Fibrohistiocytic tumors are a diverse group of benign and malignant soft tissue lesions, including dermatofibroma, dermatofibrosarcomaprotuberans, and malignant fibrous histiocytoma. On the clinical point of view, the distinction between benign and malignant lesions and malignancy grading is far more important. Therefore, we investigated 23 fibrohistiocytic tumors, using PCNA (PC10) which was a useful marker of proliferating activity, to differentiate the benign lesions from the malignant and correlate with other prognostic factors including tumor necrosis. cellularity, histologic grade, and mitotic counts. The results obtained were as follows 1) Positive tumor cells were clearly identified by the characteristic diffuse or granular nuclear staining. 2) The number of PCNA-positive tumor cells were 2.16+/-2.39% in dermatofibroma, 16.12+/-7.38% in dermatofibrosacoma protuberans, and 28.02+/-17.47% in the malignant fibrous histiocytoma. The numbers of PCNA-positive tumor cells in the malignant lesions higher than in the benign (p<0.001). 3) Deep seated, large size (>5 cm) and recurred or metastatic cases of MFH were more the high PCNA index (more than 20%) than the low index (less than 20%) groups. 4) PCNA index in MFHs had positive correlation with the number of mitotic counts (r=0.7582, p<0.001), cellularity (r=0.5908, p<0.05) and histologic grade (r=0.4164, p<0.05). These results suggested that reactivity on PCNA might assist in the distinction between benign and malignant lesions in fibrohistiocytic tumors, and could be a useful prognostic factor in the patients with malignant fibrous histiocytoma.

To evaluate the differentiation status of smooth muscle in gastric stromal tumors which were negative for S-100 protein, immunohistochemistry using desmin, actin, myosin and vimentin was performed in 14 cases of gastric smooth muscle tumors. Ultrastructural Examination was also performed. For comparison a case of leiomyoma of the esophagus, a case of the sigmoid colon, 10 cases of the uterus were also examined. The results obtained were as follows. All gastric smooth muscle tumors showed vimentin-positivity. Six of 14 gastric smooth muscle tumors, (5 of 8 leiomyoma and 1 of 4 leiomyosarcoma) showed positivity for desmin, actin, and myosin(42.9%). All esophageal, colonic, and uterine leiomyomas showed diffuse positive reaction for desmin, actin, and myosin. Vimentin positivity was also noted in leiomyoma of the colon and uterus. Ultrastructurally, a few cells in the gastric stromal tumors had scattered microfilaments with dense bodies, subplasmalemmal dense plaques, and micropinocytic vesicles. However, most of the tumor cells did not have any of the ultrastructural features of smooth muscle differentiation. Leiomyomas of the esophagus and uterus showed many cytoplasmic microfilaments with dense bodies. These results suggest that most of the benign and malignant tumor cells of gastric stromal tumors have features of the undifferentiated cells, immunohistochemically as well as ultrastructurally, although a few cells have. It is speculated that most gastric stromal tumors may have lost their smooth muscle differentiation.

The purpose of this study was to develop the CORE Program for sex offenders and to determine its effectiveness. The CORE Program was designed with an aim to achieve cognitive restructuring, improve the ability to empathize in interpersonal relationships, and enhance self-esteem and intimacy. We conducted this program over 48 sessions for 28 sex offenders. The effectiveness of the program was evaluated using the Interpersonal Responsiveness Index (IRI), Self-esteem Questionnaire (SEQ), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), Rape Myth Acceptance Scale (RMAS), and Wilson's Sex Fantasy Questionnaire (WSFQ). The data were analyzed using paired t-tests. Our results showed no significant changes in the SEQ, UCLALS, and IRI scores after the treatment program. However, the scores for the CUSI, RMAS, and WSFQ significantly improved after this program. In this paper, we demonstrate the effectiveness of the CORE Program for sex offenders. We also discuss the limitations of our study and provide suggestions for future research. Our findings indicate that this treatment program should be provided to sex offenders for preventing recidivism.

