The main symptom of nodular vasculitis is the appearance of small, slightly red nodules on the skin, sometimes felt as mild pain and tenderness. This condition is most commonly seen in women, aged 30-60 years, and occasionally in men. The lesions are usually small nodules of bright red, dark red or normal skin color, all the way to relatively large infiltrated plaques with round or oval shape. Initially occurring on the lower legs and similar in size to a fava bean, the nodules are sometimes hard, with red and hot surface skin and mild or significant pain. They also usually disappear after 2-4 weeks without treatment, leaving a pigmented or fibrous nodule of the skin, which usually does not ulcerate. The nodules flare periodically, sometimes spreading to the feet, thighs, or upper extremities, and may cause joint pain or lower extremity tenderness and weakness, with little involvement of other systems or organs.
