Abstract: | A 55-year-old woman presented with a 5-year history of livedo racemosa on her limbs. Histology showed vasculitis of medium-sized arteries with a circumferential, hyalinised, intraluminal fibrin ring. Her laboratory investigations did not indicate any underlying systemic disease. The findings were consistent with lymphocytic thrombophilic arteritis (LTA), alias macular arteritis, which is a recently described entity. The importance of LTA lies in the fact that it is a close clinical and microscopic mimic of polyarteritis nodosa (PAN). LTA is believed to be a distinct entity by some and as a form of PAN by others. We have discussed this case in our report. |
