Abstract
OBJECTIVE To evaluate the quantity of tumor-associated macrophages (TAMs) in cases of Hodgkin Lymphoma of classical type (cHL), and to reveal possible associations between TAM intensity and latent Epstein-Barr virus (EBV) infection, overall survival, progression-free survival, prognostic indices, and clinicopathological parameters. MATERIALS AND METHODS A total 46 cases of cHL with complete clinical records were selected and re-evaluated histopathologically. Staining for CD68 (PG-M1; KP1 clones) and CD163 was evaluated and the cut-off values were defined. Also, all cases were evaluated using the chromogen in situ hybridization (CISH) method with EBER (Epstein-Barr virus-encoded RNA) probes for the presence of possible EBV infection. RESULTS It was found that high expression levels of PG-M1 and high International Prognostic Scores (IPS) were associated with shortened overall survival (p=0.047, p=0.013). Cases with 2 or less areas of nodal region involvement were observed to have longer progression-free survival period (p=0.043). Higher expression levels of CD68 PG-M1, CD68 KP1, and CD163 were found to show significant associations with the presence of some clinical parameters such as the presence of B symptoms, spleen involvement, and the presence of EBV infection. CONCLUSIONS Our findings suggest that increase of PG-M1+ TAM is associated with shortened overall survival, while higher expressions of all immunohistochemical markers are statistically significantly associated with the presence of EBV infection and clinical parameters mentioned above. These findings indicate that highlighting the TAM rate via macrophage markers in cases of cHL could be helpful in determining the prognostic risk groups and the relevant results should be mentioned in pathology reports.

Abstract
Xanthogranulomatous pyelonephritis (XGP) is characterized by destruction of the renal parenchyma and granulomatous inflammation with lipid-laden foamy macrophages as well as inflammatory infiltration and intensive renal fibrosis. It generally occurs in adults, especially those in the fifth and sixth decades of life, but is occasionally seen in children as well. Brachydactyly mental retardation (BDMR) syndrome (OMIM 600430) is caused by a small deletion of chromosome 2q37 and is a rare condition, with roughly 100 cases reported worldwide. Here, we describe the case of a patient with deletion of chromosome 2q37, which is known as the BDMR syndrome, and XGP.

Abstract
Squamous cell carcinoma (SCC) of the penis has been subject to only a few studies in populations where late childhood circumcision is performed. To asses clinicopathological features and human papillomavirus (HPV) status of penile SCC in men with late circumcision, eight institutions in the country volunteered to collaborate and 15 cases of penile SCC were collected from their pathology archives. The presence and genotype of HPV were determined in addition to clinicopathological features of the tumors. Findings were correlated with disease outcome. The mean age of the patients evaluated was 66.5 years. Histological subtypes were usual SCC (6∕15), papillary (2∕15), mixed (2∕15), basaloid (2∕15), acantholytic (1∕15), pseudohyperplastic (1∕15), and warty-basaloid (1∕15) carcinomas. HPV was identified in 33.3% of samples; HPV16 was detected in 60% of positive cases and was associated with basaloid and/or warty morphology. Cause-specific 1-year and 2-year survivals were 76.9% and 54.5%, respectively. The usual subtype and nodal metastasis were associated with worse outcome (p=0.045 and p=0.047, respectively). As a conclusion, our results suggest an inclination for penile SCC to develop at a later age in a population with late circumcision than the patients from the regions of high penile cancer incidence. These men seem to have less frequent HPV association and their outcome appears poorer than other populations, although reaching substantial provision is not possible due to our limited case number.

Abstract
Background An inverted papilloma (IP) is a benign sinonasal tumor of ectodermal origin, which is locally aggressive and destructive, tends to recur if incompletely removed, and has significant malignant potential. On CT scan, the appearance of an IP is variable and nonspecific but most commonly it appears to have soft tissue density. The association of IPs and new bone formation is extremely rare; to the best of our knowledge, only one case has been reported in the literature to date. Methods We report three cases with existence of bony mass surrounded by polypoid soft tissue diagnosed as IP histopathologically. Results The nature, shape, and location of the bony mass were not in concordance with trapped bone, with tumoral calcifications, or with osteoma. Conclusion We propose that with regard to the three cases presented here, new bone formation may be associated with IP pathologically. We also believe that additional investigations are required to characterize the pathophysiological mechanisms involved in neoplasm-induced osteogenesis.

