Clinical, pathological, and radiological characteristics of solitary ground-glass opacity lung nodules on high-resolution computed tomography.

Background: Lung nodules are being detected at an increasing rate year by year with high-resolution computed tomography (HRCT) being widely used. Ground-glass opacity nodule is one of the special types of pulmonary nodules that is confirmed to be closely associated with early stage of lung cancer. Very little is known about solitary ground-glass opacity nodules (SGGNs).

ACTH-secreting pancreatic neuroendocrine carcinoma with ovarian and pelvic metastases causing Cushing's syndrome: a case report.

Adrenocorticotropin hormone (ACTH)-secreting pancreatic neuroendocrine carcinoma (NEC) with ovarian and pelvic metastases causing Cushing's syndrome is very rare and might be misdiagnosed. We describe a case of ACTH-secreting pancreatic poorly differentiated NEC developing bilateral ovarian and pelvic metastases. A 27-year-old woman presented with thirst, polydipsia, fatigue and poorly controlled hyperglycemia.

Suppressive effects of microRNA-16 on the proliferation, invasion and metastasis of hepatocellular carcinoma cells.

miR-16 is known to be abnormally expressed in hepatocellular carcinoma (HCC) cells, and the overexpression of miR-16 inhibits the proliferation, invasion and metastasis of various cancer cells. MicroRNAs (miRNAs or miRs) are closely related to the proliferation, invasion and metastasis of HCC. The present study aimed to explore the effects of miR-16 on the proliferation, invasion and metastasis of HCC cells, and to elucidate the mechanisms involved.

Immunohistochemical differentiation between type B3 thymomas and thymic squamous cell carcinomas.

Type B3 thymomas and thymic squamous cell carcinomas have some overlapping histological features, so it is difficult to make the differential diagnosis between these two entities, especially when the biopsy specimen is small. Only a few markers such as CD5 and CD 117 were applied to the differential diagnosis, the purpose of this study is to identify other diagnostic markers to help making the differential diagnosis more accurate. GLUT-1, MUC-1, CD117, CD5, CEA, P63, CK19, CK5/6, CD1a and TdT were evaluated using 16 cases of type B3 thymoma and 20 cases of thymic squamous cell carcinoma.

Thymic epithelial tumors: a clinicopathologic study of 249 cases from a single institution.

The WHO histological classification for thymic epithelial tumors of 2004 edition is widely used, but its prognostic value is still controversial. In the present study we collected 249 Chinese patients with thymic epithelial tumors from West China Hospital of Sichuan University since 1999-2009 to assess the prognosis relating to tumor stages, histological classifications, MG and adjuvant therapy. There were 18 cases of type A (7.

Immunohistochemical screening and fluorescence in situ hybridization confirmation of ALK translocation in lung adenocarcinoma and its clinicopathological significance: a single-center large-scale investigation of Chinese patients.

Anaplastic lymphoma kinase (ALK) translocation-positive adenocarcinoma of the lung is a newly recognized molecular subgroup. Limited data on the clinicopathological features of this entity in the Chinese population are available. We performed immunohistochemical staining for the ALK protein and fluorescence in situ hybridization detection of the ALK translocation.
