      Hi Steve,
      Thought I’d start a thread for odd looking lumps and bumps.

      Scanned this young guy recently that has a recurring lump (his third time now) at the base of the his left skull.
      I was thinking maybe necrotic lymph node but not too sure.
      Was non compressible and had very minor vascularity. NAD in the bilateral submandibular, parotid and cervical chain lymph nodes.

      Any thoughts?

      Thanks!

      This thread will be interesting as there are so many little miscellaneous lumps and bumps all over the body that are hard to define.

      This one is such a case, I am not sure what the diagnosis is going to be.
      It is in the subcutaneous fat layer.

      It looks to contain fat,

      Could it simply be fat?

      It does not look typical of fat necrosis , but this should get a mention.

      AVM is another possibility, although I would not expect it to be that firm on palpation. Some AVM’s have lots of Doppler flow but others have very little.

      Ingrown hair?

      Epidermoid?

      Let me know if you discover anything,

      Steve

      Hi Steve,
      I’ve seen several lumps like these in the forehead soft tissue and I’ve always thought they are Lipomas.
      Are they Lipomas? If so, why do they always seem ‘deep’??

      Thanks,
      Samuel.K

      Hi Samuel,

      Yes, I see them like this as well,

      I am happy to suggest they are lipomas and follow them up.

      A CT scan can prove its fat if required.

      But if it is not changing much over time it is consistent with a lipoma.

      As for the location, the scalp has several layers (see attached diagram) so if it is between two of the deer layers it will appear like your case.

      Steve