Abstract
Aims and Background We aimed to investigate the factors affecting the interval from the beginning of the symptoms until diagnosis and treatment in patients with lung cancer. Methods Records of 119 lung cancer patients diagnosed in our pulmonary diseases clinic between 2004 and 2006 were evaluated retrospectively. Demographic data, histopathological tumor type, TNM stage, ECOG performance status, presence of endobronchial lesions, and radiological localization of the tumor were determined. Intervals from the first symptom to contacting a doctor, to diagnosis and to treatment were calculated. The interval from first admission to a clinic and referral to a chest physician was also calculated. Results Of 119 patients, 74% were diagnosed as non-small cell and 26% were as small cell lung cancer. Forty-eight percent of the patients were at stage 3B and 36% were at stage 4. ECOG performance status was 0 in 6%, 1 in 52%, 2 in 36%, 3 in 3%, and 4 in 2%. Endobronchial lesions were observed in 50% of the patients, and the lesions had a central radiological localization in 59%. Fifty-four percent of the patients presented to a chest physician first. Patients who first presented to an internal medicine clinic were referred to our pulmonary disease clinic significantly later than those who presented to other clinics (P = 0.005). The median period from the beginning of the symptoms until contacting a doctor was 35 days (range, 1-387), until diagnosis was 49 days (range, 12-396), and until beginning the treatment was 57 (range, 9-397) days. The presence of endobronchial lesions, radiological localization, TNM stage and ECOG performance status were not found to be related to the intervals from the first symptom to presentation to a doctor, to diagnosis or to the beginning of the treatment. Conclusions Lung cancer patients consult a doctor after a relatively long symptomatic period. Patient delays may be shortened by increasing the awareness of patients about lung cancer symptoms. Diagnostic procedures should be performed more rapidly to shorten doctor delays.

Abstract
Introduction: Vena cava thrombus is an extremely rare complication of testicular tumors. We report on an unusual case of testicular tumor presenting with inferior vena cava thrombus extending from the left spermatic and bilateral external iliac veins to the hepatic vein. Case report: A-35-year old man presented with a 6-month history of left scrotal mass and a 1-day history of bilateral lower extremity edema. Computed tomography (CT) revealed the presence of thrombus extending from the left spermatic vein and bilateral external iliac veins to the hepatic vein, and multiple lymph node and lung metastases. 3 cycles of chemotherapy were given after the left high inguinal orchiectomy. Pathological examination demonstrated a pure yolk sac carcinoma with lymphovascular invasion and direct tumor extension into the left spermatic cord. CT and positron emission tompgraphy-CT obtained no findings of metastasis or recurrence at 3 months after the chemotherapy. Conclusion: We review this seldom case and discuss the literature with regard to its diagnosis and treatment.

Abstract
Objectives: To compare pathological samples obtained from cases that underwent surgery for ureteropelvic junction (UPJ) obstruction with samples obtained during autopsies of subjects. Methods: Retrospectively, 42 patients who had undergone surgery due to UPJ obstruction (group 1) were included in the study. Histopathological and immunohistochemical features for sonic hedgehog (SHH), TBX18, and TSHZ3 of UPJ were evaluated and findings were compared with 20 autopsy cases (group 2). Results: In group 1, the scores were statistically significantly higher in terms of cytoplasmic SHH, nuclear TBX18, cytoplasmic and nuclear TSHZ3 staining. Statistically, no correlation was found between age and the staining scores belonging to these 3 antibodies in group 1 and group 2. Intense inflammation was found to be related with nuclear staining for TBX18. Conclusion: Gene product expressions of SHH, TBX18 and TSHZ3 are statistically higher in patients with UPJ obstruction, when compared with control group. The explanation may be the reactivation of the processes, which had shown their effects in the embryological period, due to the chronic inflammation and long-term micro-trauma created by the disease.

