Patent blue and air as an alternative for resection of nonpalpable breast lesions: a case series.

Context And Objective: Use of mammography for breast cancer screening has resulted in a significantly increased number of patients with nonpalpable radiological findings that need histopathological study for better management. The present study evaluated an alternative to excision of nonpalpable breast lesions, using injection of patent blue (CAS 3536-49-0) dye and air.

Design And Setting: Cohort study of 64 consecutive patients at a private clinic in the city of Teresina (Piauí), between January 2009 and December 2010.
