Intracranial nerve sheath tumors unrelated to the cranial nerve roots are extremely rare, and the origin of the tumors are debatable. We report a case of pathologically-proven neurofibroma inside the lateral ventricle. A 49-year-old man presented with headache of 6 months duration, urinary incontinence, visual disturbance and right hemiplegia. Brain CT scan showed a well defined isodense mass with homogenous contrast enhancement and marginal calcification. At surgery the tumor was found to be a 4cm-sized lobulated mass attached only to the choroid plexus. Histologically, the tumor masses consisted of fasciculating bundles of wavy spindle cells, with a considerable collagen laydown.

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

Fingerprints have been used for personal identification, for revealing physical anthropological characteristics, and for diagnosing genetic disorders. Morphology of fingerprints has been analyzed in various tribes. However, in Korean, the analytical methods of fingerprints and the numbers of subjects were not sufficient to find standard values for Korean fingerprints. In this study, fingerprints of 3216 Koreans (2095 males and 1121 females) were analyzed using the various methods and compared with those of other tribes to contribute in revealing physical anthropological characteristics of Korean and also in diagnosing genetic disorders of Korean. The results were as follows. 1. The incidence of ulnar loop type, whorl type, radial loop type, and arch type was 50.4%, 42.9%, 3.8%, and 2.9%, respectively. Data from the comparison of the incidences of fingerprint types in Korean with those in various tribes lead us to conclude that Korean belongs to the Asians and becomes closer to the Whites and Blacks in which loop type is frequent and whorl type is not frequent. 2. Fingerprint type seems to be related to the strength of finger since whorl type was frequent in male and in right hand, and arch type was frequent in female and in left hand. In addition, loop of fingerprint appears to have the tendency to open to the side bearing more physical contact since radial loop type was frequent in second finger, and ulnar loop type was frequent in fifth finger. 3. Among the subtypes of fingerprint, morphologically simple types were common. Among the subtypes of arch types, simple arch type with the same number of radial dermal ridges as ulnar ones was the most common. Among the subtypes of loop types, ulnar loop type without concentric circles or spirals was the most common. Among the subtypes of whorl types, concentric whorl type without loops was the most common. 4. Finger ridge counts were 16.9, 13.9, 11.9, 11.3, and 11.2 in first, fourth, third, second, and fifth finger, respectively; and were greater in male than in female. Finger ridge counts are greater in fingers which shows whorl type. However, there would be other factors to determine finger ridge counts; for examples, the size and behavioral habit of finger.

1. The intracranial pressure (ICP) was raised by the extradural balloon method in urethane-anesthetized rabbits, and change of the arterial blood pressure (BP) with change of ICP was studied. 2. In the control rabbit group raising ICP resulted in marked increase in BP. 3. In the reserpine-treated group raising ICP did not induce the increase in BP but the decrease in BP. 4. In the tetrabenazine-treated group raising ICP did not cause change in BP. 5. After the administration of norepinephrine through the lateral ventricle to the reserpine-treated and tetrabenazine-treated rabbits, raising ICP resulted in marked increase in BP. 6. These results indicate that the existence of norepinephrine in the brain is essential for the BP increase by raising ICP.

BACKGROUND: This study is aimed to elucidate the developmental pattern of human fetal lip by histological and immunohistochemical examinations. METHODS: Totally 231 normal human lip tissues obtained from autopsied fetuses were fixed with 10% buffered formalin, sectioned in cross and longitudinal directions, routinely stained for H&E and performed for immunohistochemistry with antibodies of S-100 protein, proliferating cell nuclear antigen (PCNA), transglutaminase C (TGase-C), metalloproteinase (MMP)-3, MMP-10, tenascin, KL1, K8.12, E-cadherin, tissue inhibitors of matrix metalloproteinase (TIMP)-1, TIMP-2 and total keratin (TK). RESULTS: The lip structure first appeared as an orifice of stomodeum around the 7-8th week of gestation, and a major structure of the midface was observed by the 11-12th week. As the squamous epithelium of the lip became thick and was keratinized, the vermilion border became distinguished in the 15-16th week, and the lip structure was almost completed with the presence of orbicularis oris muscle in the lingual side of vermilion border by the 17-18th week. Immunohistochemically, the vermilion border showed strong reactions for tenascin, E-cadherin and MMP-3 and increased positivity for PCNA, cytokeratins (TK, KL1, K8.12), and TGase-C. CONCLUSIONS: With the above findings we suppose that the cytodifferentiation of vermilion border epithelium plays an important role for the development of human fetal lip.

