Circular Skin Rash Not Ringworm
(Brandon SD, US)
circular skin rash on arm is not ringworm
We are at our wits end about this skin care problem. My boyfriend started to develop spots on his hands about a year ago now. After a while the spots began to spread and started to become visible on the elbow of his left arm. Some of the spots on his hands and arms are in the pattern of a complete a circle. These skin rash spots are raised, red, and rough but are not scaly. I have included a couple of pictures that perhaps better describe or illustrate the symptoms of the skin rash problem that by boyfriend has been suffering from. The photos clearly show the red circular pattern of the skin rash. Note also that there a several different sized circles, as well as some irregular raised red lines on the skin.
He has been to see a dermatologist on two separate occasions in order to address or diagnose this skin rash problem. The skin doctor took some skin scrapings and examined the skin under the microscope and established that the skin rash, although it appeared to be ring worm, was not a ring worm skin problem at all. The dermatologist even took a biopsy of the affected skin area and determined that is was not skin cancer. My boyfriend swears that this skin rash problem was caused from a bug bite that he got at some point. However, the circular skin rash has gradually started on the other arm, and is in fact getting worse.
Fortunately, the rash does not itch. It is just very unsightly. The one scab area as shown in the photo is from the biopsy. Some days the rash spots on his arm are redder than on other days. My boyfriend is a Type 2 diabetic and a heart attack survivor and so he does take medications for these health issues. The dermatologist first said the rash was caused from perfumes and soaps. However, we changed all of that stuff to no avail. He put my boyfriend on a steroid cream and moisturizer but this does not seem to be working. He has also tried some natural remedies such as drinking raw cider vinegar and applying the vinegar to the skin rash. He has also applied tea tree oil to the rash, but regardless of what is tried, there is no change in the circular skin rash. Does anybody have any ideas of what this rash could be and how to get rid of it?
