Pheochromocytoma is originated from chromaffin cell of sympathetic nervous system and associated with other disease, such as neurofibromatosis, duodenal carcinoid, medullary thyroid cancer and parathyroid adenoma. Especially, pheochromocytoma is developed more than 50% in neurofibromatosis associated with hypertension. In such cases, several clinical features documented as more frequent bilateral phochromocytoma, more associated with other neuroendocrine tumors and thus more poor prognosis. We can observe the sustained hypertension despite of surgical resection of tumors in pheochromocytoma cases. One of the possible reason of post operative sustained hypertension is the pheochromocytoma originated from minor organ of Zukerkandl that was not resected during operation. Untreated or delayed treated cases with pheochromocytoma were often expired by complication of hypertension such as cerebrovascular hemorrhage, myocardial infarction, etc. Thus, in neurofibromatosis with hypertension, screening of pheochromocytorna is very important for the early detection of tumor and more favorable prognosis. Recently, We experienced a case of neurofibromatosis associated with bilateral pheochromocy-toma expired by cerebral hemorrhage during operation, so we report the case with literature review.

Colonic lesions by irritant laxative abuse are devided into melanosis coli, cathartic colon, soap or chemical colitis. Melanosis coli is the brownish or black discoloration of the colon because of the accumulation of lipofuscin pigment in macrophages located in lamina propria and associated with anthraquinone containing laxative abuse. The site of this lesion is more common in cecum and proximal colon, but whole colon can be involved. This lesion is occurred between 4 months and 13 months from initiation of drug medication, and the lesion is benign because the pigments disappear by withdrawning the laxatives. A number of cases were reported in our country, all of the cases were associated with prolonged administration of anthraquinone type laxatives. We presents two cases of melanosis eoli that had administrated aloe to treat the chronic constipation during long terms, and one case of melanosis coli that had not administrated laxatives or a specific drug with chronic constipation. All of three cases were confirmed by colonoscopy.

BACKGROUND: Cancer registries are fundamental for cancer control and multicenter collaborative research. However, there have been discrepancies among pathologists in classifying cancer and assigning the codes according to the International Classification of Disease Oncology 3 (ICD-O3). To improve the quality of cancer registries as well as to prevent the conflict with medical insurance compensation, a guideline for the coding of cancer is mandatory. METHODS AND RESULTS: Funded by the Management Center for Health Promotion, 40 members of the Gastrointestinal Pathology Study Group and the Cancer Registration Committee of the Korean Society of Pathologists participated in the 1st workshop for gastrointestinal tumor registration. The subjects of gastric epithelial tumor, intramucosal carcinoma of the colon, carcinoid tumor, gastrointestinal stromal tumor and appendiceal mucinous tumor were discussed to create a guideline. A survey to obtain consensus for the guideline proposed by the workshop was carried out by the members of the Korean Society of Pathologists and 240 members completed the questionnaire. CONCLUSION: Although there are some issues to be discussed further, such as coding of high grade dysplasia/adenoma and intramucosal carcinoma of stomach and colon, the members agreed upon most parts of the proposed guideline. Therefore, we suggest using the ICD-O3 coding guideline for gastrointestinal tumor.

Cellular schwaninoma is a variant of schwannoma, which is characterized by predominance of cellular Antoni A area, presence of mitotic activity, nuclear hyperchromasia, pleomorphism, and absence of Verocay body. These pathologic features often prompted a misdiagnosis of malignancy. However, the clinical outcome has indicated the benignity of the tumor. We have experienced a case of cellular schwannoma arising from right facial nerve with right hemifacial weakness and erosion of mastoid process. Grossly, it was a 3.5 x 3 cm sized and relatively well encapsulated mass with yellowish, friable cut surface. Microscopically, cellular growth with moderate cellular pleomorphism and some mitotic activity (5/40 HPFS, up to 2/HPF) were noted. Immunostaining for S-100 protein showed diffuse strong positive reaction.

