Sporadic Intra-Abdominal Desmoid : A Rare Presentation as a Hepatic Mass

Abstract EN

We report an unusual presentation of a sporadic intra-abdominal desmoid tumour, possibly arising from the diaphragm, masquerading as a hepatic mass in a young female without any history of surgery or trauma.

Histopathology ruled out a hepatic origin of the tumour as was inferred from pre- and intraoperative evaluation.

Immunohistochemistry showed positivity of lesional fibroblastic cells for β-catenin and negativity for CD34, CD117, EMA, SMA, desmin, vimentin, cytokeratin, and ALK1 thereby confirming the diagnosis of a desmoid tumour.

There exist only a few reports in the literature on desmoids related to the diaphragm, but only one on a diaphragmatic desmoid that is possibly primary.
