In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentally during screening work up. The mammographic findings were bilateral, hyperdense, spiculated masses, with occasional microcalcification, and at sonography, markedly hypoechoic, spiculated solid masses, located near the pectoralis muscle and partly extending into it, were observed. These radiologic findings mimicked malignancy.

Trichoblastoma includes all benign follicular germinative cell tumors in skin. We presented a case of trichoblastoma which occurred on the scalp as a large pedunculated tumor. The tumor was composed of lobular aggregations of basaloid epithelial cells and numerous primitive papillary mesenchymal bodies. Stromal retraction was observed between the stroma adjacent to epithelial nests and surrounding normal dermis. Focal connection to the overlying epidermis was observed. The classification and terminology for the benign neoplasms with follicular differentiation was discussed.

Objective:
We investigated the agreement between anti-Müllerian hormone (AMH) levels measured with revised Gen II (rev-Gen II) and automated AMH (Access) assays and evaluated the reproducibility of each method under various blood/serum storage conditions.
Methods:
AMH levels in blood samples from 74 volunteers were measured by rev-Gen II and Access assays under various conditions: immediate serum separation and AMH measurement (fresh control); serum stored at –20 °C and AMH measured after 48 hours, 1 week, and 2 years; serum stored at 0 to 4 °C and AMH measured after 48 hours and 1 week; and blood kept at room temperature and delayed serum separation after 48 hours and 1 week, with immediate AMH measurement.
Results:
In fresh controls, all rev-Gen II-AMH values were higher than comparable Access-AMH values (difference, 8.3% to 19.7%). AMH levels measured with the two methods were strongly correlated for all sample conditions (r=0.977 to 0.995, all p<0.001). For sera stored at –20 °C or 0 to 4 °C for 48 hours, Access-AMH values were comparable to control measurements, but rev-Gen II-AMH values were significantly lower. AMH levels in sera stored at –20 °C or 0 to 4 °C for 1 week were significantly lower than in fresh controls, irrespective of method. Across methods, long-term storage at –20 °C for 2 years yielded AMH measurements significantly higher than control values. When serum separation was delayed, rev-Gen II-AMH values were significantly lower than control measurements, but Access-AMH values varied.
Conclusion
The rev-Gen II and Access-AMH assays showed varying reproducibility across blood/serum storage conditions, but automated Access yielded superior stability to rev-Gen II.

Wegener's granulomatosis (WG) is a systemic necrotizing vasculitis belonging to the small- to medium-sized vessel. A 46-year-old male presented with erythematous hard plaque on chest, calf and multiple subcutaneous nodules on buttock, upper arm. Incisional biopsy was done and the histopathologic finding revealed the features of necrotizing vasculitis with focal granulomatous inflammation in subcutaneous tissue. PNS MRI showed abnormal meningeal enhancement and lung HRCT imaging showed mild infiltration. Inspite of severe systemic involvement, serum tests about ANCA showed negative result. He was treated with systemic corticosteroid and cyclophosphamide pulse therapy. Initially his condition showed improvement but later the disease worsened.

We carried out an immunohistochemical study and DNA analysis of 14 surgical specimens of primary bladder carcinoma and paired sample of normal bladder mucosa to evaluate p53 over expression, point mutation by polymerase chain reaction single-strand conformation polymorphism analysis(PCR-SSCP). The immunohistochemical study demonstrated immunoreactivity for p53 protein in ten cases out of 14(71%) with monoclonal antibody (NCL-p53-DO-7, Novocastra Lab. UK). Mobility shifts were detected by PCR-SSCP in p53 gene exons 4-8 in six cases out of 14(42.9%). p53 gene mutations were observed in invasive cases(85.7%) and superficial cases (50%) by immunohistochemistry. Correlation was not observed between the presence of p53 gene mutations and the histological differentiation and invasiveness of the cancer. Considering frequent p53 alterations in invasive cases, it will be necessary to reevaluate p53 alterations in bladder cancer and the correlation to the prognosis in bladder cancer.

Fibrotic lesions occurring in the corpus cavernosum are usually cases of Peyronie's disease that originate from the tunica albuginea, or they are the fibrotic result of inflammatory processes. The lesion involving the corpus cavernosum, but not tunica albuginea is rare. We present here a case of fibrotic nodule arising in the corpus cavernosum with the sonographic and magnetic resonance imaging features. A 38-year-old man complained a small nodular mass in the left corpus cavernosum at the level of penoscrotal junction without abnormal curvature of the organ. We performed ultrasonography and magnetic resonance imaging to determine exactly what the lesion was. The lesion was removed and it was pathologically found to be a localized fibrotic nodule of the corpus cavernosum with some narrow-channeled vascular structures.

An 8-year-old boy presented with abdominal pain and poor oral intake for two months. Serum amylase and lipase levels were elevated. CT of the abdomen and chest X-ray showed two pseudocysts at the pancreatic uncinate process, pancreatitis with a parenchymal defect, a large amount of ascites, and a right pleural effusion. MR cholangiography and endoscopic retrograde cholangiopanreaticography revealed a pancreatic duct disruption. The patient was successfully treated with a chest tube placement and percutaneous drainage. After surgery, his general condition improved; the serum level of amylase normalized and the pleural effusion resolved. Pancreatic injuries are rare in pediatric blunt trauma; however, diagnostic difficulty is common with isolated blunt trauma. Therefore, a high index of suspicion should follow such an injury. We report the case of an 8-year-old boy with pancreas transection, ductal disruption, ascites, and pleural effusion who was successfully treated.

PURPOSE: To evaluate the clinical and radiographic findings of localized foreign body (FB) granulomas onmammograms. MATERIALS AND METHODS: This study involved 13 patients with localized FB granulomas on mammograms;their history of mammoplasty or other plastic procedures was obtained by telephone interviews. Two radiologistsanalyzed the location and morphology of FB granulomas and the presence of associated linear densities orparenchymal distortion on mammograms. Four patients underwent ultrasonography. RESULTS: No patient had a historyof mammoplasty. All 13, however, had a history of plastic procedure, three to 22 (average, 12) years previously,as follows : foreign materials including silicone liquid and oil such as paraffin been injected into the anteriorneck area of nine patients, the infra-auricular area of two, and the nose of two. Multiple small, high-density,flocculent nodules representing FB granulomas were distributed bilaterally in nine patients; they were noted inthe upper inner portion of 11 of 26 breasts. In eight patients, mammograms showed linear opacities suggestingfibrosis. There was no calcification or parenchymal distortion. Though in three cases, the masses were palpable.Ultrasonography revealed several anechoic nodules with posterior enhancement in subcutaneous fatty layers, and inone, 0.2cc of oil droplet had been aspirated under ultrasonographic guidance. CONCLUSION: Localized FB granulomasof the breast could be caused by the migration of FB from cervicofacial areas. Mammography showed characteristicdistribution of upper inner portions, and the findings were similar to those of mild interstitial mammoplasty.
