title: Filariasis of the breast in a pregnant woman diagnosed by fine-needle aspiration cytology: a case report.
abstract: BACKGROUND
  Despite increased immigration to the United States from endemic areas, the diagnosis of microfilariasis in this country remains infrequent. This disease may occasionally present as a breast mass, in the absence of other clinical findings.
  
  
  METHODS
  We report an unusual case of Wuchereria bancrofti diagnosed in a pregnant woman by breast fine-needle aspiration (FNA) and discuss the clinical implications of filariasis in pregnancy.
  
  
  CONCLUSIONS
  FNA is safe and reliable in pregnancy. Infants of mothers with breast filariasis should be monitored.
