Calcified subcutaneous fat necrosis in infancy

A case of subcutaneous fat necrosis with extensive soft tissue calcification in a newborn infant is described. with marked regression of the lesions over a 15 month period of follow up. This condition is of unknown etiology and is characterized by focal or widespread areas of raised, firm, subcutaneous tissue secondary to necrosis of fat cells and the accompanying cellular reaction. Dystrophic calcification may occur with or without coincident hypercalcemia. Spontaneous regression occurs over a period of weeks to months. No specific treatment is indicated in the absence of complications.
