title: Cutaneous Metastasis from Breast Carcinoma: a brief report of a rare variant and proposed morphological classification.
abstract: BACKGROUND
  Breast carcinoma is the second commonest cancer in women after non-melanoma skin cancers and, excluding melanoma, the most common tumor to metastasize to the skin in women. Cutaneous metastasis from breast cancer has varied presentations but there is no well-established classification which includes them all.
  
  
  CONCLUSIONS
  We report a 69 year-old lady with advanced primary ductal carcinoma of right breast (cT4cN1cM0) who presented five months after radical mastectomy with very extensive cutaneous metastases in absence of distant spread. Skin involvement was in the form of nodules and purpuric papulo-vesicles on a background of erythema which clinically mimicked lymphatic malformation. We also propose a morphological classification of the cutaneous metastasis from breast cancer.
  
  
  BACKGROUND
  Breast Carcinoma, Cutaneous metastasis, lymphatic malformation.
