A case of subcutaneous fat necrosis of the newborn is described. Severe perinatal asphyxia preceded the appearance of the skin lesions. Premature rupture of membranes and the presence of foul-smelling meconium raised the possibility of infection by' anaerobes as an additional etiologic factor. The main hypotheses concerning the cause and pathogenesis of this condition are reviewed. The alarming clinical picture that stands in sharp contrast to the benign prognosis is stressed.
