wound seven years ago was referred to our hospital with complaints, including exhaustion, sweating and shortness of breath. Thoracic computed tomography of the patient showed nodular pleural thickenings at the level of the left lower lobe, which proved to be unrelated with the presenting symptoms. The patient underwent a minithoracotomy for diagnosis and treatment. During the intraoperative observation, dark-colored, soft, multiple nodular lesions with a biggest size of 2 cm inside the visceral pleura over an area of 5 x 10 cm in dimension were observed. Also, a few tiny nodules in the lung parenchyma approximately 1-cm deep to the pleural nodules were palpated. The lesions were excised. The histopathological examination of the specimen showed splenic tissue in the lung parenchyma and pleura, so the lesions were accepted as splenosis. Pleuropulmonary splenosis, which develops generally after simultaneous rupture of the diaphragma and spleen, is a very rare condition. Most of the patients are asymptomatic and the lesions are detected accidentally. If the diagnosis can be made preoperatively, surgical excision is not needed.

Localized fibrous tumors of the pleura: clinical and surgical evaluation.

BACKGROUND: Localized fibrous tumors of the pleura, which are considered to originate from submesothelial connective tissue, are rare. The purpose of this study was to investigate the clinical features of these tumors and to determine the optimal treatment and follow-up. METHODS: The records of 10 consecutive patients with localized fibrous tumors of the pleura operated on at the Ataturk Center for Chest Diseases and Thoracic Surgery between 1995 and 2001 were retrospectively reviewed. Diagnostic procedures, clinical courses, and outcomes of these patients were studied. Total excision through a thoracotomy was performed in all of the patients. Pneumonectomy was required in 1 patient because of a giant intraparenchymal localized fibrous tumor of the pleura. Additional partial chest wall resections were done in 2 patients. RESULTS: The size of excised tumors ranged from 10 x 8 x 4 cm to 30 x 25 x 20 cm. Malignant transformation was seen in 1 patient 22 months after resection of a benign tumor. Four cases were pathologically considered to be malignant. All patients except 1 are alive (follow-up 16 to 57 months after resection). CONCLUSIONS: Although localized fibrous tumors of the pleura are considered histologically benign tumors, because of the risk of recurrence and malignant transformation, complete surgical resection is indicated and long-term follow-up is recommended in all patients.
