ABSTRACT
Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of fibroblastic
type, which despite being located mainly in the pleura, has been observed in other
organs such as the prostate. On the other hand, solitary fibrous tumor of the prostate
is a rare neoplasm, slow growing, and of uncertain malignant potential, which is
generally composed of spindle cells of cytologically benign appearance, arranged in a disorganized architecture, mixed with collagen and small blood vessels. Establishing
its diagnosis has become more reproducible since the identification of
the NAB2-STAT6 gene fusion by molecular biology, leading to the overexpression
of STAT6 by immunohistochemistry, a very sensitive and specific marker for SFT.
We present a clinical report of a patient who consulted with symptoms of bladder
compression, in whom a mass was identified with the epicenter in the prostate
infiltrating into the bladder and reaching the rectal wall. Following histopathology
study, immunohistochemistry and molecular tests it was classified as a SFT of the
prostate, finally treated with radical cystoprostatectomy plus urinary shunt.
