  Definition: In pathology, “cyst” is the term used for lesions that consists of an epithelium-lined cavity that is filled by material that is generally fluid, mucinous or semi-solid.
  Cysts can arise anywhere in the body and their epithelial lining varies according to the site and tissue they originate from.
  Although cysts can have a bulky tumor-like appearance, the majority are completely benign non-neoplastic lesions. It should, however, be borne in mind that benign and malignant (...)

  UI:774 : acute renal allograft rejection
  Transplant rejection involves several of the immunologic reactions. A major barrier to transplantation is the process of rejection, in which the recipient’s immune system recognizes the graft as being foreign and attacks it. One of the important goals of present-day immunologic research is successful transplantation of tissues in humans without rejection.
  Although the surgical expertise for the transplantation of skin, kidneys, heart, (...)
