Disseminated superficial porokeratosis (DSP) is a specific disorder of keratinization. Genetic studies show that DSP is an autosomal dominant trait. Clinically, the lesions show a sharply demarcated and hyperkeratotic plaque with central atrophy. The lesions appear mainly in the extremities and generally develop with bilateral symmetry. Unusual cases of DSP accompanied by severe pruritus have been reported as "eruptive pruritic papular porokeratosis" or "inflammatory DSP." Histopathologically, inflammatory DSP is characterized by the presence of cornoid lamella with a dense infiltration of eosinophils and lymphocytes in the perivascular area of the upper dermis. Here we report a case of inflammatory DSP in a 84-year-old man with colon cancer who presented with multiple hyperpigmented atrophic macules.

Sebaceous hyperplasia usually presents as solitary or multiple, small, yellowish papules on the face, particularly on the forehead. It occurs most commonly in middle-aged individuals and rarely in early adult life. It has also been reported in the vulva, penis, and areola. Histological examination reveals a single greatly enlarged sebaceous gland composed of numerous lobules grouped around a centrally located, wide sebaceous duct. We report a case of a 26-year-old man with sebaceous hyperplasia in the ventral surface of the distal penile shaft, an unusual site.

Authors report a ganglion cyst located in spinal canal. The ganglion cyst is soft and movable mass in connective tissue around peripheral joints or tendon sheath. It has been rarely reported in lumbar spine. Symptoms and signs are usually difficult to distinguish it from other etiologies of radicular pain. The extradurally located ganglion cyst at L4-5 level which caused back pain and sciatica was removed with partial hemilaminectomy. Radiological finding of cyst in MRI may be variable, according to the composition of the cyst. Based on our experience and pertinent literatue, a ganglion cyst should be considered in the differential diagnosis of radicular pain in the presence of degenerative changes of the lumbar spine.

A new technique of endoscope assisted anterior cervical foraminotomy was developed to improve the conventional microsurgical anterior cervical foraminotomy. Microsurgical anterior cervical foraminotomy provides direct anatomical decompression of the compressed nerve root by removing the spondylotic spur or disc fragment while preserving the functioning segment of the disc. The authors modified the anterior cervical foraminotomy using the MED TM(Microendoscopic discectomy) system to minimize the skin incision, and to achieve safe drilling and easy retraction. The uncinate process was drilled under endoscopic visualization through a tubular retractor. This technique has been applied to 13 patients with single level radiculopathy due to posterolateral osteophyte or soft disc herniation. The nerve roots were decompressed successfully under endoscopic control as in conventional microsurgical foraminotomy through a 2cm skin incision. Postoperatively, all patients showed improvements in their radiculopathic symptomatologies. Corresponding CT scans confirmed satisfactory anatomical decompression in all patients. This surgical technique has shown good clinical outcomes with fast recovery.

We report three cases of patient with pleomorphic xanthoastrocytoma(PXA). PXA is a clinicopathologically distinct variant of cerebral astrocytoma which is a low-grade leptomeningeal glioma affecting under the age of 30 years. This tumor has a favorable prognosis, but histological and neuroradiological findings suggest malignant brain tumor. Occasionally these may be confused with malignant gliomas. Clinical features from our three patients were manifestation of increased intracranial pressure and all cases were under the age of 30 years and females. Two patients had superficial location in the right frontal and left temporal respectively, but remaining one(case 2) which was associated with arteriovenous malformation in the left frontal region was in the right lateral ventricle. The intraoperative histological evidence by frozen biopsy suggested glioblastoma or anaplastic astrocytoma in all cases which confirmed to be PXA by postoperative histological examination. Two cases which had been resected subtotally were followed by cranial irradiation without therapeutic efficacy. Optimal management of PXA is primary surgical resection to reduce recurrence of tumor and to secure long-term survival. Therefore, differentiation of PXA from malignant brain tumors and intraoperative diagnosis of PXA is imperative to treat PXA effectively.

Unilateral hypoplasia of the pulmonary artery is an uncommon anomaly, which commonly develops in combination with congenital cardiovascular defects such as tetralogy of Fallot, patent ductus arteriosus and septal defect of atrium or ventricle, but may also present as an isolated lesion. We have recently experienced a case of the left pulmonary artery hypoplasia in adult by chance of during the general health screen, which diagnosed by chest X-ray, chest spiral CT, lung perfusion and ventilation scan, digital substraction angiogram and bronchoscopy, then presented hereby with the review of relevant literature.

Lichen planopilaris is a follicular variant of lichen planus. When it appears on the scalp and is accompanied with hair loss, it is classified into a subtype of cicatrical alopecia. And lichen planopilaris can be classified into classic lichen planopilaris, frontal fibrosing alopecia, Graham-Little syndrome. A 63-year-old man presented with a 3-year history of hair loss on the area of occipital skin and 3-week history of pruritic, confluent, purple-colored, flat-topped papules on the same area with decreased follicular ostium. Histopathological findings showed both characteristics of the cicatricial alopecia and those of lichen planus; Loss of the hair follicles, atrophy of the sebaceous gland and sweat gland, and bandlike inflammatory infiltration on the upper dermis, especially on the perifollicular and interfollicular area.

case of occult intrasacral meningocele associated with arachnoid cyst in a 35-year-male is reported. The patient presented with a history of severe sacrococcygeal pain, constipation, and urinary incontinence for several months. Myelography revealed delayed filling of a meningocele. Computed tomographic(CT) myelography and magnetic resonance(MR) imaging showed huge intrasacral mass without neural elements. A favorable outcome was achieved by decompression of the cyst, obliteration of the conduit to subarachnoid space, and fenestration of arachnoid cyst into subarachnoid space.

PURPOSE: The purpose of this study was to evaluate the usefulness and difference of fixation persistence with two different fixation materials (Mersilene tape and Dall-Miles cable) in modified Weaver-Dunn operation. MATERIALS AND METHODS: Twenty-five cases of acute acromioclavicular dislocation were surgically treated with modified Weaver-Dunn operation, and followed for an average about 15.8 months. For the fixation material, Dall-Miles cable were used in 10 cases, Mersilene tape in 15 cases. Radiological and clinical evaluation were done in all cases. For clinical evaluation, UCLA shoulder function test and ASES score were used. RESULTS: Excellent results were noted in group with Mersilene tape 6 cases and Dall-Miles cable 4 cases, good in 8 cases and 6 cases, and fair in 1 case only Mersilene tape in UCLA shoulder function test. The difference of coracoclavicular distance between injury side and normal side were analysed in radiologically at before, after and 3 months after operation. Results are as follows; 11.2 mm, -0.5 mm, 0.5 mm, 0.8 mm in group with Mersilene tape, 10.3 mm, -0.5 mm, 1.4 mm, 1.7 mm in Dall-Miles cable. CONCLUSION: Two different fixation material used in the fixation of modified Weaver-Dunn operation have enough fixation power for clinical outcome. But Mersilene tape was better than Dall-Miles cable in the persistency of fixation and handling.
