Final answer:
The skin condition described as a 'stuck on' brown or black plaque with a warty appearance is seborrheic keratosis. It is a benign growth that has a variety of colors and is commonly found on the face, chest, shoulders, or back, distinguishing it from melanomas and solar lentigines.
Step-by-step explanation:
The skin condition that appears as a 'stuck on' brown or black plaque with a warty appearance is seborrheic keratosis. Unlike melanoma, which is characterized by large brown or black patches with uneven borders and a raised surface, a seborrheic keratosis tends to look more like a benign growth, with a round or oval shape, a waxy and stuck-on look, and may appear as though it can be easily peeled off the skin.
They can also have a variety of colors ranging from light tan to black and are generally found on the face, chest, shoulders, or back of the body. Solar lentigines, often known as sun spots or age spots, do not have this warty appearance and are instead smooth spots of discoloration on the skin.
It's important not to confuse seborrheic keratosis with melanoma due to the potential risk associated with melanomas. Always consult with a healthcare professional if there is any uncertainty about a skin lesion. This consultation is especially critical if the lesion changes in size, shape, or color, as these could be signs of a more serious condition like melanoma.
