Abstract
BACKGROUND Primary ovarian mucinous tumors are uncommon. Factors leading to invasive progression and metastatic disease have not been fully delineated yet. The aim of this study is to determine the rates of p53 and p16 immunoexpressions in primary ovarian mucinous tumors, to investigate their relationship with clinicopathologic factors and their impact on prognosis and survival. METHODS Seventy-eight primary ovarian mucinous tumors (30 mucinous cystadenomas, 30 mucinous borderline tumors (MBOT), 18 mucinous carcinomas (MOC)) were evaluated immunohistochemically with p53 and p16 staining. The demographic, clinicopathological data, and postoperative follow-up findings of the patients were analyzed. RESULTS Mutation-type p53 staining was present in 1/30 (3.3 %) cystadenoma, 10/30 (33.3 %) MBOT and 9/18 (50 %) MOC (p = 0.001). p16 overexpression was detected in 3/30 (10.0 %) MBOT and 5/18 (27.8 %) MOC, but not in any cystadenoma (p = 0.04). The frequency of mutation-type p53 staining in MBOTs with microinvasion was higher (71.4 %) than in those without (28.6 %, p = 0.026). The frequencies of p16 or p53 mutations were similar in MBOTs with and without intraepithelial carcinoma, microinvasion or mural nodule (p > 0.05). In MOCs with ovarian surface involvement, mutation-type p53 staining was detected in 66.7 % (6/9) and p16 overexpression in 55.6 % (5/9) of the cases. A significant difference was found between MOCs with or without ovarian surface involvement regarding the frequency of p16 overexpression (p = 0.029). Any relationship was not detected between survival and p53 and p16 expression in MOCs (p > 0.05). CONCLUSION p53 and p16 mutation rates were higher in MOCs compared to mucinous cystadenomas and MBOTs and suggest a relevant role in the development of primary ovarian mucinous carcinoma, however further studies are needed in this regard.

Abstract
PURPOSE The primary aim of this study was to determine the prevalence of HPV in pterygium with polymerase chain reaction (PCR) testing and to investigate the relationship with clinicopathological factors. A secondary aim was to evaluate the relationship between HPV and the recurrence of pterygium. METHODS The study included 60 patients. PCR analysis was used to determine the presence of HPV. All the patients were followed up in respect of the development of recurrence. Analyses were performed of patient age, pterygium site, specimen and pterygium size, histopathological findings, HPV status, operation technique and postoperative follow-up findings. In the HPV-positive patients, the relationship between HPV subtypes and other factors was evaluated. To determine the risk factors affecting recurrence rates, multivariate Cox regression analysis was applied subsequent to univariate analysis. In the Cox regression model, HPV status, age, sex, specimen size, size and site of pterygium were included among factors that may affect recurrences rates. RESULTS Of the total 60 patients, the HPV-PCR test result could not be analysed in 14 because of an insufficient sample. Of the 46 patients with sufficient material for HPV-PCR analysis, the HPV-PCR result was positive in 15 (32.6%). The HPV subtype most often determined was type 16. No statistically significant relationship was determined between HPV positivity and HPV subtype and age or sex. Recurrence was determined in 10% of all the patients. Of the cases determined with recurrence, 66.7% were HPV positive. According to Kaplan-Meier analysis, the recurrence rates in HPV-positive and HPV-negative patients were 26.7% and 6.5%, respectively. A statistically significant difference was found between two groups in terms of recurrence rates (p: 0.046). According to the results of multivariate Cox regression analysis, though not statistically significant, the risk of recurrence was increased 6.18 times in HPV-positive patients with pterygium compared to HPV-negative ones. CONCLUSION HPV infection may have a role in the development of pterygium and recurrence, but may not be sufficient alone. HPV probably has a role in the development of pterygium by acting together with several co-factors in the multi-stage process.

