Herein we report the case of a 77 year-old- male who presented with a 6-week history of progressive dyspnea on exertion accompanied by productive cough of yellow sputum and intermittent hemoptysis. His past medical history was significant for Non-Hodgkin\u2019s Follicular B-Cell Lymphoma (NHL). Patient also had biopsy-confirmed cutaneous KS.\u00a0His physical exam was notable for a 2cm firm, non-tender, mobile right submandibular lymph node.\u00a0 Lungs were clear to auscultation. He had multiple violet non-tender skin lesions localized to the lower extremities. CT scan of the chest showed numerous nodular opacities and small pleural effusions in both lungs. A thoracenthesis was performed, showing sero-sanguineous exudative effusions. Histopathology failed to demonstrate malignant cells or lymphoma. A subsequent bronchoscopy revealed diffusely hyperemic, swollen mucosa of the lower airways with mucopurulent secretions. Bronchoalveolar lavage PCR for HHV-8 showed 5800 DNA copies\/mL.\u00a0 It was believed that his pulmonary symptoms were likely due to disseminated KS. \u00a0This case illustrates the potential for significant lung injury from KS. It also demonstrates the use of PCR for HHV-8 to diagnose KS in a bronchoalveolar lavage sample in a case when bronchoscopic biopsy was not safe. Furthermore, this case is unique in that the patient did not match the typical KS subgroups as HIV infection and other immune disorders were ruled out. Recognition of this syndrome is critical to the institution of appropriate therapy. As such, this case should be of interest to a broad readership across internal medicine including the specialties of Pulmonology and Critical Care.<\/ns4:p>","DOI":"10.12688\/f1000research.7137.1","type":"journal-article","created":{"date-parts":[[2015,10,7]],"date-time":"2015-10-07T12:59:10Z","timestamp":1444222750000},"page":"1013","update-policy":"https:\/\/doi.org\/10.12688\/f1000research.crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Case
