ABSTRACT
Diffuse pulmonary meningotheliomatosis (DPM) is an extremely rare condition. We herein report a unique case of DPM in a 54-year-old woman with a previous history of hepatocellular carcinoma. A chest computed tomography showed diffuse bilateral nodular infiltration, suggesting miliary spread of metastatic hepatocellular carcinoma. The patient underwent a video-assisted thoracoscopic surgery for diagnostic purposes. The cut surface of the lung specimen showed multiple dispersed small nodules, consisting of variably sized nests or whorls of bland epithelioid cells often along the walls of alveolar septa or in a perivascular network within the alveolar interstitium. The tumor cells showed immunoreactivity for epithelial membrane antigen, vimentin, and progesterone receptor. DPM should be included in the differential diagnosis of diffuse multiple small nodules or a reticular pattern in the radiologic studies.
