What causes small flesh-colored bumps on the neck?

Hello, small skin growths on the neck can arise from various causes, such as acanthosis nigricans, photosensitive dermatitis, or miliaria (heat rash). If the lesion appears to be elevated above the skin surface, it is more likely to be a melanocytic nevus (mole) or a skin polyp. If located beneath the skin, it is most likely related to lymph node pathology. We hope this information is helpful to you. Wishing you a pleasant and healthy life!
