How long will I be blue? Prolonged skin staining following sentinel lymph node biopsy using intradermal patent blue dye.

Background: Blue dye used for sentinel lymph node biopsy (SLNB) in breast cancer patients may cause prolonged skin discoloration at the site of injection. The aim of this study was to assess the duration of such skin discoloration.

Patients And Methods: 236 consecutive patients who had undergone breast conserving surgery and SLNB for breast cancer were reviewed prospectively from January 2007 to December 2009.

Breast microcalcification: diagnostic value of calcified and non-calcified cores on specimen radiographs.

To determine if the specimen without calcification, as depicted on specimen radiography, made any contribution to the final histopathological diagnosis in comparison to the specimen with calcification. The records of 1312 stereotactic vacuum-assisted biopsies for breast microcalcifications between February 2000 and December 2010 were reviewed retrospectively. Following specimen x-ray the biopsy tissues with and without microcalcifications were sent in two separate pots (pot 1 and pot 2 respectively).
