Rituximab Therapy in Pulmonary Alveolar Proteinosis: A Case Report.

Autoimmune pulmonary alveolar proteinosis (PAP) is a rare lung condition characterized by the accumulation of surfactant proteins within the alveoli, leading to respiratory distress. We describe a 49-year-old female homemaker with a history of passive smoking and exposure to wood smoke and pigeon droppings. She presented with a dry cough and progressive dyspnea, experiencing significant deterioration in her condition over one year.

Pulmonary Manifestation of Granulomatosis With Polyangiitis: A Challenging Case Presentation.

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a rare and potentially life-threatening autoimmune disease characterized by antineutrophil cytoplasmic antibody (ANCA)-associated vasculature inflammation. It presents as a systemic autoimmune disease with necrotizing granulomatous inflammation and pauci-immune small vessel vasculitis. This case initially posed a diagnostic challenge due to its atypical presentation and was misdiagnosed as hypersensitivity pneumonitis.

Pneumothorax Revealing the Rupture of a Primary Pleural Hydatid Cyst.

Primary pleural hydatid cysts are exceptionally uncommon, even in areas where this parasitic infection is prevalent. The occurrence of pneumothorax can serve as an indicator of this condition, presenting a challenge in both diagnosis and treatment when compared to more common causes of pneumothorax. Moreover, hydatid serology often yields negative results, further complicating the diagnosis.

E-cigarette and Vaping-Induced Lung Injury (EVALI) Long Taken for Miliary Tuberculosis: A Rare Cause of Interstitial Lung Disease.

Electronic cigarettes, a recent and burgeoning product, are gaining traction among the general population. However, despite their growing popularity, there is a lack of comprehensive research on their potential health risks. A prominent concern is EVALI (electronic cigarette or vaping product use-associated lung injury), a newly recognized condition currently under intense investigation.
