False-Negative Histopathologic Diagnosis of Prostatic Adenocarcinoma.

CONCLUSIONS.—: Knowledge of the reasons for histopathologic false-negative diagnosis of adenocarcinoma of the prostate is an important component in the diagnostic assessment of prostate tissue sections. Diagnostic awareness of the histomorphologic presentations of small (minimal) adenocarcinoma; deceptively benign appearing variants including atrophic, foamy gland, microcystic, and pseudohyperplastic variants; single cell carcinoma; and treatment effects is critical for establishment of a definitive diagnosis of adenocarcinoma and the prevention of false-negative diagnoses of prostate cancer.

In conclusion, NKX3.1 shows routine expression in Sertoli cells and P501S shows routine expression in Leydig cells and rete testis epithelium. In addition, these markers can be positive in sex cord-stromal tumors and rete testis adenocarcinoma.
