Disibling pansclerotic morphea, a severe form of generalized morphea, has a relentless clisabling course, producing marked contract,ion and joint deformity due to sclerosis of the skin and the deeper structures. We report herein an unusual case of morphea in a 25 year old male who had suffered from chronic recurrent ulceration with scar like sclerotic changes overlying limb folds, ankles, nape and abdomen since 4 years of age. The indurated lesions on the chest and abdomen were ivory colored, sclerotic guttae and plaques having a, violac ous border. At l4 years of age, the skin lesions were diagnostically ambiguous, wherea.s the immunologic results revealed a selective IgA deficiency with partial T lymphacyte inactivation. About 10 years later, the follow up visit showed this severe form of morphea over generalized area and disabling contractures of knees, elbows and alkles, but IgA value returned nearly to the nomal level.

We report herein a case of elephantiasis neuromatosa seen in neurofibromatosis patient, who was a 33-year-old male and had been diagnosed at the age of 13. Since that time on, small nodule present on the mid-back area led to develop grotesquely large, dark-brown colored, flabby mass with thick verucoid skin change, measuring about 30 * 20cm in size. Histopathologic examination of excised mass demonstrated moderate hyperplasia of epidermis and typical neurofibroma findings with soft tissue and fibrous tissue overgrowth, but no atypical cells. The electron microscopic study showed many perineurial cells surrounded by the continuous bssal lamina of fibroblsst in the dermal lesion and numerous giant pigmented granules in melanocyte and basal keratinocyte in the cafe-au-lait spot.

BACKGROUND: The purpose of this study is to evaluate the functional outcomes of reverse total shoulder arthroplasty (RTSA) and to assess factors affecting the patients' subjective satisfaction after RTSA. METHODS: Forty-three patients (mean age, 75.0 ± 5.2 years) who underwent RTSA for cuff tear arthropathy or irreparable cuff tears with preoperative magnetic resonance imaging and pre- and postoperative radiographs at 1 year, and whose various functional outcomes including pain visual analogue scale (VAS), simple shoulder test, Constant score, American Shoulder and Elbow Surgeons score, and active range of motion were evaluated preoperatively and at the last follow-up (>12 months) were enrolled. The outcome parameter was set as a satisfaction scale. Various clinical and radiographic factors were analyzed, and their correlations with postoperative satisfaction were evaluated. RESULTS: All functional scores, VAS pain score, and active forward flexion showed significant improvement after surgery (all p<0.001). Twenty-nine patients were satisfied with the results and 14 were dissatisfied. The presence of pseudoparalysis (p=0.028) and worse preoperative function (all p<0.05) were related with higher satisfaction. Any radiologic parameters did not affect patients' postoperative satisfaction. CONCLUSIONS: All patients showed a good functional outcome after RTSA, however the patients' subjective postoperative satisfaction was affected by preoperative functional status (higher satisfaction in poor preoperative function), not by radiological findings.

PURPOSE: The purpose of this study is to describe the anglographic findings of collateral vessels in cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of anglographic assessmant needed before embolization. MATERIALS AND METHODS: We retrospectively reviewed 10 cervicofacial vascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous realformation with carotid cavernous fistula. The previously ligated arteries are proximal external carotid artery (n=5), branches of external carotid artery (n=2) and common carotid artery (n=3). Common carotid artery or internal carotid artery (n=9), vertebral artery (n=5), ipsilateral external carotid artery (n=4), contralateral external carotid artery (n=5), costocervical trunk (n=2), thyrocervical trunk (n=2) were assessed by conventional angiography. Angiography of both carotid and vertebral arteries was performed in 5 cases. RESULTS: The collateral vascular channels were inferolateral trunk of internal carotid artery (n=8), vertebral artery (n=5), contralateral external carotid artery (n=5), ipsilateral external carotid artery (n=4), deep cervical artery (n=2) and ascending cervical artery (n=l). Embolizations were performed in 9 cases with operative cannulation(n=4), embolization via collateral branches of ipsilateral external carotid artery (n=l), embolization via collateral branches of contralateral external carotid artery (n=3) and balloon occulusion via direct puncture (n=l). CONCLUSION: The collateral channels in cervicofacial vascular lesions with previouly ligated carotid artery were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervical artery and ascending cervical artery on angiography. Complete anglographic assessment of possible collateral channels is mandatory for the effective and safe embolization.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.
