1. Abstract
Necrobiosis Lipoidica (NL) is a chronic, idiopathic, granulomatous dermatosis, of collagen degeneration. Yellow-brown, centrally waxy, atrophic, telangiectatic plaques, are its usual presentation, mostly over the pretibial region, with an elevated violaceous rim, regularly bilaterally, but rarely unilaterally, with or without ulceration. Childhood-onset, bilateral NL in typical locations, are rarely reported, but unilateral involvement has not been reported before. We report a case of type 1 diabetic 9-year-old boy, who developed at the age of 2 years, which also has been not reported before, three centrally, atrophic yellow plaques with telangiectasia, and brown elevated rim over the right pretibial area only, while the left side is not affected.
