case_images: A 25-year-old Hispanic male with HIV infection (CD4 count <40 cells/muL, viral load 307 copies/mL on antiretroviral therapy) and pulmonary KS on chemotherapy presented with progressive dyspnea and cough productive of rubbery red and white material (Figure 1).
case_images: Computed tomography of the chest showed diffuse peribronchovascular consolidative opacities with surrounding ground glass opacities, interlobular septal thickening, and infiltrative soft tissue densities throughout the mediastinum. There is also a linear filling defect in the bronchus intermedius.
