BERNARDECO, Joana; FERREIRA, Pedro  e  BRANCO, Luís. Blue urticaria: a rare case of adverse reaction during sentinel lymph node biopsy for breast cancer. Acta Obstet Ginecol Port [online]. 2022, vol.16, n.2, pp.174-176.  Epub 30-Jun-2022. ISSN 1646-5830.

Sentinel lymph node (SLN) biopsy is used to access the axillary region for the presence of metastasis in breast cancer. SLN mapping is better accomplished by using a dual - modality tracing that includes a radioisotope and a blue dye. Although patent blue dye reaches high lymph node detection, it can be associated with allergic reactions. We describe a rare case of a blue urticaria that followed the injection of patent blue dye for SLN biopsy in a woman with breast cancer.
