title: Clinical syndromes associated with adult pneumococcal cellulitis.
abstract: Streptococcus pneumoniae is an uncommonly recognized etiology of cellulitis in adults. A review of the literature uncovered 30 cases of pneumococcal skin infection in adults. Typically, all patients with pneumococcal cellulitis had an underlying chronic illness, or were immunocompromised by drug or alcohol abuse. Pneumococcal cellulitis presents as two distinctive clinical syndromes: one with extremity involvement in individuals with diabetes and substance abuse; and a second involving the head, neck and upper torso in individuals with systemic lupus erythematosis, nephrotic syndrome and hematologic disorders. For each there are statistically significant associations between the location of pneumococcal cellulitis and underlying clinical disorders. In contrast to other common bacterial etiologies, pneumococcal cellulitis is frequently associated with blood stream invasion, tissue necrosis and suppurative complications. Patients often require surgical interventions and prolonged hospitalizations. A high degree of suspicion and early aggressive management is needed for those presenting with cellulitis characterized by bullae and violaceous color.
