[CA-125--a tumor marker of lymphangioleiomyomatosis of diagnostic and prognostic importance?].

Lymphangioleiomyomatosis is a rare tumour of the lymphatic system, affecting mostly women of childbearing age. Due to its rare occurrence, diagnosis is mostly made after thorough examination therefore time for an early treatment is lost. Diagnostically important are, on the one hand, the histological findings with smooth muscle cells invading the lymphatic system, and on the other hand thin-walled cysts in CT scanning of the lung. CA-125 seems to be a suitable screening parameter for LAM, which may be additionally of prognostic value. Sensitivity and specificity of CA-125 require further observation.
