Concomitant mucinous tumors of appendix and ovary. Result of a neoplastic field change?

Abstract

Mucinous tumors of the appendix and ovary are known to occur together in association with pseudomyxoma peritonei. It has been postulated that this association may be attributable to the development of independent tumors or to metastasis from one site to another. This article reports two patients with concomitant mucinous ovarian and appendiceal tumors in the absence of pseudomyxoma peritonei. The evidence suggests that these tumors are independent primary neoplasms that develop as a result of neoplastic field change that affects colonic-type epithelium.
