Radiologic findings of Total colonic Aganglionosis(T.C.A.) were analized in 15 patients with the results asfollows; 1. Male to female ratio was 8:7. 2. There were six cases of small calibered colon, seven cases of normalcolon and two cases of megacolon. 3. Free reflux of barium into the small bowel was observed in seven cases out ofeight in which retrograde filling was tried. 3. Delayed films (24 hrs or more) were available in eight cases andmost of the barium remaned in bowel in six cases. 5. There were abnormal colonic contractions in three cases,decreased redundancy in five and five cases of irregular, hypertrophic mucosal wall suggesting enterocolitis. 6.Part of ileum were also aganglionic in five cases. There seems to be no pathognomonic barium enema findings inT.C.A. But combination of these findings may suggest the possibility of T.C.A. T.C.A. should be considered indifferential diagnosis of bowel obstruction in infants. Barium enema should be complete and delayed films alwaysbe obtained.

Malignant myoepithelioma is a rare neoplasm of salivary gland which may either arise de novo or develop in a pre-existing pleomorphic adenoma. The malignant myoepithelioma occurs in 0.45% of major salivary gland tumors. Malignant myoepitheliomas arising in the pleomorphic adenoma number less than 20 in English literature and 1 in Korea. We describe a case of malignant myoepithelioma arising in a recurrent pleomorphic adenoma of the left parotid gland of a 61-year-old man. The tumor was ill-defined and composed of polygonal or plasmacytoid myoepithelial cells. Infiltration to surrounding tissue, hemorrhage, necrosis, increased mitotic activity and vascular tumor emboli indicated its malignant nature. There were several satellite nodules with histologic features of typical pleomorphic adenoma. Immunohistochemically, tumor cells were reactive for S-100 protein, AE1/AE3, vimentin, smooth muscle actin and glial fibrillary acid protein.

Wernickes encephalopathy is an illness characterized by mental disturbance, paralysis of eye movements and ataxia of gait. The specific factor for most, if not all, of these symptoms is a deficiency of thiamine. Wemicke's encephalopathy mostly occurs in developing countries when the patient is in a state such as nutritionally deprived state, anorexia nervosa, stomach cancer, long duration of parenteral nutrition. Wernickes encephalopathy was recognized as a complication of hyperemesis of pregnancy in 1914. Unfortunately, cases continue to occur. We present here a case of Wernickes encephalopathy in a 36-year-old pregnant woman. We discuss the clinical picture, histopathology, radiology, therapeutic management and prognosis with review of the literature.

Lymphomatoid papulosis, first described by Macaulay in 1558 is a chronic disease characterized by the recurrent self-healing papulonecrotic or nodular skin lision, showing histological features of malignant lymphoma. The clinical course is variable, with rogression to disseminated malignant lymphoma in up to 10-20% of patients. Ki-1 appears to the a representative marker for large cells ir lymphomatoid papulosis and these cells can be detected in l-1 lymphorna, Hodgkins diseasen other disorders with aetivated T cells. However, positive Ki-1 staining is useful for supporting a diagnosis of lymphomatoid papulosis, under the appropriate clinical and histopathologic findings. We report a case of positive lymphomatoid papulosis which is characterized by the typical findings of clinical, histojpathological and immunohistochemica sizdies.

The grading of astrocytoma has traditionally relied on histological assessment, but there are some differences in their parameters, application, and reproducibility. Recently, numerous studies have attempted to correlate biological aggresiveness with tumor proliferation index using new immunohistochemical methods. The purpose of this study is to correlate the histopathological grades of astrocytoma with the expression of Ki-67, PCNA, p53 protein and AgNORs. The paraffin sections of 41 consecutive cases of astrocytomas were examined. Histologically the tumors were graded as three groups under the St. Anne-Mayo system and showed 14 cases in grade II, 15 cases in grade III and 12 cases in grade IV (glioblastoma multiforme). As a result, the Ki-67 labelling index and p53 protein expression tended to increase with increasing grade of malignancy. But the univariate analysis showed that there was no significant difference between the tumor grades (p>0.05). The PCNA labelling index and number of AgNORs revealed striking differences between the grade II and grade III astrocytomas (p<0.05). We concluded that the PCNA labelling index and AgNORs counting are useful markers for differentiation between grade II and III astrocytomas.
