Granulomatous variant of chronic pigmented purpuric dermatoses: report of four new cases and an association with hyperlipidaemia.

Four patients presenting with chronic pigmented purpuric dermatosis (CPPD) on the limbs were found to have granulomatous inflammation superimposed on the pathological changes of CPPD. Three of the four patients had hyperlipidaemia. Therefore, the granulomatous reaction observed could be associated with hyperlipidaemia. Whether it occurs only in Asian people or not needs further observation.
