Περίληψη:
Introduction. Solitary fibrous tumor is a rare type ofmesenchymal,
spindle-cell tumor reported mostly in the pleura. Retroperitoneal
occurrence is rare and histopathological diagnosis is challenging. Case
Presentation. A 55-year-old woman with nonspecific abdominal pain was
found to have a retroperitoneal/ pelvic mass adjacent to the upper
rectum. The patient underwent surgical resection in clear margins of
this pelvic tumor, entering the total mesenteric excision surgical
plane. Final histopathology revealed a solitary fibrous tumor and the
case is presented herein. Discussion. Solitary fibrous tumor in the
retroperitoneum is rarely found in the literature and to the best of our
knowledge less than a hundred cases are described so far.
Histopathological diagnosis is mostly based on a “patternless
pattern” on microscopic examination, which is a storiform arrangement
of spindle cells combined with a “hemangiopericytoma- like
appearance” and increased vascularity of the lesion. Surgery is the
mainstay of treatment and recurrence rates are generally low.
