肺硅结节

图示:硅结节

长期吸入二氧化硅致肺纤维化,如图红节中央可见高密度粉红色胶原。

Sometimes the inflammatory reaction is mainly one of scarring, as seen here with a silicotic nodule of the lung. The inhaled silica persists indefinitely and produces an inflammatory reaction that is marked by prominent fibrosis. Dense pink collagen is seen in the center of the nodule.
