Rash/ marks on thigh

my mum noticed this rash / marks on her upper inner thigh

She said they were dry (she’s had similar things on her hands before and been diagnosed with dermatitis I think)

She been using the cream on them that she used on her hands

They are not as dry but sort of look like bruises

Not sure if they are or if it’s the skin?

Shes going to ring the doctors tomorrow but we were just curious.

Has anyone had something similar?

Please see pics attached. Thank you
