The methods of treatment of discoid meniscus have been in controversy and there are so many reports which represent different results. We analyzed the results of the 91 knees with discoid menisci of 84 patients who had been treated with arthroscopic partial or total meniscectomy, open partial or total meniscectomy, semi-arthroscopic total menisceetomy form June 1982 to Dec. 1987. The puropse of this paper is to present the indication and prognosis of the each method of treatment. There were 45 cases of male, 46 cases of female, and 10 patients were affected both knee. 2 patients who had served arthroscopic partial meniscectomy were reoperated by arthroscopic total meniscectomy due to recurrence of symptom. We classified the types of tear into 7 classes and observed the clinical characteristics and results. The methods we applied were arthroscopic total meniscectomy 40 cases, semi-arthroscopic total meniscectomy 25 cases, arthroscipic partial meniscectomy 16 cases, open partial meniscectomy 3 cases, open total meniscectomy 2 cases, and conservative treatment after arthroscopic diagnosis 5 cases. The follow up cases were 56, and period of follow up was ranged form 11 months to 5 years and 4 months (av. 2 years and 8 months). The results were followings : l. 71.4% of the patients were placed between 11 years and 30 years old, and there was no sexual difference. 2. 11.9% of the patients were affected bilaterally. 3. The commonest clinical symptom and physical sign was clik (67%) and quadriceps muscle atrophy (48.4%) 4. Diagnostic accuracy of knee arthrogram was 88%, but it could not demonstrate the type of tear. In arthrographic finding, the older the patient, the thinner the meniscus was. 5. The commonest type of tear was type V(34.1%) and it was followed by type II (19.8%). 6. There was no difference between the long term results of arthroscopic and semi-arthroscopic total meniscectomy. 7. The results of total meniscectomy is better than partial meniscectomy.8. The method of treatment should be chosen according to the type of terar, so partial meniscectorny is recommended for type II, IV and total meniscictomy is recommended for type III, IV, V and VI. 9. Less hospitalization, earlier recovery, and better result were obtained by the arthroscopic or semi-arthroscopic total meniscectomy.

There are many options for the management of osteoarthritis of the knee joint. Recently, arthroscopic surgery has been added to the armamentorium of the treatment modalities in osteoarthritis of the knee which does not respond to conservative treatment. Among 74 arthroscopic pocedures(including partial menisectomy, removal of loose bodies, synovectomy, cartilage drilling and simple lavage) done for osteoarthritis of the knee, 68 patients studied at average 3.1 years after procedure and the results were as follows 1. Seventy-one percent of patients had at least 2.5 years or more relief of pain and symptoms. 2. Fifty-six percent were still good at follow-up of 3.1 years. 3. The best result were obtained after removal of loose bodies and resection of unstable flap tear of a meniscus in association with mild osteoarthritis. 4. The poor result were obtained in patients with severe degenerative changes of both femoral condyle, 5. The results were much better in the normally aligned knee compared with valgus knee.

Trichoblastic fibroma is a benign trichogenic tumor that has both epithelial and mesenchymal components and exhibits partial follicular induction. We studied 4 cases of trichoblastic fibroma and reviewed their clinical and histologic features. Two tumors were present in the face. The remaining two were in the vulva and perianal area, respectively. The age of the patients ranged from 53 to 68 years, with an average age of 62. All were female. Histologically, the lesions showed a well circumscribed mass, located at dermo-subcutaneous junction in three patients and subcutaneous in one. They demonstrated mesenchymal induction evidenced by hair germ-like structure and perifollicular sheath. There was no connection between the tumor and epidermis. Differentiation toward hair structure led to the formation of the infundibulum through inner root sheath. Trichoblastic fibroma may be confused clinically and/or histologically with basal cell carcinoma. Identification of the mixed epithelial and mesenchymal components, and the absence of epidermal connection and cleft within the stroma are important in differentiating this benign neoplasm from basal cell carcinoma.

Primary malignant parovarian epithelial tumors are extremely rare, with only 56 cases previously reported in the world literature. Most parovarian epithelial tumors are of paramesonephric (Mullerian) origin. In this article, we report the first case in the Korean literature of papillary serous cystadenoma of borderline malignancy from paramesonephric parovarian cyst. This case presented here is of particular interest since this neoplasm is rare. A 48-year-old female underwent a hysterectomy with bilateral adnexectomy and pelvic lymph node dissection for a cystic tumor of the right parovarian area. The tumor, measuring 13 cm in diameter, was apart from the ovaries, fallopian tubes and uterus. The cyst wall had well-developed smooth muscle layers. The cyst was lined with mildly atypical ciliated and non-ciliated low columnar cells compatible with those of paramesonephric origin. From the inner surface of the cyst several cauliflower-like structures projected into the lumen. They were of a predominantly papillary architecture covered by atypical epithelial cells with piling-up and occasional glandular growth. No destructive stromal invasion was identified.

