Explain of Pulmonary Pathology

91.Lung, metastatic carcinoma, microscopic

A nest of metastatic infiltrating ductal carcinoma from breast is seen in a dilated lymphatic channel in the lung. Carcinomas often metastasize via lymphatics. Prostatic adenocarcinoma is famous for metastasizing to the lungs in a "lymphangitic" pattern in which streaks of tumor appear between lung lobules and beneath the pleura in lymphatic spaces.
