Chinchilla ear problem!?

Hi there, I just noticed this round thingy inside my chin's ear, the back or the ear seem normal.

Thanks a lot! Your input is much appreciated.

I posted the same question on the Small Animal forum, but I guess I should post it here instead, here's the link to the original post with picture.

Thanks.

From the photo I was unable to determine if the lesion is raised or not, has the appearance of a blister, or is scab-like.

Since your chin is a bit older the lesion could be a dermal mass, such as a sebaceous cyst, adenoma, infection (fungal or bacterial), or skin cancer.  

Like all masses, it should be biopsied by your veterinarian.
