Using the terminology that you learned about lesions, describe polymorphous grouped bullae and polymorphous asymmetrical urticaria in enough detail that someone could picture the areas in their mind without the images. You will need to include the type, shape, distribution, color, size, and presence of drainage in your descriptions for it to be considered complete.
Polymorphous grouped bullae refers to a skin condition characterized by multiple fluid-filled blister-like structures, known as bullae. These bullae can vary in their appearance, shape, and size. They appear in a grouped pattern, meaning that they are clustered closely together in certain areas of the skin.
The bullae may have irregular shapes, with some being oval, round, or even irregularly shaped. They are distributed in a scattered manner across the affected skin, usually covering relatively small areas rather than large expanses. Their color can vary, depending on the stage of the lesion. Initially, the bullae may appear as clear, transparent formations. As they progress, the bullae can become red, purplish, or even brownish in coloration.
In terms of size, the bullae can range from a few millimeters to a centimeter or larger in diameter. They tend to be relatively larger than typical vesicles or blisters. One significant characteristic of polymorphous grouped bullae is the presence of fluid drainage. The bullae may leak a clear or cloudy fluid, depending on the stage of the lesion.
Now moving on to polymorphous asymmetrical urticaria, it refers to a skin condition characterized by multiple raised, swollen areas known as wheals. These wheals can have varying appearances and tend to be asymmetrical, meaning they are not evenly distributed or mirrored on both sides of the body.
The wheals in polymorphous asymmetrical urticaria typically have irregular shapes and sizes. They can appear as round, oval, or even linear formations. The distribution of wheals is scattered and can occur in different areas of the body, including the extremities, trunk, and even the face. They can be present in various sizes, ranging from a few millimeters in diameter to several centimeters.
The color of the wheals is often pale or pinkish, resembling the surrounding skin tone. They can also become red or even purplish in some cases. Unlike the bullae in polymorphous grouped bullae, wheals are not filled with fluid and do not have drainage. Instead, they represent localized areas of swelling in the superficial layers of the skin, caused by inflammation.
By familiarizing oneself with these descriptions, one can visualize the appearance and characteristics of polymorphous grouped bullae and polymorphous asymmetrical urticaria without relying on images.
