Postrectal neoplasms and cysts are uncommon, arising from or involving structures within or near the extensive postrectal space. A 25-year review in Oregon identified 63 such cases, highlighting their rarity.

Area of Science:

Anatomy
Oncology
Pathology

Background:

The postrectal space is anatomically related to the sacrum and coccyx.
Neoplasms and cysts can originate from or involve structures within this space.

Purpose of the Study:

To review the incidence and characteristics of postrectal neoplasms and cysts.
To understand the epidemiology of these rare conditions.

Main Methods:

A retrospective review of patient cases from hospitals in the Portland, Oregon area.
Data collected over a 25-year period (1950-1975).

Main Results:

A total of 63 cases of postrectal tumors and cysts were reported.
The study population in Oregon was 379,000 in 1970.

Conclusions:

Postrectal neoplasms and cysts are uncommon conditions.
These findings are based on a review of cases in a specific geographic region over a defined period.