Abstract
PURPOSE Vagal nerve stimulation (VNS) is an effective treatment for patients with epilepsy, depression, and other neuropsychiatric conditions. Understanding the tissue changes associated with VNS devices is crucial for optimizing patient outcomes and device development. This study aimed to investigate the histopathological changes in the tissues surrounding the VNS generator and explore potential correlations with clinical factors and battery performance. METHODS A total of 23 patients who underwent VNS generator revision surgery owing to battery depletion were included. Tissue samples from the areas surrounding the VNS generator were obtained and analyzed for histopathological changes. Demographic and device-related variables were also recorded. RESULTS Capsule formation was observed in all patients. Acute inflammation were not detected in any case. Perivascular lymphocytic infiltration, foreign-body giant cell reaction (FBGCR), and calcification were observed in 8.7%, 26.1%, and 43.5% of patients, respectively. Crystalloid foreign body appearance was noted in 4 patients. The median output current of the generator was higher in patients with lymphocytic infiltration than in those without lymphocytic infiltration. The median off time was higher in patients with skin retraction than in those without skin retraction. Moreover, discomfort was associated with the presence of FBGCR. CONCLUSION Our study provides insights into the tissue changes associated with the VNS generator, with capsule formation being a common response. Crystalloid foreign body appearance was not reported previously. Further research is needed to understand the relationship between these tissue changes and VNS device performance, including the potential impact on battery life. These findings may contribute to VNS therapy optimization and device development.

Abstract
Context HER2-targeted therapy has been shown to benefit HER2-positive gastric cancer. It is very important to determine the HER2 expression level correctly to select the appropriate test and sampling method. Aim In this study, we investigated the frequency of overexpression of HER2 and intratumoral heterogeneity of HER2-positive cases, comparison of HER2 used immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) performance in biopsy and resection specimens, the correlation of HER2 status between biopsy and resection specimens, and its relationship with clinicopathological findings. Materials and Methods Formalin-fixed, paraffin-embedded specimens of a total of 40 surgically resected and biopsy specimens of gastric cancer were analyzed. HER2 status was examined using both IHC and FISH techniques, and the findings and their association with different clinicopathological parameters were evaluated. Results The concordance rate between the results of IHC and FISH in biopsy and resection specimens was 96.6% and 86.6%, respectively. In paired 20 cases, the overall concordance rate of HER2-IHC and HER2-FISH status between biopsy and resection specimens was 90% and 100%, respectively. HER2-IHC analysis revealed that 5/40 cases were IHC 2+ and only 1 of 5 IHC 2+ cases demonstrated HER2-FISH amplification. Conclusion Our results showed that HER2-IHC was well concordant with FISH in cases with a score of 0/1+ or 3+ and demonstrates strong concordance between biopsy and resection specimens. FISH should be performed when the IHC result is equivocal. In our study, no statistically significant correlation was observed between HER2 positivity and clinicopathological parameters. Overall, both biopsy and resection specimens are appropriate for HER2 testing.

Abstract
CONTEXT p16 is an important tumor suppressor gene and responsible for regulating the cell cycle. Diffuse positivity with p16 in the cervix and head/neck carcinomas can be regarded as a surrogate marker of the presence of high-risk human papillomavirus (HPV). AIM The aim of our study was to search the existence of p16 expression in pterygium. We also analyzed the association of p16 expression with epithelial dysplasia and HPV expression. SUBJECTS AND METHODS The study enrolled 75 cases of pterygium. The conjunctival tissues of 10 patients excised by the strabismus surgery were used as control group. All of the slides were stained with p16 via the immunohistochemical method. RESULTS 49 (65%) of pterygiums showed low-grade epithelial dysplasia. None of the control groups showed dysplasia. Positive expression of p16 in patient group was significantly higher (P < 0.001). Staining percentage (SP) of p16 was between 0 and 26% in pterygium; mean SP was 5.1%. There was no staining in the control group. A total of 59 (72%) pterygium cases were positive with p16. Appoximately 42 of 49 (85%) cases with dysplasia showed p16 staining. There was a significant relation between dysplasia and positive expression of p16 (P < 0.001). CONCLUSIONS P16 is significantly expressed in pterygium and correlated with epithelial dysplasia. Furthermore, the existence of p16 expression suggests that HPV is a possible ethiological factor in pterygium. We think that examination of p16 expression and analysis of HPV DNA in p16 positive cases can help us to understand the etiopathogenesis of the disease better.

