Abstract
OBJECTIVES The aim of this study was to evaluate heat shock protein 90 (HSP90) expression in squamous lesions (SLs) and to assess its diagnostic value for different lesions within the SL spectrum. METHODS A total of 70 conjunctival SLs, including 19 papillomas, 22 cases of conjunctival intraepithelial neoplasia (ConINs) I, 11 cases of ConIN II, six cases of ConIN III, and 12 squamous carcinomas (sqCAs), were evaluated using the German immunoreactive score against HSP90. RESULTS Cytoplasmic HSP90 expression differed between low- and high-grade lesions (P < .001). Among high-grade lesions, the nuclear HSP90 score was higher in the ConIN III-sqCA group than in the ConIN II group (P = .0162). A percentage of total thickness staining of less than 73% differentiated between ConIN III and sqCA. CONCLUSIONS The expression of HSP90 is particularly useful to differentiate low-grade from high-grade lesions of the conjunctiva. HSP90 may play an important role in the malignant transformation of SLs and could be a new target for therapy.

Abstract
Low-grade epithelial proliferations of the sinonasal tract include Schneiderian papillomas, respiratory epithelial adenomatoid hamartoma, seromucinous hamartoma and low-grade non-intestinal adenocarcinoma. There is considerable overlap in their clinical presentation, endoscopic appearance, and imaging features. Although well-described diagnostic criteria exist, a definitive diagnosis may be difficult to reach on a small biopsy. Schneiderian papillomas are divided into fungiform, inverted, and oncocytic types, each with characteristic clinical and morphological features. The latter two may progress to malignancy. The majority are still considered to be HPV-related. Two lesions are designated as hamartomas, but their pathogenesis remains uncertain, with inflammatory and neoplastic origins proposed. Respiratory epithelial adenomatoid hamartoma is increasingly being recognized for its association with chronic rhinosinusitis and olfactory cleft site of origin. Seromucinous hamartoma has gained attention in recent years and overlaps with both respiratory epithelial adenomatoid hamartoma and low-grade non-intestinal adenocarcinoma. Controversy surrounds their distinction, particularly from low-grade adenocarcinoma. The latter generally is cured by complete excision, with a 26 % risk of recurrence but rare metastases and deaths from disease.

Abstract
PURPOSE Laryngeal papillomatosis can be an aggressive and potentially life-threatening disease, affecting both children and adults. Local excision is the gold standard of treatment, but recurrences are frequently inevitable. The purpose of this study was to present the experience of three institutions with different therapeutic modalities and discuss them in relation with the relevant literature. METHODS Sixty patients underwent papilloma resection during the last decade in three institutions (Homburg/Saar and Marburg, Germany and Athens,Greece). Patient data were retrospectively analyzed for therapeutic modalities applied, rate of complications and synechia formation, necessary operations and need for tracheostomy. RESULTS Carbon dioxide laser therapy was the most common modality applied alone or combined with other treatment modalities. No major complication was observed, while glottic synechia was the most common minor complication in 5 (8.3%) patients. Of the patient cohort 55.6% required reoperation, while no patient required tracheostomy. CONCLUSIONS Surgical debulking with or without adjuvant treatment remains the mainstay of treatment, which mainly aims to reduce the number and frequency of recurrences since no definitive curative therapy is known so far.

