Desmoid tumor mimicking a strangulated hernia: About a case

Abstract

Desmoid tumors of the abdominal wall are very rare. Nonspecific clinical presentation may lead to
misdiagnosis. Radiological explorations are very contributive to help guide the diagnosis. Histological
and immunohistochemical examination are mandatory to confirm the diagnosis.
In our case, a rare desmoid tumor mimicked a strangulated hernia on a Pfannenstiel scar. The patient was
operated. Preoperative findings revealed a solid tumor developing from the muscles of the anterolateral
abdominal wall. The tumor was resected taking away a macroscopically healthy tissue. The peritoneum
was not invaded and a polypropylene mesh has been set. The postoperative follow-up was simple.
Anatomopathologicalexamination associated with immunohistochemical determination concluded to
a desmoid tumor.
