Cytoenzymology of benign and malignant tumours of the corpus uteri. II. Lysosomal enzymes in relation to Golgi apparatus.

Cytological and cytochemical studies were carried out on benign and malignant tumours of the human corpus uteri. It was found that the Golgi complex was present in the form of granules of crescent-like structure. The elements of Golgi apparatus have two modes of distribution, the perinuclear and scattered types. The activity of acid phosphatase only which was located in the lysosomes had the same topographical configuration as Golgi apparatus. The degree of development of Golgi elements and the activity of both acid phosphatase and aryl sulphatase increased in malignant tumours as compared with benign tumours and normal tissues.
