Pulmonary alveolar proteinosis coexisting with homozygous hemoglobin E

Pulmonary alveolar proteinosis (PAP) is an uncommon lung disorder of obscure and possibly diverse causes characterized by abnormal accumulation of lipoproteinaceous surfactant material in alveoli. The prevalence of acquired PAP has been estimated to be 0.37 per 100,000 populations. We present a case of PAP coexisting in homozygous hemoglobin (Hb) E....
