Laboratory Studies

Laboratory abnormalities associated with sclerema neonatorum correlate with the underlying disease process. Hypoglycemia, metabolic acidosis, respiratory alkalosis, hyperkalemia, hypocalcemia, and elevated blood urea are common, albeit nonspecific, findings. A complete sepsis workup should be initiated in all infants with sclerema neonatorum.

Histologic Findings

Despite the striking clinical presentation, histologic findings of sclerema neonatorum are subtle. The most consistent findings are edema, a thickening of the subcutaneous fibrous septa, and a radial array of fine, needlelike clefts in the fat cells. Autopsy studies have identified identical needle-shaped crystals in adipocytes of visceral fat in patients with sclerema neonatorum.[10] In the subcutaneous fat, inflammation is sparse and, when present, consists of lymphocytes, histiocytes, and multinucleated giant cells. In contrast to subcutaneous fat necrosis of the newborn, no granulomatous inflammation exists.
