Brief Answer: Could be a benign lesion Detailed Answer: Hi, Thanks for your query. Kindly provide some more details on the condition for better understanding. How big is the lesion now? How big was it at onset ? What is the rate of its growth ? Do you have itching or pain associated with the spot? Have you used any medication for the same? Its less likely for a cancer or a sarcoma to exist for 6 years without getting complicated. I suspect it to be a benign lesion of trivial danger. Waiting for your response,

Brief Answer: Nevus Detailed Answer: Hi, Thanks for the information. Based on the info provided I suspect the lesion to be a bening condition called Nevus. This needs no treatment unless it starts growing faster. Diagnosis can be confirmed by a biopsy test. You can get it done with any Dermatologist you consult. Do attach an image of the lesion here if possible. I shall be much sure if I have a look at the lesion. Regards,
