Hemorrhages of a diapedetic nature occur in both women and men in almost all layers of the skin, in the subcutaneous fatty tissue, in the reticular structures of the dermis, even in the deep layers of the dermis. In addition, infiltration of diapedesis into the subcutaneous base of blood vessels and developing capillaries and interstitial tissue is possible. The formation of such hemorrhages is facilitated by the involvement in this process of numerous extravascular sources of localization - the skin fat layer, subcutaneous tissue (fiber), connective tissue stroma.
In its outcome, this formation can transform into a hemorrhagic vesicle, gradually increase in size and grow, while filling it with connective tissue and forming a new location for its cells. After which this formation takes the form of a nodular or infiltrated nodule, even resembling a tumor. With prolonged progression of the process, signs of inflammation may appear - redness, swelling and soreness of the changed tissue.