Abstract
AIM Management of papillary breast lesions is a controversial issue, as complete excision implies surgery of numerous benign lesions. The purpose of this study was to assess concordance between percutaneous and surgical biopsy of papillomas along with factors predictive of malignancy. PATIENTS AND METHODS The study consisted of a retrospective review of papilloma cases between 2009 and 2013 at three breast cancer centers. All cases of papilloma histologically diagnosed by percutaneous biopsy and confirmed by surgical specimen were included. The biopsy results were compared with final surgical pathology. Lesion size and clinical and radiological features were recorded. RESULTS A total of 259 cases were included (188 simple and 71 complex papillomas). Concordance between histology after percutaneous and surgical biopsy was lower for complex papillomas, regardless of type, than for simple papillomas (p<0.001). The risk of having a complex papilloma was shown to be significantly higher in postmenopausal patients (p=0.023), and was 20 times higher if the percutaneous biopsy was malignant as opposed to benign (p<2.10). However, the false-negatives for percutaneous biopsy in complex papilloma cases were mainly related to atypical and in situ lesions. CONCLUSION Percutaneous biopsy does not appear adequate for identifying papillomas requiring surgical excision due to the risk of underestimation of cancerous lesions. However, certain factors predictive of malignancy may assist with surgical management, such as age and menopausal status, lesions peripheral to the nipple, and atypia on percutaneous biopsy.

Abstract
OBJECTIVE To investigate the efficacy of submucosal resection by CO2 laser in the treatment of recurrent laryngeal papilloma and the effect on prognosis. METHOD A total of 11 patients diagnosed as recurrent laryngeal papilloma were included in this review. Papilloma was marked before operation and checked under fibro-laryngoscope. Papilloma was resected completely including the submucosal tissure with CO2 laser or microequipment. In widespread papilloma, false membrane in raw surface were cleared 7-10 days after operation. Surgical specimens (including membrane) were detected by routine pathology, HPV typing and immunohistochemical pathologic examination. The patients were checked once a month in the first 3 months after operation, and then once for every 3 months. Once the hoarseness and other symptoms aggravated or the disease was recurrent, the patients were treated immediately. RESULT HPV viral DNA was found in 10/11 cases, with HPV11 (7/11 cases) and HPV6 (3/11 cases). Cases with regards to follow-up, from 6 months to 1 year, 3 cases were followed up 1 year after operation, without recurrence. Five patients including 2 children were followed up 6 to 12 months after operation, without recurrence. Two children underwent 2 or 3 operations, were followed-up more than 6 months withouting recurrence. CONCLUSION Papilloma submucosal resection could decrease postoperative recurrence and is worth to be further investigated.

Abstract
Laryngeal papillomatosis is the most common benign neoplasm of the larynx. Juvenile onset laryngeal papillomatosis tends to recur. In patients with adult onset laryngeal papillomatosis, laryngeal cancer rarely develops. This paper reports a clinical analysis of 60 patients with laryngeal papillomatosis who were treated at our clinic between January 1971 and September 2009. We analyzed the sex ratio, age at the onset of papilloma, type of developing papilloma (single or multiple type), site of developing papilloma, recurrence rate, and therapeutic modalities. Furthermore, the clinical characteristics of the patients with malignant transformation were examined. The patients were classified according to their age at the onset of the papilloma and the type of developing papilloma. The patients were grouped into a juvenile-onset group and an adult-onset group according to their age at the onset of the papilloma. They were also classified into single-type or multiple-type according to whether the initial papilloma appeared singly or multiply. The male to female sex ratios were 1.2 in the juvenile-onset group and 5.1 in the adult-onset group. Among the patients who developed papilloma at an age of under 10 years old, most of the juvenile cases had experienced onset by 4 years of age. Furthermore, the frequency of multiple-type papilloma was significantly higher in the juvenile-onset group, compared with the adult-onset group. The vocal fold was the most frequent site of the papilloma. The recurrence rate in the juvenile-onset group was significantly higher than that of the adult-onset group. A stratified analysis according to the type of papilloma occurrence, however, showed no significant difference in recurrences between the juvenile-onset and adult-onset groups. A stratified analysis according to the age at the onset of papilloma showed that the recurrence rate of multiple-type papilloma was significantly higher than that of single-type papilloma in the adult-onset group. Among multiple therapeutic modalities, vaporization by carbon dioxide laser was the most frequently used. Adjuvant therapy was performed in 6 cases who suffered from multiple relapses. The injection of interferon was performed in 5 cases, and the local injection of cidofovir was performed in 1 case. Malignant transformation of the papilloma was confirmed in 3 cases. The periods between the onset of papilloma and the malignant transformation were 40 years, 14 years, and 3 years. The present study indicates that patients with laryngeal papilloma developing at multiple sites have a significantly higher rate of relapse, even in the adult-onset group. There was no tendency in the period observed between the onset of papilloma and malignant transformation. From the standpoint of recurrence and malignant transformation, patients with papillomatosis should be carefully followed up for a long period of time.

