title: Classical Kaposi sarcoma: case reports with unusual presentation on the penis and scrotum.
abstract: BACKGROUND
  Kaposi sarcoma (KS) is the most common vascular neoplasm. Any skin area could be involved, including the genitalia. Traditionally, classic KS lesions have a general distribution, often involving skin of the feet and legs, and to a lesser extent, that of the hands, arms, and trunk. KS limited to the external genitalia is extremely rare in HIV seronegative individuals.
  
  
  METHODS
  We report six patients of classic KS with generalized dermal KS lesions.
  
  
  RESULTS
  Two of them presenting with unusual KS lesions on the penis and scrotum beside the other dermal lesions. Patients were HIV negative and human herpes virus eight positive. Histological examination showed classical KS.
  
  
  CONCLUSIONS
  Primary KS of the penis and scrotum is rare but could occur in HIV-negative patients.
