Adenocarcinoid of appendix presenting as bilateral ovarian tumors. A case report with histochemical and ultrastructural studies.
A 62-year-old female presented with bilateral ovarian tumors. These proved to be metastatic from a primary appendiceal lesion which showed histochemical and ultrastructural evidence of differentiation along two cell lines with features of both carcinoid and mucinous tumor. This case illustrates the malignant potential of so-called mucinous carcinoid or adenocarcinoid of the appendix.
