Little Bit is about 1 1/2 years old. Her weight has been steady, and she acts like herself.
The lump is at the top of her right, rear leg. It is about the size of a dime. I could not see anything unusual when I parted her hair to take a look at it. The skin looks normal and is not raised. The lump moves around a little, but feels somewhat hard. She does not seem to be in pain when I touch the lump.
I do not think the lump has been there very long, as I think I would have noticed it when I pick her up from her cage. This morning was the first time I felt it when I picked her up.
I am going to schedule a vet appointment for her for next week. I hope it is not anything serious.
Graphic pics of cyst on human eyelid and removal ("The content was made up of cheesy materials."):
" The cyst was removed by carefully freeing it from the surrounding tissue. Spillage of the content and incomplete excision can cause chronic inflammation due to spillage of the content. "
So this is a single follical that would be involved for your guinea pig? I'm thinking of the recent thread with the large open sore which supposedly had a whole bunch of pockets of keratious material.
Epidermal inclusion cyst are common cystic lesions that are not cancerous. They don't spread and can't really be prevented (probably have a genetic component). Vet from first link claims epidermal inclusion cysts do not usually contain hair and are not usually congenital lesions.
Vet from first link claims follicular cyst is supposedly "an older name for a cyst" which often does contain hair.
p.s. I was sent a picture of the integumentary system of a guinea pig (sketch). It included several hairs surrounded by a single sebaceous gland. As I noted above, it sounds like not all cysts contain hairs.
