PURPOSE: To determine the necessity of site-specific bone mineral density(BMD) measurement and the difference between the BMD of the two femora using DXA in the evaluation of osteoporosis. MATERIALS & METHODS: Total BMD and regional BMD(Lumbar spine, femoral neck, Ward's area, intertrochanter area) were measured on seventy-eight healthy persons without previons diseases, and the statistical significance analyzed. RESULTS: Total BMD did not reliably reflect the site-specific BMD. There was a high correlation between BMD in opposing femora. Correlation coefficients between the femoral neck, Ward's area, trochanter area were 0. 939, 0.874 and 0.916 respectively. CONCLUSION: We conclude that a measuremnt of site-specific BMD is necessory because the total BMD can not reliably predict the regional BMD. The measurement of BMD in one femur can predict the BMD of the contralateral femur. If there is no history of femoral neck disease, unilateral BMD measurement is recommended for femoral evaluation.

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.

bcl-2 and c-myc protein expression were studied in 44 epidermal (8 seborrheic keratoses, 21 squamous cell carcinomas, and 15 basal cell carcinomas), and 26 melanocytic tumors(8 nevi, and malignant melanomas) by immunohistochemistry using the specific anti-bcl-2 and anti-c-myc monoclonal antibodies. 14 out of 15 basal cell carcinomas(BCC) (93.3%) showed expression of bcl-2 protein, 12 of which (85.7%) showed coexpression of c-myc protein. In the melanocytic tumors, 7 out of 8 nevi showed bcl-2 expression (87.5%). Five of these 7 cases (62.5%) also showed c-myc protein expression. Eight of 18 malignant melanomas(MM) (44.4%) showed expression of bcl-2 protein and 7 of these 8 cases (38.9%) also showed c-myc protein expression. All seborrheic keratoses and squamous cell carcinoma(SCC) were negative for bcl-2 proteins. 12 of 15 SCCs(80%) were positive for c-myc protein. In conclusion, bcl-2 and c-myc proteins were coexpressed in BCCs, nevi, and MMs. Coexpression of bcl-2 and c-myc proteins in these tumors was statistically significant(p<0.01), while no considerable differences of bcl-2 and c-myc expression were found between nevi and MMs. These results suggests that bcl-2 may cooperate with c-myc to promote tumorigenesis of BCCs, nevi, and MMs(p<0.01).

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.