Abstract
OBJECTIVES FOXA1 expression has been demonstrated in several hormone-dependent cancers. However, data are limited concerning the role of FOXA1 in endometrial cancers. The present study aimed to investigate FOXA1 expression via the microarray technique in benign hyperplasia, endometrial intraepithelial neoplasia, and endometrial endometrioid carcinoma. We also aimed to determine whether there were any associations between FOXA1 expression, tumor grade, myometrial invasion and lymphatic invasion. MATERIAL AND METHODS Paraffin-embedded sections prepared from samples obtained from 114 patients who underwent surgical hysterectomy or curettage were analyzed. Data were retrieved from digitally-stored medical records. Tissue microarrays were prepared from formalin-fixed, paraffin-embedded tissue blocks. Full tumor sections were used for immunohistochemical analysis performed. RESULTS Carcinomas with nuclear grade 3 had higher FOXA1 values than others, while grade 2 carcinomas also had higher FOXA1 values relative to grade 1 (p < 0.001). FOXA1 values of FIGO stage III carcinomas were significantly higher than others and stage II values were also significantly higher than stage I FOXA1 values (p < 0.001). Patients with myometrial and lymph node invasion had significantly higher FOXA1 values than others (p < 0.001 and p = 0.047, respectively). FOXA1 had 91.30% sensitivity, 63.60% specificity and 77.78% accuracy for predicting the presence of myometrial invasion with a cut-off value of 9. CONCLUSIONS FOXA1 expression is higher in endometrial endometrioid carcinoma compared to benign endometrial hyperplasia or intraepithelial neoplasia. In patients with endometrial endometrioid carcinoma, high FOXA1 expression is associated with high tumor grade, myometrial and lymph node invasion. However, FOXA1 expression is not associated with lymphovascular or cervical invasion.

Abstract
CONCLUSION Platelet-rich fibrin (PRF) membrane could be used successfully in the repair of tympanic membrane perforation and wound healing. OBJECTIVES To evaluate the effect of platelet-rich fibrin membrane in the repair of perforated tympanic membrane. METHODS After otoscopic examination, a 3-mm perforation was made in the posterior quadrant of both tympanic membranes of 50 adult male Sprague-Dawley rats. Venous blood was withdrawn from the rats, then centrifuged. PRF was obtained in membrane form. The membrane was placed on the right tympanic membrane perforation. The perforations on the left side were left to spontaneously heal and, thus, formed the control group. Daily examinations were made of 20 rats and the time to healing of the tympanic membrane was recorded. The remaining 30 rats were separated into five groups of six, and histopathological examination was made. Evaluation was made in respect of the presence of oedema in the lamina propria, neovascularization, fibroblastic reaction, and inflammatory cells. RESULTS The healing time of the tympanic membrane perforation was determined as mean 10.3 ± 2.18 days in the study group applied with PRF and 17 ± 2.40 days in the control group. Higher values in respect of fibrosis and neovascularization were obtained in the study group.

Abstract
BACKGROUND/AIM Many autoimmune diseases occur concomitantly with celiac disease (CD). We aimed to determine the frequency of Sjögren's syndrome (SS) in CD patients based on SS-specific serology verified by minor labial salivary biopsy. MATERIALS AND METHODS Eight-two patients with CD were included in the study. After examination for objective evidence of sicca complex, all patients were tested for serological presence of rheumatoid factor (RF) and antinuclear antibodies (ANAs) and for ANA profile. Minor labial salivary biopsy was performed for patients with positive serology and/or clinical signs of SS. RESULTS Of the patients included, 24 (29.3%) had dry eye symptoms while 20 (24.4%) had dry mouth symptoms. Dry eye was detected by Schirmer test in 10 patients (12.2%) and by ocular staining score in only 2 patients (2.4%). All samples were negative for RF while 12 (14.6%) samples were positive for ANAs. Of 82 patients with CD, the diagnosis of SS was established in only one patient (1.2%), while one patient (1.2%) was diagnosed with morphea and 4 patients (4.9%) were classified as having undifferentiated connective tissue disease. CONCLUSION The prevalence of SS in CD is low, so there is no need for serologic screening of all patients with CD for SS.

