    How to diagnose Disseminated peritoneal leiomyomatosis ?
    ### Response:
    How is disseminated peritoneal leiomyomatosis (DPL) diagnosed? An ultrasound may reveal the presence of nodules (lumps) which may indicate disseminated peritoneal leiomyomatosis (DPL). However, DPL can only be confirmed by a biopsy of the nodule. The nodules should contain smooth muscle cells with no atypia (no abnormal structure) or necrosis (dead cells).
