Extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue (MALT lymphoma) is a low-grade B-cell lymphoma that presents with an indolent clinicopathologic nature. Although this tumor can occur in various sites, including the gastrointestinal, skin, salivary gland and ocular adnexa, radiation therapy shows high local control in that disease. We report a case of recurrent MALT lymphoma presenting a huge cheek mass after radiotherapy on ocular adnexal lymphomas. An 65-year-old man had a history of treatments on MALT lymphomas of ocular adnexa came again with a huge cheek mass, not recurred and not originated from salivary gland, skin, other related mucosa tissues. He got excisional biopsy and was confirmed immunohistochemically as MALT lymphoma. After diagnosis, he was sent urgently to a radiotherapist for further treatment. He responded well to added radiotherapy with 36 Gy dose and has remained well at 6 months after his initial presentation.

Juvenile nasophayngeal angiofibroma (JNA) is a histologically benign but highly vascular, agressively expansile lesion that occurs exclusively in prepubescent or pubescent males. Traditional treatmemt strategy of JNA has included open surgical approaches for majority of tumors. However, radiosurgery has been rarely applied for juvenile nasopharyngeal angiofibroma (JNA) and cumulative reports are lacking. The authors report a case of successful treatment of postoperative residual JNA with gamma knife radiosurgery.

PURPOSE: This study analyzed the correlation between grade point average (GPA) of medical school and the score of Korean Medical Licensing Examination (KMLE). METHODS: This study based on the results of 67th KMLE applicants who graduated from a college of medicine in 2003. We also gathered data of these applicants from the college of medicine: gender, age, type of entrance, GPA of basic medicine, clinical medicine, clinical clerkships and final test scores. We analyzed whether there was discrimination between achievement of KMLE passed and that of KMLE failed, which of variables affected the results of KMLE. RESULTS: 173 applicants passed KMLE among 189. There were significant correlations between basic medicine, clinical medicine, final test score and the score of KMLE (respective p-value; < 0.0001). There were also significant differences of GPA between KMLE passed applicants and failed. Final test scores were the most correlated with those of KMLE. If the GPA of 2nd grade was below 2.5 and the GPA of 3rd year grade was below 2.3, they was a high-risk group for failing KMLE (sensitivity 100%, specificity 90%). CONCLUSION: There were significant correlations between the GPA of medical school and the score of KMLE, and significant differences between KMLE passed applicants and failed. A high-risk group of failing KMLE was the students that the GPA of 2nd grade was below 2.5 and the GPA of 3rd grade was below 2.3.

OBJECTIVES: Odors used in an odor identification test should be familiar to the subject, but there are some unfamiliar distracters in Korean version of Sniffin' stick (KVSS) II identification test. In this study, we used the results of the original version of KVSS II identification to modify the KVSS II identification test. METHODS: Eighty-three participants took an original version of KVSS II identification test and a visual analogue scale of subjective odor function. KVSS II identification which has 16 items was performed to choose one out of four odors items. And visual analogue scale was checked from 0 to 10 points of their subjective olfactory function. Two weeks later they took the modified version of KVSS II identification test. Hyposmic or anosmic patients were excluded. RESULTS: The mean score of the original version of KVSS II identification and modified version of KVSS II identification were 11.3 and 12.5, respectively (P<0.05). The KVSS II identification test and subjective olfactory function were positively correlated (r=0.247, P<0.05), as were the modified KVSS II identification test and subjective olfactory function (r=0.329, P<0.05). CONCLUSION: After modification of distracters, KVSS II identification test appears to be suited for assessment of olfactory function.

PURPOSE: To review the sonographic findings of various diseases showing architectural distortion depicted under mammography. MATERIALS AND METHODS: We collected and reviewed architectural distortions observed under mammography at our health institution between 1 March 2004, and 28 February 2007. We collected 23 cases of sonographically-detected mammographic architectural distortions that confirmed lesions after surgical resection. The sonographic findings of mammographic architectural distortion were analyzed by use of the BI-RADS lexicon for shape, margin, lesion boundary, echo pattern, posterior acoustic feature and orientation. RESULTS: There were variable diseases that showed architectural distortion depicted under mammography. Fibrocystic disease was the most common presentation (n = 6), followed by adenosis (n = 2), stromal fibrosis (n = 2), radial scar (n = 3), usual ductal hyperplasia (n = 1), atypical ductal hyperplasia (n = 1) and mild fibrosis with microcalcification (n = 1). Malignant lesions such as ductal carcinoma in situ (DCIS) (n = 2), lobular carcinoma in situ (LCIS) (n = 2), invasive ductal carcinoma (n = 2) and invasive lobular carcinoma (n = 1) were observed. As ovserved by sonography, shape was divided as irregular (n = 22) and round (n = 1). Margin was divided as circumscribed (n = 1), indistinct (n = 7), angular (n = 1), microlobulated (n = 1) and sipculated (n = 13). Lesion boundary was divided as abrupt interface (n = 11) and echogenic halo (n = 12). Echo pattern was divided as hypoechoic (n = 20), anechoic (n = 1), hyperechoic (n = 1) and isoechoic (n = 1). Posterior acoustic feature was divided as posterior acoustic feature (n = 7), posterior acoustic shadow (n = 15) and complex posterior acoustic feature (n = 1). Orientation was divided as parallel (n = 12) and not parallel (n = 11). There were no differential sonographic findings between benign and malignant lesions. CONCLUSION: This study presented various sonographic findings of mammographic architectural distortion and that it is difficult to differentiate between benign and malignant lesions depicted under sonography. Pathological confirmation is needed for mammographic architectural distortion.

