The transarterial embolization has been widely used to control bleeding. It has a variety of clinical utility; to reduce bleeding on the surgical field, to reduce the size of malignant tumor as a preopearative treatment, to treat arteriovenous malformation or arterial aneurysm as a curative method and to promote life qua' ity of patient with diffuse or multiple hepatocellular carcinoma as a palliative treatment, etc. With the advance of modem technology, various embolic materials have been also developed. IIowever, it has not- been -fully investigated of histopathologic changes of the embolized organs according to the embolic materials used. This study was undertaken to investigate the histopathologic changes of embolized renal artery in rabbit by various embolic materials, according to each embolic material and to time passed by after embolization. Of the 5 arteries embolized by ethylene vinyl alcohol copolymer(EVAL), one showed abscess formation in embolized kidney. The other 4 allowed to perform further pathologic study: within a week after embolization there was no any specific change in vessels, however, r,unimal endothelial hypertrophy was observed following 2 weeks of embolization. Of the 8 renal arteries embolized by N-buthyl-2-cyanoacrylate(Histoacryl), 4 showed total occlusion of the main renal arteries as well as renal infarction, which reflects the strong adhesiveness of Histoacryl to vascular wall. The other 4 showed fibrinoid degeneration in vascular wall within a week. However, further change was not observed thereafter. In all the 5 renal arteries embolized by polyvinyl

Adenoid cystic carcinoma is known to be a neoplasm of the major and minor salivary glands but it also occurs in the lacrimal gland, external auditory canal, easphagus, breast and skin. Adenoid cystic carcinoma of salivary gland is a slow-growin nalignant tumor. Although metastasis of this tumor clevelnps in about half the cases, its meta taes to the overlying skin is not common, moreover the skin metastasis to the remote site is raely found. Primary cutaneous adenoid cystic carcinoma is rare and histologically indistingisl able from skin metastasis of adenoid cystic carcinoma of the salivary gland. A 53 year-old man presented a solitary, well defined, erythen at us, 1.3 x 1.3cm sized nodule on the vertex of the scalp, which revealed the typical histopatholog ndings of adenoid cystic carcinoma. One and half years ago, a tumor of the parotid gland va removed and proved to be a cribriform pattern of adenoid cystic carcinoma. The skin lesion was diaghosed as a skin metastasis of the alenoid cystic carcinoma of parotid gland rather than a primary cutaneous adenoid cystic carcinona because a similar pattern of adenoid cystic carcinorom had been discovered on the parotidg an l although it developed on the scalp, the usual site of primary cutaneous adenoid cystic carcinama.

Korean Journal of Dermatology 1995;33(2):322-326
Intravascular papillary endotholial hyperplasia is a relatively rare (istose which is characterized by the development of endothelialdined papillary projections in a vascula humen. It is commonly found to be associated with thromboticrraterial and is now considered a reative process of the endothelium rather than a neoplastic one. Although this disease usually presents petri dish or bluish nodule on the head, neck or upper extremiti it can develop anywhere on the bod, . There are many reports about lesions in unusal locations, but t.hey are almost always solitary. A 61-year-old woman complained of multiple, tender, 1 x 1 to 4 x 5 creasized nodules on both hands, antecubital fossa, chest, abdomen, left shoulder and right calf. These the nodules showed reddish to bluish colors and had long hisbiries from 1 year to 7 years. Four our 13 lesions were excised for histopathologic diagnosis intravascular papillary endothelial hyperplaian 3 lesions and cavernous hemangioma in 1 lesion.(

Hypergammaglobulinemic purpura of Waldenstrom is a distinct syndrome consisting of recurrent episodes of purpura, elevated serum r-globulins, elevated erythrocyteed rnentation rate, and mild anemia. This disease has been divided into the prirnary type without an uncerlying disease, and the secondary type with a known underlying disease. We diagnosed a hypergammaglobulinemic purpura of Waldenstram in a 53-year-old woman who presented sudden onset of showers of purpuric macules and petechiae of 24 hours duration involving her lower extremities with a 10-rnonth history. She showed characteristic laboratory findings consistent with those of hypergammiglobulnemic purpura of Waldenstrorri and also showed positive results of antinuclear antibody and rheumatoid factor. We tried to find out if there we any associated underlying disases such as systemic lupus erythematosus or Sjogren synirorne through various tests but faile it find any. We concluded she showed a primary type of hypergarnmhglobulinemic purpura of Waldcnstrorn.

The authors reviewed 50 patients of congenital dislocation of the hip who had surgical treatment at the Department of Orthopedic Surgery, Seoul National University Children's Hospital from October, 1985 to August, 1993. We investigated the contributing factors to coxa magna after surgical treatment and it's relationship to the avascular necrosis of femoral head, and observed the influnce of coxa magna on the development of the hip joint. Coxa magna was defined as a femoral head with the greatest diameter 15% greater than the opposite side. To assess the development of the acetabulum in the hips with coxa magna, radiographical horizontal and vertical parameters were measured preoperatively, and at postoperative 1 year, 2 year, and 3 year or more. Twenty-one of fifty hips had coxa manga. The incidence of coxa magna increased in patients who had open reduction at younger age(average 30 months), compared to older age(average 44 months). Neither femoral osteotomy nor pelvic osteotomy increased statistically the incidence of coxa magna. Avascular necrosis of femoral head did not necessarily resulted in coxa magna. There were not statistically significant differences in the coverage ratios of femoral head by the acetabulum between coxa magna positive and negative groups, because lateral acetabular growth accompanied in accordance with enlargement of femoral head in the majority of cases with coxa magna. Open reduction alone caused concomitant vertical overgrowth of ipsilateral hemi-pelvis with resultant pelvic tilt and leg length inequality(IHD>5mm, upto 2cm) in 6 of 10 cases. The patients, who had coxa magna with good radiological results by Severin's classification, underwent open reduction at younger age and had lesser enlargement of the femoral head, compared to those with fair or poor results.

Owing to the advancement of imaging techniques which include the CT scan, it became easier to evaluate fracture patterns of calcaneal fractures accurately. Moreover, it is possible to obtain good results with operative treatment as a consequence of the development of good operative equipment and new operative technique. In 1988, Regazzoni and Benirschke in 1990, recommended L-shaped extensive lateral approach for calcaneus which provide extensive exposure of calcaneus and so allow easier reduction and fixation. We carried out L-shaped extensive lateral approach in 11 cases from June, 1993 to April, 1994. This approach did not produce any skin problems and allowed excellent anatomical reduction and fixation. But we experienced some severe causalgia on the heel region in several cases. We tried to analyse the cause of pain and concluded that it was the damage to the lateral calcaneal branch of the sural nerve. We are reporting the problems of tbis approach.

Familial polyposis is inherited as an autosomal dominant trait. It is characterized by the progressive development of hundreds to thousands of adenomsteus polyps in the large intestine. A patient who inherited the gene for familial polyposis is asually asymptomatic until after puberty, at which time polyps begin to appear. The disease at first non-malignant but after an interval of a few months or years, the development of colon cancer is inevitable. In Korea, several cases were reported, but almost all of the cases had incomplete familial histories. We experienced one case of familial polypasis in 33-year old Korean male who had no malignant changes in the adenomatous polyps. Among his family, his father and his brother have adenomatous polps in the colon and the rectum confirmed through total colonoscopy with biopsy. We report a case of familial polyposis of colon with a brief review of literatures.
