Sarcoidosis is a rare d:sease in Korea and its association with erythema nodosurn is even rarer. Recently we saw a patient of bihilar adenopathy, who had arthralgia and erythematous nodules of both lower legs. A skin biopsy obtained from the erythematous nodule of the lower leg showed septal panniculitis, consitent with erythema nodosum, and a biopsy from the mediastinal lymph node revealed a pathology consistent with sarcoidosis. This is the first case of Lofgrens syndrome confirmed by histology ir, Korea.

Replantation of a severed limb is an elective procedure and, as such, the decision to carry it out must be assessed anew in each case. The arm is progressively more valuable from shoulder to fingers, the leg, on the contrary, is progressively of less significance. Especially, the replantation of severed hand at the level of carpal bones or wrist joint is technically more difficult than at the level of forearm or arm. We have a successful case of replanted hand at the level of intercarpal joint without bony shortening.

Fibromatosis can occur at various sites, but intracranial fibromatosis is exceptionally rare. Here, we report a case of intracranial fibromatosis arising in the suprasellar area of a 52-year-old woman who had undergone a surgery at that site. A computed tomography scan revealed a heavily calcified, highly enhancing, poorly demarcated mass in the left sellar area that extended into the left suprasellar, parasellar areas, and orbital apex and completely encased the left distal inferior cerebral artery. Histologic and immunohistochemical features were compatible with those of fibromatosis, although the cellularity was focally higher than usual. The etiology of extra-abdominal fibromatosis is unknown, but physical injuries such as trauma and irradiation have been reported to be associated with its occurrence. Although fibromatosis is rare in the intracranial area, it should be considered as a differential diagnosis when an intracranial mass occurs at a previously injured site.

Fusariosis is a rare infectious disease caused by species of the genus Fusarium that has been increasingly documented as an emerging agent of opportunistic infections in immunocompromised patients and, occasionally, immunocompetent hosts. We describe an 18-year-old Korean male, previously diagnosed as acute lymphocytic leukemia, presented with 2~4 cm-sized erythematous to necrotic papulonodules on the trunk and extremities for a week. White blood cell count was 200 cells/L and biopsy specimen showed structures resembling fungal elements in the dermis and subcutaneous fat. Cultures from a biopsy sample growing whitish cottony colonies contained fusoid multiseptated macroconidia. He was diagnosed as fusariosis and treated with intravenous amphotericin B. But white blood cell count and clinical symptoms didn't improve and he was expired after 6 days of treatment.

Amyloidosis is a disease complex associated with deposition of insoluble filbrillar protein in various tissues of the body. Cutaneous lesions are present in up to 40 % of patients with primary and myeloma associated systemic amyloidosis. We present a case of systemic amyloidosis associated with multiple myleoma occuring in 54-year-old male who had waxy papules with petechiae on nasola bial fold, postauricular area, and cheek. The diagnosis was confirmed by Congo red stain, electron microscope, immunelectrophoresis, Bence-Jones proteinuria, immunoperoxidase stain, and bone marow biopsy.

Pilomatricoma is a rare benign neoplasm arising from hair follicular matrix cells and exhibiting slow growth. The radiologic features of this neoplasm have rarely been described in the literature; in particular, the ultrasonographic findings have not been published in Korea. We report a case of pilomatricoma presenting as a well-marginated soft tissue mass with calcification in the dermis and with overlying bullous skin, a rare clinical variant.

STATEMENT OF PROBLEM: Main consideration was given to the stresses at the site of implant entry into the cortical bone at the alveolar crest. As a suspectible factor affecting the occurrence of stress concentrations, the contact angle between the implant and the alveolar crest bone was addressed. PURPOSE: The purpose of this study is to evaluate angles between the alveolar crest bone and the implant effect on the implant crestal area induced stresses using a finite element method. MATERIAL AND METHODS: Cylindrically shaped, standard size ITI implants entering into alveolar crest with four different contact angles of 0, 15, 30, and 45 deg. with the long axis of the implant were axisymmetrically modelled. Alterations of stresses around the implants were computed and compared at the cervical cortical bone. RESULTS AND CONCLUSION: The results demonstrated that regardless of the difference of the implant/alveolar crest bone contact angles, stress concentration occurred at the cervical bone and the angle differences led to insignificant variations in stress level.
