Cystic fibrosis in a black woman.

This article reports a case of a 22-year-old unmarried black woman with 
cystic fibrosis. There is only one report in the literature of 
cystic fibrosis in a black person over 20 years old. Due 
in part to the deficiency of pancreatic exocrine secretions and the 
production of a copious amount of highly viscous mucus by gastrointestinal 
glands, patients with cystic fibrosis are prone to recurrent intestinal obstruction, 
intussusception, and volvulus, as well as abdominal pain and masses. Shwachman 
and Holsclaw firmly state that the diagnosis of cystic fibrosis may 
be made on the histologic appearance of the appendix.