A 46-year-old woman presented with multiple purpuric skin rashes together with splenomegaly and thrombocytopenia. The resected spleen weighed 720 gm, and contained multiple, discrete, dark red, bulging nodules throughout the entire splenic parenchyma. Microscopically, the nodules revealed various range of endothelial cell proliferation which included cavernous vasculature, anastomosing vascular channels, papillary intravascular growth and solid pattern. Intrasinusoidal sequestration of platelets along with extramedullary hematopoiesis was present in the neoplastic vascular spacws. Neither exposure to thorotrast nor vinyl chloride was nonfirmed. Ultrastructurally, the tumor cells demonstrated a row of pinocytotic vesicles, occasional intercellular junctional structures, and the paucity/absence of filamentous structures or Weibel-Palade bodies supports origin of sinus lining type cells. After splenectomy, the thrombocyte count returned to normal. We conclude this is the first case of primary splenic angiosarcoma with Kasabach-Merritt syndrome in Korean literature.

The pulmonary cytology has reached a high level of accuracy. By the examination of the sputum and/or bronchial brushings, it is now possible to make a diagnosis in 70% to 90% of patients with cancer. Primary melanoma of the lung is very rare and there have been reported about 20 cases in the world literature. We present a case of primary malignant melanoma of the lung in a 61-year-old male diagnosed by cytologic examination of sputum, bronchial brushing and aspirated pleural fluid. Histologic examination of bronchoscopic biopsy and examination of the skin and other primary sites confirmed the diagnosis.

Biological behavior of malignant tumors has been assessed by morphological grading, clinical staging, and estimating other tumor markers. Recently DNA ploidy measured by flow cytometry and image analyser has been suggested as an additional useful indicator of the tumor behavior. In order to extract useful tumor cell-specific information in ovarian mucinous tumors, DNA contents and other morphologic parameters were measured by image analysis and DNA ploidy was also measured by flow cytometry. In all cases of cystadenoma, DNA diploidies were observed. In borderline malignancy, DNA diploidies were chiefly observed except one case of polyploidy. In true malignancy, DNA aneuploidies were observed except one case of polyploidy and two cases of diploidies by image analysis, and except four cases of diploides and one cas of polyploidy by flow cytometry. The statistical significance were observed in DNA ploidy pattern by image analysis. In nuclear areas, perimeters and major axis, statistical significance were not observed. These results suggest that DNA ploidy pattern are more or less independent parameter as an additional useful indicator of the histological grade of malignancy and that image analysis are better than flow cytometry in detecting DNA aneuploidy.

Objectives:
This study investigated the relationship between clock-drawing test (CDT) performance and neuropsychological functions in patients with chronic schizophrenia.
Methods:
Thirty-one patients with schizophrenia and 30 healthy controls participated in this study. The CDT was administered in three conditions and analyzed using both quantitative and qualitative scoring systems. Comprehensive neuropsychological tests were administered.
Results:
The results of the quantitative analysis showed that the schizophrenia group performed significantly worse in all three conditions of the CDT compared with the control group. However, no significant differences were observed between the two groups, when the IQ and educational level were controlled. The qualitative analysis showed that the schizophrenia group exhibited significantly more errors in “graphic difficulty” compared with the control group. In addition, CDT quantitative scores were significantly correlated with visuospatial function, memory, attention and executive functions in patients with schizophrenia. Conversely, each qualitative error type was correlated with specific cognitive domains. Furthermore, “graphic difficulty” and “spatial/ planning deficit” were identified as predictors of depression symptoms in patients with schizophrenia.
Conclusion
The present study demonstrated that the CDT is useful for assessing cognitive dysfunctions in patients with schizophrenia, while qualitative analyses provide more specific information about cognitive deficits compared with quantitative analyses.

Pulmonary blastoma is a rare type of malignant lung tumor comprised of epithelial and mesenchymal elements reminiscent of fetal lung. Mesenchymal element may show various patterns of differentiation toward mature tissue, such as cartilage, smooth muscle, and bone. Rhabdomyoblastic differentiation in pulmonary blastoma is quite rare. Our case of pulmonary blastoma with rhabdomyoblastic differentiation documented by electron microscopy and immunohistochemistry. Usually it has been treated with surgery, but both chemotherapy and radiotherapy have been used against the metastatic disease, and as the adjuvant setting. A 28/12-year-old girl is described who was presented with pulmonary blastoma. She underwent surgical excision of the tumor, followed by the T2protocol, a 8 cycles of combination chemotherapy consisting of actinomycin-D, adriamycin, vincristine and cyclophosphamide with the radiation therapy to the left chest cage(180cGyx11 times). The patient has been off therapy without any evidence of relapse for 24 months. We report a case of pulmonary blastoma with brief review of related literatures.
