RESUMO
Congenital cystic adenomatoid malformations are lung anomalies usually detected prenatally or in newborns and infants. Type 1 congenital cystic adenomatoid malformations appears as a multicystic lesion, with cysts up to 2 cm in diameter, or as a single large cyst. In the latter case, when detected in adults, the preoperative diagnosis is challenging because congenital cystic adenomatoid malformations can be confused with other more common lesions. We describe two cases of uniloculated type 1 congenital cystic adenomatoid malformation in adults. In both cases, the preoperative clinical diagnosis was missed and the patients were surgically treated with lung-sparing cyst resections.

We report a rare case of malignant pleural mesothelioma presenting clinically with pneumothorax and histologically with an exclusive intrapulmonary lepidic growth. Neither intrathoracic nodules nor pleural thickening were found. The patient subsequently experienced acute abdominal pain with peritonitis and intestinal occlusion by peritoneal mesothelioma. The morphologic clues leading to the correct diagnosis of mesothelioma with prominent intrapulmonary growth are briefly discussed.
