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.
