What condition is characterized by chronic rough, dry, thickened skin?

The condition that is characterized by chronic rough, dry, thickened skin is pachylosis. Pachylosis refers specifically to the thickening of the skin, often associated with a rough texture. This condition can result from various factors, including prolonged exposure to irritants or skin inflammation. It's important to note that while eczema and psoriasis can also lead to changes in skin texture and appearance, they are characterized by additional features such as inflammation, redness, and often scaling or oozing. Alopecia primarily relates to hair loss rather than directly affecting the skin's texture. Therefore, pachylosis is the most precise term that describes the specific symptom of rough, dry, and thickened skin.
