However, the postoperative histopathological findings diagnosed the case as basal cell carcinoma with focal squamous differentiation ( Figures 1A, B ). Immunohistochemical staining was negative for P504s and NKX3.1 but positive for P63 ( Figure 1C ) and 34betaE12 ( Figure 1D ).
Prostate MRI. (A) Slightly longer T2; (B) Slightly longer T1; (C) Slightly high signal on DWI. MRI, magnetic resonance imaging; DWI, diffusion-weighted imaging.

Magnetic resonance imaging (MRI) of the prostate performed 40 days postoperatively showed a small lamellar long T2 ( Figure 2A ) and long T1 signal ( Figure 2B ) in the central lobe of the prostate with a slightly high signal on diffusion-weighted imaging (DWI) ( Figure 2C ).
