Juvenile granulosa cell tumor is rare but one of the common congenital testicular neoplasms. Although histological features are typical of its ovarian counterpart, testicular juvenile granulosa cell tumor has a distinctly different clinical presentation. We report a case of juvenile granulosa cell tumor arising in the cryptochid testis of a 4-day-old newborn. A 6 5 5 cm sized multilocular cyst containing thick, mucinous fluid was found in the peritoneal cavity. The external surface of the cyst was smooth and the septae were relatively thin. The cyst consisted of numerous mucin-filled, cystic follicles lined by cells having vacuolated cytoplasm and round to oval dark nuclei without grooves. Cells resembling granulosa cells of an ovarian follicle were also observed in the intervening stroma forming irregular solid nests.

PURPOSE: To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer. MATERIALS AND METHODS: Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the in-house self respiration monitoring (SRM) system was used for visual feedback. For each scan, treatment plans were generated and dosimetric parameters from DIBH and EIBH plans were compared to those of FB plans. RESULTS: All patients completed CT scans with different breathing maneuvers. When compared with FB plans, DIBH plans demonstrated significant reductions in irradiated heart volume and the heart V25, with the relative reduction of 71% and 70%, respectively (p < 0.001). EIBH plans also resulted in significantly smaller irradiated heart volume and lower heart V25 than FB plans, with the relative reduction of 39% and 37%, respectively (p = 0.002). Despite of significant expansion of lung volume using inspiration breath-hold, there were no significant differences in left lung V25 among the three plans. CONCLUSION: In comparison with FB, both DIBH and EIBH plans demonstrated a significant reduction of radiation dose to the heart. In the training course, SRM system was useful and effective in terms of positional reproducibility and patient compliance.

Elastofibroma is a rare disease which presents as a slowly-growing, solid, ill-defined fibroelastic mass occuring almost exclusively in elderly women and arising mainly from the connective tissue between the lower part of the scapula and chest wall. Of the 270 cases of elastofibroma which have been reported, 170 cases had developed in Japanese patients. Despite the fact that there have been only two case reports in Korea, there might be a higher prevalence of elastofibroma in Korea than expected because of geographical similarity. We experienced a case of elastofibroma occurring in a 56-year-old man. To our knowledge, this is the first case report of elastofibroma in Korean dermatologic of literature.

BACKGROUND: Glomus tumor is a benign neoplasm derived from the normal glomus body. This tumor includes the following types; solitary, multiple, proliferating, and acral arteriovenous. Histologically, it was subdivided into solid type, glomangioma, and glomangiomyoma. Its malignant counterpart - glomangiosarcoma - was reported. OBJECTIVES: The purposes of this study were aimed to evaluate the clinical and pathologic presentations of glomus tumor. METHODS: A total of 17 patients who have been diagnosed with glomus tumor by histopathologic examination were reviewed. RESULTS: Male patients were ten and female patients were seven. The age of the onset of glomus tumor varied from birth to 61 years. The location of tumors were as follows: arm (7 cases), finger (6 cases), back (2 cases), leg (1 case), foot (1 case). The digit was the most common site for female patients. Clinical manifestations showed solitary bluish papule (6 cases), subcutaneous nodule (5 cases), nail discoloration (3 cases), nail dystrophy (1 case), bluish plaque (1 case). One patient had no specific lesion but tenderness. The most characteristic symptom was pain in 15 (88.2%) of the 17 patients, and the other two patients had no symptom. Two asymptomatic lesions were located on the forearm and histopathologically showed glomangioma. Histopathologically, 13 (76.5%) of the 17 patients classified as solid type, and 4 (23.5%) the glomangioma variety. CONCLUSION: Glomus tumors were most commonly seen as a painful nodule on the upper extremity and especially female patients showed predilection for subungual location. We speculate that multiple, mild symptomatic lesions might be a tendency to be glomangioma.

