RESUMO
Introduction: Distance metastasis of cutaneous squamous cell carcinoma (cSCC) to pleural is rarely reported, and meets difficulties in diagnosing due to quality of pleural biopsy sample. This case presented a novel technique by using cryobiopsy to obtain adequate sample and was first conducted in our hospital. Case presentation: A 62-years-old man admitted to hospital with dyspnoea due to massive right pleural effusion. Lung multi-sliced computed tomography showed right lung pleural effusion with compression atelectasis as well as collapse of medial lobe and upper lobe, multiple solitary nodules on mediastinal, costal antero-posterior and right diaphragm pleural part. Medical thoracoscopy was performed to obtain pleural samples by using cryobiopsy and forceps biopsy. Pathological analysis with Immunohistochemistry (IHC) revealed metastatic squamous cell carcinoma. Discussion: Recurrence rate of cSCC remains high even after treatment, with worse prognosis. Distant metastasis to pleural is rarely reported. Clinical approach for malignant pleural effusion by using medical thoracoscopy has 80% sensitivity with minimal complication. Pleural cryobiopsy is a novel technique used for obtaining sample from pleural biopsy with significant larger size of the specimen, less crush artefacts, fragmented and better tissue integrity, although the diagnostic yield and bleeding severity between cryobiopsy and conventional forceps biopsy are not significant. Conclusion: Medical thoracoscopy with cryobiopsy should be considered as a preferrable diagnostic tool for obtaining better sample specimen, especially for pleural metastatic.
RESUMO
OBJECTIVE: To define the molecular epidemiology of respiratory viral infections in adult patients. METHODS: Nasal and throat swabs were collected from all adult patients with influenza-like illness (ILI), acute respiratory infection (ARI), or severe ARI (SARI) admitted to a tertiary hospital in Surakarta, Indonesia, between March 2010 and April 2011 and analyzed for 19 respiratory viruses and for torque teno virus (TTV) and human gyrovirus (HGyV). RESULTS: Respiratory viruses were detected in 61.3% of the subjects, most of whom had ARI (90.8%, OR = 11.39), were hospitalized (96.9%, OR = 22.31), had asthma exacerbation (90.9%, OR = 8.67), and/or had pneumonia (80%, OR = 4.0). Human rhinovirus (HRV) A43 predominated. Influenza A H3N2, human metapneumovirus (HMPV) subtypes A1 and A2, the influenza B virus, human adenovirus B, and human coronavirus OC43 were also detected. All respiratory viruses were detected in the transition month between the rainy and dry seasons. No mixed respiratory virus infection was found. Coinfections of the influenza A H3N2 virus with TTV, HMPV with TTV, HRV with TTV, and human parainfluenza virus-3 with TTV were found in 4.7, 2.8, 19.8, and 0.9% of the samples, respectively. CONCLUSIONS: This study highlights the need to perform routine detection of respiratory viruses in adults hospitalized with ARI, asthma exacerbation, and/or pneumonia.
