Ichthyosis hystrix is characterized by extensive bilateral systemic involvement of thick hyperkeratotic verrucous papules forming confluent plaques or linear arrangement and is currently classified into a systematized epidermal nevi, which was once conaidered as an extreme variant of congenital ichthyosiform erythroderma. Here is presented a case with typical clinical features and characteristic histopathologic findings of epidermolytic hyperkeratosis. Our patient exhibited no skeletal or CNS abnormalities reported to be associated with this condition. Marked improvement was obtained with oral administration of etretinate.

We reviewed 40 cases of femoral shaft fractures in children treated with split Russel traction and initial fracture angulation above 10 degree. The treatment of femoral shaft fractures in children is various according to age. Satisfactory results have been reported with split-Russel traction. At an average follow-up of 33 months, we obtained following results about remodelling of fracture site & physeal site, possible acceptable angulation of fracture. 1. The average time of traction was 18 days, and hip spica cast was applied for 28 days. 2. Malunion within 25degrees in flexion & 23degrees in valgus & 24degrees in varus was well corrected spontaneously. 3. Average correction of initial angular deformity was 86% at last follow up. 4. Anterior angulation was corrected at 83%, varus 87%, valgus 88%. 5. Remodelling according to direction of deformity was no statistical correlation (P>0.05), and then spontaneous correction of angular deformity was same without relation to direction of deformity. 6. Remodelling according to site was statistical correlation (P<0.05), fracture site 26%, physes 74%. And proximal physes 36%, distal physes 38%.

Rheumatoid arthritis is considered to be a collagen disease which mainly involves articular structures, sometimes has extraarticular manifestations. It is generally accepted now that periarticular osteoporosis develops in early phase of rheumatoid arthritis and generalized osteoporosis in late period. Of several methods of non-invasive measurement of bone mass, single photon absorptiometry was introduced by Cameron and Sorenson(1963) and it has been used for measuring bone mass by many authors with its precision, reproducibility and objective quantification. We tried to observe the quantitative changes of bone mass in rheumatoid arthritis patients with single photon absorptiometry technique. Through the study of bone densitometry in 30 rheumatoid arthritic women compared with age-matched 60 healthy controls, we obtained follow results. 1. Bone mineral density of the rheumatoid arthritis group was lower than that of the control group, but had no significant statistical difference. 2. Bone mineral density of the 40–49-year-old group and 50–59-year-old group was considerablely different in the rheumatoid arthritis group and control group. 3. Bone mineral density of the group whose rheumatoid arthritis history was over 2 year was lower than that of the group below 2 year.

Ultrasonography is suited for screening patients with a mass in the soft tissue because of its safety, low cost, apparent sensitivity and non-invasiveness. But the application in orthopaedic surgery is insufficient. Authors examined 102 patients who had a palpable soft tissue mass of extremities and trunk with ultrasonography. Location, internal echogenicity, margin, and extent of soft tissue involvement, especially neurovascular bundle by tumor were evaluated. The diagnosis of mass was confirmed by histopathology after excision or biopsy of the mass. The ultrasonography correctly identified and differentiated the cystic lesions of 34 cases. The sonograms of all 16 malignant lesions showed ill-defined margin and heterogenous internal echo. The extent of soft tissue involvement, especially neurovascular bundle was confirmed exactly with ultrasonography. Therefore, in malignant tumor, after confirmation of no neurovascular involvemment with ultrasonography, limb-salvage operation could be considered and planned. In one case of abscess, percutaneous biopsy was done under guidance of ultrasonography. Therefore, ultrasonography can be used as a guide for percutaneous biopsy without exposure to radiation.

We report a 33-year-old woman with a 1-year history of typical skin features of dermatomyositis without any evidence of muscle involvement. Her skin eruption of the face (heliotrope erythema) and hands (Gottron's papules) and skin biopsy findings were typical of dermatomyositis. Levels of serum muscle enzymes were within normal ranges and electromyography showed no signs of muscle involvement. During a 1-year follow-up, she had no signs of muscle weakness. Based on these clinical and laboratory findings, our case can be diagnosed as amyopathic dermatomyositis.

Subepidermal calcified nodule, a form of idiopathic calcinosis cutis, typically present as a hard, 3 to 11 mm, solitary lesion on the exposed area of the head and the extremities. Here we re-port an unusual case of subepidermal calcified nodule occurring on the buttock. A 15-year-old girl presented with a 6-month history of a 12 × 6 mm, oval, hard, erythematous nodule on the right buttock. Histopathologic examination of an excision biopsy specimen revealed extensive deposition of calcium in the whole dermis as large multilobulated masses.
