Introduction: Nephrogenic adenoma (NA) is a rare benign tumor of urinary tract and is found most commonly in the bladder. This case is about the unusual urethral mass which was mimicking like urethral carcinoma and came out to be NA on histopathology.
Case Report: A 47-year-old male presented with two months history of obstructive urinary symptoms and intermittent per urethral bleed. Ultrasound revealed mild prostatomegaly with significant post-void residual urine and urethral stricture pattern on uroflowmetry. Retrograde urethrogram confirmed urethral stricture with filling defect proximal to urethral stricture. Magnetic resonance imaging (MRI) pelvis reported it as altered intensity polypoidal lesion in bulbar urethra suggestive of urethral malignancy. Optical internal urethrotomy for the urethral stricture and transurethral resection of mass was done. Histopathology and immunohistochemistry confirmed it as NA.
Conclusion: Nephrogenic adenoma should be considered in differential diagnosis of nested urothelial carcinoma and urethral adenocarcinoma.
Keywords: Immunohistochemistry, Nephrogenic adenoma, Urethral carcinoma, Urethral stricture
