The Drs: What is a Cutaneous Horn & How to Prevent Ringworm in Puppies


The Doctors: It is Possible for Humans to Grow Cutaneous Horns

Allison contacted The Doctors via Facebook because she has a cone shaped like wart growing on her and she knows it is not a skin tag since she has had one before and this looks completely different. She wanted to know if it could be something other than a skin tag growing on her.

Well, Allison. You may growing a horn. Dr. Anna Guanche said it is entirely possible for humans to grow something called a cutaneous horn, a growth that is made of carotene, the same stuff your toenails are made of. She said cutaneous horns have been known to grow as big as nine inches long before falling off and potentially growing back.


While the horn would be visually unappealing, it is not the may concern. Dr. Guanche said her main concern lies with the base of the horn because 20 percent of cutaneous horns will develop into skin cancer at the base.

Skin Tags Are Not the Same as Cutaneous Horns

While skin tags are also growths like cutaneous horns, they are harmless. Dr. Guanche said skin tags can grow anywhere skin rubs together and they can be removed if they become bothersome.

The Doctors looked at the difference between a cutaneous horn and a skin tag and they went over the best ways to prevent the transfer of ringworm.

Tiffany just bought a new puppy and she wants to know if it is true that dogs can pass some illnesses to their owners. She wanted to know what can be passed along, how they can be spotted and how to prevent the transfer of disease.

Veterinarian Dr. Karen Halligan said ringworm is common in puppies and it can be transferred to a human. While the fungus is contagious it is very treatable.

Hook Worms Can Kill Puppies

Dr. Halligan was more concerned with hook worm because it can be spread to humans and because it can kill a puppy by bleeding it to death. She explained the hook worm lives in the blood stream of the puppy and sucks blood from the intestines. For a small dog, the hook worm can suck so much blood they can kill the puppy.

Dr. Halligan’s best prevention tip for both of these diseases is taking the puppy to the bet every two to four weeks for a checkup and to have them de-wormed.
