What is the appearance of lesions in Kaposi's sarcoma?

• A. White patches
• B. Red nodules
• C. Purple lesions
• D. Yellow plaques

Answer: (C)

In Kaposi's sarcoma, the lesions typically present as purple or violaceous lesions on the skin or mucosal surfaces. These lesions are due to the proliferation of endothelial cells and the accumulation of blood within the skin, giving them a distinctive reddish-purple coloration. The appearance of the lesions is a key clinical feature that helps in the diagnosis of this condition, which is associated with Human Immunodeficiency Virus (HIV) infection and other immunocompromising conditions. The purple hue is particularly significant, as it differentiates Kaposi's sarcoma from other skin lesions and conditions that may feature nodules or patches in different colors. This characteristic appearance is crucial for healthcare providers as it guides their assessment and management of patients.
