Lung metastases of low grade phyllodes tumor of the prostate: Histopathologic confirmation

Abstract

OBJECTIVE: Phyllodes tumor of the prostate is a rare neoplasm. We report the clinical, histopatho-logical, and immunohistochemical features of a low grade phyllodes tumor of the prostate with lung metastases. METHODS: A 68-year-old man presented acute urinary obstruction. Suprapubic prostatectomy was performed, and one month later he developed acute urinary obstruction, shortness of breath and cough. RESULTS: Microscopically, the prostatic tumor showed elongated ducts and cellular stroma. Lung biopsy was composed of stromal cells with enlarged, hyperchromatic nuclei. CONCLUSION: This case represents a typical low grade prostatic phyllodes tumor to lung. Grading of these neoplasm is not always of value to predict patient prognosis.
