How do sickle cell ulcers typically present on the body?

1. On the upper arms

2. Medial lower third of the leg

3. On the abdomen

4. On the thighs

The correct answer is: Medial lower third of the leg

Sickle cell ulcers typically present on the medial lower third of the leg due to the effects of chronic venous congestion and ischemia associated with sickle cell disease. The sickle-shaped red blood cells can obstruct blood flow, leading to poor circulation and the potential for ulcers, particularly in areas where venous pressure is highest or where the skin is more prone to breakdown. This area on the lower leg is more vulnerable due to the dependence on gravity affecting blood flow and oxygenation. The medial aspect of the leg is a common site for ulcers in many conditions associated with ischemia or venous insufficiency, making it a characteristic location for sickle cell ulcers. The other areas mentioned, such as the upper arms, abdomen, and thighs, are not typical presentations for sickle cell ulcers, as these sites do not experience the same pathophysiological changes relevant to sickle cell disease that lead to ulcer formation.
