Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

Recently we experienced a case of embryonal rhabdomyosarcoma of the bladder in a 38 years-old female. She complained of total painless gross hematuria and diagnosis was made by cystoscopy and TUR biopsy. Partial cystectomy and pelvic lymph node dissection performed on July 1989, and then she received the chemotherapeutic agents under the diagnosis of Intergroup Rhabdomyosarcoma Study Group I, the post-operative 8 months, she is in good condition without recurrence of tumor.

PURPOSE: To correlate radiologic findings with clinical findings in patients with a mosaic patten of lungattenuation, as seen on thin-section CT. MATERIALS AND METHODS: Thirty-one cases in which a mosaic pattern oflung attenuation was detected on combined expiratory and inspiratory scans of thin-section CT were retrospectivelyanalyzed. Cases involving infiltrative lung disease were excluded. Both thin-section CT and clinical findings wereanalyzed and the relationship between the extent of the area of hyperlucency -as seen on expiratory scan- andphysiologic parameters was evaluated. The subjects were 10 men and 21 women ranged in age from 25 to 76 (mean 50)years. RESULT: Twenty-nine patients with small airway disease, [chronic bronchitis and/or bronchiolitis(n=11),bronchiectasis(n=8), bronchial asthma(n=8), mycoplasmic pneumonitis(n=1) and hypersensitive pneumonitis(n=1),] andtwo patients with pulmonary vascular disease, [chronic pulmonary thromboembolism(n=1) and stenosis of the leftupper pulmonary artery(n=1)] were included in our study. Commonly associated thin-section CT findings in the casesinvolving small airway disease(n=29) were bronchial wall thickening(n=25), nodular opacity(n=25), bronchial andbronchiolar dilatation(n=20) and small branching opacity(n=16). These findings were not observed in two patientswith pulmonary vascular disease, though bronchial wall thickening was seen in the patient with chronic pulmonarythromboembolism. At expiratory scan level, there was statistical correlation between FEV1/FVC and the number ofpulmonary segments(r= 0.982, p<0.05), but no correlation between FEV1/FVC and the percentage area ofhyperlucency(r=0.803, p>0.05). CONCLUSION: The mosaic pattern of lung attenuation seen on thin-section CT isindicative of various diseases, involving small airways such as bronchiolitis, bronchitis, bronchiectasis andbronchial asthma, and vascular lung disease. Bronchial wall thickening and nodular opacity can be associated withsmall airway diseases.

BACKGROUND: Scabies is an ectoparasite caused by the mite Sarcoptes scabiei var. hominis, an obligate human parasite. Although its incidence has been decreasing, it is not a rare dermatologic disease and is difficult to diagnosis. OBJECTIVE: To evaluate the clinical characteristics of scabies patients and find out etiologic factors in transmission. METHODS: Two hundred and ninety-five patients who were diagnosed with scabies at the Dermatologic Department, Myongji Hospital, Goyang city, Korea were enrolled. Medical records were evaluated in a retrospective manner. RESULTS: We studied 295 scabies patients who were diagnosed by the mineral oil test or skin biopsy. The mean age of the patients was 58.2 (male: 56.7/female: 61.2), and 74% of patients were over 60 years. There was seasonal variation in occurrence, and scabies was found to be most common in winter. The majority of suspected routes of infection were transmission through convalescent hospitals (38.1%) and caregivers (15.2%). Nosocomial infection and communal living were the major causes. 73.8% of scabies patients had underlying medical disease, such as hypertension (32.2%) and dementia (11.9%). CONCLUSION: Currently, scabies prevalence is still increasing in Goyang city, because of the increased number of convalescent hospitals.

