A rare tumor of the mammary gland, built up of argyrophilic cells, with numerous metastases in the axillary lymph nodes is reported. Histochemical and electron-microscopic studied unequivocally demonstrated that this tumor belonged to the APUD system. The possible histogenesis of carcinoid tumor of the mammary gland is briefly discussed.

Hypertrophy and hyperplasia of islet tissue, established by morphometry, were proved in the pancreas of rats, treated chronically for a period of 2 months (with urbason-50 mg/kg of body mass). B-cells were granulated. Structures with myelin-like form of membranes were observed in some of them by electron microscope. Mixed islet B-acinar cells were established as well. These data were possibly a morphological expression of stimulating action of urbason on B-cells of Langerhans islets.
