You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply.
Can you upload a photo(s) of this "wart" to our conversation? You can use the paperclip icon in the toolbar above your message box (if you can see that icon) or you can use an external app such as dropbox.com/
I can be more accurate for you if I can see what you're seeing.
Thank you. Give me a moment to review it, please...
I'm having difficulty assessing its height. It appears to be flat and scabbed over but that appearance may be artifactual. I would shave around this skin lesion and scrub away any scab/discharge in order to better evaluate what it indicates. At that point, a topical medication might be prescribed but I suspect surgical excision would be necessary. At Betty's age, I have to be concerned about skin cancer.
I would appreciate additional photos with the hair wet down and away from this skin lesion that has been cleaned as mentioned above.
Thank you! If it hasn't changed for years and she isn't bothered by it, I agree, just keep it clean. There's no need to medicate it.
Better! This appears to be an ulcerated sebaceous gland tumor - nodular sebaceous hyperplasia, sebaceous epithelioma, or sebaceous adenoma. Erroneously called "warts", they're all benign and of cosmetic importance only. They don't respond to topicals. Just keep it clean. Please continue our conversation if you wish.
It's my pleasure. Thank you for your kind accept. I appreciate it. You may receive an inappropriate follow-up from the site ostensibly sent by me. It wasn't and I apologize in advance should you receive it.
