A Case of Subcutaneous Fat Necrosis of the Newborn

Subcutaneous fat necrosis of the newborn is a spontaneously regressing disorder of healthy fullterm of postterm infants, characterized by symmetric, firm, erythematous to violaceous sub-cutaneous nodules and plaques. Histopathologically, subcutaneous fat necrosis with granu-lomatous panniculitis and needle-shaped clefts in the cytoplasm of foamy and multinucleated histiocytic giant cells are diagnostic.

We report an uncomplicated case of subcutaneous fat necrosis in a 21-day-old, normally delivered male infant, which developed on the fourth day of life and spontaneously regressed in 4 months.
