Mucinous tumors of the ovary are the most common tumors arising from the common epithelium of the ovary in Korean. Distinguishing the tumor with borderline malignancy from mucinous cystadenocarcinoma is very important in determining proper therapeutic modalities and prognosis. Authors have undertaken morphometric analysis of various parameters from both borderline lesions and carcinomas of mucinous nature of the ovary. In each, five cases of the borderline and malignant tumors were subjected to be evaluated. Various cytologic and histologic parameters were analyzed using Kontron IBAS-I. 1) The most helpful parameter-for differentiation between borderline and malignant mucinous tumors is cell concentration (sensitivity 80%, specificity 80%). The discrimination value is more than 35 cells per 100 micrometer of the basement membrane length. If the cellular concentration is higher than the discriminating value, that indicates malignancy. 2) Tumor cell height, though it is other parameter of stratification, is not helpful for differentiation of the two lesions. 3) Cytologic atypia, either in size or in form, can not be a criterion distinguishing the borderline from malignancy. 4) Papillary growths can not be a criterion of either borderline and malignant lesions. 5) The degree of irregularity at tumor-stroma interface is not helpful for differentiation between borderline and malignancy.

The purpose of this study was to identify the effectiveness of bladder training on self voiding after removal of catheter in female patients with craniotomy, finally to develop a bladder rehabilitation program for cognitive impaired patients. Nonequivalent control group posttest design was used. The population of this study consisted of 34 hospitalized neurosurgical patients, all patients have been received craniotomy. 17 patients were assigned to the experimental group and another 17 patients to the control group. The homogeneity of general characteristics of the subjects was no significant difference. Bladder training program consisted of pre-training education, the bladder training, positive verbal reinforcement. The experimental group has been received bladder training and the control group has been received gravity drainage. The dependent variables, the frequency of voiding trial untill self voiding achieves, the frequency of urinary retention, the amount of residual urine, the occurrence of urinary incontinence, were measured during 3 days after catheter removed. The data analyzed with SPSSWIN : frequency, percentage, t-test and chi-test were used to analyze homogeneity of general characteristics of subjects between the experimental and the control group. T-test, Mann-Whitney U test, and chi-test were used to determine the effect of bladder training. The results of the study were as follows : There was significant difference in the frequency of voiding trial untill self voiding achieves between the experimental group and the control group. There was no significant difference in the frequency of urinary retention between the experimental group and the control group. There was no significant difference in the amount of residual urine between the experimental group and the control group. However, there was significant difference in the amount of residual urine in urinary retention patients. There was significant difference in the occurrence of urinary incontinence between the experimental group and the control group. In conclusion, bladder training program as a nursing intervention was effective in increasing self voiding ability after removal of catheter for craniotomy patients. Therefore, it is recommended to use the bladder training program clinically for the bladder management of cognitive impaired patients.

Esophageal involvement by malignant lymphoma is extremely rare. A case of follicular lymphoma of the esophagus, misdiagnosed as focal lymphoid hyperplasia (pseudolymphoma) in a 72-year-old man is presented. The esophagogram revealed diffuse narrowing of the lumen in the middle and distal portion without ulceration. The resected esophagus showed mural thickening without any remarkable mucosal change. Microscopically, the esophagus showed scattered follicular lymphoid aggregates in the submucosa, extending into periadventitial fat tissue. Most follicles were devoid of germinal center and consisted of loosely aggregated small cleaved cells without atypia. The surrounding stroma of the submucosa showed dense fibrosis entrapping the infiltrating small lymphocytes in a "indian-file" appearance. There were some reactive follicles with germinal center. In the lamina propria, many plasma cells and a few eosinophils were infiltrated. The gene rearrangement study showed rearranged band for Jk probe which confirmed monoclonal B-cell nature of infiltrated small lymphoid cells. The small cleaved lymphocytes arranged in follicles were positive for L26 and bcl-2 protein. This case demonstrated the necessity of immunophenotypic and gene rearrangement study in the diagnosis of pseudolymphoma in the digestive tract.

Electron microscopic study of two malignant fibrous histiocytomas confirmed the presence of previously described tumor cells in the literature. In addition, there existed intermediate cells with morphologic features of both myofibroblasts and histiocytes, or both histiocytes and smooth muscle cells. Our result supported the idea that malignant fibrous histiocytoma may be derived from the undifferentiated mesenchymal cells that differentiate primarily along a fibroblastic and histiocytic cells.

Eosinophilic cellulitis is a rare dermatosis originally described by Wells as "recurrent granulomatous dermatitis with eosinophilia", then called Wells' syndrome. The etiology is unknown, although a hypersensitivity mechanism is suspected. Flame figures are considered as a characteristic histologic feature of Wells' syndrome. To clarify the nature of eosinophilic cellulitis and its flame figures, the authors have reviewed five cases of eosinophilic cellulitis with its clinical and histopathologic findings. Cutaneous lesions were variable in appearance and was confused with angioedema, urticarial vasculitis, erydiema multiforme, morphea or granuloma annulare. Microscopically, early lesions (2-7 days) showed diffuse dermal eosinophilic infiltration with widespread degranulation, sometimes extended into the underlying muscle. Subepidermal bulla was present in one case. Subsequently, granulomatous features with characteristic "flame figures" became apparent (several months). Collagen alteration by eosinophilic granules resulted in flame figure formation and a granulomatous response. In two patients, there were possible relationships between drug and flare-ups of eosinophilic cellulitis, but the others, no contributory precipitating factors were found. We think that eosinophilic cellulitis represents a severe anaphylactic hypersensitivity reaction to various stimuli showing characteristic histopathology with recurrent episodes and frequent hypereosinophilia in the peripheral blood.

Accidental or suicidal fatalities of paraquat (Gramoxon) poisong are occasionally seen in the emergency room or intensive care unit in this country. In most cases, respiratory symptoms and eventual death by respiratory distress occur within several days. The most striking pathologic change is fibrosis of the lung due to widespread proliferation of fibroblastic cell. We experience a 21-year-old woman with huge bulla on left lung and diffuse fibrosis in other site, who ingested paraquat 10 months ago. After thoracoscopic removal of bulla, the patient survive without progression of pulmonary complication till now.

Primary pulmonary hemangiopericytoma is a rare, potentially malignant tumor and assumes more malignant course than that originated in the soft tissue. It can be asymtomatic until attaining a large size within the lung. We report a case of malignant hemangiopericytoma of the lung in a 29 year old man. It represented as a sharply demarcated, huge homogeneous opaque mass in the right upper lobe. The cytologic and histologic features were that of malignant hemangiopericytoma.
