Click, smooth muscle tumors of uncertain malignant potential, WHO: uterine smooth muscle tumor that cannot be histologically diagnosed as unequivocally benign or malignant, Classify as none / mild or moderate / severe, based on nuclear pleomorphism, nuclear size, nuclear membrane irregularities, chromatin density and nucleoli size/prominence, No / mild atypia: uniform nuclei that may be enlarged, but with smooth nuclear contours, evenly distributed chromatin; minimal variation in nuclear size and shape, small nucleoli, Moderate / severe should be detectable at low power, Moderate atypia: large, plump and irregular nuclei with coarse chromatin; if 1 - 2 enlarged abnormal mitotic figures, call moderate atypia, Severe atypia: obvious pleomorphism, numerous cells with enlarged bizarre nuclei with dense chromatin; frequent giant cells, often multinucleated, enlarged and sometimes atypical nucleoli, Hairy extensions of chromatin must be present, extending from a central clot-like dense mass of chromosomes; hairy extensions from an empty center favor a non mitosis, Count 4 sets of 10 fields in area of highest mitotic activity, and use the highest count, Must rule out lymphocytes, mast cells, stripped nuclei, degenerated cells and precipitated hematoxylin, Presence or absence is powerful predictor of outcome for patients with uterine smooth muscle tumors, Must distinguish coagulative tumor cell necrosis and hyalinizing necrosis, Coagulative tumor cell necrosis: abrupt transition between necrotic cells and preserved cells; ghost outlines of nuclei of necrotic cells are often seen in necrotic area, but inflammatory cells are uncommon; common in clinically malignant smooth muscle tumors - DON'T IGNORE, Hyalinizing necrosis: zone of hyalinized collagen between dead cells and preserved cells, reminiscent of infarcted region organized by granulation tissue; eosinophilic collagen matrix common; if dead nuclei present, nuclei are uniform and chromatin is often faint, compared to nuclear hyperchromasia and pleomorphism in tumor cell necrosis; common in leiomyomas, Necrosis secondary to ulceration in submucous leiomyomas features acute inflammatory cells and a peripheral reparative process, whereas ghost outlines of nuclei are usually inconspicuous or absent, No / mild atypia, no tumor cell necrosis → leiomyoma, Moderate / severe atypia, no tumor cell necrosis → atypical leiomyoma if < 10 mitotic figures/HPF or leiomyosarcoma if 10+ MF/10 HPF, Moderate / severe atypia and tumor cell necrosis → leiomyosarcoma (mitotic figures don’t matter), Suggested to consider as tumor of low malignant potential because may recur (, Conservative because low likelihood of leiomyosarcomatous transformation (. , in diagnostic Pathology, follow-up and recurrence rates stump of the Head and Neck ( Second Edition,!, 2 hours after cutting abbreviated stump Guidelines Page | 1 Specimen:...
