Squamous cell carcinoma of the lower lip can be developec by a number of underlying etiologic factors, the most outstanding of which is solar irracdiation, and is considerably more aggresive and has a much higher incidence of metastatic spread. Its early detection and effective treatment afford a high cure rate. Cryosurgery is a simple, efficient and effective method of treatment of skin cancer and is now a widely accepted modality for the treatment of these lesions. Two patients(67-year-old male and 57-year-old female) were presented with solitary or two masses on the lower lip without regional lymphadenopathy. These two cases showed clinical and histopathologic findings of squamous cell carcinoma. They were successfully treated by cryotherapy with liquid nitrogen without any significant side effects.

Leukemia cutis is defined as infiltration of the skin by malignant leukocytes that have originated from the bone marrow. The cutaneous eruption of leukcmia may be divided into the specific and non-specific lesion (leukemid). These may occur separately or in combination. True leukemia infiltrations of the skin consist of nodular, diffuse, or plaque-like infiltrations with swelling, macules, papules, ecchymoses, palpable purpura, erythroderma, and ulceration. A 55-year-old man presented with multiple as mptomatic dark-brown nodules on the whole body with recurrent gingival bleeding. The patient developed seoticemia and died 6 months after the onset of the disease.

Histoid leproma usually occur in pat.ients with lepromatous leproy who have had relapsed after being undcr treatment(usually sulfones) for a long time and who have shown variable improvement. A 56 year old female patient who had been suffering from lepromatous leprosy and had been treated which clapsone relatively regularly for approximately 28 years had a history of several shiny rice grain t.o peanut sized nodules on the face and right flank. Histopathologic examination of a specimen taken from a nodular lesian revealed a well circirmscrihed nodule composed mainly of spindle-shaped cells and epithe:ioi 1 cells on the upper and mid-levmis, and granuloma composed of epithelioid cells, multinucleated wait cells and foamy histiocytes on the lower dermis. In AFB stain, numerous acid-fast bacilli were scatt red dermis and epidermis, especially stratum corneum. This study opplied a polymease chain reaction(PCR) on sections of biopsy tissues and peripheral blood of pat.ient. Positive amplification of a 530 bp fragment was deteated not only in the lesion tissues but also in the per ipher al blood.

A 17-year-old woman had an extensive nevus comedonicus affecting the left sides of the breast, trunk, axilla, and upper extremity. Her condition was complicated by episodes of re-current cyst formation, secondary infection, and atrophic scars. We performed various therapeutic approaches include topical keratolytic agents, manual extraction of comedones, excision of smaller lesions, and systemic antibiotics but the response was unsatisfactory. We tried systemic isotretinoin and minocycline and the pustulation of the lesions was reduced. Herein we report a rare case of linearly arranged extensive nevus comedonicus.

A clinical observation was made on 45 of 53 patients with bladder tumors seen at the Department of Urology, Chosun University Medical School during the period from January. 1973 to December, 1979. The following results were obtained: 1. During that period. 820 patients were hospitalized and there were 53 cases of bladder tumors giving a rate of 6.5% 2. There were 32 males and 13 females a ratio of 2.5: 1 and 71. 1% of the patients was over 50 years of age. 3. The most common symptom was grose hematuria (82. 2%) and the others were frequent urination (35. 6%), dysuria (31. 1%), painful urination (22. 2%) and lower abdominal pain (22. 2%). 4. 22 cases (48.9%) of the patients visited the hospital within three months after the appearance of the initial symptom and 75.6% within 1 year. 5. 24 cases (53. 3%) had multiple tumors and 21 cases (46.7%) single tumor, Regardless of origin, lateral wall was involved in 30 cases (66. 7%) and the trigone in 20 cases (44.4%). 6. IVP performed in 43 cases revealed normal upper urinary tract in 27 cases (62. 8%) and filling defect of the bladder in 40 cases (93. 0%). 7. The pathologic examination performed in 37 cases revealed transitional cell carcinoma in 29 cases (78. 4%). 8. The operation was performed in 25 cases: Partial cystectomy in 11 cases open resection with coagulation in 3 cases, TUR in 5 cases, radical or simple total cystectomy in 6 cases and ileal diversion only is 1 case. 9. Of the 14 cases possible in follow up study 10 (71.4%) survived over 1 year after treatment.

