Secondary organizing pneumonia (SOP) as a sequela to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) usually has a prolonged benign course with a good response to corticosteroids. We present a case series of three patients who developed rapid progression to organizing pneumonia, after initial presentation with SARS-CoV-2. Imaging revealed rapid interval progression of bilateral subpleural ground glass opacities, and lung biopsy showed dense fibroblastic plugs within the alveoli. Two patients were steroid-responsive, and one patient succumbed to his illness despite maximal therapy. We postulate that B-cell depletion and immunosuppression may cause rapid progression to SOP, as all three patients were immunosuppressed and on chronic rituximab therapy.

Ulcerative colitis can present with extra-intestinal manifestations, including interstitial lung disease and primary sclerosing cholangitis. When pulmonary symptoms precede gastrointestinal, diagnosis can be challenging. Consideration of Ulcerative colitis in patients with unexplained lung and hepatic pathology is crucial, as a failure of timely intervention can lead to multiorgan complications.

Anti-melanoma differentiation-associated protein 5 (anti-MDA5) clinically linked amyopathic dermatomyositis (CADM) is a rare autoimmune condition strongly linked to rapidly progressive interstitial lung disease (RP-ILD), a life-threatening complication. We present a 63-year-old female patient with anti-MDA5-positive CADM, who developed RP-ILD with an imaging pattern consistent with organizing pneumonia. She presented with Gottron's papules, periungual erythema, progressive dyspnea, and anorexia.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hyperinflammatory syndrome marked by excessive immune activation. It can be triggered by various factors, including infections, malignancies, and autoimmune diseases, making the diagnosis challenging due to its overlap with other severe conditions.
Case Reports: We discuss two intensive care unit (ICU) cases illustrating the diverse manifestations of HLH and the critical importance of early recognition and treatment.
