case_images: A 68-year-old man with elevated prostate-specific antigen (PSA). The lesions (arrows) showed a high signal on T1-weighted images (A) and a low signal on T2-weighted images (B).

case_images: A 68-year-old man with elevated prostate-specific antigen (PSA). (A-D) Ultrasound revealed a morphologically abnormal prostate (A) and a hypoechoic nodule (arrows) at 3-8 o'clock in the peripheral zone (B), with an abundant blood flow signal in it (C). (D) A transperineal prostate biopsy was performed under ultrasound guidance.

case_images: Prostatic malakoplakia misdiagnosed as prostate cancer. A large number of Michaelis-Gutmann bodies (arrows) were seen in the interstitium. (A) Histochemical staining showed large intracellular deposits of calcium (B) and iron (C).
