Kaposi's sarcoma is significantly prevalent among men infected with the human immunodeficiency virus, accounting for >90% of all cases. The early presentation of KS typically involves mucocutaneous lesions and lymphadenopathy, and more advanced disease can affect the lungs and other organs. ⋯ Respiratory illnesses are common presentations in the emergency department and are typically benign and attributed to viral causes. However, the emergency physician must always be on the look out for more dangerous causes of respiratory complaints, especially in patients with risk factors and in those found to be refractory to recent treatment for more common illnesses.
