title: Primary leiomyosarcoma of the prostate with lung metastasis: report of a case diagnosed by fine-needle aspiration cytology.
abstract: Prostate leiomyosarcoma is an extremely rare and highly aggressive neoplasm that accounts for less than 0.1% of primary prostate malignancies. Herein, we present a patient with primary leiomyosarcoma of the prostate with lung metastasis diagnosed primarily on fine-needle aspiration cytology. Characteristic cytological features such as small fascicles of spindle cells with blunt-ended nuclei, positivity for desmin and smooth muscle actin along with the radiological features are helpful in the correct diagnosis.
