Brief Answer:
Small trauma

Detailed Answer:
Hello,

Thank you for using HCM to post your question.
I saw carefully your photo.

It looks like you have maybe hit somewhere that area and its a small hematoma. The area under the eyes its very sensitive and just a small trauma may burst the veins and cause small bleedings under the skin. It should start changing color to green, then purple then yellow and should be healed in around 3 weeks.

If not better in 3 weeks, if larger or any other change, then feel free to follow up with me or see a local dermatologist.

Hope this is helpful.
Let me know if you need more clarifications.
Otherwise please kindly close and rate the answer.

Brief Answer:
Some possible diagnoses

Detailed Answer:
Hello,

Thank you for the follow up question.

If it is not a hematoma, and from the other extra information you have provided, I would think it is a cyst under the skin or an hemangioma (a benign tumor which its made from the blood vessels mostly).
It may also be a chronic folliculitis (an inflammation of the hair follicle there, which has stacked under the skin and has made it's way to heal chronically).

I don't think it is a cancer, if it is that what you are thinking.

I would say that if it doesn't bother you, then do not pick on it or don't do any procedure. But if either for cosmetic purposes or if it bothers you, then the best way to tell which of the above is, its to examine it and also attempt minor surgery so to remove the cyst, stacked hair follicle or hemangioma.

I hope this made a bit more clear the possible causes or the lesion you have.

Feel free to ask if you have other questions or concerns.

Regards,
Dr. Papaqako
