The differentiation of interstitial lung diseases and disseminated lung tumors only by radiological methods is impossible. Cytological or histological examinations of specimens taken by bronchological or surgical examinations are able to confirm the diagnosis. In two cases of a disseminated process in which other bronchological diagnostic methods failed we found cells of an adenocarcinoma by BAL. We recommend this method for differential diagnostic between interstitial lung diseases and disseminated intraalveolar carcinoma, especially bronchiolo-alveolar carcinoma.

In 140 lung cancer patients fiberoptic bronchoscopy with biopsy and BAL procedure were performed in diagnostic process. Obtained results of macroscopic changes were analyzed in relation to histological diagnosis and localization in the bronchial tree (central and peripheral). Squamous cell lung cancer was the most often diagnosed in central localized tumors and adenocarcinoma in peripheral ones. Macroscopic changes were more evident and more characteristic for cancer process in central localized tumors. In peripheral changes non-characteristic, inflammatory-like symptoms were determined.

A simple radioimmunoassay for detection of secreted and intracellular annexin II in human cells is presented. Annexin II is a multifunctional protein in human cells and may have a role in several types of cancers. No enzymatic activity has been associated with the protein, thus making its detection difficult. Using purified annexin II from human placenta, we have developed a sensitive radioimmunoassay protocol. A linear response was observed up to a concentration of 0.5 microgram purified protein in the assay. Using this radioimmunoassay protocol, annexin II can be detected in undiluted clinical human samples such as bronchoalveolar lavages and various tissue extracts. We demonstrate the applicability of this technique to measure intracellular annexin II in extracts of a human adenocarcinoma cell line (HeLa) and secreted annexin II from bronchoalveolar lavage fluid from a human patient. Using HeLa cell extracts and BAL, we observed a linear response with up to 10 micrograms total protein in the assay. We further demonstrate the applicability of this technique to measure differences in intracellular and secreted annexin II in the human pancreatic adenocarcinoma cell lines CD-11, CD-18 and Capan-2. While CD-11 and CD-18 do not secrete annexin II, the cell line Capan-2 secretes high levels of the protein.

The aim of the study was to assess the diagnostic yield of transbronchial lung biopsy (TBLB) in some of diffuse pulmonary diseases, like: sarcoidosis, organizing pneumonia--(OP), tuberculosis and neoplasmatic infiltrates of the lung. Transbronchial lung biopsy was performed in 123 patients, preceded by high resolution computed tomography (HRCT). The HRCT guidance helped to select the area of lung to be biopsied. In 80 patients (65%) TBLB enabled to diagnose 40 cases of sarcoidosis, 15 cases of OP, 13 cases of neoplasmatic infiltrates of the lung and 5 cases of tuberculosis. There were 43 cases undiagnosed by means of TBLB. In 19 patients the diagnosis was established by means of other methods like videothoracoscopy (8 cases), bronchoscopy with bronchial mucose biopsy (7 cases of sarcoidosis), mediastinoscopy (2 cases of Hodgkin's disease), transthoracic needle biopsy (2 cases of adenocarcinoma). Moreover sarcoidosis was diagnosed in 15 cases by means of clinical, radiological examination and BAL. 9 patients didn't agree for further invasive diagnostics. Transbronchial lung biopsy was shown to be efficient diagnostic method especially in sarcoidosis, OP and neoplasmatic infiltrates of the lung. However, in approximately 35% of cases of diffuse pulmonary diseases this technique doesn't allow to establish a diagnosis. This in turn implicates the necessity for further diagnostic procedures including videothoracoscopic or open lung biopsy.

Bronchioloalveolar carcinoma (BALC) is a sub-type of adenocarcinoma, accounting for 3-5% of all lung cancer cases. It is characterized by peripheral location in lung parenchyma, without visible changes in main bronchi and tumor spread occurs along the walls of the peripheral airspaces without destruction of the pulmonary interstitium. Their carcinomas were classified into three clinicopathologic types: nodular or tumoral, pneumonic, and diffuse types. The disease may take an asymptomatic form for several months or even years. This form of cancer spreads by way of air tracts creating multiple changes in lungs. Metastases to lymph nodes and other organs occur rarely. It is difficult to provide a correct diagnosis. The complete surgical resection of localized BAL C offers the best chances of long-term survival. Patient prognosis is usually more positive than in other histological types, since the disease is frequently diagnosed at its early development stages.

A 67-year-old male presented with cutaneous rash, lassitude and fatigue of three weeks. Personal history included psoriasis and sarcoidosis. Physical examination revealed macular rash on the anterior chest wall. Laboratory results were within normal limits. Chest X-ray showed normal findings. Pulmonary function tests demonstrated a mild obstructive pattern and a mild decrease in DLCO/VA. Thorax CT revealed two nodules in the right upper and middle lobe. 68Ga-citrate PET/CT did not demonstrate any active inflammatory reaction associated with sarcoidosis while 18F-FDG PET/CT revealed increased FDG uptake in the right middle lobe, upper division bronchus and in the left lower abdominal quadrant. Histopathologic examination of the colon biopsy was compatible with adenocarcinoma and bronchoscopic biopsy of the lung lesions revealed nonspecific granulomatous inflammation. BAL cytology was normal while BAL culture did not grow any pathologic organisms. Simultaneous use of 18F-FDG and 68Ga-citrate PET/CT was the hallmark for the final diagnosis in our patient. While FDG/PET has detected the pulmonary and colonic malignant foci in our patient, 68Ga-citrate PET/CT excluded the presence of active granulomatous inflammation of sarcoidosis. Simultaneous utility of these two imaging modalities in patients with sarcoidosis is of great importance in terms of guiding the clinician towards the accurate diagnostic pathway which is the hallmark for final diagnosis, especially in the presence of concomitant malignant disease.
