Difficult case in the diagnosis of pineal tumor with ectomesenchymal differentiation: teratoma versus pineal anlage tumor.

Pineal region tumors are rare and heterogeneous including germ cell tumors, pineal parenchymal tumors and neuroepithelial tumors. Amongthe pineal region tumors, germ cell tumorssuch as germinoma and teratoma are the most common, followed by pineal parenchymal tumors. We have discusseda case of 20-year-old woman...Continue reading →

Automated counting of Ki-67 labeling index compares with eyeballing estimation to predict behavior of pituitary adenoma.

Pituitary adenoma has been classified as benign according to slow-growing tumor. However, some atypical pituitary adenoma may have clinical aggressiveness such as parasellar invasion and high recurrence rate.Many studies have failed to demonstrate a correlation between Ki-67 labeling index and behavior of this tumor....Continue reading →

Specificity of cytologic features of metastatic lung adenocarcinoma in malignant pleural effusion

Metastatic lung adenocarcinoma is commonly presented with effusions. The cytologic examination of the fl uid is one of the fi rst diagnostic techniques attempted in these patients.

Accuracy in distinguishing between primary adenocarcinoma of cervix and adenocarcinoma of endometrium from curettage specimen by immunohistochemistry

Endometrial and endocervical adenocarcinomas can seem histologically identical and it can be diffi cult to determine the primary site of origin based on morphology alone. As the distinction is signifi cant and cannot always be made on the basis of clinical fi ndings, various immunohistochemical panels have been proposed to aid in determining...Continue reading →

Prevalence of Microsatellite instability (MSI) determined by immunohistochemical staining of MSH6 and PMS2 in patients with colorectal adenocarcinoma

Microsatellite instability(MSI) is one of the genetic abnormalities that leads to colon cancer. The defect, known as mismatch repair genes(MMR) can be either sporadic or a germ line mutation. A immunohistochemical study is one of the methods to detect MMR defects. Lots of different treatment modalities and prognosis are needed to distinguish cancer...Continue reading →

Pulmonary neuroendocrine hyperplasia in hemoglobin Bart-induced hydrops fetalis. A model for chronic intrauterine hypoxia

The pulmonary neuroendocrine system consists of pulmonary neuroendocrine cells (PNECs) and neuroendocrine bodies (NEBs) distributed throughout the respiratory epithelium which regulate lung growth and maturation in the antenatal period. Abnormalities in this system have been linked to many hypoxia-associated pediatric pulmonary disorders....Continue reading →
