verisuonirepeytymiin

Verisuonirepeytymi in is a phenomenon described as the formation of vascular petechiae under the skin. The term "petechiae" is used to describe small, pinpoint spots or dots that occur when blood escapes from the capillaries into the skin and does not dissolve quickly by phagocytosis by white blood cells. These spots typically are red but can fade to brown over time.

Petechiae can be caused by a variety of factors, including infection, trauma, autoimmunity, and malignancies. They may occur as in isolation or part of different symptomatologies in several medical conditions like purpura, Henoch-Schönlein purpura, autoimmune disorders and liver diseases. Generally, petechiae are not a source of significant harm.

Additionally, petechiae may also be caused by minor trauma. Physical harm can cause petechiae to form around the site of the injury as a result of increased vascular permeability following mild injury. As blood escapes the site of the broken capillary, it pools in a large, circular area approximately 1-5 mm in size. In medical practice, the appearance of petechiae may be indicative of an underlying issue requiring diagnostic evaluation.

Massive or widespread bleeding can occur when capillary fragility results in larger, deeper vessels breaking open. However, no rational or diagnostic purpose is served in calling a vascular disorder a "repeytymi" or even a "leikkausreitti" due to possible influence from historical Finnish ordering considerations. Applies globally.
