1.Presence of Beta-2-microglobulin in Cutaneous Epithelial Tumors.
Korean Journal of Pathology 1986;20(3):322-327
The Beta-2-microglobulin is the part of light chain of human histocompatibility antigen (HLA). This protein can be observed in most of the human nucleated cells. Some of reports indicated that the Beta-2-microglobulin was lost completely or partially in the malignant or premalignant lesions. Observations on presence of Beta-2-microglobulin were made on 24 cases of malignant, premalignant and benign epithelial umors and 6 cases of normal or non-neoplastic epithelial lesions in the skin, using PAP method. The PAP method. 1) Normal epidermis and no-neoplastic cutaneous lesions (chronic non-specific dematitis, actinic change of skin with pseudoepitheliomatous hyperplasia) showed strong positive staining along the cutaneous epithelial cytoplasmic surface for Beta-2-microglobuin in all 6 cases. 2) Benign cutaneous tumors (keratoacanthoma, squamous cell papilloma and pigmented nevus) showed similar strong positive staining for Beta-2-microglobulin along the epithelial cell surface in 4 out 6 cases. Remaining 2 cases were out of 4 pigmented nevus, which showed weakly or pretty weakly staining. 3) Premalignant cutaneous lesions as solar keratosis showed generally weak positive staining along the epithelial cytoplasmic surface in all 4 cases. 4) Malignant cutaneous tumors (basal cell carcinoma, squamous cell carcinoma, Bowen's disease and malignant melanoma) showed mostly negative staining along the surface of epithelial cells for Beta-2-microglobulin, in 8 out of 14 cases. Remaining 6 cases showed slightly weak or patchy positive staining. As above observation, the presence of Beta-2-microglobulin in cutaneous epithelial lesions using PAP method could be indicated as one of good differential tool for histopathologic diagnosis in cutaneous malignant lesions.

The unstable pelvic fracture involving sacro-iliac joint produced by excessive force, is relatively rare but causes a multiplicity of complications and presents a major therapeutic problem. The clinical results were obtained as follows: 1. 9 patients out of 16 were in age group between 20 to 29 year, Male and female ratio was 5:3 2. 10 patients out of 16 were produced by traffic accident. 7 patients among 16 were included in vertical shear type and 5 in lateral compression type. 3. There were 44 associated injuries in 15 patients. Fractures in other region were the most common associated injury in 20 and injuries of the genito-uninary system in 8. 4. All of the cases were treated conservatively and their result were excellent or good except 1 patient in pelvic disruption type, who has had paraplegia due to fracture-dislocation of L4-5.

Giant cell tumor is a relatively uncommon neoplasm with high rate of local recurrence following curettage and bone graft. The histologic grading was not proven useful in predictiog outcome. Histologically benign giant cell tumor may metastasize. We report a case of histologically benign giant cell tumor occurred at left distai femur with local recurrences and multiple pulmonary metastases which was proven by percutaneous needle aspiration lung biopsy. Recurred local lesion was treated by curettage and filling with methylmethacrylate and pulmonary metastases was treated with adriamycine and dacarbazine.

Pigmented villonodular synovitis (PVNS) is a relatively rare condition. The disorder almost always involves a single joint and the knee is most commonly affected. We report on three cases of localized PVNS that involved the patella fat pad and synovium. Diagnostic and therapeutic arthroscopies were performed, and typical findings of localized PVNS were found. Complete resection of the lesions were performed arthroscopically. Arthroscopy can be used as an effective diagnostic and therapeutic tool for identification and resection of intraarticular localized PVNS of the knee.
