Intraperitoneal Solitary Fibrous Tumor

Abstract

Solitary fibrous tumors of the pelvis are rare. We report the case of a 32-years-old patient who presented with abdominopelvic mass. The imaging studies showed a right adnexal mass of more than 10 cm. Exploratory laparotomy revealed a 20 cm mass at the Douglas pouch which was adhered to the posterior wall of the uterus. Complete resection of the mass was performed. Histological analysis showed a spindle cell undifferentiated tumor whose morphological and immunohistochemical profile are consistent with solitary fibrous tumor. It is important to know that although these tumors are rare, their evolution can be pejorative. Therefore, long-term followup should be recommended.

Solitary fibrous tumor of the ovary

“…On MRI, in the T1‐weighted images, these tumors commonly have intermediate signal intensity, while on T2 images, they typically have low signal intensity. They show early and intense enhancement after contrast administration, by the virtue of which they can be differentiated from ovarian thecomas or fibromas, which show delayed enhancement . Although the tumor in our patient showed enhancement after contrast administration on MRI, the imaging features were nonspecific; hence, sex cord stromal tumor remained the working diagnosis.…”

Solitary fibrous tumour of the female genital tract: a clinicopathological analysis of 25 cases

“…Solitary fibrous tumour is an anatomically ubiquitous fibroblastic neoplasm that occurs infrequently in the gynaecological tract. Reported cases in the literature arose throughout the female genital tract, including the vulva (nine cases [7][8][9][10][11][12][13][14], vagina (five cases [15][16][17][18][19] ), cervix (five cases [20][21][22][23][24] ), uterus (five cases [25][26][27][28][29] ), ovary (two cases 30,31 ), fallopian tube (one case 32 ), and adnexal soft tissue (two cases 33,34 ). In keeping with the above, the vulva was the most common site (14/ 25; 56%) in our cohort.…”

“…Solitary fibrous tumour of the female genital tract has been the subject of only a few reports, possibly because of their under‐recognition, with only 29 cases having been described, as case discussions or small case series . The goal of this study was to augment the current understanding and raise awareness of this entity through a comprehensive analysis of 25 SFTs arising in the female genital tract.…”