A 13-year old boy was seen for progressive enlargement of a right scrotal mass that had been present since early childhood. Scrotal mass was excised and consisted of a well demarcated multinodular cystic soft mass. Pathology was characteristic of cavernous lymphangioma. Lymphangiomas are benign tumors of congenital origin, occurring about 95% of the lesion at neck and axilla. Their scrotal location is quite uncommon. Treatment consists of surgical excision. Unless completely removed, recurrences are common.

Takayasu's arteritis(TA) is a nonspecific areritis of unknown etiology affecting segmentally the aorta and its main branches, which result in stenosis, occlusion or aneurysm of involved arteries. The clinical manifestations present with a variety of symptoms such as headache, dyspnea on exertion, pain and weakness of extremities, pulse deficit, and hypertension according to involves arteries. Usually it can be managed by medical or surgical treatment, and recently by percutaneous transluminal balloon angioplasty. The type III classified by Lupi-Herrena and associates is the most frequent variety of TA. However the case of type III involving both subclavin arteries and both renal arteries has rarely been reported. We experienced a case of TA involving both subcalvian arteries, and both renal arteries presented with paroxysmal hypertension and right flank pain, in which the stenosis of both subclavian arteries were managed by percutaneous transluminal balloon angioplasty and the stenosis and occlusion of both renal arteries were successfully managed by aorto-renal bypass surgery with autogenous right iliac artery and synthetic vessel(Gortex). The patient was discharged uneventfully.

Clinical types of glomus tumors can be divided into the more common solitary type and the rare multiple types. The latters are subdivided into disseminated, regional, and congenital plaquelike type. We report a 25 year old man with a red to blue colored soft nodular plaques on the back. The lesions were soft reddish patches since birth and gradually enlarged. These were gradually changed to blue colored soft nodular plaques with mild tenderness. The histologic findings were compatible with the glomus tumor.

The angiotensin-converting enzyme (ACE) gene DD homozygote has been suggested to be a significant risk factor for the progression of diabetic nephropathy. We analyzed clinical parameters and ACE genotype distribution between type 2 diabetic patients at the extremes of renal risk, i.e. an end-stage renal failure (ESRF) group (n = 103, group 1) who were on dialysis therapy due to progression of diabetic nephropathy, and a no progression group (n = 88, group 2) who had maintained normal renal function and normoalbuminuria for more than 15 years. There were no significant differences in age, sex, body mass index, HbA1c level, or lipid profiles between the two groups (p > 0.05). Group 1 had a significantly higher prevalence of hypertension [group 1: 82.5% (85/103) vs. group 2: 50.0% (44/88), p < 0.05] and diabetic retinopathy [group 1: 103/103 (100%) vs. group 2: 28/88 (31.8%), p < 0.05] than group 2. Daily urinary albumin excretion was also higher in group 1 than in group 2 [group 1: 2873 +/- 2176 mg/day vs. 12 +/- 7 g/day, p < 0.05]. The frequencies of the DD, ID, and II genotypes of the ACE gene in group 1 and group 2 were 26.2%, 47.6%, and 26.2%, and 7.9%, 57.9%, and 34.2%, respectively. The ACE genotype frequencies between the two groups were significantly different according to a chi-square test with Bonferroni's correction (p = 0.004). The presence of the DD genotype increased the risk of ESRF 4.286-fold compared to the II genotype [odds ratio 4.286, 95% CI 1.60- 11.42, p = 0.005]. The frequency of the D-allele was higher in both male and female patients in group 1 compared to group 2, but reached statistical significance only in males [male, group 1: 50.8% vs. group 2: 35.0%, p = 0.018, female, group 1: 48.8% vs. group 2: 39.5%, p = 0.231]. This study, although limited by sample size, showed that type 2 diabetic ESRF patients more frequently expressed the DD genotype. These findings may substantiate the previously noted relationship between the ACE DD genotype and the progression of diabetic nephropathy in Korean type 2 diabetic patients.
