Pathology Image Detail

Caption

Fibroadenoma with atypia: this photomicrograph illustrates a portion of the neoplasm composed of small glands with atypia. Neoplastic cells are large and most of them contain a large lipid vacuole. The nuclei are large, too, and there is moderate anisokaryosis. There is a moderate granulocytic (eosinophilic?; predominantly), lymphocytic and plasmacytic inflammation of the stroma. Small clusters of cells seem to be engaged in the early stages of cornificatin (arrowhead).
