“…According to Iwasaki et al (5), 20 cases of PMC had been reported so far, in patients ranging from 29 to 75 years (median, 64 years) of age, with no patient gender difference (6). The majority of patients were asymptomatic and the lesions were discovered incidentally, but some presented with non-specific respiratory symptoms including cough, chest pain, dyspnea, and bloody sputum (5, 7, 8). …”

Pulmonary Mucinous Cystadenocarcinoma: Report a Case and Review of CT Findings

A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral stippled calcifications that demonstrated low-attenuation with no enhancement after contrast administration; 18F-fluorodeoxyglucose (FDG) PET/CT demonstrated mild heterogeneous FDG uptake. The mass was diagnosed as adenocarcinoma with mucin production by transbronchial lung biopsy. Right middle lobectomy was performed, and the pathologic examination disclosed a pulmonary mucinous cystadenocarcinoma.

“…Therefore, a formal anatomic lobectomy for early stage tumors is probably the correct surgical approach as mentioned by Mann et al (19). The role of adjuvant therapy chemotherapy or radiotherapy is not established (7), and given the unclear natural history of PMC, careful long-term follow-up study is probably needed.…”

“…4 We screened the English literature based on the PubMed database and found that 19 cases of PMC had been reported so far, although some controversy exists over the number of PMC cases except that of borderline-malignant cases. [3][4][5][6][7][8][9][10] The characteristics of PMC cases including ours are summarized as follows. There were 11 men and 9 women who ranged in age from 29 to 75 years (median 64 years).…”

Pulmonary mucinous cystadenocarcinoma (PMC) is a rare tumor characterized by mucin production. It is similar to tumors of the same name arising in the ovaries and pancreas. Here we describe the 20th case of PMC reported in the English literature. The patient was a 75-year-old woman with a 3-day history of bloody sputum. Chest radiography and computed tomography revealed a cavitary mass 5 cm in diameter in the posterior segment of the right lung. 18F-fluorodeoxyglucose positron emission tomography demonstrated intense uptake in the wall of the lesion. Right lower lobectomy was performed, and the pathology examination revealed this tumor to be a PMC. The preoperative serum CA 19-9 level was 162.3 U/ml (cutoff 37 U/ml) and decreased to 22.8 U/ml after resection. No mutation of epidermal growth factor receptor or K-ras gene was detected. Thoracic surgeons should bear in mind this rare tumor for the differential diagnosis of a pulmonary cystic lesion.

INTRODUCTIONPrimary Pulmonary Mucinous Cystadenocarcinoma PPMC is an extremely rare subtype of pulmonary adenocarcinoma, with only a few dozen cases reported in the literature to date.PRESENTATION OF CASEWe report a extremely rare case of pulmonary mucinous cystadenocarcinoma presenting as a pleural mesothelioma. 53-year-old man exposed to asbestos, he is admitted in hospital with a 5 cm mass in right pleura. He was treated by wedge resection. Sparse groups of malignant cells were microscopically observed in pools of mucin. The postoperative histopathological findings were in accordance with the diagnosis of pulmonary mucinous cystadenocarcinoma on cystic adenoid malformation of lung. 5 years later, the patient has no recurrence.DISCUSSIONPPMC is usually asymptomatic; hemoptysis is seen occasionally. Preoperative diagnosis is very difficult to establish. Both FNA cytology and transbronchial lung biopsy seem inadequate. Our patient went on to undergo open lung biopsy and histopathological testing that confirmed the diagnosis of PMC.CONCLUSIONIt is important to differentiate this rare pathological feature of the lung from other lung tumors as the treatment is surgical rather than medical. Thoracic surgeons should bear in mind this rare tumor for the differential diagnosis of a pleural mesothelioma because this tumor has a favorable prognosis.
