A unique case of extranodal marginal zone lymphoma with synchronous pulmonary and dermatologic manifestations.

An 89-year-old male with a medical history of non-ischemic cardiomyopathy was initially admitted with acute hypoxic respiratory failure attributed to heart failure exacerbation. Aside from progressive dyspnea, a non-pruritic, non-painful rash and constitutional symptoms were reported. Initial work-up was remarkable for normocytic anemia, lymphopenia, mild hypercalcemia, and elevated inflammatory markers.

Metastatic pulmonary calcification in a renal transplant recipient.

Metastatic pulmonary calcification (MPC) is a metabolic disorder characterized by an ectopic deposition of calcium in the lung parenchyma, prevalent in patients with chronic kidney disease. A combination of parenchymal lung abnormalities on high resolution chest computed tomography (CT) and pulmonary radiotracer uptake in Tc-methyl diphosphate (MDP) bone scintigraphy can establish diagnosis of MPC. We herein present a case of MPC with documented stability of chest CT abnormalities after renal transplant.

Evolution of SARS-CoV-2 related pneumatoceles: A case report.

Pneumatoceles are thin-walled, air or fluid-filled cysts within the lung parenchyma typically formed due to inflammation or bronchial injury from infectious and non-infectious etiologies. To our knowledge, there are only a handful of cases in the literature reporting complicated pneumatoceles as a result of acute respiratory distress without the use of positive-pressure ventilation. We present a unique case of a 34-year-old male who rapidly developed complicated pneumatoceles associated with SARS-CoV-2 pneumonia, without positive pressure ventilation, with complete resolution after conservative management.

Sleep associated gas exchange abnormalities in children and adolescents with habitual snoring.

Study Objectives: The purpose of this study was to describe the prevalence of polysomnographically diagnosed OSAS and to describe the severity of sleep associated gas exchange abnormalities (SAGEA) in habitually snoring children. We hypothesized that there would be a high prevalence of OSAS in obese children with habitual snoring and that the most overweight children would have the most significant SAGEA.

Design: Retrospective chart review.
