<s>[INST] Hello. I recently (within the last year) noticed a small--less than 2 cm diameter--hard lump under my skin on my upper thigh. Sometimes if the area gets scratched, it will bleed, but I still feel the lump. I have not discussed this with my primary care doctor yet. Also, the lump appears slightly whitish. [/INST] Hi. Thanks for your query. Noted your history of a lump in the upper part thigh. It can most probably be :An inguinal lymph node or a sebaceous cyst or a lipoma. Clinical examination can get a diagnosis and hence you have to show this to your Primary care as the treatment of all the different conditions is different. Do not scratch over it, this can increase the infection. Get further tests as guided done immediately so that a proper diagnosis can be done. </s>
