Abstract
Pregnancy complicated by histiocytosis X and preterm labor. Dungan JS, Ferguson II JE. The first reported case in which histiocytosis X was diagnosed during pregnancy is described. Worsening pulmonary symptoms required aggressive evaluation of the patient, including bronchoscopy and open lung biopsy. Preterm labor and diabetes insipidus also complicated this case, and rapid improvement in pulmonary symptomatology followed delivery.
