    Inflammatory Myofibroblastic Tumor of the Prostate
    (2016) Kocer, Nazim Emrah; Bal, Nebil; Gul, Umit; Aydin, Hakan
    Inflammatory myofibroblastic tumors (IMT) of the prostate are very rare lesions that may mimic sarcomas and spindle carcinomas both clinically and histopathologically. The case presented here is a 63-year-old patient, with normal prostate specific antigen levels and a chronic history of complaints, who underwent to suprapubic prostatectomy due to the infravesical obstruction symptoms that are resistant to medical therapy. Histopathological examination of the excision material revealed a well demarcated spindle cell lesion with focal nuclear polymorphism, hyperchromasia, mononuclear inflammatory infiltration and myxoid areas. Mitosis was rare. Immunohistochemically smooth muscle actin and vimentin were positive, anaplastic lymphoma kinase-1 was focal positive, S-100 and pancytokeratin were negative. The lesion was diagnosed as an inflammatory pseudotumor. Differential diagnosis of the IMT from malignant spindle cell tumors of the prostate is crucial to prevent overtreatment.
