Differential Diagnosis & Pitfalls
- Seborrheic keratoses have a "stuck-on" appearance and are usually hyperpigmented.
- Genital warts tends to have a more verrucous or roughened surface.
- Pedunculated neurofibromas usually have a firmer texture.
- Intradermal melanocytic nevus
- Larger papules should be differentiated from solitary neurofibromas, fibroepithelioma of Pinkus (a low-grade basal cell carcinoma), and other cutaneous polypoid lesions.
- External hemorrhoids may resolve and result in perianal skin tags.
- Infantile perianal pyramidal protrusions (IPPP) are most commonly seen in prepubertal girls and present as fleshy, acrochordon-like protrusions of tissue.
