Thursday April 15, 2010 I noticed that I had a small brownish orange spot on my thumb on my left hand toward the outside. I examined the spot and found that it was surrounded by dark purple and red lines, and brown spots that stretched from the top of my thumb just under the nail and around almost to the knuckle of my pointer finger. There is no consistency with the shape. Toward the top of my thumb there are rust colored spots, toward the middle are the purple and red lines that appear to pool together in the middle around my thumb knuckle and towards my pointer finger knuckle are about 30 small brown dots a little larger than a pin prick. Through some areas of the pooling there appear to be skin colored straight lines. There is no itching, pain or discomfort. I have not found any other areas like this on my body. I am curious about what this might be. Thank you for taking the time to view my question.

Hello,
Welcome to the ehealthforum and I am really glad to help you out.

I cannot confirm anything without examination,but it sounds like lentigenes. Sun spots or lentigines, are harmless, flat, brown discolorations of the skin which usually occur on the back of the hands, neck and face of people.

Normally these occur in people older than 40 years of age. They are caused by the skin being exposed to the sun over many years and are a sign of sun damage.

The only way to prevent these spots is to use liberal amounts of sunscreen before the age of forty, avoid the sun, and wear protective clothing.

The newest treatment for these spots is an alpha hydroxy acid gel or beta hydroxy acid gel. Retin-A cream, alpha hydroxyacid peels, and liquid nitrogen therapy are other options.

I sincerely hope that helps. Take care.