Adenosquamous carcinoma of stomach is a mixed glandular-epidermoid tumor where both components are neoplastic. Its incidence is extremely rare. The five theories on the origin of squamous components are 1) island of ectopic squamous epithelium in the gastric mucosa, 2) squamous metaplasia of gastric epithelium, 3) squamous differentiation in a preexisting adenocarcinoma, 4) endothelial cell differentiated toward squamous elements, and 5) totipotential undifferentiated cells of the gastric mucosa. We experienced three cases of adenosquamous carcinoma. Case 1 was a 71-year-old female patient; an ulcerative lesion was present in the pylorus, measuring 5 cm in diameter. Case 2 was a 57-year-old male patient; an ulcerative lesion is present in the pylorus, measuring 6 cm in diameter. Case 3 was a 58-year-old female patient; an ulcerative lesion was present in the body and fundus, measuring 10 cm in diameter. Microscopic examination revealed a mixed malignant squamous and adenomatous component.

Lichen planopilaris is believed to be a variant of lichen planus which is occasionally accompanied by classical lichen planus. A 68-year old male had asymptomatic skin colored or light violet colored papules and nodules on the occipital area followed by hair loss for 2 months. He had also violaceous pea to bean sized whitish scaly papules on the right lower extremity. Histopathological examination revealed the dilated follicles to be filled with horny material. There were also intense infiltrations of monocytes which were most prominent at the lower pole of the hair follicles on the scalp lesion. There was also hyperkeratosis, focal hypergranulosis and band-like infiltrations of lymphocytes at the dermo-epidermal junction on the lesion of the lower extremity. Direct immunofluorescence examination showed linear deposition of fibrin at the dermo-epidermal junction in the hair follicles. We had an opportunity to observe a man with lichen planopilaris who had loss of scalp hair which was accompanied by classical lichen planus on the lower extremity.

The purpose of this study is to obtain the clinicopathological characteristics of replication error-positive (RER ) gastric adenocarcinoma in Korean, and to identify the significance of RER in adenoma stage of gastric carcinogenesis. Microsatellite instability was examined at D2S71, D2S119, D3S1067, D6S87, D11S905, DM, AR, VWF, HPRT, and BAT-26 loci. Frameshift mutation of BAX gene was analyzed in RER tumors. Normal and tumor DNA of 76 cases of gastric carcinoma and 25 cases of adenoma were examined. RER was found in 8 of 76 cases (10.5%), and it was more frequently found in adenocarcinoma of female (17.7%) than those of male (4.8%). The frequency of RER was not different between the histologic types, age of the patient, anatomical location of the carcinoma, and the stage. The RER found in adenoma suggests that RER contributes to the malignant transformation early in the adenoma stage of the gastric carcinogenesis. None of the RER tumors revealed frameshift mutation of the BAX gene.

Eosinophilic gastritis is a rare disease that is characterized by eosinophilic infiltration of the bowl wall tissue, and the presentation of symptoms varies depending on the affected site. It is likely that eosinophil-active cytokines play important roles in this disease. A 22-year old man presented with abdominal pain and vomiting. Endoscopic gastric biopsy revealed eosinophilic infiltration, and the serum level of Interleukin (IL)-5 was increased. Gastric emptying was moderately delayed in this patient. The patient was treated with steroid and he showed dramatic clinical improvement with disappearance of the eosinophilic infiltration of the gastric mucosa, normalization of the serum level of IL-5 and improvement of the gastric emptying time. There has been few case reports of eosinophilic gastritis that have described the change of the serum level of cytokines and the gastric emptying. We report here on a case of eosinophilic gastritis and the patient showed elevated serum level of cytokines and delayed gastric emptying. The patient improved after being treated with steroid.

Short stature homeobox-containing gene (SHOX) is a well-known causative gene for the short stature in Turner syndrome. The clinical manifestation of SHOX gene related disorders varies from SHOX haploinsufficiency, presenting with idiopathic short stature, disproportionate short stature, or Leri-Weill dyschondrosteosis (LWD) to recessive form of extreme dwarfism and limb deformity in Langer mesomelic dysplasia. LWD is usually diagnosed upon suspicion based on short stature and skeletal abnormalities, and it is rarely accompanied with respiratory failure in the neonatal period. Here, we report the case of a newborn infant with LWD presenting with severe micrognathia that caused respiratory distress, which was diagnosed using microarray testing. Even when the manifestation of Madelung deformity is not yet apparent, LWD should be considered as one of underlying diseases related to congenital micrognathia.
