The cutaneous lymphadenoma is a recently described tumor with a distinctive histologic picture representing a basaloid epithelial proliferation and intraepithelial lymphocytic infiltration; it seems to be a benign adnexal neoplasm of uncertain histogenesis. We documented one example of cutaneous lymphadenoma showing typical histologic features. The tumor typically presented as a well circumscribed nodule with scant or no epidermal connections. The proliferating one consisted of multiple rounded lobules of basaloid cells with some degree of peripheral palisading. There was an intense infiltrate of small lymphocytes within the lobules but few in the stroma. No clear adnexal differentiation is noted. Immunohistochemically, the basaloid cells show weak immunoreactivity for high molecular weight keratin and carcinoembryonic antigen, small lymphocytes for T-cell marker and some dendritic cells for S-100 protein. After surgical resection, we found no evidence of local recurrence or distant metastasis for four years, so we considered this tumor as a benign one and diagnosed as cutaneous lymphadenoma by typical histologic features.

Several observation suggest that the antimelanocyte autoantibodies could play a role in melanocyte destruction. Some experiments indicate that melanocyte antibodies from patients with vitiligo can kill melanocyte in vitro. In these experiments, we demonstrated that vitiligo patient's sera containing antimelanocyte antibodies can lyse cultured human melanocytes by complement activation. Melanocyte cytotoxicity was measured using the ethidium bromide/ acridine orange viability assay. Significant melanocyte cytotoxicity was seen in sera from patients with both active and inactive vitiligo(p<0.01). Melanocyte cytotoxicity measured with complement-mediated cytotoxicity decreased after systemic steroid treatment(p<0.05) ; however melanocyte cytotoxicity showed no significant change with systemic PUVA therapy.

[Objective] To determine the long term survivorship and establish the idea I correction angle in proximal tibial osteotomy for primary osteoarthritis. [Method] Seventy-nine patients suffering from primary osteoarthritis (111 knees) were performed with proximal tibial valgus osteotomy from 1985 to 1997, among which 74 women (106 knees) and 5 men (5 knees). The age ranged from 37 to 70 years (mean, 55 years). Postoperatively, hospital for Special Surgery knee score (HSS) was used for clinical assessment. The femorotibial angle (FTA) was measured to classifiy patients to group Ⅰ of 61 knees with less than 7 of valgus; group Ⅱ of 23 knees with 7~9 of valgus; group Ⅲ of 27 knees with over 10 of valgus. Closed wedge osteotomy was performed in all cases. HSS was assessed pre-and post-operatively. [Result] The average follow-up period was 9 years and 6 months (2 years and 4 months to 14 years and 1 month). The HSS knee score averaged 60 points preoperatively, 94 after 1 year and 87 at the last follow-up. Falure I was the need for conversion of a proximal tibial osteotomy to a total knee arthrop lasty, and Failure Ⅱ was the need for conversion of HSS knee score of less than 60 points. The 4 and 14 years survival rates were 99% and 85% using the first definition of failure, and 96. 4% and 75.1% using the second. [Conclusion] Proximal tibial osteotomy is reliable for treating unicompartmental osteoarthritis, providing that the postoperative femorotibial angle is corrected to more than 7° of valgus and falls in the range of 10°~15°.

PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.

BACKGROUND: PUVA has been used effectively in the treat,ment of vitiligo, but the mechanism by which PUVA stimulat.es melanocyte proliferation in vitiligo is not known. Several mechanisms have been suggested to be involved in the process of repigmentation of vitiligo. First, UV light, with or without psoralen, directly stimulates the proliferation of melanocytes. Secondly, PUVA may act. on epidermal keratinocytes or dermal components to stimulate t,hem to release certain melanocyte growth st,inulation factors that enhance the proliferation of melanocytes in depigmented lesions. Thirdly, PUVA irnmunologically leads to the impairment of epidermal Langerhans cell function and alteration of circulating T and B cell function, which results in the suppression of the stimuli is for rnelanocyte destruction during the therapy. OBJECTIVE: To test, th hypothesis that PUVA induced repigmentation in vitiligo results from the stimulation of growth factors that induce melanocyte proliferation, and that PUVA may suppress the immune reacticin to melanocytes, especially in autoantibody synt,hesis, we examined the effects of sera on the growth of epidermal melanocytes and control cells, and t,he incidence of antibodies to melanocyte and melanoma cells(SK-Mel 2~3) in the sera of patients with vitiligo. We also had normal control individuals and studied the changes of the antibody titer in the sera of patients with vitiligo. METHODS: The rate of H thymidine uptake was estimat,ed in cultured melanocytes and fibroblasts t,reated by patients sera before and after PUVA treatment. SDS-PAGE and immunoblotting analysis were used to idcntify anti pigment cell autoantibodies and were compared to the titers of autoantibodies after PUVA. RESULTS: 1. Melanocyte and fibrablast proliferation was increased by PUVA treated sera. Their proliferation was in proportion to the duration of the PUVA treatment. Melanocytes proliferated more than fibroblasts. 2. Significant differences between vitiligo patients and normal controls were found in the inci dence of anti-pigment cell antibodies. The antibodies were predominantly directed to melanocyte antigens of 110 kD, 65 kD, 45 kD and melanoma cell antigens of 110 kD, 103 kD, 88kD, 70 kD, 56 kD, 41 kD. 3. The titer of anti piment cell antibodies showed a tendency to decrease after PUVA treat- ment in most patients regardless of clinical improvement. Conclusion ; PUVA treated sera induced proliferation of melanocytes and fibroblasts and the production of aut,oantibodies was suppressed against pigment cell antigens through irnmunosuppression, which might help in the repigmentation of vitiligo.
