case_images: Kaposi sarcoma (KS) pulmonary findings. (A) Transverse computed tomography (CT) of the chest showing diffuse bilateral KS pulmonary nodules up to 9 mm in size; (B) Frontal CT of the chest showing KS lesions as described above.

case_images: FIG1
case_images: C-reactive protein of 7.86 mg/dL, and lactate of 3.9 mmol/L (Table 1). Computed tomography (CT) of the chest showed diffuse bilateral pulmonary nodules up to 9 mm in size with a random distribution pattern (Figure 1). 
case_images: Transbronchial biopsy of the lung revealing Kaposi sarcoma. Transbronchial biopsy of the right lung reveals low-grade spindle cell proliferation (black arrow) with occasional vascular "slit-like" spaces, red blood cell extravasation (blue arrow), and rare cytoplasmic eosinophilic globules.

case_images: A transbronchial biopsy revealed KS involving the bilateral lungs (Figures 2-3).
case_images: Transbronchial biopsy of the right lung with immunohistochemical staining reveals spindle cell proliferation positive for human herpesvirus-8 (red arrow).

case_images: A transbronchial biopsy revealed KS involving the bilateral lungs (Figures 2-3).
case_images: Transesophageal echocardiogram displaying a hyperechoic mobile mass (shown with a red arrow), suggestive of cardiac Kaposi sarcoma.

case_images: FIG4
case_images: A transesophageal echocardiogram showed a hyperechoic mobile mass in the right ventricle concerning for KS involvement (Figure 4).
case_images: Kaposi sarcoma (KS) lesions on the hard palate and trunk. (A) Violaceous-brown KS lesions on the hard palate (representative lesion is shown with a white arrow); (B) Brown-black cutaneous KS lesions on the trunk (representative lesions are shown with black arrows).

case_images: FIG5
case_images: Following the pathologic diagnosis of KS from pulmonary tissue, the patient was noted to have a hard palate lesion and multiple lesions on his chest wall consistent with cutaneous KS (Figure 5).
case_images: Hepatic Kaposi sarcoma (KS) on abdominal imaging. Abdominal imaging revealed numerous subcentimeter lesions scattered throughout the liver representing probable hepatic KS. The lesions are very subtle on computed tomography (a) and more apparent on ultrasound (shown with red arrow) (B).

case_images: During this hospitalization, he was incidentally found to have diffuse hepatic hypodensities on CT, likely representing KS liver involvement (Figure 6).
case_images: Worsening pulmonary Kaposi sarcoma (KS) on chest X-ray. Chest X-ray showing worsening pulmonary nodules indicative of pulmonary KS progression.

case_images: Additionally, a chest X-ray showed worsening of pulmonary nodules (Figure 7).
