[|Human|] Hello... This may be nothing, buy my husband (healthy 71) just brought to my attention a lump that is at the top of his thigh just under the crease of his torso and opposite his scrotum. It is about 3/4 long and 1/2 wide, dark purple/brown, it is quite solid and just under the surface of the skin, does not collapse as a vein would with pressure, and doesn t move freely. It causes no pain. Is this something we should have checked out or wait a week or so to see if it changes? Thank you, XXXX
[|AI|]  Hello, The narrated lump on the crease between the torso and thigh indicates soft tissue lump as lipoma or sebaceous cyst most likely which may pause lack of mobility due to joint proximity and limited space. Though there is not an emergency, a planned visit to his family doc for primary check up of the lump is best warranted to avoid any hassle in the latter on period of growth of lump if there. Hope I have answered your query. Let me know if I can assist you further.
