Nishat Afroz, Jai Kumar Chaurasia, Nida Shamim

Abstract :

Calcifying fious tumor is a rare, benign mesenchymal tumor of children and young adults, usually occurring within the subcutaneous and deep soft tissues of the extremities, trunk, neck, inguinal and scrotal region. Its occurrence in peritoneum is rare. Here, we report a case of calcifying fious tumor, which incidentally presented as peritoneal mass at the right hepatic flexure of colon in a 30&amp;ndash;year&amp;ndash;old female who underwent laparotomy for ulcerative colitis and was operated for the same. The histopathological and immunohistochemical findings of the peritoneal mass were consistent with calcifying fious tumor, comprising of spindled fioblasts, abundant hyalinized collagen, several foci of dystrophic and psammomatous calcifications with focal lympho&amp;ndash;plasmacytic inflammation and positive vimentin and factor XIIIa immunoexpression.
