We describe cytologic findings of two cases of pilomatrixoma which had been cytologically misdiagnosed as suspicious malignant and malignant lesions in 35 year-old and 22 year-old females who presented a palpable neck mass. The cytologic smears showed many basaloid cells with a high nuclear-cytoplasmic ratio, nuclear hyperchromatism and prominent nucleoli, keratinized squamous cells with pyknotic nuclei, foreign body giant cells, and chronic inflammatory cells in necrotic background. Retrospective view of this aspiration smear revealed that these findings were characteristic features of pilomatrixoma, and the evenly distributed chromatin pattern as well as the lack of nuclear pleomorphism were considered to be the differential points from malignant neoplasm. Pilomatrixoma is a benign neoplasm which should be included in differential diagnosis if the fine needle aspiration cytologic smear of a neck mass or subcutaneous mass of any site showed these features.

Venous thromboembolic disease is a frequent complication after total hip arthroplasty. However, in Korea, the low incidence of deep vein thrombosis after total hip arthroplasty was reported. In this study, we present the results of 82 consecutive patients(90 hips) who had a cementless total hip replacement with a Anatomic Medullary Locking Component(AML: Depuy, Warsaw, Indiana, USA) between August 1995 and September 1996 at Inha University Hospital, Korea. Postoperatively, none of the patients were treated with any known prophylatic method for deep vein thrombosis except elastic stockings. Both preoperatively and six weeks after surgery, all patients were studied by an radiologist using a portable Doppler ultrasonic velocity detector with a transmission frequency of 5 megahertz. Contrast phlebography was also done in all patients at the same time as the Doppler ultrasound. In addition, coagulation assays, a complete blood count, blood typing, and serum chemical-profile tests were done for all patients. In comparing the results of these laboratory tests from the DVT group and from the non-DVT group, we found that only eight patients(9.8%) out of eighty-two patients had DVT after total hip arthroplasty. Thrombi were found in the superficial femoral vein in five cases and in the common femoral vein in three cases. Though two(2.4%) patients showed suspicious symptoms of pulmonary embolim, their perfusion lung scans were negative. The DVT group show a significantly shorter activated partial thromboplastin time than did the non-DVT group(P<0.05). In addition, the DVT group showed significantly higher serum total protein than the total protein level of the non-DVT group(P<0.01). In this two groups, there was no difference between the results of Doppler ultrasound and the results of contrast phlebography. Consequently, the incidence of deep vein thrombosis after total hip replacement arthroplasty in Korean patients is significantly lower than incidence in patients from countries other than Korea. Doppler ultrasound was a non-invasive and the most reliable diagnostic technique for deep vein thrombosis.

Purpose: The purpose of this study was to evaluate the clinical and radiological results of total hip arthroplasty using a proximal modular femoral stem in patients who had secondary coxarthrosis associated with a deformed femur. Materials and Methods: Forty-two patients (45 hips) with secondary coxarthrosis were evaluated after primary total hip arthroplasty using an S-ROM proximal modular femoral stem, between January 2001 and March 2004. The average follow-up was 44 months (range, 24 to 60 months). The mean age of the patients was 48.5 years old and there was a predominance of female patients (65.5%). The preoperative diagnoses included 26 cases of developmental dysplasia of the hip, 13 cases of sequalae of LCP, 2 cases of epiphyseal dysplasia, 3 cases of sequalae of pyogenic arthritis, and 1 case of congenital coxa vara. Results: The average Harris hip score improved from 52.2 points to 85.5 points. All the femoral stems demosntrated stable fixation, which included 37 cases by bony ingrowth and 8 cases by stable fibrous ingrowth. Neither osteolysis nor progressive radiolucent lines around the femoral stems were found at the latest follow-up. Postoperative complications included: 2 cases of hip dislocations, 1 case of periprosthetic fracture, 1 case of infected cup loosening, and 1 case of sciatic nerve palsy. Overall, forty-one hips (91.9%) exhibited excellent or good clinical results at the most recent follow-up. Conclusion: For advanced secondary coxarthrosis, total hip arthroplasty with use of a proximal modular femoral stem yielded good mid-term results based on clinical and radiological criteria.

The development of the microvascular surgery revolutionalized the reconstructive surgery of the lower ext tremity. Especially, the defects of the heel and sole, the weight bearing area, were quite difficult and complicate to reconstruct by conventional methods. Many papers reported successful resurfacing the heel pad by free cutaneous or myocutaneous flaps. However, only few reports were conceming the late results of the reconstructed free flaps. The authors studied the histological and histochemical changes of the free flaps under the weight bearing stress in 10 cases. 1. The authors reconstructed 10 cases of the heel pad defects by dorsalis pedis free Aaps (5 cases) and latissimus dorsi myocutaneous flaps(5 cases). 2. Before transfer, the homy layer was very thin(about 0.16–0.2 mm) and had an arrangement of basket-weave pattem in both flaps. Until one year after transfer, this layer was wom out (0.02–0.08mm) However, after one year, this layer became thick (0.05–0.7 mm) and the arrangement was compact in both free flaps. 3. The granular and prickle cell layers were also increased in thickness after one year. 4. In the suprabasilar area, friction blisters were observed before one year, especially in latissimus dorsi myocutaneous flap. However, they slowly disappeared after one year and then the epidermis was stabilized. 5. In the dermis, the contents of the amyloid and acid mucopolysaccharides were increased up to the level of those of the normal heel pad in both flaps. 6. As a conclusion, the transferred free flaps were in distress before one year. But after one year, they began to adapt well histologically and histochemically to the weight bearing stress.

We report a case of sarcoidosis in a 4-year-old girl. She showed the involvements of the skin and eye, which are the characteristics of sarcoidosis in very young patients, and also showed an unusual finding of hepatosplenomegaly. Because the diagnosis of childhood sarcoidosis is difficult and serious sequelae can develop from sarcoidal uveitis, an early skin biopsy and regular ophthalmologic assessment are essential.

Cutaneous metastasis from parotid gland carcinoma is very rare and there have been no re-ports in Korean literatures. Furthermore, it can often manifest as inflammatory type of skin metastasis and mimic a radiodermatitis. We report a case of a 31-year-old Korean man with cutaneous metastasis originated from parotid gland mucoepidermoid carcoinoma which mimicked clinically a radiodermatitis.

Cutaneous mesenchymal hamartoma (CMH) is a very rare disease which most often presents itself at birth and is composed of collagen fibers, immature fibroblasts, fat cells, blood vessels, and mast cells. Until recently, only two cases have been reported. Thus, the clinical and histopathological findings have been unsettled. We describe three cases of cutaneous mesenchymal hamartoma with different clinical findings, discuss its pathogenesis, and suggest that CMH is a distinct disease entity.
