Your videos are amazing! I'm a Dermatology resident and these are helping me a lot!

I had nevus sebaceus up until about 5 years ago when I got it removed. It made me very embarassed because anytime someone would do my hair they would talk about my "wart" or say I'd need to go to the doctor. My mom just ignored them and reassured me because I had, has it since I was a baby. But of course I was young and stupid and constantly picked at it hoping it was like a scab and I could pick it off? Anyways eventually I did do the surgery and I feel better though I do find myself touching the scar a lot. I'm glad that there are videos like this that we can now show and educate people!

This what you are doing is fantastic. Thank you very much, its very helpful.

Nevus sebaceus (spelled without the O). A "nevus" (from Latin for "birthmark") without melanocytes. Summary: Yellowish hairless plaque on the scalp of kids. Epidermal acanthosis +/- papillomatosis (can mimic seborrheic keratosis or verruca/wart). Large sebaceous glands open directly to skin surface. Apocrine glands often present in underlying dermis. Can give rise to a variety of (usually benign) adnexal tumors.

Many thanks for another amazing video. I was thinking of requesting you to please make one on histology of hair and various alopecias. Looking at the comments I find I am not alone, quiet a crowd in fact!! So can we hope?

Dude I’m an esthetician and you’re busting me up lol then you had to show the mites lol my son has a nevus sebaceous I’m having a dermatologist look at on March 11th papillominus and verucus looking so these excision and histology videos give me hope. Sry I’m a nerd. Ty 🙏

I just made a video on what it’s like growing up with nevus sebaceus if anyone is interested in watching it! 💞💞

Thanking you

I have one of these in my head ever since birth, I'm 27 years old and I don't like when people touch it I've hit it on things before and it's on the back center of my head I've had CAT scans done before and other things but should I look into getting it removed? Is it going to affect my life later down the line?

Hello! I have a nevus in the left corner of my forehead since birth. I am now 25 years old and a few days ago a blue dot appeared in my nevus. So far there have been no problems. Do I have reason to be afraid? In my country this is unexplored and I am very grateful that I came across your video. Thank you.

Doctor, I have one and everytime a doctor tries to remove it with electrocautery it makes the nevus worse looking. Throughout time it has become more noticeable and I hate it. It's on my face
