  16 October 2006

  basal-like mammary carcinoma; basal-like breast cancer
  Definition: Basal-like tumors are a subtype of breast cancer which express genes that are characteristic of basal epithelial cells, such as the basal cytokeratins, and are associated with poor relapse-free and overall survival.
  Basal like breast carcinoma is poorly differentiated, medullary like histologically (but with a poor prognosis) triple negative (-ER, - PR, - Her2), positive for vimentin, CK5/6, and may stain for p63 and S100. (...)

• mammary hamartoma
  29 May 2006

  Microscopy
  Hamartoma of breast consisting of dilated ducts and fibrous stroma.
  A partial capsule is evident.
  The fibrous stroma can have slit-like spaces without endothelial cells, so called "pseudoangioma".
  Differential diagnosis: mammary biphasic lesions
  adenomyoepithelioma
  mammary fibroadenomas
  mammary juvenile fibroadenoma
  mammary hamartoma
  metaplastic mammary carcinoma
  phyllodes tumor
  pleomorphic adenoma

  Definition : The mammary fibroadenoma is a benign mammary biphasic tumor with epithelial and stromal components.
  It is a benign breast lesion that result from hyperplasia of the normal lobules.
  It is a circumscribed, often large, breast mass usually occuring in adolescent females with stromal and (...)
