Retrospective clinicopathologic analysis of 15 patients with the phyllodes tumors(PT) of the breast, diagnosed at SNUH over 6 years period, was done. By light microscopy, 8 cases were diagnosed as benign, and 7 cases were diagnosed as malignant. Mean ages o the patients were 37 and 34 years in malignant and benign, respectively. Most of those cases were presented with a palpable mass of the breast. None of the patients with malignant PT had distant metastasis, Local recurrences were experienced in 3 patients among the malignant PT, and one patient among the benign PT. One of 7 malignant PT was coexisted with simultaneous ipsilateral infiltrating duct carcinoma. The clinical course was not well correlated with pathologic features. The prognostic significances of several histopathologic parameters were assessed for possible correlation with local recurrence, metastasis and death; stromal cellularity, stromal cellular atypism, mitotic activity, tumor contour, necrosis, tumor size and heterologous stromal elements. Immunohistochemistry using antibody to vimentin, proliferating cell nuclear antigen(PCNA) and epidermal growth factor receptor(EGF-R) were analysed. In the 5 cases of benign PT, the stromal cells stained diffusely positive for vimentin and 3 cases of malignant tumors show similar staining for vimentin. The percentage of PCNA-positive cells were higher in the malignant PT than in the benign ones; they were 3.5% to 60% in malignancy, while they were less than 60% in all benign PT. The results of EGF-R staining were correlated with the histologic classification; only 2 cases out of 8 benign PT show diffusely positive staining of EGF-R in the cytoplasm, but 6 cases out of 7 malignant PT show positive findings.

Familial hemiplegic migraine(FHM) is an autosomal dominant subtype of migraine with aura, characterized by the occurrence of hemiplegia during the aura. Two subforms of FHM families exist; pure FHM in 80% and FHM families with cerebellar symptoms in 20%. Half of the known FHM families show genetic linkage to chromosome 19p13, and in these families FHM is caused by missense mutations in a neuronal P/Q type calcium channel alpha-1 subunit gene(CACNA1A gene). Linkages to 1q31 and 1q21-23 have also been established. Other families are linked neither to chromosome 19 nor 1. Clinical variabilities are partially associated with the various types of CACNA1A gene mutations. FHM is distinguished from more frequent migraine types by a clear, dominant inheritance pattern and the relative absense of other headache types. Further investigation of FHM will help to clarify the genetics of more common migraine. We describe a male patient with FHM with a brief review of the literature.

PURPOSE: This study was performed to find out the role of routine lumbar puncture in children presented with their first seizure with Fever. METHODS: This study included 220 children, over a 5 year period, from April 1999 to March 2003, who visited or were admitted at Dae Dong Hospital with their first febrile convulsion. Lumbar puncture was performed in all children. We analyzed their age, family history, type of seizure, duration of seizure, cause of fever, and the results of lumbar puncture. RESULTS: In the sex distribution, males(58.6%) outnumbered females(41.4%) and the ratio was 1.2:1. 81.7% of the patients had febrile convulsion from 6 months- to 3 years of age(P<0.05). 30.5% also had family history of febrile convulsion. The types of seizure were generalized tonic-clonic(72.7%), generalized tonic(17.7%), and generalized clonic(6.4 %). For the duration of seizure, 90.4% of the patients were estimated less than 15 minutes(P<0.05). The causes of fever were pharyngotonsilitis(40.5%), gastroenteritis(19.1 %), pneumonia or bronchitis(13.2%), meningitis(11%), otitis media, urinary tract infection, and exanthem subitum. However, 9.1% of the patients were diagnosed meningitis, with 18 of 20 patients under 3 years of age. CONCLUSION: In the first seizure with fever, lumbar puncture is a useful method for meningitis, especially under 3 years of age.