Abstract
The distinction of thyroid carcinoma from benign thyroid neoplasm, as well as the subtyping of papillary carcinoma (PC) and follicular carcinoma (FC), may be performed histopathologically in the majority of cases. However, in certain cases, it is difficult to histopathologically distinguish between PC and FC, as well as follicular adenoma (FA), FC and the dominant nodule of multinodular goiter (MNG-DN). The present study aimed to determine the roles of the expression levels of the tight junction proteins claudin 1, 4 and 7 in the differential diagnosis of PC, FC, FA, MNG-DN, medullary carcinoma (MC) and anaplastic carcinoma (AC). The current study included 114 cases of histopathologically diagnosed thyroid neoplasia, which were distributed as follows: 29 FA, 18 MNG-DN, 47 PC, 10 FC, 5 MC and 5 AC. The expression levels of claudin 1, 4 and 7 were examined using immunohistochemical methods. The results revealed a significant difference in claudin 1 expression between malignant and benign thyroid neoplasms (P<0.001). Claudin 1 expression was not detected in any of the MNG-DN cases, and no significant difference in claudin 1 expression levels was identified between FA and FC (P=0.653). However, a statistically significant difference was observed between FC and PC (P<0.001). Claudin 4 expression did not differ between malignant and benign thyroid neoplasms, neither between MNG-DN, FA and FC, nor between FC and PC (P=0.068, P=0.502 and P=0.481, respectively). Claudin 7 exhibited positive immunohistochemical staining in 107 patients (94%); however, no significant difference in claudin 7 expression §levels was identified between malignant and benign thyroid neoplasms among MNG-DN, FA and FC (malignant, P=0.135; benign, P=0.470). Claudin 7 exhibited positive staining in all PC and FC cases. Therefore, claudin 1 expression levels may be useful in distinguishing cases of FC and PC with overlapping histopathological features, and provide a novel immunohistochemical marker for the subtyping of thyroid carcinoma.

Abstract
The authors aimed to compare the maternal serum level and placental expression of resistin in pregnancies complicated by preeclampsia and clarify their relationship with disease severity. This cross-sectional study included 50 healthy pregnant women, 50 women with mild preeclampsia, and 48 women with severe preeclampsia. Serum resistin levels were measured by enzyme immunoassay and placental resistin expression was determined by immunohistochemistry. Resistin levels were significantly higher in women with mild and severe preeclampsia than in the healthy controls (p = 0.012 andp < 0.001, respectively). Placental resistin expression was significantly higher in women with severe preeclampsia compared to women with mild preeclampsia (p = 0.003) and healthy controls (p < 0.001). Serum resistin levels were positively correlated with gestational age and umbilical and uterine artery Doppler indices, as well as systolic and diastolic blood pressure, but negatively correlated with birth weight (p < 0.05). On the other hand, placental resistin expression was positively correlated with systolic blood pressure and uterine artery indices, but negatively correlated with birth weight (p < 0.05). In conclusion, increased cir- culating levels and placental expression of resistin in pregnancies complicated by preeclampsia were correlated with disease severity.

