Dermatology/Is it still considered petechia if there are only a few red dots spread out around the arm?


Little red dot
Little red dot  
I have a few red dots (less than 10) on my left arm. Some are close, some are really spread out. But none of them are "clustered" in any way. I read that petechia can be caused by low platlet counts but a little less than a year ago at my physical when my blood was tested my platlets were perfect. I'm only 17 so I don't know why I would have "cherry anigmas" all over, although I do have a few of those cherry things on my stomach but a dermatologist told me not to worry about them. So, would what I explained fit under "petechia"? And if not what do you think they could be. I'll include a picture of one.

The skin lesions are most likely angioma. Angioma or haemangioma (American spelling ‘hemangioma’) describes a benign (non-cancerous) overgrowth of blood vessels in the skin. Angiomas are due to proliferating endothelial cells; these are the cells that line blood vessels.
