Malign plevral mezotelyoma (MPM), genellikle asbest maruziyeti ile oluşan, lokal, invaziv karakterli bir tümördür. MPM çoğunlukla asemptomatik seyretmesine rağmen tümörün boyutu ve komplikasyonları nedeniyle nefes darlığı, göğüs ağrısı gibi semptomlar verebilmektedir. Genellikle plevral efüzyon ile tespit edilen MPM, nadiren spontan pnömotoraks sonrası tanı almaktadır. MPM'nin tedavisinde tümör cerrahi olarak rezeke edilebilecekse plevral dekortikasyon, plörektomi veya ekstraplevral pnömonektomi gibi cerrahi teknikler bulunmaktadır. Cerrahiye uygun olmayan hastalar içinse kemoterapi uygun bir seçenektir. Yazımızda 69 yaşında bilinen bir hastalığı olmayan spontan pnömotoraks ile kliniğimize başvuran hastada total plörektomi materyalinden MPM tanısı alan olgu sunulacaktır. Bu çalışmada, malign mezotelyomanın nadiren de olsa pnömotoraks tablosuyla görülebileceği gösterilmiştir.

Background: The aim of this study was to investigate the prevalence of novel coronavirus disease 2019 (COVID-19) in patients hospitalized with primary spontaneous pneumothorax and to evaluate its possible effects on the clinical course, treatment, and the prognosis. Methods: Between April 2020 and January 2021, a total of 86 patients (78 males, 8 females; mean age: 27±5 years; range, 16 to 40 years) who had no underlying lung disease and were diagnosed with the first episode of spontaneous pneumothorax were retrospectively analyzed. At the same time of diagnosis, all patients were screened for COVID-19 via polymerase chain reaction test of nasopharyngeal swabs. According to the test results, the patients were divided into two groups as COVID-19(+) and COVID-19(–). The duration of air leak, hospital stay, recurrence rates and treatment modalities, and mortality rates of the two groups were compared. Results: Following a pneumothorax diagnosis, 18 (21%) patients were diagnosed with COVID-19. In COVID-19(+) patients, the mean air leak and lung expansion duration were significantly longer (p<0.0001 for both). In these patients, the mean length of hospital stay was also significantly longer (p<0.0001). During the median follow-up of six months, no mortality was observed and the recurrence rate was similar between the two groups (p=0.998). Conclusion: Our study results suggest that COVID-19 negatively affects the recovery time in patients with spontaneous pneumothorax.

Surgical procedure is still used as the first choice in the treatment of pulmonary hydatid cysts. Video-assisted thoracoscopic surgery has started to be performed as a minimally invasive surgical option in recent years for lung hydatid cyst; however, few cases have been reported in the literature, especially in children. Thoracoscopic surgery experience is limited in pulmonary hydatid cyst for both adults and children. We present a pediatric case of giant lung hydatid cyst, in which we performed partial capitonnage with video-assisted thoracoscopic surgery and fibrin glue.
