Please give additional information and post clear photographs.

Detailed Answer:
Hi.
Thanks for your query, albeit very short and specific.
Seen the photos which looks to be on the hard palate.
Please give additional information for me to assist you better:
Since when is this present?
What are the symptoms? Any pain or such things that made you notice this?
Any tenderness on pressure?
Any foods that contain spices, bones, fish or so that could have possibly instigated this?
Any other history please.

Awaiting for your feedback.
Picture quality is great but has made the lump a bit out of focus hence try to snap another focusing the lump and post in addition.

Brief Answer:
As detailed.

Detailed Answer:
Thanks for your feedback.
If there are no symptom then this is most probably one of the following:
The commonest cause of small painless lump in hard palate is sub-mucus cyst of the minor salivary gland. Usually is self limiting and needs no active treatment as it does not have any other than surgical excision only if persists or enlarges.
Another rare cause is foreign-body granuloma but is usually painful or tender. This too usually is self limiting as the body takes care of it.

So keep a watch for further development at the moment.
Get a confirmed diagnosis by consulting an ENT or Oral Surgeon if the lump persists or enlarges or show any symptoms - by an actual examination.

Take care.
Please give feedback.
