Case 3: Kaposi's Sarcoma

You answered:

	Visceral, but not isolated cutaneous Kaposi's sarcoma, is an AIDS-defining illness.

This answer is incorrect. Any form of Kaposi's sarcoma, cutaneous or visceral, is an AIDS-defining illness.

	In some patients, highly active antiretroviral therapy alone causes significant improvement of Kaposi's sarcoma lesions.
	Human herpes virus type 6 (HHV-6) is the causative agent of Kaposi's sarcoma.
	Liquid nitrogen cryotherapy is generally ineffective for management of localized cutaneous Kaposi's sarcoma lesions.
