Lump under the chin that doesn't seem to be fat (Photo)

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

There are a substantial number of structures that you can feel under your chin. If you’re feeling around firm dime size nodule, then it’s most likely that you are feeling your submandibular salivary glands. You can Google that term and get an idea of where they’re located. There were also lymph nodes you can sometimes feel in the area as well as the borders of the platysma muscle.
Most people will have some palpable lamp somewhere on their body and it common to find them and they had a neck region.
It does not mean that something is wrong, but you are just noticing normal anatomy most likely.
You can certainly discuss this with your primary care doctor next time you see them.
Indication for needing a specialty evaluation would be if something is changing or growing in size.
