Abstract:
A malignant tumour of the rat pancreas with features of both acinar and endocrine cells is presented. This consisted of a continuous cytoplasmic mass with numerous dispersed nuclei and branches protruding from its borders invading the surrounding exocrine tissue. The most prominent characteristic of the tumour was the co-existence of zymogen and endocrine secretory granules and cytoplasmic organelles typical of both acinar and islet cells. Some hypotheses are put forward concerning the origin of the tumour and its vasculature.
