case_images: PSA increased up to 3.47 ng/mL. PSMA PET scan was obtained and revealed suspicious uptake in the left side of the abdominal wall within a 7 mm soft tissue nodule abutting the left rectus abdominis muscle (Figure 1). One abdominal wall lymph node (LN) was found to be positive for prostatic adenocarcinoma (Figures 1(a) and 1(b)).
case_images: Microscopic examination of abdominal wall lymph node with H&E staining (a), with 10x magnification (b) showing that LN is extensively involved by neoplastic glands. Positive nuclear stain for NKX3 (c) and cytoplasmic stain for PSA (d) confirming prostate origin of the tumor.
