Solitary incidental primary Kaposi's sarcoma of the glans penis in a patient with no risk factors.

Kaposi's sarcoma (KS) is an endothelial neoplasm, originally reported by Moritz Kaposi in 1872. It most commonly involves the lower extremities. Its clinical presentation and course can be quite variable. We present a rare case of solitary incidental primary KS of the glans penis in a circumcised, immunocompetent male who is human immunodeficiency virus seronegative. The lesion was discovered incidentally when the otherwise asymptomatic male presented to our outpatient department for an unrelated issue and was given a physical examination. To our knowledge, this is the first incidentally discovered case of primary penile KS.
