###Human: I am having small black spots on my toenail. Does it indicate melanoma? ###Assistant: Hello. I understand your concern. The thing on the chest looks more of a sebaceous cyst, (attachment removed to protect patient identity) which comes and goes even if you pop out the contents as it needs to be excised completely to prevent the recurrence. For the toenail spot, I am not sure that it is melanoma, it can be other things like a subungual traumatic hematoma, or pseudomonas nail infection. Nonetheless, you need to keep observing it for any color or size changes. The two conditions you mentioned do not seem to be related, though. Use the following medication for two weeks, and if it is because of infection it will improve 1. Tablet Ciprofloxacin 500 mg twice a day for two weeks. And avoid tight footwear.