BACKGROUND: Methods to detect and quanitify Mycobacterium leprae(M. leprae)are needed for studies involving the epidemiology, pathogenesis, and chemotherapy of leprosy. Serological assays and skin tests lack the sensitivity and specificity to serve as diagnostic tool for M. leprae infection. The polymerase chain reaction(PCR) based on the selective amplification of an 530-bp frangment of the gene encoding the proline-rich antigen of M. leprae was performed with sections of fixed or frozen biopsy samples from leprosy patients. OBJECTIVE: This study was done to investigate the applicability of PCR for the detection of low numbers of M. leprae in tissues and peripheral blood. METHODS: The PCR was used to amplify a 530-base-pair M. leprae DNA with the thermoxtable Taq DNA polymerase. RESULTS: The In frozen skin tissues and peripheral blood of leprosy patients. relatively high detection rates of PCR products was achieved by using direct gel analysis as well as Southern blot hybridization. CONCLUSION: These results suggest that PCR amplification for the detection of M. leprae may be useful for the epidemiologic study of large papulations as well as coinical astudies on the individual patients.

Proliferative vitreoretinopathy (PVR) is the main cause of failure in retinal reattachment surgery, Vitrectomy combined with pharmacologic therapy to inhibit proliferating and contracting epiretinal membranes appears to be a promismg approach in the management of PVR. We investigated the inhibitory effect of intravitreal 5-fluorouracil (5-FU) on experimental PVE induced by intravitreal injection of homologous dermal fibroblast in pigmented rabbits. At 6 weeks after intravitreal injection, Goup I (fibroblast only), Group II (early treatment with 1mg of 5-FU), and Group Ill (delayed treatment with 1mg of 5-FU) developed the retinal detachment in 85.7%, 33.3%, and 58.3% respectively. The rate of retinal detachment was lower in treatment groups than in non-treatment group, but there was a statistically significant difference only between non-treatment group (Group I) and early-treatment group (Group II) (p<0.05). In the group that only 5-FU was injected (Group IV), the retinas were preserved in normal clinically and pathologically. These results show that 5-FU may exert a significant anti proliferative effect on intraocular proliferative disorders including PVR especially if the drug is administered more earlier.

PURPOSE: The expression of matrix metalloproteinase-2 (MMP- 2) by cancer cells has been implicated in metastasis through cancer cell invasion of the basement membranes mediated by a degradation of collagen IV. However, the MMP-2 proenzyme requires proteolytic activation for its physiologic or pathologic role. We tried to 1) compare expression and activation of MMP-2 in breast cancers with benign tumors, 2) determine the correlation between the actviation of MMP-2 in breast cancer and established prognostic factors, 3) observe whether MMP-2 is expressed and activated in axillary lymph nodes as well, and 4) determine the degree of correlation between MMP-2 activity in lymph nodes and metastatic status, if MMP-2 is expressed in lymph node. METHODS: The specimens came from 11 fibroadenomas, 32 invasive ductal carcinoma and 129 axillary lymph nodes from cancer cases. Pro-MMP-2 cDNA transfected MDA-MB-231 cells were cultured and the conditioned media from them was used for a control. Zymography was used to monitor MMP-2 activation through the detection of the inactive proenzyme form (72 kDa) and the active form (62 kDa). Immunohistochemical staining was also performed for the localization of MMP-2 expression in tissues. RESULTS: 1) 72 kDa was expressed in all fibroadenomas and cancers, while 62 kDa was expressed in only 10 cases of fibroadenomas and all cancers. MMP-2 activity (62 kDa/72 kDa +62 kDa) was significantly higher in cancers than in fibroadenomas (P=0.014). 2) MMP-2 activity in cancers was significantly correlated with nodal metastasis (P=0.040). 3) The expression of MMP-2 in lymph nodes was very low and MMP-2 activity was not correlated with metastatic status. However, the immunohistochemical staining showed different staining patterns between the metastatic and non-metastatic nodes. CONCLUSION: We suggest that a measurement of the activation of MMP-2 could be useful as a prognostic marker representing metastatic potential in breast cancer. However, the low expression of MMP-2 in lymph nodes is an interesting subject for further study.