OBJECTIVE: To investigate the peak torque of shoulder according to the size of the rotator cuff tear. METHOD: With 26 patients of unilateral rotator cuff tear, we measured the concentric isokinetic peak torque of shoulder, using Con-Trex isokinetic dynamometer (CMV AG, Deubendorf, Switzerland). We measured flexion, extension, abduction, adduction, external rotation, and internal rotation torques and calculated the peak toque ratio of flexion/ extension, abduction/adduction and external rotation/internal rotation. Before the test, we injected 1% lidocaine to the subacromial bursa to minimize the error that can be caused by pain. The difference of peak torque according to the size of tear was compared. RESULTS: Comparing the peak torque between affected and sound side, significant difference in flexion, extension, abduction, adduction, internal rotation, and external rotation were shown, but there were no difference in peak torque's ratio in flexion/extension, abduction/adduction, and internal rotation/external rotation. When we compared the peak torque according to the tear size, it didn't show significant difference and also there were no difference of peak torque's ratio in flexion/extension, abduction/adduction, internal rotation/external rotation. CONCLUSION: When we measured the shoulder's strength of rotator cuff tear, peak torque decreased in all motion. But the peak torque's loss and peak torque's ratio is not related with size of tear.

Chronic necrotizing pulmonary aspergillosis (CNPA) is an unusual form of pulmonary aspergillosis arising in the setting of mildly immune compromised state or altered local defense system. CNPA rarely shows histological findings mimicking bronchocentric granulomatosis (BCG), which is characterized by peribronchiolar granulomatous destruction. We describe a case representing CNPA with elements of BCG. A-64 year-old woman was admitted because of atypical pneumonia with multi-focal variable sized consolidations and cavitary lesions on high-resolution computed tomography (HRCT). The open lung biopsy specimen showed large areas of necrotizing pneumonia with some scattered aspergillus hyphae within the lung parenchyma. Some terminal bronchioles were found to be destroyed and were replaced by peribronchiolar granulomatous inflammation. There was no evidence of angioinvasion by aspergillus or aspergillous emboli. Despite vigorous antifungal agent and steroid treatment, she died of acute airway obstruction by bronchial casts on the thirty-fourth hospital day.

Angiomyolipoma is a common tumor of the kidney but has rarely been found in the mediastinum. We report a case of angiomyolipoma of the posterior mediastinum in a 62-year-old woman. She experienced exertional dyspnea and intermittent cough at admission. Computed tomography indicated a tumor located at the left paravertebral and upper posterior mediastinum and MRI imaging demonstrated a mass with low signal intensity in T1-weighted image at T4-5 level. Thoracotomy was done for surgical removal of the tumor and histologic examination revealed a mesenchymal tumor composed of mature fat, capillaries and smooth muscle fibers. The tumor was immunohistochemically positive for CD34 and factor-VIII (for vascular component) smooth muscle actin (for smooth muscle component) and S-100 protein (for fat component). There have been four case reports about mediastinal angiomyolipoma, namely three Japanese cases and one French case. It is suggested that angiomyolipoma could be considered for the differential diagnosis of mediastinal tumors.

PURPOSE: To determine the influence of osteoporosis on the results of percutaneous K-wire fixation for distal radius fractures. MATERIALS AND METHODS: Between March 2007 and February 2011, Fifty seven patients who underwent fixative surgery with K-wires after closed reduction and those available for follow-up for at least 6 months were reviewed. They were divided into the two groups of T score -3 or more (group 1) and T score less than -3 (group 2). These groups were compared by the range of motion of the wrist and Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiologic evaluations consisting of radial length, radial inclination and volar tilt were compared. In group 1 with 34 cases, the average age was 65.4 years (50 to 78 years) and T score was -1.97 (-0.1 to -2.93). In group 2 with 23 cases, the average age was 74 years (54 to 89 years) and T score was -4.11 (-3.1 to -6.97). RESULTS: There was no statistical difference between group 1 and group 2 in terms of range of motion, DASH score and radiologic evaluations. CONCLUSION: In the case of no volar side cortical comminution, percutaneous K-wire fixation can be applied for the treatment of distal radius fracture with osteoporosis.
