BREAST - Carcinoma

A portion of breast showing surgical incision, healing, running upwards from an umbilicated, partly-ulcerated extension of tumour into the nipple. On the posterior surface the main tumour mass, some 3 cm. in diameter, can be seen with a further tumour 2 cm in diameter a little distance away. In the main tumour mass stellate extension of the tumour into the surrounding fat can be seen. The histology of the lesions is that of a diffuse infiltrating carcinoma; there were, in fact, four distinct tumour nodules in the specimen.
