  • Title: Benign glandular inclusion in obturator lymph node of a man treated for prostate carcinoma.
    Author: Moreira Leite KR, Sarkis AS, Camara-Lopes LH.
    Journal: Pathol Int; 2007 Jul; 57(7):454-7. PubMed ID: 17587246.
    Abstract:
    Benign glandular inclusions in lymph nodes are extremely rare in men. Their identification is essential because it changes dramatically the prognosis and therapy of neoplasms. Described herein is the first case of benign glandular inclusion in an obturator lymph node dissected during a radical prostatectomy for treatment of prostate adenocarcinoma. A 60-year-old man underwent radical prostatectomy and obturator-hypogastric lymph node dissection for treatment of prostate adenocarcinoma. Benign glandular inclusion was found in microscopic examination. The lesion was characterized by two glandular spaces lined by a single, cuboid, benign epithelium localized in the sinus of one of four dissected lymph nodes. Immunohistochemistry showed mesothelial differentiation. Pathologists should be aware of benign glandular inclusion in obturator lymph nodes dissected during a radical prostatectomy for treatment of prostate cancer in order to avoid the incorrect diagnosis of metastatic disease.