Pulmonary nodular lymphoid hyperplasia (NLH) is a term first suggested by Kradin and Mark to describe one or more pulmonary nodules or localized lung infiltrates consisting of reactive lymphoid proliferation. To date, there have been only a few cases of pulmonary NLH reported associated with autoimmune disorders. There is no case of NLH associated with Sj?gren's syndrome from Korea in the medical literature. A 56-year-old woman was referred to our hospital with cough productive of sputum and chest tightness. The Computed tomography scans of the chest revealed multiple and well-defined peribronchiolar nodular opacities. A video assisted thoracoscopic surgery (VATS) biopsy was performed and the nodular opacity in the lung parenchyma was pathologically confirmed as NLH. Through meticulous review of patient's record, we found that she had been suffering from dry eye and dry mouth. The symptoms suggested Sj?gren's syndrome, which was confirmed by specific laboratory tests including the Schirmer test, anti-nuclear antibody and anti-Ro/La antibody. The patient is followed regularly and has no further progression of symptoms.

PURPOSE: Aberrant methylation of CpG islands in gene promoters has been considered as a common mechanism for suppressing gene expression in cells. Hypermethylation of CpG islands in promoters is associated with silencing of transcription in various tumor suppressor genes and recent studies identified a CpG island methylator phenotype (CIMP) suggesting common methylation defect in cancer cells. For breast cancer, several genes were previously reported to be hypermethylated, but it is unclear whether the CIMP status is associated with any clinicopathological characteristics of breast cancer. In this study, we investigated the methylation patterns of several genes such as p16(INK4a), O(6)-methyguanine-DNA methyltransferase (MGMT), Death associated protein kinase (DAPK), E-cadherin, hMLH1, and four loci such as Methylation in tumor (MINT: MINT1, MINT2, MINT25, MINT31) and analyzed the correlation with clinical features. METHODS: 85 patients who underwent curative surgery for breast cancer were studied retrospectively using their paraffin-embedded tissues and medical records. Immunohistochemical staining were performed according to their hormone receptors. DNA extraction, sodium bisulfite modification and methylation specific PCR (MSP-PCR) were performed with some modifications. RESULTS: The rates of E-cadherin and MINT 31 methylation in cancer tissue were significantly higher than those of normal tissues (P<0.05). There was no statistical correlation between methylation status of each suppressor genes and hormone receptor except DAPK methylation with progesteron receptor. The rate of E-cadherin methylation was significantly high in stage II (P=0.010). For 5-year survival and disease-free survival rate, the group with methylated MINT1 and MINT25 had significantly better outcome than unmethylated group (P<0.05). There was no statistical significance between CIMP status and other prognostic factors such as hormone receptor and stage (P=0.885). But, CIMP-High group was significantly lower than CIMP-Low group in 5-year survival (P=0.001) and disease-free survival rate (P=0.024). CONCLUSION: The methylation of E-cadherin and some MINT loci seems closely related to tumorigenesis in breast cancer and CIMP status have some value as a prognostic indicator after surgery in breast cancer but more large scale study will be needed.

Hypertrophic cardiomyopathy (HCM) is associated with an increased incidence of Wolff–Parkinson–White (WPW) syndrome and atrial fibrillation. However, a delta-like wide QRS can be observed in the hypertrophied myocardium. When considering the rarity of the paraseptal bypass tract (BT), the normal QRS axis suggests a higher possibility of HCM origin. Otherwise, there is no known electrocardiographic clue indicating a wide QRS differentiation between HCM and WPW syndrome. Moreover, the atriofascicular, nodofascicular/ventricular or fasciculoventricular BT should be differentiated. In this case, atrioventricular conduction system incidental injury revealed a wide QRS origin from the HCM, but this method should be avoided except in some selected cases.
