Recurrent pulmonary synovial sarcoma effectively treated with amrubicin: A case report

Endobronchial ultrasound-guided transbronchial needle aspiration in diagnosing mediastinal lymphadenopathy: Experience from a tertiary care centre

Background

The evaluation of mediastinal lymphadenopathy and masses poses a diagnostic challenge because of a myriad of possible etiologic causes; their proximity to numerous vital structures and the difficulty of access for biopsy. Computed tomography is an excellent modality for the initial evaluation of mediastinal lymph nodes (LNs). Tissue diagnosis is of paramount importance to confirm the diagnosis of mediastinal lymphadenopathy. Of various modalities including CT-guided biopsy, mediastinoscopy is considered a gold standard for tissue acquisition, but it is associated with considerable morbidity. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive method of sampling of mediastinal LNs and its role has been established in malignant cause of LN enlargement. However, its role in diagnosing benign diseases has not been studied much.

Methods

In a cross-sectional observational study, we performed EBUS-TBNA of 116 patients, and the sample was evaluated by various pathological modalities.

Results

Most common LN sampled was subcarinal (68%). MTB gene Xpert was positive in 45 cases, and resistance was detected in 3 cases. Most common diagnosis was tuberculous lymphadenitis (67.9%). Only five of our patients had post-operative bronchospasm, while four had peri-operative hypoxia, which was managed with oxygen therapy.

Conclusion

EBUS-TBNA is an excellent modality for sampling mediastinal LNs, which is very safe and can be done on an OPD basis.

Diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in solitary mediastinal, hilar lymphadenectasis, or peribronchial lesions: Six cases reports and review of literature

BACKGROUND

Patients with isolated mediastinal or hilar lymphadenopathy, or peribronchial lesions, are common presentation to clinicians. Due to the difficulty in tissue sampling, the pathological diagnosis is not so easy. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established, highly effective, minimally invasive technique for sampling. The current study was conducted to investigate the value of EBUS-TBNA in patients of solitary mediastinal, hilar lymphadenectasis, or peribronchial lesions.

METHODS

Six patients with different pathological results diagnosed via EBUS-TBNA were retrospectively analyzed in this study.

RESULTS

All 6 patients of solitary mediastinal, hilar lymphadenectasis, or peribronchial lesions underwent conventional flexible bronchoscopy before EBUS-TBNA, but only EBUS-TBNA was helpful for the finally definite diagnosis. No complication was observed.

CONCLUSION

EBUS-TBNA is a safe and highly effective diagnostic procedure for both benign and malignant diseases, especially for patients with solitary mediastinal, hilar lymphadenectasis, or peribronchial lesions.

Multimodality management of primary diaphragmatic synovial sarcoma: First report

Synovial cell sarcoma is an extremely rare tumor of mesenchymal origin. It commonly affects the soft tissues of the extremities but could possibly origin from the head and neck, heart, lung, pleura, mediastinum, esophagus, abdominal wall and the mesentery, and retroperitoneum. Primary synovial sarcoma of pleura, mediastinum, and lung have been reported. Primary synovial sarcoma of the diaphragm has not been reported to the best of our knowledge. We report a case of primary synovial cell sarcoma of the diaphragm presenting as a recurrent pleural effusion and pain in the left hypochondrium managed with multimodality approach.
