[Differential diagnosis of multiple pulmonary coin lesions--pulmonary hyaline granuloma].

In addition to metastases, the differential diagnosis of pulmonary nodules also includes tuberculosis, sarcoidosis, and silicosis. Rarer diseases such as amyloid tumors, rheumatic nodules, and plasma-cell granulomas can, depending on the clinical situation, be the cause of this finding. For the example of the clinical picture of pulmonary hyalinizing granuloma, the differential diagnosis of multiple pulmonary nodules is illustrated under consideration of the pathognomonic, morphologic observations.

[Surgical treatment of pulmonary coin lesions found in cancer patients and 6 breast cancers. Solitary metastasis? 2d primary bronchopulmonary cancer? Coin lesions of benign nature?].

Pulmonary diffusion of breast cancer is frequent in those patients who have died of the disease and in those survivors who have not been cured after removal of the breast and X-ray treatment in the advanced states of the disease. When the metastases are identified, they are almost always multiple and bilateral. The appearance of a solitary, late, pulmonary coin lesion (metachrone), in someone with breast cancer certainly suggests a pulmonary metastase, but in fact, it is more likely to be a second cancer than a metastase, that is, a primary bronchopulmonary cancer. The presence of a solitary pulmonary coin lesion in someone who has or who has had breast cancer, presents therefore certain particular problems. After having controlled by xerotomography that there is no pulmonary diffusion in either lung, that there is no invasion of other tissues or organs, and after having controlled locally around the breast cancer, then it is imperative to remove the lesion without delay since it is certainly malignant and most probably a second cancer, that is, a primary bronchopulmonary cancer, an adenocarcinome, detected at an asymptomatic stage. The prognosis of a broncho-pulmonary adenocarcinome depends on the precocity of its removal.

Human pulmonary dirofilariasis: uncommon cause of pulmonary coin-lesion.

Pulmonary dirofilariasis is a rare entity caused by Dirofilaria, a dog worm that is transmitted to humans by mosquitoes. The filarial nematode enters the subcutaneous tissue, travels to the right ventricle, dies and then embolizes the pulmonary vessels causing a small pulmonary infarction, which subsequently appears as a solitary nodule. Although these nodules are usually identified incidentally by chest radiography in asymptomatic patients, the lesion is generally presumed to be neoplastic. Diagnosis is made by surgical excision. Awareness of this benign entity is important in the differential diagnosis of pulmonary coin-lesions.

[Diagnosis and differential diagnosis of solitary pulmonary coin lesions].

In the present analysis, the diagnosis as well as the differential diagnosis of solitary pulmonary coin lesions are discussed. The coin lesions of 361 patients who were at our diagnostic ward from 1968 to 1970 were defined according to Rube [1967]. The investigations are in accordance with the routine examinations and were consciously demonstrated in nonselected patients in order to express the several diagnostic procedures, their field of indication and their efficiency in a balanced ratio. Therefore, the efficacy of the X-ray diagnosis could be proved in a broader range than in a collective of circular foci which would have been chosen exclusively under the aspect of the diagnosis by means of needle biopsy and which would reveal a higher percentage of morphological clarification of the focus.

Fibroleiomyomatous hamartoma: a rare benign pulmonary "coin lesion".

A discussion of pulmonary hamartomas is presented along with a case presentation of a rare form, the fibroleiomyomatous variety. The need to differentiate these tumors from primary or even secondary malignant neoplasms always requires tissue diagnosis, necessitating surgical excision.

[Transbronchial needle-aspiration cytology (TBAC) in fiberoptic bronchoscopy in the diagnosis of pulmonary coin lesion].

The coin lesion of the lung is a frequent nearly always occasional radiological discovery and represent a diagnostic problem. But the drawing of a sample suitable for a cyto-histological study from the coin lesion can lead the physician to the correct diagnosis and to the fit therapy. Through the bronchofiberscope the sample can be obtained by transbronchial biopsy (TBLB), brushing, bronchoalveolar washing and now also by transbronchial fine needle aspiration (TBAC). Transbronchial aspiration (TBAC), devoid of hemorrhagic complications, is not a method apart; on the contrary it is complementary method for the diagnosis of pulmonary coin lesion.

[Detectability of pulmonary coin lesions: a comparative assessment of the image quality of a storage phosphor system and a conventional film screen system].

