A primary genitourinary melanoma is rare, accounting for less than 1% of all cases of melanoma. They have been presented in case reports, with a subsequent paucity of insight into the natural history of the disease and appropriate management of patients. The prognosis of patients with a genitourinary melanoma is poor. Delay in seeking medical attention for symptoms, and misdiagnosis at presentation, contribute to a more advanced stage at diagnosis. Our case involved a 71 year old woman, who came to our hospital due to vaginal spotting. On local excision, mass was found on the vestibule and forward to the urethra. The pathological diagnosis, by special immunohistochemical staining, such as S-100 protein and HMB-45, was that of a malignant melanoma.

Radiation recall phenomenon is an inflammatory reaction which occurs at a previously irradiated area after the administration of causative agents, especially anticancer drugs. Radiation recall mostly involves skin and rarely affects internal organs. We, hereby, report a rare case of radiation recall myositis. A 51-years-old man visited the hospital due to pain and weakness of the left thigh. He had been diagnosed with a skin metastasis of pancreatic adenocarcinoma, at the left thigh and treated with radiotherapy and subsequent combination chemotherapy of 5-FU and cisplatin. After the 5th cycle of chemotherapy, the patient developed pain and weakness localized at the previous radiation field. An MRI revealed myositis of left gluteus medius muscle. Muscle biopsy showed no malignant cells or signs of infection. He was diagnosed as having radiation recall myositis and treated with steroid and NSAID. Soon after, pain and weakness gradually improved. Although rare, a possibility of radiation recall myositis should be considered when a patient with history of radiotherapy has a myopathy.

Behcet's disease (BD) is a rare, multisystemic disorder characterized by vasculitis. Although renal involvement rarely coexists with BD, several types of renal involvements have been reported: amyloidosis, glomerulonephritis and vascular involvement. Herein, we report a rare case of BD complicated with IgA nephropathy (IgAN). A 42-year-old woman visited the hospital due to joint pains and painful subcutaneous nodules. Based on her medical history of recurrent orogenital ulcers, arthritis, enteral ulcers, erythema nodosum-like skin lesions, and a positive pathergy test, we diagnosed her with BD. To evaluate proteinuria, we performed a renal biopsy. The patient was diagnosed with BD complicated with IgAN, and treated with a low dosage of steroid, colchicine, as well as angiotensin II type I receptor blockers. Although renal involvement in BD is rare, it is important to periodically perform renal function assessments in patients with BD involving abnormal urine results.

A 59-year-old woman presented with abdominal pain. Abdominal computerized tomography was suggestive of biliary stones. During endoscopic retrograde cholangiopancreatography, adult worms resembling Clonorchis sinensis (C. sinensis) were drained. Eggs were detected in stool using the formalin-ether concentration method and C. sinensis-specific antibody was detected in the serum. A diagnosis of C. sinensis infection was made. The symptoms of the patient gradually resolved after treatment with anti-parasite medication. The patient lived in a non-endemic region for C. sinensis infection and had no history of intake of raw or undercooked freshwater fishes. South Korea is one of the endemic countries for C. sinensis infection and people can be infected via indirect routes of transmission such as cooking utensils. Therefore, the possibility of C. sinensis infection should be considered in patients presenting with biliary diseases in South Korea. We describe the clinical findings of this case with a review of literature.

BACKGROUND AND PURPOSE: Alzheimer's disease (AD) is associated with structural alterations in the medial temporal lobe (MTL) and functional alterations in the posterior cortical region, especially in the early stages. However, it is unclear what mechanisms underlie these regional discrepancies or whether the posterior cortical hypometabolism reflects disconnection from the MTL lesion or is the result of local pathology. The precuneus, an area of the posteromedial cortex that is involved in the early stages of AD, has recently received a great deal of attention in functional neuroimaging studies. To assess the relationship between the precuneus and hippocampus in AD, we investigated the volumes of these two areas using a magnetic resonance volumetric method. METHODS: Twenty-three subjects with AD and 14 healthy age-matched controls underwent T1-weighted three-dimensional volumetric brain magnetic resonance imaging. Volumetric measurements were performed in the precuneus and hippocampus. RESULTS: Compared to controls, AD patients exhibited a significant reduction in total precuneal volume, which was more prominent on the right side, and significant bilateral reductions in hippocampal volume. No correlation was found between the total volumes of the precuneus and hippocampus in the AD group. CONCLUSIONS: These results suggest that volumetric measurements of both the precuneus and hippocampus are useful radiological indices for the diagnosis of AD. Furthermore, the lack of correlation is attributable to local pathology rather than being a secondary consequence of MTL pathology.

The primary success rate of intraluminal angioplasty for long superficial femoral artery (SFA) occlusions is low due to the long occlusion length and the hard component of the occlusion. To overcome this problem, subintimal angioplasty has been previously proposed and this technique is now considered as an effective method for the treatment of SFA occlusions. Subsequently, various devices and strategies have been developed to increase the success rate of subintimal angioplasty for SFA occlusions. Here, we present a case in which a long chronic total occlusion of SFA was successfully recanalized by the retrograde subintimal angioplasty through the popliteal artery after the failed antegrade subintimal approach.

The retrograde approach through a collateral artery is now thought to improve the success rate of percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO), and different kinds of strategies for this technique have been developed. However, the basic principles of PCI for CTO, such as firm back-up support with a guiding catheter and fine control of the guide wire, should be adhered to more strictly to succeed with this complex procedure. We present a case in which a CTO of the proximal left anterior descending artery was successfully opened by the retrograde approach through a collateral from the left circumflex artery, during which two guiding catheters were simultaneously used in the same coronary artery for the purpose of strong back up support for the retrograde device and fine control for the antegrade device.

Behcet's disease is a chronic systemic inflammatory disorder with an unknown etiology. It affects many organs and is characterized by recurrent attacks. Pulmonary artery aneurysms occur more frequent in males, and it is o ne of the rare pulmonary complications of Behcet's disease. It has a poor and prognosis, and is also one of the leading causes of death from Behcet's disease. Here we report a case of suspected Behcet's disease diagnosed by a manifestation of a pulmonary artery aneurysm in a 37-year-old woman.
