Two Cases of Metastatic Leiomyosarcoma Diagnosed by Fine Needle Aspiration / 대한세포병리학회지

Cytologic finding of 2 cases of metastatic leiomyosarcoma diagnosed by fine needle aspirtion cytology are reported. Case 1 is pleomorphic leiomyosarcoma which had metastsized to the liver from the stomach of a 54-year-old male patient. The cytologic features showed highly cellular aspirates with nuclear pleomorphism and interlacing patern. Case 2 is low grade leiomyowsarcoma that occurred in the uterus of a 43-year female patient and metastsized to both lungs. The aspirates were less cellular than that of case 1, and showed spindle cells with minimal pleomorphism, but cell block revealed interlacing patterns of smooth muscle cells with occasional mitosis.