Abstract
We report a case of a 44-year-old man who presented with a left medial canthal mass and epiphora. Imaging was suggestive of a mass continuous with the nasolacrimal sac. Subsequent surgical exploration revealed a mass adherent to bone with invasion of the lacrimal system. Histological examination revealed a squamous/transitional cell papilloma overlying a low-grade mucoepidermoid carcinoma (MEC). Complete surgical resection was completed and pathology confirmed the diagnosis. This is the first case in which a MEC has been reported concurrently with an overlying papilloma, providing support for the hypothesis that MECs arise from papillomas in the lacrimal sac. Additionally, the tissue stained positive for p63, which is congruent with MEC immunoreactivity in the salivary gland. The description of these unique histopathological findings may assist in definitive diagnosis and improve our understanding of the pathophysiology underlying lacrimal sac MEC tumors.

Abstract
BACKGROUND Confluent and reticulate papillomatosis of Gougerot and Carteaud (CRP) is a rare dermatological condition, which has not been reported widely in Asian populations. AIM To characterize the clinicopathological and diagnostic features of CRP in a South-East Asian population. METHODS The medical records of 29 patients accorded the diagnosis of CRP at the National Skin Centre, Singapore, from 1990 to 2011, were analyzed. RESULTS The male to female ratio was 2.6:1. Eight patients were Indians. The mean age at the onset of skin eruptions was 29.1 years (range 16-55 years), while the mean duration was 19.9 months (range 0.5-120 months). CRP itself was the most common preliminary diagnosis. Fungal smears were negative in all 22 instances. All 29 patients had received a trial of antifungal therapy before being seen at our center. Antifungal therapy was repeated in three subjects, and the response was uniformly poor. Conversely, the treatment response with tetracyclines was excellent, yielding more than a 50% response in all 14 patients. Four patients suffered recurrence of CRP. According to the diagnostic criteria set forth by Davis et al., 25/29 patients (86.2%) and 19/29 patients (65.6%) fulfilled at least three and four criteria, respectively. CONCLUSION A predilection for male gender and Indian ethnicity were noted in our study. The diagnosis of CRP was often made clinically, and investigations were mainly ancillary. The treatment response was poor with antifungal agents but excellent with tetracyclines. The diagnostic criteria proposed by Davis et al. were found to be useful in our cohort of patients.

Abstract
Oncocytic papilloma (OP) of nasal cavity and paranasal sinuses are uncommon. We report 3 cases of oncocytic papilloma arising in the nasal cavity and paranasal sinuses, and review the relevant literatures. Unilateral sinonasal lesions are the main clinical manifestation. Pathological feature is multiple layers of epithelial cells. The cytoplasm contains abundant eosinophilic granular and microcapsules filling with mucus. The neutrophils aggregate in the microcapsules which form microabscess. The tendence of recurrence and malignant transformation are the biological character. The best treatment choice is surgical excision completely, and long-term postoperative follow-up is necessary to prevent relapse.

Abstract
Early diagnosis is the key for the successful treatment of breast cancer. A serum marker for the early detection of breast cancer could significantly reduce breast cancer morbidity and mortality by bringing the time of diagnosis at an earlier and therefore still curable stage. So far, no biomarker for the early detection is available for the clinical routine. The aim of the present study was to evaluate the use of calponin-h2 as a blood-based biomarker for the early diagnosis of this disease. Using two monoclonal antibodies against calponin-h2, we developed a sandwich ELISA to analyze the serum levels of calponin-h2. In order to evaluate the diagnostic potential of this biomarker, patients with breast cancer (n = 76), benign diseases of the breast (n = 51) and healthy females (n = 24) were analyzed. Serum levels above 10 ng/ml were only observed in patients with breast cancer (n = 8; 10.5%). Further large-scale studies and preanalytic evaluations are necessary to clarify the definite role of calponin-h2 as a biomarker in breast cancer management.

