Hematoma vs. hyperemia vs. hemangioma

  1. 0
    I realize that this is probably a very loaded question, but here goes -

    Could anyone explain to me the difference between the following 3 terms: hematoma, hyperemia, hemangioma. Esp the first 2.

    I have read the definitions in my books. I think I understand them to a certain extent, but I am kind of wanting to hear it put in layman's terms. Would esp like to hear from any graduates out there who have already worked with and seen these 3 conditions, and what causes them, etc. (Of course, all responses are welcome.)

    Again - very loaded question, I realize. But if you submit an answer, I'll give you a cookie.

    Hyperemia is an increase in blood flow to a part of the body, where a hematoma is a collection of blood under the skin (as in an injury).

    Neither of these should be confused with hyphema, which is a pooling of blood in the anterior chamber of an injured eye.

    hyperemia describes the increase of blood flow to different tissues in the body. it can have medical implications, but is also a regulatory response, allowing change in blood supply to different tissues through vasodilation

    a hemangioma is an abnormal build up of blood vessels in the skin or internal organs.[1] it is also described as a congenital benign skin lesion consisting of dense, usually elevated masses of dilated blood vessels".

    I see that the term "hyperemia" is used in webmd's section on pinkeye. However, I don't think hyperemia refers only to eye redness, does it?
