Mucinous cystadenocarcinoma arising from mucinous cystadenoma of the lung: case report and review of the literature

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.

“…4 Mucinous cystadenomas develop more frequently in the ovary and pancreas than in the lung, and they are known to be benign tumors with some malignant potential. In recent analyses of genetic alterations, frequent mutations of the KRAS gene have been identifi ed in these mucinous neoplasms from the ovary and pancreas.…”

Pulmonary mucinous cystadenoma (PMCA) is rare, with few reported cases. This tumor is histologically characterized by a benign proliferation of mucin-producing epithelial cells and bulky mucin inside the tumor. We present the case of a 71-year-old woman with increasing mass shadow on chest radiography who underwent tumor resection by video-assisted thoracic surgery. The tumor was diagnosed histologically as PMCA.

“…If they occur as cystic structures invading adjacent tissue, displaying apparent atypia and pseudostratification and containing a great amount of mucin, they are called mucinous cystadenocarcinoma (1). A limited number of cases are reported in the literature (2,3). They are benign tumors, and they are seen in the sixth and seventh decades of life in both genders (4).…”

A 58-year-old male patient was admitted to our clinic with complaints of productive cough and weight loss (6 kg) having begun with flu-like symptoms 15 days ago. His medical history included the use of acetylsalicylic acid after a cerebrovascular event from 9 years ago. The patient, who worked as a car mechanic, had 40 packs-year of smoking history. In the physical examination, his vital findings and oxygen saturation were within normal reference intervals, and no abnormality was observed, except limping in his right foot. Pulmonary function tests revealed mild obstructive dysfunction. The laboratory test value of C-reactive protein was 7.3, and the values of complete blood count and biochemistry were within normal intervals. The PPD test result was 10 mm.In the posteroanterior chest X-ray, an oval mass lesion, the long margin of which extended toward the hilus in the neighborhood of the aortic curve on the left, was observed. In the lateral radiography, it was detected that the mass was localized in the upper mediastinum (Figure 1). The parenchymal window of the thorax computerized tomography revealed a 7x4 cm mass lesion extending from the level of the aortic arch in the left upper lobe to the subcarinal level in the neighborhood of the aorta. In the mediastinal window, it was observed that the mass included necrosis and air bubbles (Figure 2).In the flexible bronchoscopy of the patient, it was determined that the separation of the left upper lobe apicoposterior carina and internal bronchus appeared irregular all around, and there were white nodules on it. The result of the mucosal biopsy that was performed was reported as "extensive squamous metaplasia in the bronchial mucosa epithelium and severe dysplasia. " On the other hand, in the autofluorescence bronchoscopy, the mucosa of the carina between the left upper lobe apicoposterior and anterior segment was swollen, hyperemic, and fluorescent (+). Samples from this region were taken with mucosal and brush biopsies. The result of the pathology was "focal squamous metaplasia in the bronchial mucosa epithelium and dysplasia, " and the result of the brush biopsy was reported as "inflammatory cells. "
