A 38-year-old man presented with a black pigmented patch overlying his upper lip, a part of the gingiva and the hard palate. An intradermal tumor mass was palpated at the central portion of the pigmented patch of the upper lip. Diphenylcyclopropenone (DPCP) is a potent contact sensitizer that could stimulate non-specific immunity. We report a case of desmoplastic malignant melanoma (DMM) in which an atypical lentiginous pigmentation disappeared with topical DPCP immunotherapy and the dermal tumor mass was removed by a surgical wedge-shaped excision. Though an atypical lentiginous pigmentation of DMM sometimes undergoes extensive spontaneous regression, in our case it could be attributed to the therapeutic effect of topical DPCP immunotherapy rather than a spontaneous regression.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

BACKGROUND: Human cancel can be induced by various environmental factors such as virus, chemicals, and radiations. However, susceptibility of host to these environmental factors is not well studied. The purpose of this study was to investigate the chromosomal vulnerability to gamma-1rradiation of peripheral blood lymphocytes in patients with luring, gastric, and liver cancer. METHODS: Micronuclei (MN) test was done in 15 patients with gastric cancer, 18 patients with lung cancer, and 20 normal controls. Sister chromatid exchange (SCE) test was done in 13 patients with hepatocellular cancer and 14 normal controls. RESULTS: The baseline frequency of MN before irradiation in patients with lung cancer and gastric cancel was significantly higher than in controls (47+/-8, 73+/-9, and 8+/-l, respectively; p<0.01). After gamma-irradiation, the frequency of MN was also significantly higher than in controls (223+/-19, 269+/-43, and 285+/-56, respectively; p<0.05). The frequency of SCE in Patients with hepatocellular cancer was significantly higher her than in controls (9.0+/-0.6, 4.3+/-0.7, respectively; p<0.001). CONCLUSIONS: From this preliminay data, we concluded that chromosomes of peripheyal blood lymphocytes in patients with various cancers were more vulnerable to gamma-irradiation as compared to normal controls.

PURPOSE: To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma. MATERIALS AND METHODS: Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, total hysterectomy, salpingo-oophorectomy and lymphadenectomy were performed on the patient's pelvis. Total dose from 50.4 Gy to 63 Gy was irradiated at pelvis or extended field. Thirteen patients were treated with Co-60 or Ir-192 intracavitary radiotherapy. Follow-up periods were from 7 to 270 months, with a median of 56 months. RESULTS: Five year overall survival (OS) rate was 58.7%, respectively. Five year disease-free survival (DFS) rate was 59.2%, respectively. In univariate analysis for OS and DFS, stage, menopausal age, type of operation, serosal invasion, and lymph node involvement were found to be statistically significant. Histologic type was marginally significant. In multivariate analysis for OS and DFS, stage, types of operation, histologic type were also found to be statistically significant. Treatment failure occurred in 14 patients. The main pattern of failure was found to be distant metastasis. Time to distant metastasis was from 3 to 86 months (median, 12 months). There were no grade 3 or 4 complications. CONCLUSION: Stage, types of operation, and histologic type could be the predictive prognostic factors in patients. We contemplated postoperative radiation as effective and safe treatment method for EC. Additional treatment would be needed to reduce distant metastasis.

Cornelia de Lange Syndrome (CdLS) is a multiple congenital anomaly characterized by distinctive facial features, upper limb malformations, growth and cognitive retardation. The diagnosis of the syndrome is based on the distinctive clinical features. The etiology is still not clear. Mutations in the sister chromatid cohesion factor genes NIPBL, SMC1A (also called SMC1L1) and SMC3 have been suggested as probable cause of this syndrome. We experienced a case of newborn with CdLS showing bushy eyebrows and synophrys, long curly eyelashes, long philtrum, downturned angles of the mouth and thin upper lips, cleft palate, micrognathia, excessive body hair, micromelia of both hands, flexion contracture of elbows and hypertonicity. We detected a NIPBL gene mutation in a present neonate with CdLS, the first report in Korea.

Hirsutoid papillomas of vulvae present as smooth or filiform papules located on the inner surfaces of the labia minora. This disease is usually considered as anatomical variants of the vestibular mucosa. Differentiation from condyloma acuminata is important to avoid unnecessary treatment. Herein we report a case of hirsutoid papillomas of vulvae in a 21-year-old female who complained of pruritic papules on the vulva of one year's duration. Papules were located on the inner surfaces of the left labia minora and vestible of the vulva. Clinically, they were quite similar to condyloma acuminata. Histologically, however, the epithelium was devoid of features of human papillomavirus(HPV) infections such as koilocytosis, double nucleation, and dyskeratosis.

OBJECTIVE: The aim of this study is to ascertain the differences in NF-kappaB (Nuclear Factor-kappa B : p50) activity between the placental tissues of preeclampsia and normal pregnancy, and to certify that the circulating lipid peroxides is increased in preeclamptic women. METHODS: Placental tissues were obtained from preeclamptic (n=33) and normal pregnancies (n=21) with no other medico-surgical illness or obstetric complications, delivered by cesarean section without labor. The activities of NF-kappaB and IkappaBalpha (Inhibitory factor kappaBalpha) on syncytiotrophoblast, cytotrophoblast, endothelium, extravillous cytotrophoblast, and decidua were separately measured by immunohistochemical staining using tissue microarray technique. Malondialdehyde assay was used to evaluate the oxidative stress, measuring lipid peroxide levels on each sample. Mann-Whitney test was done for statistical analysis of the data. RESULTS: Nuclear staining of NF-kappaB (p50) was seen more intensively within the extravillous cytotrophoblast of preeclampsia group compared with the control group (p<0.05). The immunoreactivity of NF-kappaB (p50) was also detected in cytotrophoblasts, syncytiotrophoblasts, endothelium, and decidua, but showing no statistical difference between two groups. IkappaBalpha was strongly expressed in both groups but there was no statistically significant between two gropups. Preeclamptic group showed significantly increased circulating lipid peroxide levels compared to normal pregnancy group (1.22+/-0.79 nmol/mL vs 0.41+/-0.12 nmol/mL, p<0.05). CONCLUSION: The expression of NF-kappaB is significantly increased in extravillous cytotrophoblast of preeclamptic women compared to normal pregnancy, and may be associated with increased levels of circulating lipid peroxide. These findings might help us to understand the pathologic mechanism of preeclampsia and further study should be done for effects of NF-kappaB on implantation.
