Coccidioidomycosis is endemic in the south-western USA. Two cases of infection in travellers returning to Hong Kong are described. A previously healthy patient who had travelled to an endemic area for a short time was successfully treated with fluconazole. A second patient with comorbidities and more prolonged exposure had disseminated and eventually fatal disease, despite prolonged administration of anti-fungal agents. Although coccidioidomycosis is a rare disease in Hong Kong, it should always be considered when there is a relevant travel history. Even a short period of travel to an endemic area should alert clinicians to this possibility when managing patients with severe pneumonia, especially those with multi-organ involvement. On the other hand, in patients with comorbidities, even aggressive and prolonged anti-fungal therapy may not guarantee a successful outcome.
Pulmonary artery sarcoma is a rare disease with poor prognosis that has not been reported in Hong Kong. Its clinical and radiological presentation frequently mimics pulmonary embolism. Diagnosis is usually delayed until surgery, which is the treatment option that provides the best survival. Endobronchial ultrasound-guided transbronchial needle aspiration is an effective non-surgical technique for lymph node staging of lung cancer and diagnosis of mediastinal lesions via bronchoscopy. Here we discuss a case of pulmonary artery sarcoma diagnosed by this method, the second one in the literature, which serves to illustrate its potential use for early and minimally invasive diagnosis of the condition. Although such aspiration is a safe procedure, tissue sampling of extravascular extensions is advisable wherever possible.
Our survival results are consistent with the recent international literature and indicate that a proportion of patients with locally advanced NSCLC can enjoy prolonged survival following treatment with concurrent chemoradiation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
