White moss on ear lobe : infection or fungi ?

[ManueB]

I have had several birds that have only one colored earlobe, even few that developed later in life.
I'm guessing melanoma, since it appears to have a grown from a smaller size, it's spreading and slightly raised. The fact that it's not hard or flaking off, sort of makes me think it's not an infection or a surface issue. But I don't know, it's hard to tell from pictures.

Thanks for explaining. Yes, it's hard to tell on the pictures, my phone isn't great, but it's also hard to say for real. It could be just loose skin, it doesn't feel like it's irritated or painful, but i’m not 100% sure.
She is acting unwell but it doesn't really seem to be related to that thing.

The cream I ordered has been shipped so it should be there on Wednesday. Unless there has been some major developments I will give it a try.

And finally, I noticed today one of my other ex-batts has now also a tiny cyst like Blanche used to. I have no clue when it appeared.
