We report a case of a 52-year-old patient who had undergone a bladder resection and an ileal conduit for a transitional cell carcinoma. He then presented with a short history of hemoptysis 3 months later. Rigid bronchoscopy was performed revealing an endobronchial lesion, which was removed via laser and debulking method without complications. Histopathologic examination confirmed it to be a benign endobronchial glomus tumor. On the basis of our literature search, this is the 34th reported case of glomus tumor arising from the respiratory tract, seventh reported case of an endobronchial glomus tumor treated bronchoscopically, and the first possibly coincidental finding in relation to a patient with primary transitional bladder cell carcinoma.

Clinical experience with extensively Drug Resistant tuberculosis (XDR-TB) has not been reported in Malaysia before. We describe the clinical characteristics, risk factors, progress and therapeutic regimen for a healthcare worker with XDR-TB, who had failed therapy for multidrug resistant TB (MDR TB) in our institution. This case illustrates the risk of TB among healthcare workers in high TB-burden settings, the importance of obtaining upfront culture and susceptibility results in all new TB cases, the problem of acquired drug resistance developing during MDR-TB treatment, the challenges associated with XDR-TB treatment regimens, the value of surgical resection in refractory cases, and the major quality of life impact this disease can have on young, economically productive individuals.

In clinical practice, chylothorax is usually suspected in any patient with milky pleural fluid. However, contrary to popular belief, milky appearance of pleural fluid is seen in less than half of patients with chylothorax. A high index of suspicion for chylothorax is therefore needed in any turbid, bloody, or serosanguinous effusions of unclear aetiology. In this case series, we present three patients with biochemically proven chylothorax: each with a different presentation, pleural fluid appearance, underlying cause, management strategy and clinical outcome. The first patient developed 'milky' chylothorax secondary to lymphoma while the second patient's 'yellow' chylothorax is related to pleural tuberculosis. The final patient suffered from 'pink' chylothorax in the setting of systemic amyloidosis. In each of the cases, prompt diagnosis of chylothorax followed by efforts to elucidate the underlying cause are crucial steps to guide subsequent management with the main aim to ensure a better clinical outcome.

Fulltext Early experience of endobronchial ultrasound-guided transbronchial nodal cryobiopsy: a case series from Sabah, Malaysia

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established minimally invasive method for the diagnosis of benign and malignant conditions. Continuous efforts are underway to improve the material adequacy of EBUS-TBNA, including the introduction of a new technique called EBUS-guided transbronchial nodal cryobiopsy (EBUS-TBNC). This method allows for the retrieval of larger and well-preserved histologic samples from the mediastinum. We present a case series of four patients who underwent combined EBUS-TBNA and EBUS-TBNC procedures in our centre. All procedures were performed under general anaesthesia using a convex probe EBUS scope (Pentax EB-1970UK). Two patients were diagnosed with malignancy and two with benign disorders (silicosis and tuberculosis). In the malignant cases, both EBUS-TBNA/cell block and cryobiopsy provided a diagnosis but cryobiopsy yielded more material for ancillary tests in one patient. However, in the benign cases, there was discordance between EBUS-TBNA/cell block and cryobiopsy. Only cryobiopsy detected granuloma in the patient with TB (tuberculosis), and in the patient with silicosis, TBNC provided a better overall histological evaluation, leading to a definitive diagnosis. No complications were observed. This case series supports the potential diagnostic value of combining EBUS-TBNA and EBUS-TBNC, particularly in benign mediastinal lesions (granulomatous diseases), and in cases requiring additional molecular tests in cancer diagnosis.

Pleural fluid residue as a diagnostic tool for cytology-negative malignant pleural effusion: A proof-of-concept study

BACKGROUND: Pleural fluid residue, or macroscopic tissue, circulating freely in the pleural fluid obtained through direct filtration, may carry diagnostic histopathological information. We aimed to determine the histopathological concordance of pleural fluid residue in diagnosing TPE and MPE, compared with conventional pleural biopsy. This was a prospective cohort study of consecutive inpatients with cytology-negative exudative effusion who underwent pleuroscopy and had their initial suctioned pleural fluid filtered for residue samples. Pleural fluid residue demonstrated malignant cells in four out of seven cases of pleural biopsy-confirmed malignancy. Pleural fluid residue has comparable cytomorphology but reduced cellularity compared with pleural biopsy. No tuberculous histological features were present in the pleural fluid residue samples. In this preliminary study pleural fluid residue provided histopathological information for malignant pleural effusion, but no incremental diagnostic information for tuberculous effusion. However larger and more definitive studies are required to clarify these findings, and to explore the utility and suitability of pleural fluid residue for mutational analysis.

WHAT THE STUDY ADDS: This study demonstrates the potential of pleural fluid residue as a non-invasive diagnostic method for confirming malignancy in cytology-negative exudative effusion.

WHAT ARE THE IMPLICATIONS OF THE FINDINGS: In resource-limited settings or patients contraindicated for pleural biopsy, pleural fluid residue may provide a viable diagnostic alternative; however, this observation needs further validation.
