BACKGROUND: Hair casts(HGs) is a disorder of asymptomatic, firm yellowish white, freely movable accretions which encircles but is not attatched to the hairs. There are two types of HC:The first type, parakeratotic HC, is frequently associated with parakeratotic scalp disorders;the second type, the peripilar keratin casts, in an uncommon type not usually associated with diseases of the scalp and has only been reported in female children. The pathophysiology and origin of HC is poorly understood with only 37 cases reported in the literature. @ ES OBJECTIVE: our pupose was to establish the prevalence of hair cast in schoold children and to determine the predisposing factors of hair casts in Korea. METHODS: Five hundred and thirty-seven students of elementary schools(274male, 263female) were examined. Samples of plucked hair were stained with 4-dimethylaminocinnamaldehyde and examined under light microscopes. RESULTS: There were 182 patients with HC;Peripilar keratin casts:174(CRSC 165, ERSC 7, IRSC 2); paakeratotic HC:8. In a total of 182 patients with HC, 181 were girls and the incidence of HC in female children was 68.8%(181/263). In girls who tie up or weave their hair, the incidence of peripilar keratin casts was as high as 81.8%(171/209). CONCLUSIONS: These data suggest that the traction to the hair follicle may play a role in the generation of HC, and that peripilar keratin casts are not rare in Korea.

BACKGROUND: Becker's mealanosis is not an uncommon entity, and many cases are probably not reported because the diagnosis is usually made clinically and the condition is benign with cosmetic significance only. the etiology remains obscure. OBJECTIVE: The purpose of this study is to establish the clinicopathologic characteristics of Becker's melanosis in Korean. METHODS: Thirty-six patients with Becker's melanosis were retrospectively studied. RESULTS: The clinical and histopathologic findings observed in our cases were similar to previous reports except for the following. Nine patients(25%) had abnormal findings in their hair follicles : dilatation of the infundibular portion filled with abnormal keratin, Pityrosporum orbiculare and bacteria(19.4%); formation of intrafollicular cyst(5.6%). Three patients(8.3%) had granulomatous infiltration. Twenty-two patients(61.1%) had increased smooth muscle bundles. CONCLUSION: The findings associated with dermal hair follicles may be related to the pathogenesis of Becker's melanosis.

Malignant tumors arising from tendon and aponeurosis are very rare. Among those reported most have been interpreted as synovial sarcoma or fibrosarcoma until Enzinger in 1965 described a new type which he called “Clear Cell Sarcoma of Tendon and Aponeurosis”. The tumor has a uniform and distinctive clinical and morphological pattern which distinguishes it from other groups of tenosynovial tumors. The problem of its histogenesis remains, especially its relation to synovial sarcoma. In this paper, we reported one case which is believed to be “Clear Sarcoma in the thigh”.

Thirty one cases of acromioclavicular injuries were treated in both Kangnam Sacred Heart Hospital and Hangang Sacred Heart Hospital during the period from May 1974 to April 1981. Three cases were classified to type 2 injuries and twenty eight were type 3. Among 31 cases one of the type 2 injuries was treated with closed reduction followed by thoracobrachial cast and remaining thirty received surgical treatment. Twenty one cases were operated on by technique of Weaver and Dunn, 8 cases by modified Phemister method and one case by Stewart technique. Preperative and postoperative stress film were evaluated and cap the coracoclavicular distance were measured. In twelve complete dislocation the authors modified the original Weaver and Dunn procedure by taking a bone chip along with the acromial end of the coracoacromial ligament. This seemed to provide a strong bony fulcrum for the suture of the ligament to clavicle as well as promoting bone to bone union. The results of this modified procedure were excellent.

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

Dyschromatosis universalis hereditaria was reported in 1933 by Ichikawa and Hiraga in Japan. This disease is characterized by small pigmented and depigmented mottled macules on the trunk and extremities. We report two cases of dyschromatosis universalis. Case one is a 47-year-old man presented with hypoand hyperpigmented spots on the trunk and extrexities. At about 30 years of age, he started to show pigmentary changes on the back, which became progressively spread to the other parts of the trunk and extremities. Case two is a 27-year-old man with numerous mottled hypo-and hyperpigmented spots on the trunk and extremities. He started to show pigmentary changes on the back about 12 years ago. This pigmentary changes also became progressively spread to the other part of the trunk and extrimities. There were no family history of similar disease. On physical exminations, both patients had hrown rice-grain sized pigmented and depigmented macules without scales and atropy on the trunk and extremites. Fontana-Masson stains revealed decreased and increased melar in granules in the basal cell layers in the hypopigrnented and hyperpigmented lesions respectively.

Multiple endocrine neoplasi~a type 3 is a rare, heritable or sporadic, multiple neoplastic disorder that is charracterized by thyroid medullary careinoma, pheochromocytoma, multiple mucosal neuroma, and marfanoid habitus. The most important disorder of the syndrome is mucosal neuroma that is an early diagnostic sign of multiple endocrine neoplasia type 3. Early diagnosis of MEN type 3 determines prognosis of the disease. We present a case of multiple endocrine neoplasia type 3 of the sporadic pattern in a 27-year-old man who had typical medullary thyroid carcinoma, mucosal neuroma, marfanoid habitus, and megacolon.