Abstract
The Chelonid fibropapilloma-associated herpesvirus (CFPHV) is hypothesized to be the causative agent of fibropapillomatosis, a neoplastic disease in sea turtles, given its consistent detection by PCR in fibropapilloma tumours. CFPHV has also been detected recently by PCR in tissue samples from clinically healthy (non exhibiting fibropapilloma tumours) turtles, thus representing presumably latent infections of the pathogen. Given that template copy numbers of viruses in latent infections can be very low, extremely sensitive PCR assays are needed to optimize detection efficiency. In this study, efficiency of several PCR assays designed for CFPHV detection is explored and compared to a method published previously. The results show that adoption of a triplet set of singleplex PCR assays outperforms other methods, with an approximately 3-fold increase in detection success in comparison to the standard assay. Thus, a new assay for the detection of CFPHV DNA markers is presented, and adoption of its methodology is recommended in future CFPHV screens among sea turtles.

Abstract
Confluent and reticulated papillomatosis (CRP) is a relatively rare disorder of unknown origin, mostly affecting young female adults. We here present the case of a 21-year-old male patient with confluent and reticulated papillomatosis. Skin examination revealed brownish, verrucous, hyperkeratotic, 2 to 5 mm papules, which formed confluent patches and plaques with a reticulate network on the interscapular area. The patient was initially treated with ketoconazole cream for two weeks without improvement. The disease can be rather persistent and resistant to topical therapy. Our case showed a satisfactory response to treatment with azithromycin. Although this treatment is known to be effective in some cases, the action mechanism of azithromycin on CRP is not fully understood.

Abstract
Mouth and oropharynx cancer constitute 5% of all malignancies; 95% of them are head and neck squamous cell carcinomas. Carcinogenesis is a multifactor process. Mutagenesis is also determined by the human papilloma virus which has recently been found to be etiologically associated with 20 to 25% of head and neck squamous cell carcinomas, mostly in the oropharinx. Focal fibrous hyperplasia of the connective tissue comes up as an answer to a chronic irritation in which a big amount of collagen can be found. As there exist certain clinical resemblance between squamous cell papilloma, fibrous focal hyperplasia and other mesenchimal tumors it is recommended to proceed, always, with removal and study. Two cases, one of an oral papilloma and another of a focal fibrous hyperplasia in pediatric patients, treated with an Er,Cr:YSGG laser wave length (mu) of 2780 nm are presented.

Abstract
AIM To correlate the radiologic findings with percutaneous transhepatic cholangioscopy (PTCS) in patients with pathologically confirmed biliary papillomatosis. METHODS Thirteen patients diagnosed with pathologic papillomatosis or intraductal papillary neoplasms of the bile ducts were retrospectively reviewed. The imaging results from ultrasonography, multi-detector computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiopancreatography (MRCP) and percutaneous cholangiography (PTC) were correlated with the findings of PTCS. RESULTS Papillary neoplasms of the bile ducts usually appeared on ultrasound as a non-shadowing echogenic mass (60%) within dilated bile ducts. Localised dilatation of the bile duct with mild enhancing nodularities was the most common multi-detector CT finding (61.5%), followed by localised biliary dilatation with mild wall thickening (15.4 %). MRCP showed that the bile duct was locally dilated and filled with material of intermediate signal intensity (60%). An abnormal filling defect (71.4%) was the most common finding when PTC was used. In six patients who underwent PTCS, underlying fish egg-like intraluminal nodularities were noted with or without multifocal cauliflower-like papillary masses. In nine cases, the pathologic finding was intraductal papillary cholangiocarcinoma in the underlying biliary papillomatosis. Three patients were diagnosed as papillomatosis with high grade dysplasia and one as villous adenoma with underlying papillomatosis. CONCLUSIONS Imaging is useful for detecting bile duct tumours that cause obstruction, but its ability to detect fine features of intraductal papillary tumours is limited. Percutaneous transhepatic cholangioscopy is an effective approach that allows the direct visualisation and tissue confirmation of growing papillary tumours.