BACKGROUND/AIMS: Radiofrequency ablation (RFA) is an established curative therapeutic modality for unresectable hepatocellular carcinoma (HCC), and transarterial chemoembolization (TACE) has been used as a palliative treatment for inoperable HCC. It is still unknown whether RFA and TACE are equally effective for improving the survival of patients with unresectable HCC that is amenable to either treatment. The aim of this retrospective study was to compare the clinical impacts of two treatments, and analyze the prognostic factors for recurrence and survival. METHODS: Ninety-three patients with a single HCC smaller than 4 cm who showed complete responses (complete ablation or complete lipiodol tagging) after treatment with RFA (n=43) or TACE (n=50) between January 2002 and February 2009 were investigated. Univariate and multivariate analyses were performed for 13 potential prognostic factors using the Cox proportional-hazards model. RESULTS: The time-to-recurrence rates at 1, 2, and 3 years after treatment were 32.9%, 44.3%, and 55.4%, respectively, for the RFA group, and 42%, 68.3%, 71.7% for the TACE group. The probability of survival at 1, 2, and 3 years was 97.7%, 77.4%, and 63.1%, respectively, for the RFA group, and 95.9%, 76.1%, and 60.2% for the TACE group. The time-to-recurrence and overall survival rates did not differ significantly between the two treatment groups. A multivariate Cox proportional-hazards model revealed that a tumor size larger than 3 cm and lower serum albumin levels were independent risk factors for recurrence, and that being male, being seropositive for hepatitis B surface antigen, and having a higher serum albumin level were independent favorable prognostic factors for survival. CONCLUSIONS: TACE and RFA exhibited similar therapeutic effects in terms of recurrence and survival for patients with a single HCC smaller than 4 cm, if they could exhibited complete responses.

Odontogenic gingival epithelial hamartoma (OGEH) is an extremely rare lesion characterized by an abnormal proliferation of odontogenic epithelium. This lesion is thought to arise from the rest of the dental lamina lying dormant in the gingival tissue after odontogenesis. Distinguishing OGEH from the granular cell variant of ameloblastoma and central odontogenic fibroma is important. To date, only eleven cases have been reported, and its pathogenesis remains unclear. We report here on a case of OGEH, where the epithelial strands in the lesion were conspicuously positive for the antisera of cytokeratin 19 and ameloblastin. Tumor cells intensely expressed ameloblastin mRNA by in situ hybridization. To the best of our knowledge, this is the first case of OGEH to which ameloblastin immunohistochemical stain and in situ hybridization were applied. Although our study is limited to a single case, the coexpression of cytokeratin 19 and ameloblastin might indicate the origin and specific cytodifferentiation of OGEH is quite different and unique, when contrasted to other odontogenic tumors.

OBJECTIVE: To evaluate the depiction rate and morphologic features of myocardial bridging (MB) of the left anterior descending coronary artery (LAD) using dual-source CT (DSCT). MATERIALS AND METHODS: CT scans from a total of 1,353 patients who underwent DSCT were reviewed retrospectively for LAD-MB. Seventy-eight patients were excluded due to poor image quality or poor enhancement of the coronary artery. The length and depth of the MB were analyzed and classified as superficial or deep with respect to the depth (< or = 1 or > 1 mm) of the LAD tunneled segment. Superficial MB was subdivided into complete or incomplete types according to full or partial encasement of the myocardium. RESULTS: Of the 1,275 patients included in this study, 557 cases of MB were found from 536 patients (42%). Superficial MB was observed in 368 of 557 (66%) cases, and deep MB was seen in 189 of 557 (34%) cases. Superficial MB showed 2 types: complete (128 of 368, 35%) and incomplete (240 of 368, 65%). The mean length of a tunneled segment for superficial MB was 16.4 +/- 8.6 mm. The mean length and depth of a tunneled segment for deep MB were 27.6 +/- 12.8 mm and 3.0 +/- 1.4 mm, respectively. The incidence of atherosclerotic plaques in a 2-cm-long segment proximal to MB was 16%. CONCLUSION: The depiction rate of LAD-MB using DSCT in a large series of patients was 42%, with two-thirds of MB segments being the superficial type.

OBJECTIVE: In order to elucidate the retrogressive degeneration of orofacial cleft, the fissured tissues of prenatal and postnatal cleft lip and palate were examined by histological and immunohistochemical methods. DESIGN: Totally 42 cases of prenatal (n=17) and postnatal (n=25) cleft lip and/or palate were examined in comparison with 10 cases of normal lip and oral mucosa using immunohistochemical stainings of MMP-3, MMP-9, MMP-10, cathepsin G, PCNA, E-cadherin, TGase 2, HSP-70, vWF, and VEGF. MAIN OUTCOME MEASURES: In the fissured tissue the sebaceous glands were strongly positive for PCNA and grew into the underlying fibromuscular tissue (24/42). Some hyperplastic sebaceous glands of prenatal cleft lip produced infundibular follicular cyst (9/17). The skin and mucosal epithelia from the postnatal cleft lip and palate (10/25) showed severe basal hyperplasia (11/25) and melanocyte infiltration (7/25). RESULTS: The immunostaining of MMP-3 and HSP-70 were strongly positive in the hyperplastic sebaceous glands and nearby atrophying muscle bundles of the fissured tissue, while MMP-9, MMP-10, and cathepsin G were almost negative. The immunoreactions of the other antibodies used in this study were similar between in the fissured tissues and in the normal controls. CONCLUSIONS: These data suggest that the over-expression of MMP-3 is closely related to the sebaceous gland hyperplasia, epithelial dysplasia, and the muscle degeneration, and that the over-expression of MMP-3 in the fissured tissue may continuously aggravate the cleft condition in the later life.
