Abstract

Subcutaneous fat necrosis of the newborn is an uncommon transient panniculitis which is characterized by asymptomatic, firm to rubbery, purple-red, erythematous subcutaneous nodules and plaques occurring during the first 4 weeks of life. Characteristic histologic findings are areas of fat necrosis associated with inflammation in the subcutaneous tissue and needle-shaped clefts with radial arrangement in fat cells as well as foreign body giant cells. We report a case of subcutaneous fat necrosis in a 9 day-old male who had suffered from hard erythematous nodules on both upper arms.