Abstract
BACKGROUND Bladder papillomatosis is a diffuse tumor proliferation even up almost all of the bladder mucosa. We analyzed prognosis of this rare entity after conservative treatment. METHODS We retrospectively analyzed epidemiological, clinical, therapeutic and evolutive data in 24 patients with newly diagnosed bladder transitional cell carcinoma papillomatosis. All patients underwent a complete endoscopic transurethral resection (TUR) with curative intent. A second look was performed within 30 days. The intravesical therapy regimen consisted on weekly instillations for 6 weeks, and then monthly for 6 months. If the tumor recurred without muscle invasion, TUR was repeated with a second intravesical BCGtherapy regimen. Parameters investigated included age, gender, risk factors, cystoscopic findings (aspect, multiplicity and location of bladder lesion), tumor stage, tumor grade, recurrences and progression times from diagnosis to last follow up. RESULTS The mean age of the patients at initial diagnosis was 64,9±6,1 years. They were males in 23 cases. Initial cancer staging was as follow: pTa (n=6) and pT1 (n=18). The recurring tumors were reported in 17 patients (70,8%). They were stage Ta in 5 patients and stage T1 in 12. The median interval of time between the initial TUR and the first recurrence was 10,3 months. Six patients remain tumor free. From the 17 recurrences, 6 patients developed progression with muscle invasion in 4 of them. Radical cystectomy with ileal conduit was performed in 3 patients and one patient died before radical treatment. Univariate analysis didn't reveal any prognostic factor: age (p=0,7), tumor location and aspect (p= 0,7 and p= 0,5 respectively), tumor stage (p=0,7) and grade (p=0,09). CONCLUSION TCC bladder papillomatosis is a rare entity. TUR with intravesical BCG therapy may be indicated as a first option despite correct follow up. Radical cystectomy should be considered in cases of recurrent or non-resectable tumours.

Abstract
Many lesions in the oral cavity may present with a papillary or pebbly clinical appearance. Although the great majority of these papillary lesions are histologically diagnosed as squamous or viral papillomas, there are occasional cases of other more unusual possibilities. Angiokeratomas are uncommon vascular lesions that often present clinically as papillomas. They may also present with other varying clinical appearances that range from pigmented lesions to hemangiomas. However, all forms demonstrate a characteristic microscopic appearance consisting of hyperkeratotic, hyperplastic epithelium covering connective tissue with abundant blood vessels that are sharply confined to the connective tissue papillae. Angiokeratomas generally involve the skin and are often associated with an underlying systemic metabolic disease such as Fabry's disease or fucosidosis. Patients with these systemic diseases may have multiple lesions, with possible involvement of the oral mucosa. However, solitary lesions involving only the oral cavity are rare; only eight previous cases have been documented. In this paper, we describe a case of solitary angiokeratoma presenting as a papillary lesion on the ventral tongue of an 18-year-old male. The lesion was surgically excised and no recurrence has been reported to date. Although this patient had no other lesions or systemic issues, we stress the importance of evaluating a patient with a diagnosis of angiokeratoma of the oral cavity for underlying systemic metabolic disease.

