My mother 80 yrs old
has a circular bump on the point of her chin.
We looked at ring worm and although similar in shape she does not have the red or white spots and no itching or pain. Her husband is in a hospice setting and she spends a lot of time there around him and other patients. She has supressed immune system from treatments for fairly severe RA and had been diagnosed with pulminary fibrosis. We are going to treat with lamisil to eliminate the ring work if that is what it is.
