A seven-year retrospective study was done on histologically proven nodular vasculitis presenting at the National Skin Centre, Singapore. We collected 25 patients and found that they differed from the classical European model. They most commonly involved the shins and did not ulcerate. A tuberculous aetiology accounted for 28% of cases. Useful indicators of tuberculosis were a past history of tuberculosis, an abnormal chest X-ray and a strongly positive Mantoux test.
