Some common skin tag look-alikes include benign lesions such as seborrheic keratoses, common moles, warts, neurofibromas, and a fatty mole called nevus lipomatosus. While extremely rare, there are a few reports of skin cancers found in skin tags. Skin cancers like basal cell carcinoma, squamous cell carcinoma, and malignant melanoma may rarely mimic skin tags, as described above.
Moles are pigmented skin growths, also called nevi, that can appear anywhere on the body singly or in groups. Almost all adults have at least a few and some may have up to 40. Normally appearing as a dark brown spot, a mole may also be blue, black, pink or flesh-colored or may be raised and highly visible. Some may change over time or even gradually disappear. Whatever their color or shape, most moles are harmless and cause no symptoms other than discomfort when they rub against something.
