“…Previous experimental reports showed that submesothelial cells had the ability to differentiate into mesothelial cells [34,35]. Despite they are frequently regarded as pleural tumors, a variety of extrathoracic locations has been reported like the meninges and the soft tissues of the neck [8-10], pelvis [11,16,17] and retroperitoneum [14,15], liver [12,13], and the soft tissue [18-33]. Soft tissue SFTs still represent a rare entity with 46 cases described in the English literature, mainly from a histopathological point of view.…”

Solitary fibrous tumors of the soft tissues: imaging features with histopathologic correlations

PurposeTo describe the imaging features of soft tissue solitary fibrous tumors, with histopathological correlations and clinical outcome.Material and methodsTwenty-seven patients with histologically proven SFTs were retrospectively evaluated. Imaging studies included six radiographs, five U/S studies, eighteen CT scans, fourteen MRI exams, and one angiography.ResultsOn CT scans, two lesions were isodense and five were mildly hypodense compared to muscle while 11 lesions appeared heterogeneous-mixed of iso and hypodense areas. Heterogeneous enhancement was depicted in 13 lesions and four lesions enhanced homogeneously. Six lesions were partially calcified. On T1W MR images, seven lesions were isointense and one was slightly hyperintense relative to adjacent muscles while five lesions appeared heterogeneous-mixed of iso and hypointense areas. T2W images showed high SI in two cases and heterogeneous-mixed in seven cases. Enhancement was heterogeneous in six and homogeneous in four lesions. Patchy unenhanced areas (on CT and T1W MR images) along with patchy areas of low to markedly high SI on T2W images were depicted in 19 lesions. The enhanced portions correlated to areas of increased vascularity and cellularity. The four clinically more aggressive lesions could not be predicted on imaging.ConclusionTypical soft tissue SFTs are deep masses made of isodense and isointense areas relative to adjacent muscles mixed with hypodense and hypointense areas on unenhanced CT and MR T1W respectively. Variable enhancement patterns and mixed to high signal intensities on MRT2W are attributed to tumor’s cellularity, vascularity, collagen distribution and/or degeneration. Heterogeneity of SFTs affects imaging features on MRI and CT modalities. The biological behavior of soft tissue SFTs can not be predicted based solely either on histopathologic or imaging evaluation.

“…Despite they are seldom located in extrapleural soft tissue this tumor has been reported in a variety of extraserosal sites (Ramdial and Madaree 2001). By reviewing the literature following locations are described: lumbar extradural (Donnellan et al 2000), intrameningeal (Nawashiro et al 2000;Kawamura et al 2004), in cervical spine (Obara et al 2003;Bohinski et al 2004), in the deep soft tissue of the neck (Goh et al 2002;Bachmeyer et al 2004), in orbital space (Ahn et al 2001;O'Donovan et al 2002;Schellini et al 2003), in pelvic space (Ishikawa et al 2004), retroperitoneal (Nagasako et al 2004), vaginal (Akiyama et al 2000), in the thyroid gland (Parwani et al 2003;Babouk 2004), in mammary gland (Falconieri et al 2004), in prostate (Ishii et al 2004), in nasal mucosa (Munks 2003), in the liver (Neeff et al 2004), in renal pelvis (Yazaki et al 2001;Magro et al 2002), and in extremities (Akisue et al 2003). All of these tumors are diagnosed and categorized by histology and immunohistochemical patterns.…”

Solitary fibrous tumors (SFT) of extremities, especially the thighs are very rare. Despite SFTs are generally benign, well-circumscribed soft tissue tumors new cases should be presented and followed up carefully to monitor their biological behavior. In general for tumor classification a biopsy is state of the art. Histological including immunohistochemical patterns for SFTs are defined. MRI and ultrasound are not sufficient for differential diagnosis. Once property identified and defined by size and location, resection with intact tumor capsule may result in full recovery of the patient. Reviewing the literature there are no validated reasons for a wider resection. The current patient was a 41-year-old male. Four years after an arthroscopy of the left knee the patient has been suffering an ongoing swelling of the lateral thigh. Because MRI scan data suggested a synovial sarcoma a biopsy was performed. The tumor was classified as a benign SFT. The diagnosis based on histological findings and the presence of the positive immunohistochemical markers Vimentin, CD34, and CD99. The complete tumor resection with intact capsule was achieved in a final operation. Clinical and in MRI after 54-month outcome period there were no local recurrences.

“…There has been a renewed interest since its description in multiple organs and locations, including soft tissue [3]. In the abdominopelvic space, many cases have been reported in the retroperitoneum, the pelvis, the peritoneal space, the presacral space, and the liver [4–6]. …”

“…The latter is related to the quality of the surgical resection and rare malignancy of extrapleural location [3, 6, 8]. Authors agree on the absolute necessity to achieve a wide surgical excision as complete as possible to avoid local recurrence.…”

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.