Pseudoxanthoma. elasticum is a rare, heritable, systemic disease of connective tissue characterized by degeneration of elastic tissue and mainly affecting the skin, eyes and blood vessels. Recently, according to Pope (1974), it can be inherited as an autosomal dominant or recessive trait. We presented a study of 5 cases of pseudoxanthoma elasticum of autosomal recessive inheritance, which showed typical peau d'orange skin lesions. Two among the 5 cases were associated with angioid streaks, a case with myopia and broderline mental retardation, and 2 cases without any other systemic disturbances.

BACKGROUND: Epidermal grafting using cryotherapy for recipient sites is in widespread use. However the peripheral hypopigmented haloes that occur around the recipient sites require prolon gation of the treatment period. OBJECTIVE: We used a CO2 laser to remove the epidermis of the recipient sites for betteri results. METHODS: We treated lie localized vitiligo patients with CO2 laser to remove t.he epidermis and grafted suction blister rooves. We observed repigmentation and complications 1 month later. RESULTS & CONCLUSIONS : The superiority of this method is demonstrated by the fact 1) all prodedures can be completed on the day of operation 2) the incidence of hypertrophic scar and peripheral hypopigmented halos can be observed.The problems of this method are 1) uneven repigmentation of recipient. sites 2) hyperpigrnentation of recipient sites

Until recently, the gastrointestinal lymphomas were classified according to the criteria developed for the node-based lymphomas. In recent years, the REAL classification provided a new category of MALT lymphoma and Mantle cell lymphoma in B-cell lymphomas. Low-grade MALT lymphomas have been well characterized clinically, histologically, and immunophenotypically. We retrospectively recategorized 41 cases of the primary gastrointestinal B-cell lymphoma and investigated the expression of cyclin D1, bcl-2, bcl-6, p53 protein, and PCNA by immunohistochemical method. The cases were categorized in 5 groups, low grade MALToma, low/high grade MALToma, high grade MALToma, diffuse large cell lymphoma, and mantle cell lymphoma according to the morphological findings. The expression of cyclin D1 protein was restricted to the cases of mantle cell lymphoma. The bcl-2 protein expression was higher in the low grade MALT lymphoma than in the high grade lymphoma (P=0.006). The bcl-2 protein expression was higher in the low grade area than in the high grade area in the low/high grade MALT lymphoma (P=0.005). The bcl-6 and p53 protein expression was higher in the high grade MALT lymphoma than in the low grade lymphoma (P=0.022, P<0.018). However, the bcl-6 protein expression of the tumor cells was higher in high grade area than in low grade area in the low/high grade MALT lymphoma (P=0.004). The degree of the PCNA expression was positively correlated with the grade of the malignant lymphoma (P=0.003). The above results suggest that the cellular proliferation assessed by PCNA index correlates with the histologic grade. And the bcl-2, bcl-6, p53 protein may be effective in the transition from the low grade MALT lymphoma to the high grade lymphoma. Therefore, we can differentiate the low grade lymphoma from the high grade lymphoma by the immunohistochemical staining for cyclin D1, bcl-2, bcl-6, p53 protein and can predict the prognosis of the patients in accordance with the grade of the tumor.

Acute pyogenic arthritis in renal transplant patient is one of the serious problem resulting in significant morbidity and mortality. The purpose of this paper is to analyze seven patients in whom acute pyogenic arthritis developed following renal transplantation. Pyogenic arthritis developed in seven (0.7%) out of 958 renal transplant patients whose transplanted kidney functioned well for more than two years. The age of the patients ranged from 37 to 65 years with a mean of 48 years. All patients were male. Pyogenic arthritis developed between the period of one and 12 years (mean: 4.5+/-4.2 years) following transplantation. Causative organisms were Staphylococcus aureus (three), E. coli (two), Salmonella (one) and Acinetobacter bananii (one). Involved joints were four knees, one hip, one elbow and one finger. Two patients improved on a conservative regimen of bed rest and antibiotics and five patients required open drainage. However, pyogenic arthritis recurred in three years, four years and seven years after renal transplant in one patient. Looking at the probable risk factors of age, sex, immunosuppresants, diabetics and acute graft rejection, diabetics and older age (over 40 years old) are highly associated with post renal transplant pyogenic arthritis.

Subperiosteal Cortical Defect is a symptomless rarefaction of cortical bone which begins most often on the external surface of the medial and posterior cortical walls of the lower end of the femur in children between the ages of 3 and 6 years. The name of Subperiosteal Cortical Defect was first used by Aegerter who differentiated it from non-osteogenic fibroma. The authors found out 5 positive cases of incidental findings among 62 cases of both knee joint X-ray of which 3 was male and 2 was female. Also we experienced 3 cases which necessiat d a correct diagnosis and differential diagnosis. Because this is a common lesion, it frequently accompanies more serious bone conditions, and because this is self-limited disease, treatment is not necessary. It was emphasized that its nature should be understood by all those dealing with bone disease lest it be overdiagnosed and overtreated.
