<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, I have recently noticed a green dark gray colored lump, that is sticking out of the skin of the top left of my toe. I can see the lump under my skin as well. There is a ring around the lump as if it had burst through the skin. It appears to look somewhat cracked and has numerous black dots inside of it. I really wanted to know what this is. Thank you for the help.  <response>: Hi. Thanks for your query. Noted your history and understood your concerns. Greendark gray lump with multiple black dots and appearing as if coming out of the skin and the part being under the skin indicate the probable cause as viral wart or keratin horn or an infected epidermis cyst. This can be treated in the following way:Consult a General Surgeon for clinical evaluation, examination. If this is due to viral wart, it can be treated by chemical cautery, electric cautery or surgical excision. Your Surgeon may advise you the proper way or send you to the Dermatologist for further management. Please do not try anything at home.
