Prolonged survival in a patient with recurrent pulmonary metastases secondary to mucinous cystadenocarcinoma of the appendix with pseudomyxomatous peritonei.

Abstract

We report a 65-year-old man presenting with recurrent pulmonary metastases 20 years after an appendectomy for mucinous cystadenocarcinoma with pseudomyxomatous peritonei. He underwent bilateral staged metastatectomies for metastases 7 years after the diagnosis and further metastasectomy after a recent recurrence. This is a rare case of recurrent pulmonary metastatic mucinous cystadenocarcinoma, and despite poor prognosis and nondefinitive initial treatment, this patient remains alive and well 20 years later.