Immunohistochemical study for c-erbB-2 oncoprotein was performed on paraffin sections of 76 primary breast carcinomas to determine the relationship between expression of c-erbB-2 and various clinicopathological prognostic indicators, including the expression of epidermal growth factor receptor (EGFR). Positive reaction for c-erbB-2 oncoprotein revealed an intense red granular staining predominantly located at the tumor cell membrane, with some cells exhibiting a weak cytoplasmic staining as well. The epithelial cells of the normal lobule and duct showed a negative reaction. Positive reaction for EGFR revealed a granular staining in the cytoplasm and the cell membrane of the tumor cells. Some tumors showed a positive EGFR staining in the epithelial cells of normal duct and lobule. Twenty six of 76 cases (34.2%) of primary breast carcinomas revealed a positive reaction for c-erbB-2 oncoprotein, and 28 cases (36.8%) were positive for EGFR. Expression of c-erbB-2 oncoprotein and EGFR was evident in 37.7% and 40.6% of 69 classic invasive ductal carcinomas, respectively. None of the other histological types showed a positive reaction. Expression of c-erbB-2 oncoprotein was strongly associated with tumor size(p=0.0015), histologic grade(.p=0.0175), vascular invasion(p=0.0043), and lymph node metastasis(p=0.0024), but not with age at diagnosis(p=0.1836). No significant association was found between expression of c-erbB-2 oncoprotein and EGFR. Co-expression of c-erbB-2 oncoprotein and EGFR was also strongly associated with tumor size (p=0.0029). These results suggest that c-erbB-2 oncoprotein is biologically distinct from EGFR, and may be used as a prognostic indicator of breast carcinoma due to its strong association with various clinicopathological prognostic factors.

Clear cell sarcoma of tendon and aponeuroses is slow growing and painless. It occur chiefIy in young adults, predominates in women and is most common in the region of the foot and knee. It is intimately bound to tendons or aponeuroses and is composed of srnall nest or aggregates of round or fusiform, pale staining cells showing prominent nucleoli. And it is tend to recur and to resuIt in eventual development of metastatic growth after a protracted clinical ccurs. Herein, we report a case of clear cell sarcorna of tendon anu aponeuross of metatarsophalangeal joint area between 2nd and 3rd light of left foot. The patient, 50-year-old female had a slow groving, asymptomatic, slightly eevated, emooth surfaced and normal skin colored mass for 2 years. Histopatholcigic tindings in dermis revealed nests of atypical polygonal or monotonous cells. Each cell had vesicular or hyperchrornatic nucleus with prominent nucleoli, occcasionally mitotic figure and abundant eosinophilic cytoplasm. For. treatment, transmetatarsal amputation was done.

Journal of the Korean Neurological Association 1997;15(4):762-774
RATIONALE: Studies on ictal SPECT as a method of presurgical evaluation in neocortical epilepsy have been rare and inadequate. We evaluated the accuracy in the localization of epileptic foci with ictal SPECT in neocortical epilepsy and tried to find out the determining factors of its accuracy. METHODS: We performed ictal SPECT 66 times with 99m-Tc-HMPAO in 56 patients, who received video-EEG monitoring and had electroclinical features of neocortical epilepsy. Invasive monitoring was performed in 28 patients & epileptic surgery was done in 31. Their results were also used to help determine the location of epileptic foci. In 54 of 66 scans data about injection time and temporal relationship of HMPAO injection to the onset and secondary generalization of seizures were available. RESULTS: Frontal lobe epilepsy(FLE) was most common(35%) followed by lateral temporal lobe epilepsy(28%), occipital lobe epilepsy(11%), parietal lobe epilepsy(9%), and etc. Ictal SPECT demonstrated unilateral hyperperfusion in 53 of 66 scans (80.3 %) which were concordant with electroclinical lateralization in 48 of 53 (90.6 %). Localized hyperperfusion was evident in 42 of 66 scans (63.6 %) which were concordant with electroclinical localization in 33 of 42(78.6 %). Correctly localized hyperperfusion or correctly-lateralized but diffuse hyperperfusion were detected in 37 of 54 scans in which data about injection time were available. The mean injection time was 32.1 seconds. In 16 scans ictal SPECT showed no hyperperfusion or falsely localized/lateralized hyperperfusion. Their mean injection time was 41.6 seconds. The difference of injection time between two groups was not significant(p-value=0.07), but there was a tendency that the mean injection time of the former group was earlier than that of the latter group. We had chances to perform ictal SPECT repeatedly in 8 patients under the similar conditions. The fact that earlier injection improved the accuracy of ictal SPECT in 6 patients supports the importance of early injection. In 48 studies with ictal injection, only 11 scans gave no or incorrect information of the localization or lateralization of epileptic foci. But, in 6 studies with postictal injection, 5 scans was not helpful. The difference between two groups was statistically significant(p<0.05). The presence of focal lesion, the location of epileptic foci, or secondary generalization did not influence the accuracy of ictal SPECT. CONCLUSIONS: Our data suggest that ictal SPECT in neocortical epilepsy is useful in localization of epileptic foci. Whether injected ictally or postictally and the injection time from seizure onset seems to influence the accuracy of ictal SPECT in neocortical epilepsy.

