disseminated peritoneal adenomucinosis

A term relatively recent inception meant to partially replace the antiquated, nonspecific and confusing term pseudomyxoma peritonei, which has been applied to mucinous ascites arising in both benign and malignant tumours of the appendix. Experts of the field now use the term disseminated peritoneal adenomucinosis for the benign end of the spectrum and peritoneal mucinous carcinomatosis for those with histologically malignant features (e.g., significant architectural and cytologic atypia) that have a less felicitous outcome.

DPAM is one of three conditions (along with peritoneal mucinous carcinomatosis and peritoneal mucinous carcinomatosis) that arise in pseudomyxoma peritonei, which must be distinguished therefrom because of DPAM’s better prognosis—5-year and 10-year survival rates of 75% and 68%, respectively.

Although we made the distinction between classic PP, with its low-grade cytologic and architectural features, and well-differentiated mucinous carcinoma, with high-grade cytology, increased cellularity, and mild architectural complexity, all of the peritoneal mucinous tumors in our study would be classified as mucinous carcinoma peritonei, low grade, using criteria proposed by Bradley et al (7) and as DPAM using criteria proposed by Ronnett et al (14) (Table 2).
Using these aggressive techniques, Sugarbaker et al33 report 5-year survival rates of 86% for patients with complete cytoreduction and adenomucinosis (DPAM), 50% survival rates for patients with hybrid or mucinous carcinoma and complete cytoreduction, and 20% survival rates for patients with incomplete cytoreduction.
