title: Hyperplastic mesothelial cells in subpleural lymph nodes mimicking metastatic carcinoma.
abstract: We describe a patient with a history of poorly differentiated adenocarcinoma of the stomach in whom hyperplastic mesothelial cell inclusions were present in subpleural lymph nodes. The involved lymph nodes were embedded in a lipoma in the parietal pleura. The role of histochemistry and immunohistochemistry in the differentiation of these inclusions from metastatic carcinoma is discussed.