Abstract
OBJECTIVE The aim of this study was to determine the rate of Her-2 gene amplification in breast cancer cases with a previous negative Her-2 result as determined by immunohistochemistry (score 0 or 1). MATERIAL AND METHOD 552 cases of invasive breast carcinoma were assessed with the contribution of 9 centers. Previous immunohistochemistry score was either 0 or 1+ in all cases. These cases were re-tested by Her-2 silver in situ hybridization in the central laboratory. Her-2 gene amplification was defined as Her-2/CEP 17 ratio of more than 2.2. Cases with a ratio between 1.8 and 2.0 were defined as equivocal and cases with a ratio of less than 1.8 were defined as negative. RESULTS Re-testing of the 552 cases with silver in situ hybridization showed a total of 22 cases with Her-2 gene amplification, of which 11 (3.2%) were found to be score 0, and 11 were found to be score 1+ (5.3%) by immunohistochemistry previously. Her-2 gene amplification rate of cases (score 0 and 1+) ranged from 0% to 10.48% among the centers. Polysomy was found in 28 (8.1%) of the score 0 cases and 25 (12.1%) among the score 1+ cases. Five (9.4%) of the cases with polysomy were found to be amplified, and 48 (90.6%) were not. CONCLUSION The results of the study show that a group of cases (3.98%) with a potential to benefit from anti-Her-2 therapy may be missed with the immunohistochemical method. This indicates the importance of quality assurance, especially in central laboratories with many breast cancer cases in daily practice.

Abstract
OBJECTIVE Predictive factors of damage to the Fallopian tube may guide the treatment for patients with tubal pregnancy. The purpose of this study was to evaluate the predictive value of ultrasonographic findings in patients affected by ampullary pregnancy for the determination of the depth of trophoblastic infiltration into the tubal wall on histological examination. MATERIAL AND METHODS 38 patients with ampullary pregnancy undergoing salpingectomy were enrolled into the study. The patients were divided into two subgroups depending on their transvaginal sonography (TVS) findings; either an ectopic gestational sac containing an embryo with cardiac activity or those with a tubal ring. The ampullary pregnancies were histologically classified according to the depth of infiltration of trophoblastic tissue into the tubal wall as follows: stage I: limited to mucosa; stage II: extension to the muscularis layer; stage III: complete infiltration of the tubal wall with or without rupture of the serosa. The association between findings on TVS and stage of trophoblastic invasion, serum beta-human chorionic gonodatropin (β-hCG) levels was evaluated. RESULTS Although there was no significant difference among two groups in terms of histological stage of trophoblastic infiltration (p = 0.257), patients in whom an embryo with cardiac activity had been identified were found to have higher percentage of stage II (47.8%) or stage III (8.7%) invasion. However, there was a significant difference in serum β-hCG levels on the day of surgery among the two groups (p = 0.028). CONCLUSIONS Ultrasonographic aspect of ampullary pregnancy is associated with depth of trophoblastic infiltration into the tubal wall and serum β-hCG levels.

Abstract
BACKGROUND Tight junction proteins in the cell organize paracellular permeability and they play a critical role in apical cell-to-cell adhesion and epithelial polarity. Claudins are major integral membrane proteins of tight junctions, especially Claudin 1, 4, and 7, which are known as the impermeability Claudins. In this study, we investigated the importance of loss of Claudin 1, 4, and 7 expression, and their relation to tumor progression in colorectal cancer patients. MATERIAL/METHODS Loss of Claudin 1, 4, and 7 expression was examined by immunohistochemical method in 70 patients diagnosed with colorectal cancer. Cases with loss of Claudin expression in <1/3 of tumor cells were classified as mild loss, whereas cases with loss of Claudin expression ³1/3 of tumor cells were classified as moderate-to-marked loss in order to evaluate the relation between loss of Claudin 1, 4, and 7 expression and clinicopathologic data. RESULTS The severe suppression of Claudin 1, 4, and 7 expression was found to be significantly related to the depth of tumor invasion, positive regional lymph nodes, histological grade, lymphovascular invasion, perineural invasion, and lymphocytic response. Additionally, severity of loss in Claudin 4 expression was found to have a relation with distant metastasis. CONCLUSIONS Claudin 1, 4, and 7 are important building blocks of paracellular adhesion molecules. Their decreased expression in colorectal cancer seems to have critical effects on cell proliferation, motility, invasion, and immune response against the tumor.

