Purpose To investigate the clinicopathologic changes of the lung epithelial tumor with epithelioid granuloma. Methods E-leven cases of lung malignant tumor with epithelial epithelioid granuloma reaction were studied according to the histological changes of lung epithelial tumor, immunophenotype, acid-fast staining, and tuberculosis PCR test results combined with follow-up data. Results The mean age was 62. 3 years, and male to female ratio was 10∶ 1. The main clinical manifestations displayed a cough, chest pain, fever and hemoptysis or bloody sputum. Nine cases were malignant tumors, tuberculosis or inflammatory lesions was 1 case each in pre-vious surgery. The tumor with epithelioid granuloma formation of the 11 cases displayed in the same site ( mixed) . The histopathologic changes of the lesions showed a epithelioid or typical tuberculous granulomas formation, including 4 cases of adenocarcinoma, 5 cases of squamous cell carcinoma and 2 cases of neuroendocrine tumors. The acid-fast bacilli staining was positive in 3 cases;6 cases were positive for PCR detection of mycobacterium tuberculosis. 5 patients died within 2 years due to various causes. Conclusions The lung epithelial tumors with epithelioid granuloma is more commonly found in the middle-aged, The signs and symptoms of the patients are similar to primary epithelial malignant tumors of the lung . The biological behavior was progressive with poor prognosis. The diagnosis of the lesions depends on pathological examination. It is very important to pay more attention to the pathological examination, especially in lung puncture samples, and the differential diagnosis for a definate diagnosis and treatment.

Objective: Signet-ring cell carcinoma is a relatively rare cancer which occurs principally in the stomach,colon-rectum,bladder and breast,but seldom in other parts.This article analyzes the clinical and pathologic features of 3 extremely rare cases of primary signet-ring cell carcinoma in the uterus.Methods: Three cases of primary signet-ring cell carcinoma in the uterus were observed by HE and immunohistochemical staining,their clinical features analyzed and the relevant literature reviewed.Results: Of the 3 cases,2 presented nodose tumors in the cervix while the other in the uterine cavity.Histologically,there was a diffuse infiltration of the tumor cells,with an appearance of signet-ring cells.Periodic acid-Sciff(PAS) staining revealed PAS-positive diastase resistant introcytoplasmic material.Immunohistochemically,the tumor cells were positive for CK and CEA.Conclusion: Primary signet-ring cell carcinoma of the uterus is extremely rare.It is always necessary to rule out a metastatic neoplasm by clinical examination and to differentiate it from other tumors/lesions with signet-ring cell features.

In order to better play an important role of pathology consultations in the routine work of clinical pathology,and to solve the problems presented during consultation,we comprehensively analyze the reasons that cause pathology consulation,the pathological data management,patient-physician dispute,medical liability,as well as other aspects involved in consulation.Meanwhile,measures to resolve these problems are also proposed.

The human atrial muscle cells were investigated by ultrastructural CMPase cytochemistry and atrial natriuretic factor (ANF) immunocytochemistry. The primary lysosomes and ANF were labelled by these techniques, respectively. ANF was localized in the atrial specific granules, these granules were similar in size and 0.20? 0.051?m in diameter, distributed over the entire cytoplasm, preferentially being located in the subsarcolemmal and perinuclear region and forming clusters. Primary lysosomes were various in size, 0.30?0.191?m in diameter, significantly larger than atrial specific granules (P

Purpose To study the clinicopathologic features retrospectively and to explore the prognosis of 15 cases of young pulmonary primary salivary gland tumor. Methods The 15 cases of young pulmonary primary salivary carcinoma were analyzed respectively. Re-sults The 15 cases showed 7 cases with adenoid cystic carcinoma and 8 cases with mucoepidermoid carcinoma. Cough and bloody sputum were main symptoms, while chest pain, chest distress and fever were less seen. There were 10 cases performed with partial pul-monary lobectomy, 3 cases performed with unilateral total lobectomy, 1 case performed with artery perfusion treatment and bronchial ar-tery embolization and 1 case performed with conservative treatment for pancreatic metastasis after diagnosis. The mean follow-up time was 28 months ( from 4 to 96 months) . Conclusion The primary salivary gland-type lung tumor belonged to benign or low-grade ma-lignant tumor, mainly accompanied with hacking cough and bloody sputum, which was commonly found in trachea and bronchus. Final diagnosis could be made through bronchoscopy and biopsy. Complete surgical excision is the primary method and the prognosis is usual-ly good, especially in the young.

