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

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 of exacerbation of symptoms and consequently, had to undergo open prostatectomy. based on histopathological and immunohistochemical (ihc) assessment, a diagnosis of sft of the prostate was rendered. additionally, we have discussed the histological mimics of sft and the diagnostic and prognostic importance of ihc while evaluating such lesions.
