Cryptococcosis is a systemic fungal infection associated with significant morbidity and mortality. It predominantly affects people with immunosuppresion and human immunodeficiency virus infection. Extrapulmonary dissemination is rare in immunocompetent hosts. We present here a case of disseminated cryptococcosis in an immunocompetent patient who presented with an unusually large pulmonary mass and meningitis and successfully managed with medical therapy.
Pulmonary mucormycosis is a life‐threatening invasive fungal infection usually seen in the background of immunosuppression, haematological malignancies, or uncontrolled diabetes. Immunocompetent hosts can also be affected. Isolated endobronchial mucormycosis is rare with only a few cases reported in the literature. Here, we present a case of an endobronchial mass masquerading as a tumour that was later diagnosed as invasive mucormycosis by histopathological examination.
Melioidosis is a Gram‐negative bacterial disease caused by Burkholderia pseudomallei. It has got an increasing prevalence in India, although it is not endemic in the country. Rarely, this disease may pose a diagnostic dilemma, because of its similarities with tuberculosis in clinical, radiological, and pathological features. Mediastinal lymphadenopathy as a presentation is rare in melioidosis. Endobronchial ultrasound (EBUS) could be a useful technique in obtaining samples from necrotic mediastinal lesions. We report three cases of mediastinal melioidosis where EBUS‐guided fine needle aspiration (FNA) aided in early diagnosis.
Spontaneous pneumomediastinum is a benign disorder, but underlying lung diseases and concomitant pneumothorax are likely to complicate the disease course. Exacerbation of post-tubercular obstructive airway disease is a common risk factor for spontaneous pneumomediastinum in a tuberculosis endemic country.
Tracheal tumor is a rare entity. Tracheal tumor may be a primary tracheal tumor or secondary to invasion from a mediastinal tumor (or a lymph node). These tumors are prone to cause critical airway obstruction which may require urgent care. Tuberculosis is one of the common differential diagnoses of mediastinal lymphadenopathy in TB endemic countries, though isolated tuberculous mediastinal lymphadenopathy without a lung involvement is rare. We report an extremely rare case of isolated paratracheal lymphadenitis due to tuberculosis, eroding the trachea and presented a lower tracheal tumor, which recurred again after complete debulking. Finally, the disease required a ‘Y’ stent placement, to stabilize the airway following the second recanalization. We discuss the incidence, differential diagnosis, and the bronchoscopic, interventional aspects of this entity.
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.
