註釋Abstract: Mucinous cystadenoma is a benign tumor commonly found in the pancreas, the ovaries or the appendix. Only very few cases of these tumors originating from the lungs have been reported worldwide, with even less cases describing malignant transformation. We present the case of a 58-year-old woman with a history of recurrent pulmonary infections who underwent left upper lobectomy for lung abscess and was initially diagnosed with pulmonary mucinous cystadenoma (PMCA). Upon thorough immunohistochemical workup, especially due to carcinoembryonic antigen (CEA) positivity, intramucinous singlet cells were eventually diagnostic for invasive carcinoma, in this case a mucinous cystadenocarcinoma arising from a PCMA. PMCA is a rare benign tumor whose potential for malignant transformation has not yet been fully understood. Due to the low number of cases further studies are needed to evaluate if there is a benefit of complete oncologic resection, provided the general condition of the patient allows it. A review of the currently available literature serves to better understand the clinical, radiological and histological features of this rare tumor
