case_images: Pathology. Prostate biopsy (a), (c), (d) and transurethral resection (b). (a) Poorly differentiated adenocarcinoma with GS 5 + 5 (hematoxylin and eosin staining, magnification 10x). (b) Adenocarcinoma with GS 5 + 5. Findings similar to prostate biopsy (hematoxylin and eosin staining, magnification 10x). (c) Prostrate-specific antigen staining is slightly positive (magnification 10x). (d) NKX3.1 staining is diffusely positive (magnification 10x).

case_images: Prostate biopsy and transurethral resection were performed to control hematuria. Pathological examination revealed adenocarcinoma with a GS of 5 + 5, and transurethral resection of the bladder tumor was performed (Fig. 3).
case_images: Bone scintigraphy. Metastases to the left acetabulum (red arrow) and right pubic bone (blue arrow). RI accumulation in the Th11 vertebral body was diagnosed as a hemangioma based on CT findings.