Abstract
OBJECTIVE TTF-1 is widely used as an immunohistochemical marker of lung and thyroid tumors. However, TTF-1 expression has been described in tumors from other sites. The presence of TTF-1 expression in primary brain tumors is largely unclear and has not been clearly specified yet. We characterized expression of two TTF-1 clones in primary brain tumors with relevance to tumor types and grades. MATERIAL AND METHOD We studied immunohistochemistry with tissue micro-array, using both clones (8G7G3/1 and SPT24) in 45 primary brain tumors of different types and grades. Our cases consisted of 1 grade I, 7 grade II, 4 grade III, 20 grade IV astrocytic tumors; 9 meningiomas, 2 oligodendrogliomas, 1 schwannoma and 1 medulloblastoma. RESULTS We have found TTF-1 nuclear staining using the SPT24 clone in 4 cases (3 cases were grade IV and 1 was grade III). Focal and weak staining was seen in three cases and moderate-strong and diffuse staining was seen in one case. All the tumors were negative with clone 8G7G3/1. Clone SPT24 was more sensitive but less specific. CONCLUSION TTF-1 can also be expressed in primary brain tumors, particularly grade III to IV tumors. TTF-1 expression was a rare finding in previous studies, however strong and diffuse staining was not observed until today. We think that TTF-1 nuclear expression in high-grade astrocytic tumors cannot rule out primaries even when diffuse and strong staining. Clinical and pathological parameters should be evaluated together.

Abstract
Background HMGB1, the most important member of the high mobility group box protein family, is a nuclear protein with different functions in the cell; it has a role in cancer progression, angiogenesis, invasion, and metastasis development. We studied the expression of HMGB1 and whether it is a prognostic factor in colorectal carcinoma. Material/Methods The study included 110 cases that were histopathologically diagnosed with colorectal carcinoma from the tissue samples acquired by surgical resection and biopsy in Antalya Education and Research Hospital between 2008 and 2012. HMGB1 expression was examined via immunohistochemical method. Results HMGB1 expression was evaluated as negative in 32 (44.4%) of the patients and as positive in 40 (55.6%) patients. There was no relation between the HMGB1 expression and sex, age, tumor invasion depth, and histological type. However, a significant relation was detected between the HMGB1 expression and lymph node status, metastasis status, and stage (p:<0.001, p:<0.001, p:<0.001, respectively). Similar results were obtained for the relations between the HMGB1 and histological grade, perineural invasion, lymphovascular invasion, and lymphocytic response (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). Conclusions The results of our study demonstrate that HMGB1 overexpression has a significant role in tumor progression (especially migration of tumor cells) and tumor ability to metastasize in colorectal cancers; thus, it corroborates the idea that it might be an important prognostic factor.

Abstract
BACKGROUND Radiation-Induced Lung Injury has 2 components: radiation pneumonitis and radiation fibrosis. The pulmonary fibrosis has no known efficient treatment. The purpose of this study was to study the relationship between the oxidant/antioxidant status and pulmonary fibrosis in rats having radiation induced pulmonary fibrosis and to study the antioxidant effects of pentoxifylline, vitamin E, and vitamin C in the treatment of pulmonary fibrosis. MATERIAL AND METHODS The study rats were divided into 5 groups: Thoracic RT + vitamin E+ Pentoxifylline for group 1, Thoracic RT + vitamin C + Pentoxifylline for group 2, Thoracic RT + vitamin C + vitamin E + Pentoxifylline for group 3, and Thoracic RT + Pentoxifylline for group 4, and group 5 was the control group. RESULTS When groups are evaluated in pairs, significant differences between group 1 and 2, group 1 and 4, and group 1 and 5 were determined (p: 0.002, p: 0.002, p<0.001, respectively). No significant difference was determined between group 1 and 3 (p: 0.161). No significant difference was determined between group 2 and group 3, 4, and 5 (p: 0.105, p: 0.645, p: 0.234, respectively). There was no significant difference between group 4 and 5 (p: 0.645). CONCLUSIONS The combination of vitamin E and pentoxifylline is efficient in preventing radiation-induced lung fibrosis. The additional benefit of vitamin C, which is added to this combination to increase the antioxidant activity, cannot be shown. It would be useful to investigate the combination of vitamin E, pentoxifylline, and other non-enzymatic antioxidants.