Objective To explore the characteristics of blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) in healthy native kidneys. To investigate the relationship between BOLD-MRI and common physiological in-dexes. Methods GE 3.0T MRI scanner and Torsopa phased-array coil were employed to acquire renal coronal T1WI and BOLD image. Ninety patients who were ruled out chronic kidney diseases underwent BOLD-MRI with T2*-spoiled gradient recalled echo (T2*SPGR) sequence. BOLD images were analyzed on R2*map software. Cortical and medullary R2*values were analyzed in bilateral kidneys and in different gender. Different regional R2*values in cortex and medulla were also ana-lyzed. Physiological indices including age, body height and weight, body mass index (BMI), body surface area (BSA), estimat-ed glomerular filtration rate (eGFR) were recorded. Correlation between R2*value and physiological indices were analyzed. Results Bilateral renal cortical R2*values [left (16.56±1.40) Hz and right (16.66±1.28)Hz, respectively] were less than val-ues in medulla [left (28.82±3.71)Hz and right (28.36±3.72)Hz, respectively]. Female and male cortical R2*values [female (16.55±1.30Hz) and male (16.66±1.38)Hz, respectively] were also less than corresponding values in medulla [female (28.46± 3.64) Hz and male (28.70±3.78) Hz, respectively]. In bilateral renal medullary region, R2*values in low pole (27.29±3.05) Hz was less than values in middle (29.32±3.47) Hz and upper pole (29.16±4.21)Hz (F=15.184, P<0.001). Age was positive-ly correlated with R2* values in medulla (r =0.284, P =0.002). However, eGFR was negatively correlated with medullary R2*value (r=-0.232, P=0.007). Conclusion R2*values reflected the levels of renal partial pressure of oxygen and as-sessed the degree of renal ischemia. BOLD MRI could offer a simple, convenient and noninvasive method for to evaluate renal oxygen metabolism in cortex and medulla.

Objective When pathologists from hospitals at various levels encounters pathological sections diffcult to make clear diagosis, it is necessary to invite pathologists from higher hosiptals or special hospitals for pathologic consultation.In the study, we compared the pathological diagnosis of cases sent to other hospitals for pathological consultation with the original diagnostic result to analyze the differences by the evaluation on the impact of these differences on the treatment and prognosis of these patients, which would provide an effective evidence for the quality control of pathological diagnosis. Methods Cases initially diagnosed at the de-partment of Nanjing General Hospital and later sent to other hospitals for pathological consultation from 2010 to 2014 were collected. All the diagnostic results were examined by at least 3 senior pathologists to find exact diffrences between consultation results and origi-nal diagnostic results. Results Among 2055 cases, it was found that there were 1813 cases (88.2%) without diagnostic discrepan-cy, while 218 cases (10.6%) with minor diagnostic discrepancy and 24 cases (1.2%) with completely distinct diagnostic results. Conclusion The diagnostic results of the vast majority of consultation cases are in accordance with the original results, despite of di-agnostic discrepancies in some cases due to the complexity of disease. Expert consultation has reference for the pathological diagnosis of complicated cases, which also plays a potent supervisory role on the quality control of original pathologic results.

Purpose To investigate the expression and significance of HLA-G in ovarian serous carcinoma ( OSC) . Methods HLA-G antigen was immunohistochemically labeled on paraffin-embedded sections of 108 OSCs. The relationship between HLA-G expression and the clinicopathologic parameters was studied. Results The positive expression of HLA-G was observed in 58. 33% (63/108) of OSC tissues. Positive expression of HLA-G was significantly related with lymph node metastasis, recurrence, occurrence site, FIGO stage and MDACC grading system (P<0. 05). In survival analysis, the expression of HLA-G was significantly relevant to prognosis (P=0. 015). Multivariate Cox analysis showed the expression of HLA-G was an important prognosis factor of OSC (P=0. 01). Con-clusion The positive expression of HLA-G could predict high grade and advanced stage of OSC as well as poor prognosis. Also it could distinguish high-grade OSC from low-grade OSC.

Objective At present, there are few studies about myelolipoma within adrenal cortical adenoma.Our aim was to provide more basis for correct diagnosis and treatment by investigation into its clinical and pathological features.Methods The clinical and pathological data were retrospectively reviewed in 11 patients of myelolipoma within adrenal cortical adenoma, along with relative literature reviews.Results The median age of 11 patients (7 females, 4 males) was 49±9.5 years, among whom 3 patients presented Cushing's syndrome, 1 patient with more than 10 years' recurrent dizzy with hypertension, other 7 patients were found coincidently by routine examination.Adrenal mass were found by imaging examination.Pathologically, myelolipomas were in solitary nodule distribution and/or admixed with adrenal cortical adenomas.Myelolipomas were composed of variable admixture of mature adipose tissue and hematopoietic elements.Surgical treatment was performed for all 11 patients, and no relapse was found in 2 months' to 11 years' follow-up.Conclusion Myelolipoma within adrenal cortical adenoma is extremely rare, which is common in females.The patients may present with Cushing's syndrome, hypertension or without obvious clinical syndrome.All the patients are in favorable prognosis after surgical resection.
