Primary cutaneous monomorphous lymphoma is rare compared to the more usual involvement of skin secondary to internal monomorphous lymphoma. The histopathological diagnosis of the primary cutaneous monomorphous lymbhoma (PCML) requires differentiation from cutaneous lymphoid hyperplasia. The authors observed 3 cases of PCML. Case 1 was 21 year-old woman, who had an initial lesion on her left arm. Histopathologically it was diagnosed as poorly differentiated. lymphocytic lymphoma and was treated by surgical excision. Six months after onset she developed new lesions on her skin elsewhere, histopathologically diagnosed as well differentiated lymphocytic lymphoma. She died of infiltration of the bone marrow 19 months after the initial onset, even though combination of radiotherapy and chemotherapy resulted in clinical improvernent. Case 2 was a 70 year-old woman having an unusual cutaneous manifestation of an adult palm sized ulcerative, indurated tumor on her right forearm, histopathologically diagnosed as histiocytic lymphoma. There was no evidence of extracutaneous in volvement except right axillary lymphadenopathy. Case 3 was 72 year-old man, who had a clinical manifestation to that of case 2, histopathologically diagnosed as histiocytic lymphoma and received radiotherapy with good improvement. The patient did not show any evidence of extracutaneous involvement five months after the onset.

Papulonecrotic tuberculid (PNT) and Pityriasis lichenoides et varioliformis acuta (PLEVA) have been in controversy in their pathogeneses and entity itselves. Authors reviewed litera,tures of the two dermatoses with observation of nine casea of PNT from 1979 to 1981 and evaluated whether PNT could be also classified as PLEVA. The results were a,s follows: 1. By the review of literatures PNT and PLEVA showed great similarities in their clinical aspects including shape of cutaneous lesions, course, favorite age and subjecive symptoms. Histopathological overlappings were also found. 2. Of the nine cases of PNT authors observed, seven cases were histopathologically PLEVA and four cases could be thought PLEVA also clinically. But way six cases were treated by anti-tuberculous drugs. 3. The incidence of other tuberculous signs and results of tuberculin skin tests were all significant in the nine cases above. With the above observations it seems that PNT is one of the causes of PLEVA and thus could be a kind of PLEVA.

The patient, a girl of 19 years in good health, had a class I malocclusion. The maxillary left centra1 incisors and both lateral incisors had already erupted. But the space for the right central incisor was partially closed by the mesial drifting of the neighboring teeth. The caused a shift in the midline and a cross-bite relation on the incisors. X-ray examination revealed the presence of the right central incisor in the alveolar bone and odontoma just above the crown of the right central incisor. After enough space for the impacted incisor was created in the dental arch with a open-coil spring the rectangular incision was made. Removing the odontoma uncovered the flat surface of the labial aspect of the incisor. During the tooth had erupted of its own accord, any unnecessary force had been imposed on the tooth. When it was decided that the tooth should be brought out by the mechanical device, the gold cast onlay with hook was used and run a light elastic between this hook and the main arch wire. Finally the tooth was brought down to the arch level. The result was excellent. Fortunately the esthetic problem and any detrimental effects on the psychological make-up could be avoided.

PURPOSE: Abdominal CT scans in patients with intraperitoneal fluid were retrospectively studied to identify characteristic features useful for differential diagnosis of various causes. MATERIALS AND METHODS: One hundred and seventy patients with intraperitoneal fluid collection were classified as categories of hepatic disease, carcinomatosis, and infectious disease. We analyzed sites of fluid collection, the presence of peritoneal thickening, omental and mesenteric fat infiltration, and lymph node enlargment. RESULTS: Intraperitoneal fluid was present in subhepatic space, subphrenic space, paracolic gutter, mesentery, and fossa of the gallbladder in decreasing order of frequency. Fluid in the gallbladder fossa was the most frequent in hepatic diseases. The fluid collection in subhepatic and subphrenic space was less frequent in infectious diseases. Peritoneal thickening was noted in infectious diseases, and carcinomatosis. Omental fat infiltration and enlarged lymph nodes were the most frequent in carcinomatosis (58% and 44%, respectively), whereas, mesenteric fat infiltration and enlarged lymph nodes were the most common in infectious diseases (61%, and 26%, respectively). CONCLUSION: The location of peritoneal fluid collection showed some lesion specific characteristics, and CT features of fat infiltration and enlarged lymph nodes of peritoneum, omentum, and mesentery were helpful for differential diagnosis between carcinomatosis and infectious diseases.

Microsatellites are short nucleotide repeat sequences present throughout the human genome. Alterations of microsatellites, comprising extra or missing copies of these se quences, have been termed microsatellite instability(MSI, genetic instability, replication errors, RER(+) phenotype). To date, at least four genes involved in DNA mismatch repair, hMSH2, hMLH1, hPMS1 and hPMS2, are thought to account for the observation of microsatellite instability in tumor from Hereditary nonpolyposis colorectal cancer (HNPCC) patients. The genetic defect responsible for the MIN+ phenotype in sporadic colorectal cancer, however, has yet to be clearly delineated. The purpose of this study was to determine the presence of MSI in sporadic cancer and to correlate its occurrence with clinicopathological parameters, we have studied six microsatellite loci by use of polymerase chain reaction amplification and denaturing polyacrylamide gel electrophoresis. We found that 20%(9 of 46 cases) sporadic colorectal cancers showed RER at two or several loci(RER+). Microsatellite instability was associated with location of the tumor in the proximal colon 66%(6 of 9 cases) and with poorly differentiated tumor phenotype 56%(5 of 9 cases). In order to better understand the role of somatic alterations within hMSH2 in the process of colorectal tumorigenesis, we examined the most conserved regions(codon 598~789) of this gene in nine patients with MIN spotadic colorectal cancer. 6 patient of RER(+) colorectal ca. patients had a polymorphism which was a T to C base change in the intron sequence at -6 position of the splice acceptor site at the 5'end of exon 13. This particular sequence variation is a polymorphism rather than a mutation which increase cancer susceptability. These data suggest that the genetic instability is detect ed in some colorectal cancers and play an important role in the pathogenesis of sporadic colorectal cancer.

Traumatic atlanto-occipital dislocation is usually fatal. To date, few cases have been reported in the literature because survival after traumatic atlanto-occipital dislocation is extremely rare. We present the case of a 47-year-old man with traumatic atlanto-occipital rotatory posterior dislocation combined with atlanto-axial rotatory subluxation and treated by occipito-cervical fusion using Bohlman's triple wiring technique.
