Brief Answer:
Nevus

Detailed Answer:
Thank you for contacting HCM with your health care concerns

You have a lesion on your leg that you are concerned about. This is called a nevus or a mole. There is some aspects of this lesion that makes me more cautious as to what it is. More than likely it is a benign lesion but be cause of some of its irregularity in the borders I would recommend that you have it removed. It maybe an atypical nevus which brings a higher risk of malignancy. I would recommend that you see your medical provider or a dermatologist and have them look at it and perhaps have it removed. At this point I can't give you any more information until you have it seen or removed and biopsied.

I hope I answered your question. Please contact us again if you have any additional questions.
