While classic skin tags are typically very characteristic in appearance and occur in specific locations such as the underarms, necks, under breasts, eyelids and groin folds, there are tags that may occur in less obvious locations.

Other skin growths that may look similar to a skin tag but are not tags include moles (dermal nevus), nerve and fiber-type moles (neurofibromas), warts, and "barnacles" or the so-called "Rice Krispies" (seborrheic keratosis).

Warts tend to be rougher, with a "warty" irregular surface whereas skin tags are usually smooth. Warts tend to be flat whereas tags are more like bumps hanging from thin stalk. While warts are almost entirely caused by human papilloma virus (HPV), tags are only sometimes associated with HPV.

Groin and genital lesions resembling skin tags may actually be genital warts or condyloma. A biopsy would help diagnose which of these growths are not skin tags. Very rarely, a basal cell skin or squamous cancer or melanoma may mimic a skin tag, but this is very uncommon.

While typical skin tags are not usually seen in the vagina or in other moist, mucosal surfaces, there are other types of benign polyps that occur in these areas. Irritation polyps or soft fibromas may occur on vaginal areas, mouth, and anal skin. Skin tags most commonly occur on dry skin like the neck, armpits, and groin folds. Genital warts, which are growths caused by a sexually transmitted virus HPV, need to be considered in the possible diagnosis for growths in genital areas.

Skin tags may infrequently occur at the external genitalia like the labia majora and labia minora. These growths may be caused by normal friction from underwear, panty liners or feminine sanitary products, sexual activity, or masturbation. Again, sexually transmitted viral conditions like genital warts may need to be ruled out by tissue biopsy of growths in this area.
