Solitary Fibrous Tumor of the Prostate: A Diagnostic Challenge: A Case Report

Abstract: Solitary fibrous tumor (SFT) of prostate is an unusual type of mesenchymal neoplasm that can elicit a benign or malignant phenotype. It represents a diagnostic challenge as it can simulate poorly differentiated adenocarcinoma and various mesenchymal neoplasms of prostate. We report a case of prostate SFT in a 54-year-old patient, which was clinically misdiagnosed as nodular hyperplasia of prostate with cystitis. However, on follow-up, he was not relieved by the designated treatment. Furthermore, he complained … Show more

“…Su etiología y su patogenia son desconocidas, al igual que su célula original. Son tumores asintomáticos hasta que son lo suficientemente grandes como para comprimir los órganos vecinos vesicales y prostáticos, presentándose síntomas obstructivos como aumento de la frecuencia, retención y urgencia urinaria, junto con disuria y hematuria [8]. Los TFS se han descrito en otros órganos del sistema genitourinario, como la vejiga, las vesículas seminales, la pelvis renal y el cordón espermático [15].…”

“…y las pruebas moleculares. El examen histopatológico de biopsias muestra una neoplasia de células fusiformes dispuestas en un patrón desorganizado, acompañado de vasos hemangiopericíticos, los cuales tienden a tener una forma en astas de cuervo, sobre un estroma colagenizado acompañadas de áreas mixoides [18], y una tasa mitótica <4/10 HPF (del inglés, High Power Fields) [8].…”

“…Out of these, prostate SFTs are extremely rare, and approximately 25 such cases have been reported in the literature to date [6]. However, the diagnosis of mesenchymal neoplasms of the prostate is often difficult for pathologists because of their overlapping histomorphological and immunohistochemical (IHC) characteristics [7]. In fact, we previously encountered a patient with prostate SFT that was initially misdiagnosed as prostate cancer, based on histopathological examination of prostate biopsy specimen [8].…”
