Abstract

Aims: To assess the frequency and cause of incidental (non-metastatic) lymph node pathology discovered before or at radical prostatectomy.

Methods: Eight hundred and fifty four consecutive lymphadenectomies received between 1988 and 2001 were reviewed. All had been processed and stained routinely. Additional techniques, indicated by morphology, were then performed.

Results: Incidental pathology was found in 15 cases: florid sinus histiocytosis following prosthetic joint replacement (eight), non-caseating granulomas (three), small lymphocytic cell lymphoma (two), follicular lymphoma (one), and foreign body reaction (one). Incidental pathology was present in 1.8% of 854 patients who underwent pelvic lymphadenectomy during radical prostatectomy.

Conclusion: Awareness of possible non-metastatic lymph node pathology aids histological diagnosis and may be clinically relevant.

  • pelvic lymph nodes
  • lymphadenectomy
  • radical prostatectomy
  • incidental findings
  • EDX, dispersive x ray microanalysis
  • H&E, haematoxylin and eosin