Abstract
OBJECTIVE To study sinonasal papilloma patients in terms of clinical characteristics, treatment, outcome, and complications. MATERIAL AND METHOD A retrospective descriptive study was done. Sinonasalpapilloma data were gathered between 1999 and 2009. There were 63 available patients from the 82 cases. RESULTS There were nine cases of nasal papilloma (14.3%) and 54 of inverted papilloma (85.7%). The mean age of the inverted papilloma group was higher than the nasal papilloma group (54 +/- 12.97 years vs. 42.4 +/- 24.8 years). The most common symptom was unilateral nasal obstruction. There were three cases of synchronous malignancy in the inverted papilloma and two metachronous (9.3%). Thirty-nine patients (72%) could be followed-up for more than three months. Recurrence was more common in the inverted papilloma group than nasal papilloma (37% vs. 11.1%). The 50% recurrent time of the endoscopic group was 51 weeks and the external group was 14 weeks. The recurrence of the external approach group was 1.59 times the endoscopic group. Ten surgical complications were found in eight inverted papilloma patients (16%) and included three in the endoscopic and five in the external group. Most of them were minor They were hypoesthesia and epiphora. CONCLUSION Sinonasal inverted papilloma was common, able to recur and associated with malignancy. Though this was a limited retrospective study, it showed lower recurrence on the endoscopic approach. The life-long follow-up is needed in all cases.

Abstract
The objective of the present overview was to analyse the available data on etiology, pathogenesis, diagnostics, and treatment of laryngeal papillomatosis. It is shown that the pathogenetic mechanism underlying the development of this pathology is related to cell proliferation mechanisms. The human papilloma virus is most effectively identified by the polymerase chain reaction technique in combination with in situ hybridization. It is expected that new and more informative criteria for diagnostics, treatment,and prognosis of laryngeal papillomatosis will be proposed based on recent progress in molecular biology, morphology,and immunology. Different variants of the therapeutic strategy for the treatment of laryngeal papillomatosis are described.Modern practice of the management of laryngeal papillomatosis takes advantage of the three main approaches and/or their combination. First, further improvement of surgical techniques, such as the application of endoscopic devices and surgical lasers.Second, the search for new pharmaceutical agents (indole-3-carbinol, cidofovir, antiviral medicines, etc.) most frequently used for adjuvant therapy. Third, the development of new vaccination methods. Besides these three approaches, photodynamic therapy and the use of ionizing radiation are currently being studied as the tools for the treatment of extensive and recurrent laryngeal papillomatosis as well as the methods of laser-induced interstitial thermotherapy.

Abstract
Vestibular papillomatosis (VP) is a benign condition of the female genitalia that may be mistaken for condyloma acuminatum (genital warts). In contrast to condylomata, lesions of VP each grow from a distinct mucosal insertion; match the color of the surrounding mucosa; and are symmetrically distributed, limited to the inner labia minora and vaginal introitus. Recognition of this entity will help to prevent unnecessary stress, testing, and discomfort.

Abstract
CONCLUSIONS The GlideScope® Video Laryngoscope (GVL) provides a successful method for obtaining adequate visualization of the larynx in patients with difficult laryngeal exposure (DLE). Although the GVL is far from an ideal laryngoscope for laryngeal surgery because of its low image quality and narrow curved operation space, valuable concepts regarding its development can be used for designing a new laryngoscope specifically for otolaryngology. OBJECTIVE DLE is a problem characterized by poor visualization of the larynx due to a combination of anatomic and clinical conditions. With respect to DLE, no consensus has been reached as to which alternative method should be used when direct laryngoscopy fails. This study focused on the management of DLE cases using the GVL to achieve adequate laryngeal exposure for phonosurgery. METHODS We used the GVL in conjunction with a set of specially designed endolaryngeal instruments in six cases for which traditional rigid laryngoscopy could not provide visualization of the larynx. RESULTS Using the GVL, full visualization of the larynx was obtained in all patients with minimal need for excessive internal or external pressure. Manipulations to remove simple lesions or perform a biopsy were carried out successfully. All of the surgeries were completed with excellent visualization and without any major complications.

