Dermatologist: It's a good idea to consult a dermatologist in case more lesions appear in the future, but I wonder if these spots could have been caused by a bite from some sort of insect even though there was no itching. If no other skin spots appear a systemic cause is unlikely. ...Read more

I have a raised purple spot on my leg which has been there for quite some time now. Around it are rash-like marks and it all itches. Any clues?

Exam needed: If the discolored lesion is only days old, it could have been an insect bite with some leakage of blood under the skin. The associated itching makes this more likely but the lesion would clear after 10 days or so. Cortisone type ointment would relieve the itch. If this lesion has been present for weeks it's best to have it examined by your physician or dermatologist. ...Read more

I have a very light blue/purple/gray spot on my leg. It is very small. I thought it was a bruise but it does not hurt. Could it be skin cancer?

And remember to protect your skin. Wear sunscreen with an SPF of at least 30 and try to cover up as much as possible when outdoors for prolonged periods of time. ...Read more

My mother has a big black purple ish spot on her leg. I don't think its a bruise. I remember my friend said to ask a docotor cause it might be a clot?

Go see her doctor: Take your mom to see her family doctor who can make the diagnosis. There's not enough information w/o seeing spot so all I can do is speculate which does you/her no good. Be sure to bring in all medications (prescription ; over-the-counter) as well as dietary supplements eg herbs, pills, powders, etc, as spot may be a drug-drug-supplement interaction. ...Read more

I have 6 spots on my left knee which itch a lot. Do you have any idea what they could be?

Get it checked: Are they new? Perhaps you have an allergic skin rash, or a local infection. Apply cool compress. To see if that gives some relief. I would not apply any medicines to the skin if there is broken skin, rash or blisters until you have been checked. The medicines might aggravate your symptoms or muddy up the appearance making accurate diagnosis impossible. Hope that helps. ...Read more