The object of this study was to compare the prototype of a storage phosphor digital radiography system (Siemens) which allows postprocessing image data adjustment with the stored information, with an optimised conventional film system with respect of image quality and diagnostic accuracy. The test objects were pulmonary coin lesions as the search for primary or secondary lung tumours is one of the most frequent clinical requests and the detectability of coin lesions depends very much on their relative contrast against the surrounding area. In order to achieve reproducible results, an anthropomorphic lung phantom was used. Besides the conventional film radiograms the unprocessed digital radiograms and twelve series with variations of the processing parameters were evaluated. To achieve a homogeneous radiation image an anatomically shaped lead-loaded acrylic glass compensation filter was used. With regard to the true-positive demonstration of coin lesions there were no significant differences between the chosen film system and all digital radiograms. Image processing had no recognisable influence on the demonstration of the findings. Coin lesions of 3 mm diameter were detected only by chance; the detectability of lesions of 5 mm and 10 mm in diameter respectively depended mainly on their localisation. Lesions of 15 mm diameter were detected independent of their localisation. The results indicate that the storage phosphorus radiography system is already comparable to an optimised conventional film system concerning the conspicuity of coin lesions. If the image is homogenised by means of an anatomically shaped lead-loaded acrylic glass compensation filter, selective postprocessing adjustment of the digital radiograms for the evaluation of the mediastinum or the lung parenchyma is unnecessary.

[Comparison of the value of general and oblique images and whole lung tomography in a high kilovoltage technic in the detection of pulmonary coin lesions].

The ranking of high kvp pa. and lateral chest x-ray, left and right oblique films and whole lung tomography in the detection of pulmonary coin-shaped lesions is compared. Out of a total number of 327 coin lesions in 115 patients detected by high kvp whole lung tomography, only 52% were found on pa and lateral chest films. Additional oblique films improved the score to 64%. Oblique films proved to be especially helpful in detecting pleural lesions. Although CT has a higher sensitivity in detecting nodules (with decreasing specificity) whole lung tomography will continue to play an important role in the management of tumour patients.

[Insidious aspects of small pulmonary coin lesions].

After his girl friend had been diagnosed with active pulmonary tuberculosis, a 45-year old male was referred to rule out transmission of this disease. The chest x-ray showed no signs of tuberculosis, however a small retrosternal lung nodule was found on the lateral film. Three months later, the nodule showed an increase in size and a CT of the chest was performed: No nodule could be found in the expected retrosternal location, but incidentally a small nodule in the right upper lobe was identified. This nodule could retrospectively be identified on the previous chest X-rays, its size had been increasing. After surgical removal, the lesion was diagnosed to be an adenocarcinoma T1, N0, M0. Careful follow-up of small intrapulmonary nodules detected on chest X-rays is highly advisable, especially in smokers of middle and older age bronchial carcinoma and therefore a straight forward approach with excision of the nodule should be considered. Nodules have to be surgically removed if an increase in size can be noted.

Pulmonary coin lesions: a ten-year review of 239 cases.

The results of a study of 239 resected solitary pulmonary nodules are presented; 66.5% of the resected nodules were malignant, and there were three patients with malignant coin lesions who were under 30 years of age. These findings confirm the generally accepted fact that most solitary pulmonary nodules must be resected if the presence of cancer is to be excluded. Transbronchial biopsy under biplane fluoroscopic guidance through a flexible bronchoscope may provide an effective alternative to early thoracotomy in the future, so that malignant nodules can be diagnosed before operation and patients with benign lesions are spared a thoracotomy.

[Efficacy of minimally invasive thoracic surgery in diagnosis of pulmonary coin lesion].

AIM OF THE STUDY: With only a few exceptions every pulmonary nodule of unknown dignity has to be clarified by biopsy. Aim of the present study was to analyze the usefulness of minimal invasive thoracic surgery in patients with indeterminate pulmonary lesions. METHODS: In the study included were 121 patients (67 male/54 female), who were primarily treated by minimal-invasive surgery during the period 1992-1995. Preoperatively, a single pulmonary nodule was diagnosed in 89 patients. 32 patients had two or more lesions. RESULTS: Using the minimal invasive approach a pulmonary nodule was successfully localized and resected in 83 (68.5%) patients. In 33 patients the operation was classified as diagnostic, in 36 patients benign or inflammatory tumors were completely resected and in 14 patients palliative resections of malignant tumors were performed. Overall, an extension of the operative approach was necessary in 38 (31.5%) of the patients. In 23 patients a "mini-thoracotomy" (< 5 cm) was used to localize the nodule. A standard thoracotomy was performed in 15 patients, mostly because of massive adhesions. CONCLUSIONS: The minimal invasive approach has become a routine procedure in thoracic surgery and is extremely useful in the diagnosis of indeterminate pulmonary nodules.

[Differential diagnosis of multiple pulmonary coin lesions. Lymphomatoid granulomatosis].

In addition to metastasis, the differential diagnosis of multiple pulmonary nodules also includes tuberculosis, sarcoidosis, and silicosis. Rarer diseases such as amyloid tumors, rheumatic nodules and plasma-cell granulomas can be the cause of this finding. This depends on the clinical manifestation. Based on clinical findings of lymphomatoid granulomatosis, the problems in diagnostics using bronchoscopy, mediastinoscopy and thoracoscopy are outlined. Etiology, morphology and differential diagnosis of lymphomatoid granulomatosis versus necrotizing inflammatory or neoplastic lesions are discussed. Treatment and prognosis are described.
