Epithelial mucosubstances and argyrophil cells in Brenner tumours.
Brenner tumours of various degree of malignancy were investigated by histochemical methods. The cells lining the cystic cavities in the benign Brenner tumours contained various amounts of PAS-positive, diastase resistant secretory material mixed with small amounts of sulpho- and carboxymucin. The borderline and malignant tumours contained more acidic mucins than the benign tumours. All tumours contained glycogen. Argyrophil and argentaffin cells have not earlier been detected in the Brenner tumours but in this study they were detected in twelve of the 18 Brenner tumours. These cells were not proliferating and therefore Brenner tumour should not be included in the group of APUDomas.
