Diagnostic Considerations

Also consider the following:

  • Hemangioproliferative diseases (eg, capillary and cavernous hemangiomas)
  • Hemosiderotic fibrohistiocytic lipomatous lesion [11]
  • Pigmented purpuric lichenoid dermatitis of Blum
  • Purpura annularis telangiectodes (Majocchi purpura)
  • Stewart-Blufarb syndrome [12]
  • Vasculitis

Pseudo-Kaposi sarcoma can be misdiagnosed as AIDS-related Kaposi sarcoma (as a relatively greater prevalence of AIDS-related Kaposi sarcoma exists). Treating acroangiodermatitis as Kaposi sarcoma (eg, with grafting and irradiation) is another diagnostic pitfall. A case report described acroangiodermatitis of the plantar aspect of the foot related to chronic venous insufficiency, misdiagnosed for 2 years. [13]
