<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi i am a 19 year old female. about 6 months ago i noticed a lump under my skin in my lower left abdomen. i can not see it through my skin but i can feel it under my muscle. recently i noticed similar smaller lumps around it. it is not painful just tender to the touch. any advice on what this could be?  <response>: Hi.based from your description, it could be any of the following lesions: a fibrous fibrous tissue deposit, a lipoma fatty deposit or a cystic lesion sebaceous or gelatinous type. Other tumor lesions must also be ruled-out. Diagnostics such as imaging and a tissue biopsy may be recommended. Management medical andor surgical will be directed accordingly. Hope this helps.