Abstract
Epidermoid cysts (EC) represent less than 0.01% of all oral cavity cysts. Lateral epidermoid cysts in the neck are very rare. A male patient aged forty-five had a complaint of painless swelling in the neck. A well-circumscribed hypo-echoic mass with internal echoes was detected in the right submandibular regionby ultrasonography. There were round areas inside the cyst with acoustic shadowing. The tissue hardness and the internal nature of the mass were evaluated with sono-elastography. Magnetic resonance imaging showed the mass's location and tissue properties in more detail. Magnetic resonance images revealed a well-circumscribed mass--hyperintense on T2-weighted images, hypo-intense on T1-weighted images--in the right submandibular region that had displaced the submandibular gland and mylohyoid muscle. There was no contrast enhancement in the mass on the contrast-enhanced fat-suppressed T1-weighted MR images. In this case report, we present the imaging features of a rare lateral EC in the submandibular region.

Abstract
Pleomorphic adenoma is the most common benign tumor of the salivary glands. A 62-year-old female patient presented with epiphora and was suffering from breathing difficulties. With the diagnostic nasal endoscopy, a mass, originating from right inferior nasal turbinate and filling the entire nasal cavity, was seen. Originating from the inferior nasal turbinate is a very rare entity. Paranasal sinus computed tomography and magnetic resonance images revealed a mass that fills and expands the right nasal cavity. Mass was hypoechoic in B-mode ultrasonography and hypovascular in color Doppler ultrasonography, and rate of tissue stiffness was high in sonoelastography. These were helpful for the diagnosis.

Abstract
A 14-year-old female with Gaucher disease presented with hydrocephalus, corneal opacities, cirrhosis, and cardiac valvular involvement. A homozygous D409H mutation was identified. She underwent surgery for aortic and mitral valve replacement. Because of severe calcification of the aortic root, no successful valve replacement was performed. She died on the third day after the explorative cardiac surgery. Cardiac abnormalities represent a life-threatening presentation of the homozygous D409H mutation. Identification of this type is essential prior to initiating appropriate therapy with enzyme replacement and cardiac corrective surgery.

Abstract
Malignant eccrine spiradenomas are exceedingly rare tumors. They can arise from a preexisting eccrine spiradenoma or occur as a primary malignant tumor. Clinical features of these tumors may include a history of enlargement in a previously stable lesion. Tumor can be of low or high grade. Low-grade malignant eccrine spiradenoma has a better prognosis. We present a malignant eccrine spiradenoma arising from a preexisting eccrine spiradenoma, which has an infrequent localization between lateral edge of nose and medial canthus.

Abstract
It is uncertain whether tumors arising in transplant patients resemble ones that develop de novo in pathogenesis, morphology, and behavior. This study sought to investigate some clinical, morphological, and immunohistochemical features of several posttransplantation malignancies compared with similar de novo tumors. The study group consisted of 40 malignant tumors encountered in 1350 transplant patients (1229 kidneys, 113 livers, 8 hearts) between 1986 and 2006. Tumors with 3 or more examples were compared with randomly selected controls. These included Kaposi's sarcoma (n=14); extranodal lymphoma (n=9); squamous cell carcinoma (n=6); and nodal lymphoma (n=3). The variables that were analyzed were the localization, predisposing lesions, degree of differentiation, and host response. For lymphomas, we also determined histological subtype, origin, and Ki-67 proliferation index. Most tumors (36/40, 90%) occurred in patients with renal transplants. However, the relative frequency was higher among liver transplant cases (3.53% vs 2.92% for kidney transplants). No malignancy was seen in heart transplant cases. Squamous cell carcinomas were better differentiated (P<.05) compared with controls and they were more frequently associated with precursor lesions (P<.05). Kaposi's sarcomas involved internal organs more frequently in posttransplant patients, and the Ki-67 proliferation index was higher in posttransplantation nodal lymphomas. However, these factors were not significantly different (P>.05). Our findings suggested that certain posttransplantation malignancies display unique characteristics compared with their de novo counterparts.
