Retrorectal and presacral tumors a clinicopathologic study

ABSTRACT

Neoplasms in the retrorectal or presacral area are uncommon. In this work we aimed at studying the cases of retrorectal or presacral tumors admitted to our institute in the last four years by H and E stain, immunostain and electron microscopy with review of the literature. Twenty nine patients are included in this study, having variable lesions comprising 10 congenital, 2 neurogenic, 1 osseous, 4 soft tissue tumors, 5 multiple myeloma and 7 metastatic lesions. Difficult cases were studied by immunostain and / or electron microscopy. Both techniques proved to be highly specific in diagnosing equivocal cases and determining the cell of origin
