A Rare Presentation of a Giant Pararectal Implantation Dermoid Cyst Following a Blast Injury: A Case Report.

Blast injuries to the perineum have become prevalent on battlefields with the use of improvized explosive devices. Such injuries were commonly encountered during the height of the internal conflict in Sri Lanka from 2007 to 2009. These were associated with unique complications as well as challenges in their management. We present a case of a complex perineal injury which was initially reconstructed with a Gracilis neosphincter, presenting a decade later as a giant implantation dermoid incorporating the rectum.
