Is it normal to have a mike suddenly appear on the palm side of my finger?

Hi Anon,

Were you sure that it was never there before? Or did you just notice it?

It could be normal and nothing to worry about-- I found some information on our site regarding moles:

Most people have some benign moles that appear at birth, childhood, or adolescence.

Benign moles, which can appear anywhere on the body, are usually:

Dark brown, but can also be yellow-brown or flesh tone
One color
Round or oval with distinct edges
Flat and smooth, but may occasionally become raised, rough, grow hair, or change color over time
Signs that a mole may be atypical include:

Sudden change in size, color, shape, texture, or sensation
Large size (¼ inch or more across, about the size of an eraser at the end of a pencil)
Many melanomas are smaller than this size.
A mixture of colors, often including black
Irregular edges
Abnormal surface that is:
Scaling
Flaking
Oozing
Bleeding
Open with a sore that won't heal
Hard and raised lump
Itchy, tender, or painful
Abnormally colored skin around it

If any of the atypical signs apply to you, then contact your dermatologist for a detailed evaluation. It is actually a good idea to schedule an appointment and have your dermatologist inspect every single mole on your body from head to toe-- it's better to be safe than sorry.

Best Wishes!
