Many types of osteotomy have been proposed for the treatment of cubitus varus deformity of the elbow, and various methods for fixation of the osteotomy site have also been described. However, no method has been perfect. We treated two cases of cubitus varus elbow deformity with step-cut osteotomy using a new fixation method with two crossing screws and an anatomically designed locking plate. Active assisted elbow range of motion (ROM) exercise was permitted at postoperative 3 days, after removal of the drainage. Preoperative and postoperative humerus-elbow-wrist angles and ranges of motion of the two patients were compared. At 3 months follow-up, each patient had recovered the preoperative elbow ROM, and achieved the complete bony union of the osteotomy site and proper correction of the cubitus varus deformity. In addition, the appropriate remodeling of the lateral bony protrusion was observed. Therefore, we introduce a new fixation method for achievement of stable fixation allowing immediate postoperative elbow motion after corrective osteotomy for cubitus varus deformity in young adults.

Using immunohistochemical methods, the authors investigated the distribution of tubulin in normal skin and 31 skin tumors, including 11 benign skin tumors and 20 malignant skin tumors, In normal skin, tubulin was strongly expressed in basal cells of the epidermis, sebaceus celis and dermal nerves. Myoepithelial cells, ductalI cells of sveat ducts and outer root sheath cells of hair follicles stained moderat,ely. Lermal fi broblasts showed no staining. In benign tumors including keratoacanthoma, trichoepithelioma, and nevocellular nevus the strornal fibroblast.s were entirely tubulin negative as well as the turnor cells. In basal cell carcinoma, the stromal fibroblasts were negative',whereas tumor cells were weakly positive. In squarnous cell carcinoma(SCC), tumor cells weri, tubulin positive weakly, the degree of tubulin expression of its stroma1 fibroblasts tencied to be in proportional to the grade of malignanr.u. Tumor cells of malignant melanoma and nevocellular nevus were tubulin positive moderately bist the stromal fibrobla.sts were strongly positive only in the cases of malignant melanoma. These results show that the degree of the tubulin; expression in adjacent, stromal cells of epidermal tumors is in proportiona.l to that of their malignancy, These suggest that the expression of tubulin in fibroblasts surrounding tumor cells of malignant melanoma and SCC reflects a stromal alt,eration that might contribute to tumor in vasion, and play a role for cellular motility.

Fracture of capitellum humeri, so called Kocher fracture, was first described by Haln in 1853. It is rare and has been occured 0.5% to 1% of incidence of all elbow fracture. The mechanism of this fracture mostly results when one tries to break a fall and lands on the hand with the elbow in some degree of flexing or falls directly on the elbow in a position of full flexion. This case had been occured in a secondary motion

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.

The eccrine poroma was described first by Pinkus et al. in 1956 as a subgroup of benign solid hidradenoma with the histologic structure resembling acrosyringium. The histologic appearance of eccrine poroma greatly resembles that of seborrheic keratosis and basal cell carcinoma. But the clinical lesion is fairly unique and the tumor is most commonly found almost exclusively on the foot, in the skin of the plantar surface. During the past four years, the authors experienced five cases of eccrine poroma which were diagnosed by histopathological examination of the tumor mass. All the cases occurred in the sole and lateral sides of the foot as well. Clinical and pathological features were reviewed and a brief review of the literatures was done.

The rhabdomyosarcoma of the prostate is very rarely encountered in the western literature, and only a few reports have been published in Korea. The authours recently experienced two cases of rhabdomyosarcomas of the prostate in 35-year-old and 51-year-old males who had suffered from gross hematuria and difficulty of urination. Microscopic studies showed embryonal type of rhabdomyosarcoma in two cases. The clinical and pathological features of the distinctive prostatic rhabdomyosarcoma are described, and a brief review of the literature is made.

Compared with osteosarcoma of bone, primary osteosarcoma of the soft tissue is very rare. Extraskeletal osteosarcoma is also a highly malignant pleomorphic sarcoma composed of cells exhibiting primarily osteoblastic, and to a lesser extent, chondroblastic differentiation. A case of extraskeletal osteosarcoma in the right sole is presented in a 67 year old male. The patient had noticed a progressively enlarging soft tissue mass, during about 14 months. This sarcoma was located in the soft tissues without attachment to the skeleton, as determined by examination of the X-Ray findings. The mass of right plantar portion was simply excised and pathologically confirmed to be an extraskeletal osteosarcoma. The clinical and pathological features of this sarcoma are described, and brief review of the literature is made.

Crescentic glomerulonephritis in rheumatoid arthritis is described recently with increasing frequency. It can occur directly as a manifestation of rheumatoid arthritis or may be a reaction to drugs such as D-penicillamine and bucillamine. We report a case of crescentic glomerulonephritis in a 46-year-old woman with rheumatoid arthritis for 20 years who had been treated intermittently with herb medicine or nonsteroidal anti-inflammatory drugs (NSAIDS). Light microscopic examination showed severe focal segmental and global necrotizing glomerulonephritis with crescent formation in 50% of the glomeruli. Immunofluorescent study revealed scanty amount of mesangial granular deposits of IgA, IgM, C3 and fibrinogen in a diffuse pattern.
