[|Human|] I have a lump on my big toe and it has lots of little black spots on it. I have had it for well over a year now. Whenever I try to get rid of it, it always seems to bleed. It is a very embarrassing problem. It hurts often and gives me lots of pain. I am just wondering what it is.
[|AI|]  HiT hanks for your query. Based on your query, my opinion is 1. Pigmented lumps/ swelling needs to be evaluated for lesions like tumors of melanocytes.  (melanoma)2. Other possible cause could be fungal infection of foot like Madurai mitosis which discharges black granules from the lump.3. If there has been an increase in the size of the lump/ painful/ increased pigmentation, then a fine needle aspiration/ biopsy examination is needed immediately. Hope this helps. Regards
