[44M] Small, flesh-colored lip bump with post-scab hyperpigmentation

What might be happening

Based on the information you've provided, here are a few possibilities:

• Cold Sores (Herpes Simplex Virus): This is a common viral infection that causes small, painful, fluid-filled blisters on or around the mouth. The blisters usually break open, scab over, and heal without a scar. However, you mentioned that you have not had any similar bumps or sores in the past, and cold sores typically recur in the same location.

• Mucous Cyst (Mucocele): This is a harmless, fluid-filled swelling that occurs on the lip or in the mouth. It may occur after minor trauma to the mouth, such as a lip bite. These cysts are usually temporary and painless, but they can rupture and release a clear fluid.

• Fordyce Spots: These are harmless, small, white or yellowish bumps that are found on the lips or the inside of the cheeks. They are sebaceous glands (glands that secrete sebum to lubricate the skin and hair) that are visible due to their location just below the skin's surface. They are not associated with any disease or illness.

• Skin Tag: A small, soft, flesh-colored benign skin growth that is common in adults. They tend to occur in areas of friction, such as the neck, underarms, and groin, but can also appear on the face, including the lips.

What you can do

1. Keep the area clean and avoid picking at the scab or scar.
2. Protect your lips from the sun as this can darken the scar. Use a lip balm with an SPF of at least 15.
3. Stay hydrated and maintain good oral hygiene.
4. If the bump reappears, consider taking a photo to show your healthcare provider.

What you should look out for

• If the bump reappears or the scar does not fade over time
• If you notice any changes in the size, shape, or color of the bump or scar
• If you develop any new symptoms, such as pain, itching, or bleeding
