079 – Edema in “cobbled street”

“Stoned edema”. Typical aspect in the left area of the image, where the mucosa, although retaining its homogeneous coloration, is presented as an irregular street on its surface and reminds the stoned of the pavements. It leads here to the anterior segmental of the right upper lobe (RB3) and must be differentiated from the “regular” edema that is smooth, and in which its biopsy does not usually clarify the origin. It is common to find neoplastic cells in samples of stoned edema, since the etiology of the rule is infiltration of the mucosa by bronchogenic carcinoma.
