Pulmonary cryptosporidiosis in patients with acquired immunodeficiency syndrome.

Several reports have showed Cryptosporidium species as a cause of intractable diarrhea and malabsorption in patients with acquired immunodeficiency syndrome (HIV). A case of chronic diarrhea in a drug addict woman associated with a symptomatic interstitial pulmonary infection due to Cryptosporidium parvum is described. This unusual C. parvum spread into the bronchial tree is underlined and a survey of the literature is made.
