2. “Pasted On” Appearance
Melanoma has very different visual characteristics when compared to lesions caused by seborrheic keratosis. Melanoma looks like a weeping sore in its most aggressive stages, and they often look like dark moles that don’t match the same color or shape as other moles on the body.
Lesions caused by seborrheic keratosis look like they are pieces of sand “pasted on” to your skin. The growths grow very slowly over time and become more prevalent if you spend time in the direct sunlight. It’s common for fishermen and people that work in the intense sunlight hours of the day, to develop seborrheic keratosis lesions.
Middle-aged men are most at risk of developing seborrheic keratosis and risk rises with age. The skin disorder is somewhat hereditary, and the risk of developing the condition increases if more than one family member or relative has it as well. Visit your doctor and ask them to examine your skin, as you may have lesions on your back as well.
