Primary pulmonary mucinous adenocarcinoma in a non-smoker woman Among them, primary pulmonary mucinous adenocarcinoma former bronchioloalveolar carcinoma is rarely encountered, with atypical presentation, which lends itself to diagnostic confusion. We present the case of a year-old, non-smoker female patient who presented for chronic cough for over a year, accompanied by mucous expectoration and dyspnea in decubitus. Radiologically she presented condensation processes in bilateral extension.
Computed tomography showed condensation processes and bilateral nodules lung cancer benign pleural effusion aeric bronchogram and a possible left lower lobe tumor process. The bronchoscopy with bronchoalveolar lavage was non-diagnostic, the confirmation of mucinous adenocarcinoma being made by surgical pulmonary biopsy.

Prezentăm cazul unei paciente de 78 de ani, nefumătoare, care s-a prezentat pentru tuse cronică de peste un an, însoțită de expectorație mucoasă și dispnee de decubit. Radiologic, prezenta procese de condensare în extensie bilaterală. Examenul tomografic computerizat a evidențiat procese de condensare și noduli bilaterali cu bronhogramă aerică și un posibil proces tumoral de lob inferior stâng.

Case presentation Figure 1. Standard radiographic appearance at symptoms onset: condensation process in the left lower lobe A year-old female patient was admitted by transfer from a provincial pneumophtisiology hospital for diagnosis. The female patient, who was not a smoker and had a history of hypertension in treatment, without any exposure, had chronic cough for more than a year, which had associated dyspnea at exertion and dyspnea in decubitus for the past 6 months.
She received inhaled bronchodilators without symptom relief. In Octobera pulmonary radiological examination revealed a left basal pulmonary consolidation, considered a left lower lobe pneumonia, for which she received oral antibiotic treatment Figure 1.
The radiological image remained unchanged after one month.

In Octobershe was hospitalized due to intensified cough, which became productive with abundant mucous expectoration; the radiological image showed this time the persistence of the left basal consolidation and the addition of multiple bilateral condensation processes Figure lung cancer benign pleural effusion.
Tumors of the Lungs Step 1 and 2 In hospital, she received antibiotics beta-lactams and fluoroquinolones and inhaled bronchodilators, without improvement of the symptoms.
Figure 2. Standard radiological appearance at one year of evolution: multiple bilateral pulmonary condensation processes A chest computed tomographic scan Figure 3 has been performed, showing numerous bilateral opacities, some nodules of different dimensions, ill defined, with aeric bautura detoxifianta cu ghimbir or tendency to excavate, bilateral non-systemic consolidations with aeric bronchogram, as well as a possible tumor practically occupying the entire left lower lobe accompanied by a small left pleural effusion.
[Thoracoscopic Pleurodesis in Malignant Pleural Effusions]
Figure 3. Pulmonary auscultation revealed multiple bilateral subcrepitant crackles and ronchuses. There was no peripheral adenopathy, the rest of the physical examination was normal. Serologic tests showed a mild anemia hemoglobin The rest of the performed tests were normal. A fibrobronchoscopic examination was performed which did not reveal macroscopic changes in the bronchial mucosa. A broncho-alveolar lavage BAL in the left lower lobe bronchus was attempted, without recovery of the lavage fluid, therefore BAL lung cancer benign pleural effusion performed in the territory of the left upper lobe bronchus, with a good recovery of a slightly opalescent liquid.
Differential cytology of the lavage fluid showed very mild lymphocytosis At this point, based on the symptoms and the imaging aspect, several diagnostic assumptions were considered: diffuse interstitial pneumonia, possibly a granulomatosis with polyangeitis, due to the presence of excavated nodules, but the serology for the cANCA and pANCA antibodies was negative; a lung infection, but the long evolution with afebrility, the lack of response to antibiotic treatments and the absence of germs or mycobacteria in the BAL fluid contradicted the hypothesis; a primary pulmonary neoplasia of the type of a mucus-secreting adenocarcinoma or multiple pulmonary metastases of extrapulmonary origin, but was not supported by the presence of tumor cells in the bronchoalveolar lavage fluid.
The need for a surgical pulmonary biopsy has been called into question, in order to lung cancer benign pleural effusion the diagnosis with certainty. Despite the advanced age, the patient had a good overall condition with no signs of heart failure, with a normal electrocardiogram, and the ventilatory function measured by spirometry was normal vital capacity of 1. Adenocarcinom mucinos pulmonar primitiv la o femeie nefumătoare The patient was transferred to the thoracic surgery department and pulmonary biopsy was performed in the middle lobe through a thoracoscopic approach.
The postoperative evolution was without complications, the patient being discharged after 3 days.
The histopathological examination of the resection piece revealed a mucinous adenocarcinoma with neoplastic infiltration and a predominantly lepidic pattern, acinar and papillary zoning, consisting of goblet cell carcinoma cellular elements Figure 4.
Figure 4. For this, additional investigations have been carried out.

Mammography did not reveal mammary tumors. Repeated CT scan with the inclusion of the cerebral, abdominal and pelvic segments excluded abdominal or lung cancer benign pleural effusion tumors or adenopathies, revealing only an lung cancer benign pleural effusion mm right anexial cyst with a residual cyst aspect.
Abdominal echography did not reveal biliary or pancreatic changes.
The patient was subsequently hospitalized in the oncology department where therapy with gemcitabine and platinum salts was initiated, being well-tolerated, and improved the cough. It was originally described as a form of peripheral carcinoma, growing cancerul ovarian se transmite a single layer of malignant cells along the terminal airways.
Primary pulmonary mucinous adenocarcinoma in a non-smoker woman Mucus production is characteristic of this type of adenocarcinoma 2,3. Patient survival depends on the extent of the disease at the time of diagnosis, lung cancer benign pleural effusion the predominantly lepidic type appears to have better survival than other histological types 4.

From the clinical point of view, these carcinomas have a long evolution, with symptoms dominated by productive chronic cough with mucous expectoration that can become abundant, originating in mucus production of tumor cells 6.
From the imaging point of view, the initial changes on standard pulmonary X-ray suggest lung cancer benign pleural effusion pneumonia that does not improve under antibiotic treatment, and the appearance over time of new condensations in both lungs is characteristic. The thoracic CT examination detects, besides the condensation processes, nodular opacities of various dimensions, predominantly in upper lobes, with ill defined limits, different sizes and the presence of aeric lung cancer benign pleural effusion, pseudocavities and lung cancer benign pleural effusion.
Changes are not characteristic, predisposing to diagnostic confusion 7. Positive diagnosis is lung cancer benign pleural effusion on histopathological and immunohistochemical confirmation, though it is often difficult to distinguish between a primitive pulmonary carcinoma and secondary determinations from a carcinoma outside the lungs.
Primary mucinous pulmonary adenocarcinomas are rare tumors, however, literature citations are marked by classification difficulties Also in the case of our non-smoker patient, the symptomatic evolution of the disease was marked by confusion with a pneumonia or a chronic obstructive disease, and the diagnosis could only be confirmed by surgical lung biopsy. Conclusion The presented case raises the problem of the difficult differential diagnosis of a rare type of pulmonary cancer, primary mucinous adenocarcinoma, in which positive diagnosis and differentiation from other infectious or inflammatory pulmonary diseases could only be performed by surgical pulmonary biopsy.
