Is there a connection between lipoma (fat lump under skin) and hypothyroidism in dogs?

I have a dobe who is taking hormone medication for hypothyroidism. Recently, I found a small bump on her abdomen near her back leg. I have a vet appointment on Friday, but meanwhile, I've been doing some research on what it might be. Hopefully, it's just a benign fat lump, but does anyone if there's a connection between her thyroid problem and this new bump? Will it go away on it's own or will it always be there?

I've had both non-hypo dogs and hypo dogs and all of them got lipomas as they aged. Hypothyroidism is extremely common in older dogs and so are lipomas. I don't think there's a link. My step-mother-in-law's hypothyroid dog had none and recently died at 14. My mother-in-law's dog died of cancer at 12 and was not hypo. He had tons along with cancer. I do think it is more common in certain larger breeds. They don't go away unless removed. Most don't need to be removed.
