ObjectiveTo investigate researches on inflammatory pulmonary pseudotumor between 2010 and 2014 year and to provide reference information for the majority of professionals in deep research. MethodsBibliographies from research literature of inflammatory pulmonary pseudotumor between 2010 and 2014 year in PubMed database were downloaded, the publication year, journals, countries of publication, the first authors and the frequency of major topic headings were counted by Bicomb 2.0 software. The affiliations were analyzed artificially. Major topic headings appeared no less than three times were intercepted as high frequency terms and high frequency. Major topic headings co-occurrence matrix were formed. SPSS 22.0 statistical software was applied for clustering analysis with matrix, then to get the topic hotspots. ResultsA total of 62 literatures were screened out. The data of research trend, journals, research degree of different countries were acquired. The number of high frequency major topic headings was 12 and among which 4 research hotspots were clustered. ConclusionResearches on inflammatory pulmonary pseudotumor are mainly in terms of pathology, diagnosis and treatment, etiology, and immunoassay.
Objective To investigate the reasons, status, treatment and precautions of misdiagnosis of pulmonary inflammatory pseudotumor. Methods Between January 2005 and December 2015, one hundred eighteen articles about pulmonary inflammatory pseudotumor published in Wanfang and CNKI databases were retrospectively analyzed, among them forty-four articles referring to misdiagnosis rate. The misdiagnosis rate, distribute of misdiagnosed diseases, reasons and main means of definite diagnosis were analyzed. Results There were 1 286 cases of pulmonary inflammatory pseudotumor in the 44 articles, of them 1 012 cases were misdiagnosed. The misdiagnosis rate was 78.84%. Pulmonary inflammatory pseudotumor was often misdiagnosed as lung cancer (65.81%), tuberculosis (15.42%, which included 72 cases of tuberculoma and accounted for 7.11%) and benign pulmonary neoplasms (9.59%). Most misdiagnosed patients did not suffer from adverse consequences, except a few patients undergo unnecessary extended operations. Lack of specificity in clinical manifestations, lack of awareness about the disease, dependent on auxiliary examination and lack of awareness about the fine feature of the disease were the main reasons of misdiagnosis. The majority of misdiagnosed cases were terminal pathological diagnosed through the operation or after percutaneous biopsy. Conclusions Pulmonary inflammatory pseudotumor is lack of specificity in clinical manifestations and easy to be misdiagnosed. It is very important to analyze and identify the fine feature of imaging changes. To reduce and avoid misdiagnosis, clinicians should improve the awareness of this disease.
ObjectiveTo improve the diagnosis and treatment of the disease, the clinical symptoms, pathological features, diagnosis and differential diagnosis, treatment and prognosis of massive lung inflammatory myofibroblastic tumor (IMT) were analyzed.MethodsA case, admitted to the Department of Respiratory and Critical Care Medicine of Xiangya Hospital, Central South University, diagnosed as massive lung IMT, was retrospectively analyzed. His clinical and chest radiological data were collected and literature which searched through CNKI, WanFang Med online and PubMed on this subject were reviewed.ResultsThe patient, middle-age male, was presented with cough, dyspnea and weight loss, whose chest radiology was characterized by a large thoracic cavity occupation. He was confirmed with massive lung IMT by several lung biopsy. From above databases, 8 cases were retrieved, including 6 articles in English and 2 articles in Chinese. In 9 cases of massive lung IMT, there were 4 males and 5 females. The age was from 1.5 to 75 years old and the average age was 28 years old. The clinical symptoms were non-specific, and chest imaging was characterized by a large thoracic occupation. One case had distant metastases with bone, adrenal gland and lymph node, and one case had distant metastasis with brain after complete surgery.ConclusionsLung massive IMT has no characteristic clinical and radiological features. And a definite diagnosis depends on pathological biopsy and immunohistochemical analysis. It needs to be differentiated from other thoracic giant tumors. The preferred treatment is complete surgical resection. The prognosis after complete resection is usually good, and probably affected by size.
