Mole removal grew back and an inch away from the site there’s a white bump - what could it be? (photos)

It's not uncommon for a mole to grow back if the removal was not complete, especially if the procedure was performed for cosmetic reasons and did not involve excising a margin of surrounding tissue. The dull ache and the new white bump you are experiencing could be due to several possibilities:

Scar Tissue: Sometimes, after a mole removal, scar tissue can form and may feel like a lump. This can cause discomfort or aching.

Cyst: It's possible that a sebaceous cyst or another type of benign cyst has developed near the site of the previous mole removal.

Recurrent Nevus: If the mole was not completely removed, the remaining cells can proliferate, leading to a recurrent nevus. This might appear different from the original mole.

Infection or Inflammation: Occasionally, an infection or localized inflammation can occur after a procedure, leading to soreness and the formation of a bump.

Other Skin Conditions: There could be other dermatological conditions at play, such as a blocked pore or folliculitis, which can present as a painful lump.

Given these possibilities, it's important to follow up with a dermatologist for an in-person examination. They may recommend a biopsy of the new bump to rule out any serious conditions and ensure appropriate treatment. If the pain persists or if you notice any changes in the size, color, or shape of the mole or bump, seeking prompt medical evaluation is advisable.