Abstract
BACKGROUND We studied cyclooxygenase-2 (COX-2) immunohistochemical staining intensity both in prostatic biopsy and surgical samples of patients with prostate cancer to determine if it might provide prognostic information for the decision of re-biopsy indication. METHODS Twenty-eight patients undergone radical prostatectomy whose final pathologic examination revealed prostatic adenocarcinoma were included in the study. Twelve patients with BPH in their pathological examination of both prostatic biopsy and open prostatectomy were considered as a control group. Intensity of COX-2 receptor was examined with immunohistochemical staining according to standard techniques. RESULTS Positive COX-2 receptor staining was obtained 89.3% of biopsy samples and 93% of surgical samples in all cancer patients. The rate of agreement in COX-2 receptor staining of biopsy samples and radical prostatectomy samples was 76% in same patients (P=0.54). Similarly, the COX-2 receptor levels in biopsy specimens of patients with BPH open surgery compared with samples of the agreement still rate was 41% (P=0.41). Prostate cancer exchanging COX-2 receptor levels in patients with biopsy specimens in patients with BPH were found significantly more (P=0.008). CONCLUSIONS In this study the feasibility of presence of COX-2 receptor staining in biopsy samples was shown. We have also demonstrated that COX-2 staining intensity was higher in prostatic biopsy samples of patients with prostatic cancer than patients with BPH. This leads a conclusion that, higher COX-2 expression levels in biopsy specimens may be used to decide re-biopsy in borderline preoperative PSA levels as well as in the cases with suspicious pathological findings for cancer.

Abstract
Synchronous bilateral testicular germ cell tumors (TGCTs) are seen in exteremely rare cases. Although there is still no standard therapy for bilateral TGCTs, bilateral orchiectomy is recommended as the gold standard treatment. Nevertheless, it has some long-term problems, such as infertility and psychosocial difficulties, and thus some clinicians prefer to perform testis-sparing surgery in appropriate cases. We reviewed the first case of bilateral synchronous TGCT with concomittant bilateral diffuse intratubular germ cell neoplasia in a young single patient, who was treated by a left radical orchiectomy and right testis sparing-surgery with following local radiotherapy to the right residual testicular tissue with previous semen cryopreservation to maintain the ability to father children. We supposed that testis-sparing surgery can be a feasible therapeutic alternative to radical orchiectomy in patients with bilateral TGCTs in terms of improving the quality of life and continuing fertility and normal hormonal status with no medications. However, while the long-term effects are not yet known, this type of treatment should be perpormed in carefully selected cases with longlife expectancy.

Abstract
The diagnosis of synchronous prostatic and rectal carcinomas is uncommon. To make a correct diagnosis, biopsies of both sites are mandatory. Pathological slides should be compared and immunohistochemical staining should be taken into consideration. In this paper, an unexpected case of synchronous rectal and prostatic carcinomas arising in an 84-year-old male with hematemesis and pelvic pain is reported. These two tumoral components have a distinctive histological appearance. Immunohistochemical evaluation confirmed the diagnosis of these synchronous tumors. This case emphasizes that rectal and prostatic carcinomas can arise simultaneously. In this situation, providing clinicopathological correlation and deciding the necessity of intraoperative consultation in proper time are extremely important.

Abstract
BACKGROUND Urachal carcinomas are rare tumors, and the majority of them are adenocarcinomas. Up to now, only 21 urachal urothelial carcinomas (UCas) have been reported. Here, we describe a case of high grade UCa arising from the urachal remnants. CASE A 66-year-old man presented with voiding difficulties. Prostate specific antigen (PSA) was 5.46 ng/mL. Prostatic adenocarcinoma (PCa) (Gleason score 6) was diagnosed by needle biopsies. After the diagnosis of high grade, muscle invasive UCa with intact mucosa on frozen examination of the dome of bladder wall during the radical prostatectomy operation (RPO), partial cystectomy was performed. Microscopically, among the tumoral islands, cystic structures lined by cells with a benign appearance, which are considered urachal remnants, were noted. Cytokeratin 7 and high-molecular-weight cytokeratin were strongly positive, PSA and carcinoembryonic antigen were negative. Radiotherapy was given for both UCa and PCa. Six months after the diagnosis, an undifferentiated tumor was detected in a bladder transurethral resection specimen; thus, chemotherapy was given. After 1 course of chemotherapy, the patient was doing well. CONCLUSION The origin of urachal carcinomas is usually obscured as it is a highly invasive carcinoma. The patient presented here was diagnosed incidentally during RPO. Although the stage was advanced, the tumor was detected before urachal remnants were destroyed. The treatment choice for urachal carcinomas is cystectomy. Adjuvant chemotherapy and radiotherapy are controversial.