Journal of the Korean Neurological Association 1997;15(4):754-761
PURPOSE: To evaluate the efficacy of vigabatrin and valproic acid add-on therapy in the treatment of uncontrolled partial-onset seizures through randomized active controlled parallel-group trial. METHODS: Criteria for entry included a requirement for three or more partial seizures per month despite the blood level of carbamazepine was within therapeutic range. During the 56-day baseline period, patients had at least 6 partial onset seizures. Vigabatrin or valproic acid were administered as the second drug in a randomized fashion. RESULTS: Forty one patients completed the trial(21 for vigabatrin, 20 for valproic acid). There is no statistically significant difference in age, age at onset, baseline seizure frequency, dose of carbamazepine, and serum level of carbamazepine between two groups. Two patients of vigabatrin-treated group and three patients of valproic acid treated group were dropped out because of side effects. The mean vigabatrin and valproic acid does were 2809 and 1490 mg, respectively. The percentage of patients achieving at least a 50% reduction in seizure frequency at the end of 8-week of add-on trial was 62% among vigabatrin-treated patients and was 50% for patients who received valproic acid(not statistically different). There was no significant difference in seizure reduction, percent seizure reduction, and truncated percent seizure reduction between two groups. The side effects were mild and transient neurotoxic symptoms in the patients who completed the trial(5 patients for vigabatrin, 10 patients for valproic acid). CONCLUSIONS: This trial indicates that vigabatrin and valproic acid are safe and effective in the treatment of intractable partial-onset seizures. The efficacy of vigabatrin as a new add-on antiepileptic drug is comparable to the previous valproic acid carbamazepine combination in the sense of seizure reduction and maybe even superior to that in the consideration of side effects

We evaluated MR imaging of spondylolytic spondylolisthesis degenerative spondylolisthesis and retrolisthesis in 14, 9 and 20 patients respectively. Sagittal and axial spin echo and gradient echo images were obtained with 25-30cm FOV and 5mm/0.5mm thickness/gap by using spine surface coil. Sagittal images showed defects of pars interarticularis just inside of the pedicles of spines in all the cases of spondylolytic spondylolisthesis with relatively variable signal intensity. Displaced vertebrae were commonly observed at L5 (8/14) in spondylolytic spondylolisthesis, at L4 (5/9) in degenerative spondylolisthesis and at variable locations in retrolisthesis. The mean length of displacement of vertebrae in spondylolytic spondylolisthesis was about 7mm and less displacement was onserved in degenerative spondylolisthesis and retrolisthesis. Seven, four and six cases of pseudobulging of disk at displaced level were observed in cases of spondylolytic spondylolisthesis, degenerative spondylolisthesis and retrolisthesis respectively. Seven, five and 14 cases of true disk lesions were onserved in cases of spondylolytic spondylolisthesis, degenertive spondylolisthesis and retrolisthesis respectively. Grade II neural foraminal stenoses (obliteration of one half epidural fat of neural foramen) were commonly (8/14) seen in spondylolytic spondylolisthesis, however the other two types showed less severe neural foraminal stenosis. In conclusion, MR imaging is a highly accurate method for the diagnosis and evaluation of spondylolisthesis and associated lesions of spine and disks.
