Livedoid vasculopathy (LV) is a cutaneous manifestation of several diseases that lead to noninflammatory thrombosis of dermal vessels. We report the case of a 26-year-old female with a 4 years and 8 months-old history of diagnosis of LV and a non-healing ulcer of more than a year of evolution. Because of refractory response to standard care, low-pressure hyperbaric oxygen (LPHBOT) was added to the therapeutic scheme (azathiopine 2.

MICA is recognized by the activating immune cell receptor natural killer group 2D (NKG2D), providing a mechanism by which immune cells can identify and potentially eliminate pathological cells. Immune recognition through NKG2D is implicated in cancer, atherosclerosis, transplant rejection, and inflammatory diseases, such as rheumatoid arthritis.
