Pyoderma gangrenosum is a rare, non-infectious and destructive skin disease. Its exact etiopathogenesis is not clearly understood and is believed to be due to immune dysfunction. Several theories have been postulated; however none are consistent in all patients. Pyoderma gangrenosum mostly affects adults and rarely in children. An underlying systemic disease is often seen in most of the cases. A three- year- old male child presented with a nonhealing ulcer over left thigh. Clinical features, histopathology, other investigations and dramatic response to corticosteroids suggested a diagnosis of idiopathic pyoderma gangrenosum. Associated idiopathic thrombocytosis was also seen. Idiopathic pyoderma gangrenosum is very rare in children. Idiopathic pyoderma gangrenosum associated with idiopathic thrombocytosis and keloidal scarring has not been reported earlier
