Pulmonary embolization of a precipitate containing calcium phosphate resulted in the death of two patients. The pH of the amino acid component, transient elevation of calcium and phosphorus concentrations during mixing, and the lack of agitation during automated preparation of the formulation were identified as the etiologic factors producing the fatal precipitate.

Eosinophillic panniculitis is a poorly defined entity with variable clinical features. We report a case of rapidly enlarging, asymptomatic subcutaneous scalp nodules in a 6-year-old black boy with atopic dermatitis. The nodules resolved spontaneously over two to three days. Biopsy specimens were remarkable for eosinophilic panniculitis without evidence of epidermal change or vasculitis. We believe that this is the youngest reported patient with this disorder.