Abstract
Targeted therapy in the management of metastatic renal cell cancer has been recently introduced to urology practice. The drugs used for management are used in a very limited number of patients and only for clear cell histology. We present a case where we administered sorafenib, a multikinase inhibitor of tumor-cell proliferation and angiogenesis, to a patient with metastatic renal cell carcinoma of clear cell histology. We found that our results were different from those of previously reported studies, because sarcomatoid differentiation was evident in a histological examination of this case. There was an excellent response to sorafenib. This case report might provide evidence that antiangiogenic agents may be active in any histological type of renal cell carcinoma. However, there are no available data to demonstrate the duration of response and survival benefit.

Abstract
OBJECTIVE To investigate the diversity within invasive ductal carcinoma (IDC) and prostatic adenocarcinoma (PCa) by evaluating immunohistochemical expression of heat shock protein 47 (HSP47) and fascin, the molecules that are related to desmoplasia and invasion, and analyze its correlation with clinicopathologic parameters. STUDY DESIGN HSP47 and fascin immunoreactivity (IR) was evaluated in 49 mastectomies diagnosed as IDC and 57 radical prostatectomies diagnosed as PCa. IR was evaluated as: 0: < 5%, 1+: 5-25%, 2+: 25-50%, 3+: > 50%. RESULTS HSP47 and fascin were localized to cytoplasm, and HSP47 and fascin IR were higher in IDC and PCa than benign groups (p < 0.05). HSP47 IR in neoplastic cells was 42.1% and 28.6%, in stroma was 81.6% and 15.8% in IDC and PCa, respectively; fascin IR in neoplastic cells was 65.3% in IDC and 15.8% in PCa. Fascin expression correlated with estrogen receptor and progesterone receptor negativity, tumor size and stage in IDC and surgical margin status in PCa. HSP47 expression correlated bilaterality in PCa. HSP47 positively correlated with survival in IDC. CONCLUSION HSP47 and fascin expression may play role in the pathogenesis of IDC and PCa because their expression is significantly higher in IDC and PCa than their normal counterpart. Although there is no relationship with recurrence or metastatic status, fascin overexpression correlated with tumor size, which may prompt its use as a prognostic factor in IDC.

Abstract
BACKGROUND/AIMS This study is aimed to investigate abnormal expression of the Rb protein (pRb), p16(INK4a) (p16) and cyclin D1 in colorectal adenomas and adenocarcinomas and to assess the possible alterations in Rb pathway in colorectal carcinogenesis. METHODOLOGY 44 cases of colorectal adenoma and 44 cases of colorectal adenocarcinoma were examined histopathologically and immunohistochemically using monoclonal antibodies to identify abnormalities of pRb, p16, and cyclin D1 expression. Staining degree of above-mentioned markers was assessed by using a semi-quantitative method in all cases in order to determine any staining differences. RESULTS In 70.5% of the adenomas and 97.7% of the adenocarcinomas, an overexpression of pRb was found. There was a statistically significant relationship between the immunoreactivity of pRb and villous/tubulovillous types of adenomas (p < 0.05). There was a loss of p16 expression in 84.1% of adenomas and 61.4% of adenocarcinomas. Statistically significantly, the p16 overexpression was not seen in any of tubular adenomas (p < 0.001). Overexpression of cyclin D1 was found in only 9.1% of adenomas, while 31.8% of adenocarcinomas overexpressed this protein. Loss of expression of cyclin D1 was similar in adenomas and adenocarcinomas (27.3% and 25%, respectively). Staining degrees of all three cell cycle proteins were shown to be statistically different in adenomas and adenocarcinomas, for pRb (p = 0.001), for p16 ( p = 0.045), and cyclin D1 ( p = 0.05). Also, there was only a mild agreement with respect to p16 and cyclin D1 relationship between for adenomas ( K = +0.28 p = 0.051) and for adenocarcinomas ( K = +0.35 p = 0.017). Besides, there was no correlation between the expression of pRb, p16, and cyclin D1 and clinicopathological tumor characteristics and prognostic data such as stage or lymph node/liver metastasis. CONCLUSIONS pRb, p16 and cyclin D1 are shown to be aberrantly expressed in both colorectal adenomas and adenocarcinomas. It can be claimed that disturbances in Rb pathway take part in colonic carcinogenesis and pRb, p16 and cyclin D1 play an ever increasing role in the further stages of adenoma-carcinoma sequence.

