Angiocentric T-cell lymphomas have been described as a distinctive clinicopathologic entity in the spectrum of peripheral T-cell lymphomas, with a prominent invasion of blood vessels by lymphomatous cells. In these conditions, the presence of Epstein-Barr virus (EBV) genomes has been demonstrated, suggesting that EBV might play a major role in their cause. Herein, we report a case of cutaneous angiocentric T cell lymphoma associated with the EBV. The patient was diagnosed with nasal angiocentric T cell lymphoma 5 months ago, and treated with cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) combination chemotherapy. After three cycles of CHOP, skin lesions developed. A skin biopsy specimen showed an angiocentric and angioinvasive infiltrate containing some atypical lymphocytes. EBV encoded RNA (EBER) was demonstrated in lesional skin by in situ hybridization.

Subcutaneous panniculitic T-cell lymphoma(SPTCL) is a rare subtype of peripheral T-cell lymphoma that clinically and histologically mimics benign panniculitis. SPTCL is characterized by subcutaneous nodules on the extremities and trunk. It has a tendency to occur mainly in female adults with eosinophilia, pruritus or hemophagocytic syndromes. Histopathologically, typical lesions of SPTCL show moderate to dense lymphocytic infiltrates in the subcutaneous fat, primarily involving the lobules. Early lesions may show only focal lymphocytic atypia: later lesions display karyorrhexis, necrosis and cytophagia. A 34-year-old woman presented with multiple, recurrent, tender subcutaneous nodules on the abdomen and extremities which she had had for 13 years. There was no hepatosplenomegaly or lymphadenopathy. Skin biopsy specimens revealed atypical small and large lymphocytic infiltrations in the subcutaneous tissue. Occasionally, histiocytes contained erythrocytes and lymphocytes in their cytoplasm. Immunohistochemical staining showed positive reactions to CD45RO and CD43. Negative reactions were seen to CD20, Leu-7 and lysozyme antigen. On the basis of the clinical & histological findings, we established the diagnosis of SPTCL.

BACKGROUND: The apnea test is an essential component in the clinical determination of brain death, however it may incur a significant risk of complications such as hypotension, hypoxia and even cardiac arrest. We analyzed the risk factors associated with a failed apnea test during brain death assessment in order to predict and avoid these adverse events. METHODS: Medical records on apnea tests performed for brain-dead donors at our institution between January 2009 and January 2016 were retrospectively reviewed. Age, gender, etiology of brain death, use of catecholamines and results of arterial blood gas analysis (ABGA), systolic/diastolic blood pressure (SBP/DBP), mean arterial pressure and central venous pressure prior to apnea test initiation were collected as variables. A-a gradient and P(aO2)/F(iO2) were calculated for more precise assessment of the respiratory system. In total, 267 cases were divided into two groups based on those who completed the apnea test and those who failed the test. RESULTS: 13 cases failed the apnea test. Among them, seven cases failed due to severe hypotension (SBP < 60 mmHg) and the others failed due to refractory hypoxia. In terms of hemodynamic state, SBP was significantly higher in the completed test group than the failed group (126.5 ± 23.9 vs. 103 ± 15.2, respectively; p = 0.001). In ABGA, the completed test group showed significantly higher P(aO2)/F(iO2) (313.6 ± 229.8 vs. 141.5 ± 131.0, respectively; p = 0.008) and a lower A-a gradient (278.2 ± 209.5 vs. 506.2 ± 173.1, respectively; p = 0.000). In multivariable analysis, low SBP (p = 0.003) and high A-a gradient (p = 0.044) were independent risk factors associated with a failed apnea test. CONCLUSIONS: Although the unexpected adverse events during the apnea test for brain death determination do not occur frequently, they can be fatal. If a brain-dead patient has low SBP and a high A-a gradient, clinicians should pay more attention and prepare for potential complications prior to the apnea test.

An unusual case of papillary carcinoma of the thyroid revealing numerous multinucleated giant cells in the aspiration biopsy cytology is reported. Papillary carcinoma is the most common malignant neoplasm of the thyroid and is frequently diagnosed by aspiration biopsy cytology. Recently, we experienced a case of papillary carcinoma with many multinucleated giant cells in a 55-year-old woman. The cytologic features are described.

PURPOSE: The purpose of the study was to explore factors influencing turnover intention of new graduate nurses according to length of services. METHODS: From May to July, 2017, a survey was conducted among 220 nurses working in four hospitals. Inclusion criteria were new graduate nurses who had careers of less than 16 months. Data were collected on organizational socialization, support in work place, job stress, and turnover intention. RESULTS: Satisfaction with current work department, job satisfaction, organizational commitment, and job stress were significant factors influencing turnover intention of new nurses with less than six months experience. However, in case of nurses with seven to 15 months experience, only organizational commitment influenced turnover intention. CONCLUSIONS: These findings indicate that the factors influencing turnover intention are different according to the length of time the new graduate nurses have worked. To reduce the turnover intention of new nurses, it is necessary to differentiate human resource management approaches according to length of employment. The study results could be useful evidence for developing strategies to reduce turnover in new nurses.

PURPOSE: To evaluate the usefulness, patterns and appearances of false positive lesions, and technical problems of CTAP(CT Arterioportography). MATERIALS AND METHODS: CTAP was done in 45 patients in whom hepatic lesions were suggested on other radiologic studies. CTAP findings were compared with the informations obtained by operations, biopsies, and follow-up imagings. Additional findings, which were not detected in other radiologic studies, false positive manifestations, and technical errors were analyzed. RESULTS: CTAP detected 51 additional hepatic lesions which are not detected in other imaging studies. Of the 51 lesions, ten were true positive hepatic tumors, 2 were inflammatory lesions and 39 were false positive .lesions. False positive lesions included perfusion defects of periportal and perifissural areas, subcapsular perfusion defects and nonlobar, nonsegmental geographic perfusion defects. In 2 cases, CTAP aided in deciding the surgical strategy. On the other hand, there were 4 cases causing interpretational confusion and 6 cases of improper imaging due to technical errors. CONCLUSION: CTAP was valuable in detection of additional hepatic cancer lesion as well as in making the treatment plan. However, since many false positive lesions and improper imaging due to technical error occur during the examination, the understanding of such problems is essential for correct interpretation of CTAP.
