Exfoliative cytology of angiosarcoma of the pulmonary artery.
A case of primary angiosarcoma arising from the pulmonary artery of the left upper lobe is documented. Clinically, the tumor presented as an asymptomatic solitary lung mass. Exfoliated tumor cells in bronchial washing material occurred singly, in irregular clusters and in sheets with focal glandlike arrangement. They showed ill-defined, pale cytoplasm and fairly regular round-to-oval nuclei with irregular chromatin patterns.
