Chordoma is relatively rare and slowly growing tumor arising from notochordal remnant. The tumor is locally infiltrative rather than metastatic. Distant metastasis occured in 5% of Gentil & Coley's cases and 43% of Higinbotham et als cases. Usual sites of metastasis sites were lung, liver adrenal gland and lymph nodes. In 1922, Stewart reported first case of extrapulmonary metastatic chordoma in muscle & subcutaneous layer, which was extremely rare. We have experienced a case of wide spread multiple metastasis to muscle & subcutaneous tissue from primary sacrococcygeal chordoma. The case was 26 years old man, who have had multiple metastatic lesions in trunk, upper & lower extremities. They located in muscle and subcutaneous fat layer. In some lesions neurovascular structure was involved. We have treated the metastatic lesions by complete surgical excision, and they were confirmed as soft tissue chordoma by histologic examination.

6-Phosphogluconolactonase (6PGL) is one of the key enzymes in the ubiquitous pathways of central carbon metabolism, but bacterial 6PGL had been long known as a missing enzyme even after complete bacterial genome sequence information became available. Although recent experimental characterization suggests that there are two types of 6PGLs (DevB and YbhE), their phylogenetic distribution is severely biased. Here we present that proteins in COG group previously described as 3-carboxymuconate cyclase (COG2706) are actually the YbhE-type 6PGLs, which are widely distributed in Proteobacteria and Firmicutes. This case exemplifies how erroneous functional description of a member in the reference database commonly used in transitive genome annotation cause systematic problem in the prediction of genes even with universal cellular functions.

Pseudocyst of the auricle presents as a non-inflammatory, fluctuant swelling on the upper half or third section of the ear, due to intracartilaginous accumulation of fluid. Histological examination shows an intracartilaginous cavity without an epithelial lining. The etilogy and pathogenesis of this disorder remains unknown, but the lesion is likely to be due to localized de-generation of cartilage. The degenerated cartilage is replaced by a vascular fibrous tissue from which there is serious exudation, and a clinical cystic swelling is formed. We describe in this report three cases of pseudocyst of the auricle, of which one was treated successfully by surgical excision and a pressure dressing, and the others by aspiration and steroid injection therapy. In all cases, the skin lesions had not recurred, and the patients were left with an excellent cosmetic result.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

BACKGROUND: There has been reports which suggest that non-specific symptom of patients with mitral valve prolapse is associated with autonomic dysfunction. METHODS: To assess autonomic dysfunction of patients, we examined five cardiovascular reflex tests in 25 asymptomatic MVP patients(identified as MVP group), 25 symptomatic MVP patients(identified as MVP syndrome group) and 25 control group. RESULTS: In the five cardiovascular autonomic function tests, abnormalities of Valsalva ratio were detected in 1(4%) control group, 7(28%) MVP group, 9(36%) MVP syndrome group, heart rate response to deep breathing in 0(0%), 2(8%), 4(16%) respectively, immediate heart rate response to standing in 0(0%), 2(7.4%), 2(8%) respectively and in postural hypotension, there were no abnormal group. Abnormalities of blood pressure response to sustained handgrip were only detected in 2(8%) MVP syndrom group. According to the five categories of cardiovascular autonomic functon tests, normal in 24(96%) and early damage in 1(4%) were detected in control group. In the MVP group, normal 17(68%), early damage 6(24%) and definite damage 2(8%) were noted. In the MVP syndrome group, normal 9(36%), early damage 13(52%), definite damage 1(4%) and combined damage 2(8%) were detected. In case of heart rate response to deep breathing, we found significant differences between control and MVP syndrome group(p=0.043), and between MVP and MVP syndrome group(p=0.0043). In case of heart rate response to standing, between control and MVP syndrome group(p=0.0009), between MVP and MVP syndrome group(p=0.001), the differences were noted. In case of blood pressure response to standing, between control group and MVP group(p=0.0019), between MVP and MVP syndrome group(p=0.0075), we found significant differences. Resulting from our study, heart rate response to deep breathing and standing, blood pressure response to standing were of considerable value in assessing the autonomic dysfunction of patients with mitral valve proapse. CONCLUSION: We found autonomic dysfunction in addition to increased autonomic tone and responsiveness which have been already known previously in mitral valve prolapse. And autonomic dysfunction was more severe in symptomatic patients with mitral valve prolapse than asymptomatic ones.

We analyzed 105 cases reports published in the Journal of the Korean Radiological Society between 1975 and 1985. The objectives of this study were to find out(1) whether those case reports were truly original or not as far as domestic pulications were concerned and (2) whether their citations of domestic literatures were correct. In two papers, we found previous reports published already in the domestic journal in spite of the authors' claim as their "first case reports". In 105 cases reports, only 94 references were cited while 151 omitted. It is concluded that a case report must include a statement to authentically clarify whether similar report had been previously published through meticulous review of published literatures. We also recommend to computerize the index domestic literatures.
