Abstract

The authors describe two mucinous ovarian tumors that were hormonally active due to Sertoli-Leydig elements within the septal stroma. Carcinoid was also present in each case. The mesenchymal stromal cells within the septa of the mucinous tumors have undergone neoplastic proliferation with the Sertoli and Leydig differentiations, leading to the formation of arrhenoblastoma. The carcinoid component of these tumors is thought to have originated from argentaffin cells of the "intestinal" mucinous epithelium.

Abstract

Electron microscopic study of borderline serous and mucinous ovarian tumours was carried out and revealed marked heterogeneity of both types of these tumours. On the basis of the remote results of surgical treatment of the patients the most dangerous subtype from the point of view of its malignancy, the so-called proliferating, tumour with atypical epithelium, was established.
