Solitary fibrous tumor arising in the fallopian tube

Abdominal mass mimicking a leiomyoma: Malignant uterine solitary fibrous tumor

“…Initially identified as a distinct pleural lesion, SFTs are tumors of ubiquitous location and they were described at various extrapleural sites. In the female tract, SFT is extremely uncommon (Berzal-Cantalejo et al, 2005). Usually, patients range from 20 to 70 years.…”

“…Myxoid liposarcoma is separable from myxoid SFT by the presence of lipoblasts, an arborizing capillary vasculature and pools of stromal mucine. Nerve sheath tumors and The biological behavior of extrapleural SFT has been regarded as unpredictable (Morimitsu et al, 2000;Vallat-Decouvelare et al, 1998;Berzal-Cantalejo et al, 2005;De Saint Aubain Somerhausen et al, 1999;Lau et al, 2009;Hasegawa et al, 1999). Some tumors with atypical histological features (such as, nuclear atypia, infiltrative margins, high cellularity, increased mytotic rate and foci of hemorrhage and necrosis) did not behave aggressively and other tumors without any atypical histologic features developed local recurrence or distant metastasis (Morimitsu et al, 2000;De Saint Aubain Somerhausen et al, 1999;Hasegawa et al, 1999).…”

“…Formerly believed to be restricted to the pleura, solitary fibrous tumors (SFTs) have been increasingly recognized in extrapulmonary sites (Morimitsu et al, 2000;Vallat-Decouvelare et al, 1998). In the female genital tract they are extremely rare and there are only scarce reports in the literature (Berzal-Cantalejo et al, 2005). Typical histologic features of SFTs include haphazardly arranged spindle cells, alternating hypocellular and hypercellular areas, collagenous stroma, and thin-walled branching blood vessels (Morimitsu et al, 2000;Vallat-Decouvelare et al, 1998;Berzal-Cantalejo et al, 2005).…”

Although myxoid change is not an uncommon finding in SFTs, those with a prominent myxoid stroma are quite rare (De Saint Aubain Somerhausen et al, 1999;Lau et al, 2009).…”

Solitary fibrous tumour of round ligament mimicking a leiomyoma

“…Many extrapleural manifestations have been described, including the uterus and fallopian tube (Berzal-Cantalejo et al 2005;Wakami et al 2005). No literature however, has documented involvement of the round ligament.…”