Abstract
Carcinoma in situ (CIS) of the urinary bladder is defined as a flat lesion comprising of cytologically malignant cells which may involve either full or partial thickness of the urothelium. De novo CIS constitutes less than 3% of all urothelial neoplasms; however, CIS detected concurrently or secondarily during follow-up of urothelial carcinoma constitutes 45% and 90%, respectively, of bladder cancer. CIS is noted predominantly in male smokers in the sixth or seventh decade. Patients may present with dysuria, nocturia, and urinary frequency and urgency with microscopic hematuria. Cystoscopic findings may range from unremarkable to erythema or edema. Urine cytology is an important diagnostic tool. Cellular anaplasia, loss of polarity, discohesion, nuclear enlargement, hyperchromasia, pleomorphism, and atypical mitoses are the histopathologic hallmarks of CIS. Extensive denudation of the urothelium, monomorphic appearance of the neoplastic cells, inflammatory atypia, radiation induced nuclear smudging, multinucleation, and pagetoid spread of CIS may cause diagnostic difficulties. Together with clinical and morphologic correlation, immunostaining with CK 20, p53 (full thickness), and CD44 (absence of staining) may help accurately diagnose CIS. Fluorescent in situ hybridization analysis of voided urine for amplification of chromosomes 3, 7, and 17 and deletion of 9p has high sensitivity and specificity for diagnosing CIS in surveillance cases. Several other molecular markers, such as NMP 22 and BTA, are under evaluation or used variably in clinical pathology. Intravesical bacillus Calmette-Guerin (BCG) instillation is considered the preferred treatment, with radical cystectomy being offered to refractory cases. Chemotherapy, alpha-interferon, and photodynamic therapy are other modalities that can be considered in BCG-refractory cases. Multifocality, involvement of prostatic urethra, and response to BCG remain the most important prognostic factors, although newer molecular markers are being evaluated for this entity. Patient outcome varies based on whether it is de novo development or diagnosed secondary to prior or concomitant papillary bladder cancer. From a clinical perspective, the principal determinants of outcome are extent of disease, involvement of prostatic urethra, response to therapy, and time to recurrence.

Abstract
Background Mucormycosis is an uncommon, rapidly progressive, commonly fatal, opportunistic, fungal paranasal sinus infection. The most critical decision in the management of rhino-orbital mucormycosis is whether the orbit should be exenterated. The literature fails to provide a broad base of information of how physicians determine the need for exenteration in daily practice. The decision for exenteration often depends on the judgment of the treating otolaryngologist. The authors report their experience and outline that orbital exenteration may not be mandatory in all cases of rhino-orbital mucormycosis. Methods The medical records from Celal Bayar University Medical Faculty Department of Otorhinolaryngology/Head and Neck Surgery were retrospectively searched from 1995 to 2007 for three cases with rhino-orbital mucormycosis, treated without orbital exenteration. Results All patients with rhino-orbital mucormycosis who were treated without exenteration survived. Conclusion The favorable outcome was attributable to rapid correction of the underlying medical condition; wide local excision and debridement of all involved and devitalized sinonasal and periorbital tissue, while establishing adequate sinus and orbital drainage; daily endoscopic assessment with multiple sinus debridement when necessary; daily irrigation of the involved areas; and high-dose i.v. amphotericin B.

Abstract
This research was conducted to evaluate the effects of a transverse vs. longitudinal incision for testicular sperm retrieval. Rats were divided into 4 groups: I: control, II: sham operation, III: longitudinal incision TSRM, IV: transverse incision TSRM. Group II (sham operation) had a dissection of left testis/spermatic cord, then closure of wound. Group III underwent dissection of left testis, then a "longitudinal" incision (15 mm long) of testis, which was fully opened then closed again and sutured with 5-0 Vicryl sutures. Group IV underwent dissection of the left testis, opening of the testis with a "transverse" incision, then closure with 5-0 Vicryl. The seminiferous tubule diameter was 0.118-0.224 mm in all groups. Inflammation and abscess formation occurred in one testis each in the sham and longitudinal incision groups, and in two testes in the transverse incision group. There were no differences in histopathology or scoring between the longitudinal and the transverse incision.

Abstract
Neuroblastoma is an undifferentiated malignant tumor of the primitive neuroblasts. Orbital neuroblastoma is typically a metastatic tumor. We describe a two-days-old girl, who presented with a large tumor in her left orbit. Magnetic resonance imaging revealed that the tumor originated from the retrobulbar area, extending into the upper and lateral orbit. She was operated on the fifth day of life. A histopathologic diagnosis of neuroblastoma was made. Medical evaluation including chest roentgenogram, ultrasonography of the abdomen, whole body computerized tomogram and bone scintigraphy showed no evidence of systemic involvement or metastasis. Neuroblastoma should be considered in the differential diagnosis of neonatal orbital tumors.

Abstract
BACKGROUND Keratinocyte damage and lichenoid-interface reaction are the two major pathologic findings in lichen planus (LP). Matrix metalloproteinases (MMPs) are proteinases that participate in extracellular matrix (ECM) degradation and may play an important role in basal membrane (BM) damage in LP. Fibronectin (FN) mediates a variety of cellular interactions with ECM and plays important roles in cell adhesion, migration, growth and differentiation. OBJECTIVE To determine MMP-2, MMP-3, MMP-9 and FN expressions in LP and discuss the possible associations. MATERIALS AND METHODS Skin biopsy samples of 55 patients with LP and 11 normal skin were investigated. Five discoid lupus erythematosus (DLE) and 5 chronic dermatitis (CD) samples were also examined for comparison. Immunochemical stainings were performed for MMP-2, MMP-3, MMP-9 and fibronectin. RESULTS Weak or absent expressions of MMP-2 and MMP-3 in epidermis; and dense MMP-9 expression in dermal inflammatory infiltrate cells were detected in LP. FN expression was lost in epidermal basal layer and papillary dermis. CONCLUSION Loss of MMP-2, MMP-3 and FN in LP can be explained with the destruction of the epidermal basal layer. Similar expressions of MMP-2 and MMP-3 both in LP and DLE implied that these MMPs may be involved in the pathogenesis of interface dermatitis.

Abstract
Myelofibrosis is a rare disorder in childhood. In this report, we present the case of a 6-month-old infant with myelofibrosis due to severe vitamin D deficiency rickets. The characteristic clinical and laboratory findings of myelofibrosis improved rapidly after vitamin D therapy. In developing countries, nutritional rickets is still an important health problem. Rickets is not only a skeletal system-related disorder, it is also a systemic disorder. Rickets should be considered, therefore, as one of the conditions that can lead to severe haematological disorders in infants.

Abstract
BACKGROUND/AIMS Endometrial polyps are quite common in the general population, they have a significant role in postmenopausal bleeding, and the pathogenesis is unclear. The aim of this study was to investigate proliferation markers and expression of estrogen and progesterone receptors in endometrial polyps in postmenopausal women. METHODS Endometrial polyps were removed by hysteroscopy from 36 women who presented with postmenopausal bleeding. None were using hormonal therapy. The control group consisted of 16 inactive-atrophic postmenopausal endometrial specimens removed at hysterectomy. Immunohistochemistry was used to demonstrate expression of estrogen and progesterone receptors and the cell growth and apoptosis markers, Ki67, bcl-2, c-erbB-2. RESULTS In both the glandular epithelium and stroma of endometrial polyps, estrogen and progesterone receptors, Ki67 and bcl-2 showed significantly more positive staining than the inactive endometrium from the control group. There was no difference in expression of c-erbB-2 between the two groups. CONCLUSIONS Estrogen may have a role in the development of postmenopausal endometrial polyps, either by direct stimulation of localized proliferation or by stimulation of proliferation via other pathways, such as activation of Ki67 or through inhibition of apoptosis via bcl-2. c- erbB-2 is unlikely to play any role in development of these lesions.