Abstract
OBJECTIVE Inverted papilloma of the urinary bladder is an uncommon urothelial neoplasm that may be specially difficult to distinguish from urothelial carcinoma. METHODS Two patients with obstructive symptoms and hematuria have been studied. In the transurethral resection, accidentally, one showed a papillary lesion in the context of nodular hyperplasia of the prostate, where as the other showed a polypoid tumor of the urinary bladder RESULTS Histologically, in both cases, a bladder inverted papilloma was demonstrated, originating from the surface transitional epithelium. Basal cells exhibited peripheral palisading pattern in the trabecular form. In the glandular type, Dogiel or umbrella cells into the gland-like structures, were recognized. Immunohistochemical stains for p53 and Ki-67 were negative. Umbrella cells were positive for cytokeratin 20. CONCLUSIONS Two cases of bladder inverted papilloma with relevant morphological aspects are presented, which we consider useful for the differential diagnosis with urothelial carcinoma.

Abstract
We report a rare case of pulmonary squamous papilloma. A 42-year-old woman was referred to our hospital complaining of dry cough. A chest computed tomography (CT) showed a mass shadow in the lower lobe of left lung. Serum concentrations of carcinoembryonic antigen (CEA) and squamous cell carcinoma-related antigen (SCC) were elevated to 13.0 ng/ml and 11.8 ng/ml, respectively. The mass was positron emission tomography( PET)-positive, with a maximum standard uptake value( SUVmax) of 11.55, suggesting a malignant neoplasm. Under the guidance of video-assisted thoracoscopy, left basal segmentectomy was performed. Intra-operative diagnosis was a squamous papilloma and no malignancy. Her postoperative course was uneventful. She is currently alive without any sign of recurrence.

Abstract
BACKGROUND Neurofibromatosis type I, or Recklinnghausen disease, is the most frequently occurring neurofibromatosis, in 1/3000-11,5000 of children born. This disease is a genodermatosis with 1/3000-1/5000 autosomal dominant transmission. Incriminated in the pathological appearance of the disease gene is located on chromosome 17, gene product, neurofibromina, is a protein involved in controlling cell differentiation and proliferation. Skin manifestations can be associated with the same papillary tumors and the internal organ. Treatment is surgery for larger tumors. Worse prognosis in malignant developpment, with the lower quality of life in the presence of complications, as in this case: mechanical obstructive jaundice. MATERIAL AND METHOD Patients aged 75 years, admitted for obstructive jaundice (progressive, pruritic), cutaneous papillomas (0.5-3 cm) on the trunk and several hyperpigmented brown spots (5-6 cm diameter). Cutaneous lesions (45 years old) have been previously diagnosed by histological examination. RESULTS We did surgery under general anesthesia: cholecystectomy, intraoperative choledocoscopy of bile duct. In the last portion of bile duct we found pedicled tumors. We did partial excision of tumors and coledoco-duodenoanastomosis in healthy tissue. Histological examination showed neurofibrodermatoza type I. Discharge 12 days postoperatively. CONCLUSIONS Preoperative diagnosis suggested the possibility of mechanical jaundice by malignancy. Etiologic diagnosis of this rare form of obstructive jaundice could not be established before surgery, only by histological examination of the excised tumors.

Abstract
INTRODUCTION The human papilloma virus (HPV) can cause laryngeal papillomatosis in childhood. The aetiology is thought to be vertical transmission. Clinically these children are usually asymptomatic for the first 6 months of life. As the papillomas develop locally, symptoms begin to develop. The symptoms range from voice change to frank hoarseness, and 'noisy' breathing, most commonly inspiratory stridor. METHOD Clinical images from microlaryngoscopy and bronchoscopy over a 12-year period were assessed for laryngeal papilloma. RESULTS In Leeds seven cases presented to the specialist centre over the past 12 years, the average age at presentation was 6.8 years and duration of onset of symptoms to specialist review was 21 months. Five of the children had been treated for asthma and two presented in extremis. CONCLUSION The take home message for clinicians is hoarse voice associated with shortness of breath needs specialist referral.

Abstract
BACKGROUND Müllerian papilloma is a rare benign tumor of the female genital tract. It mostly affects girls less than five years old. After the treatment long-term follow-up is needed as there is a chance of recurrence, but even then the prognosis is excellent. CASE A 19-year-old girl with Proteus syndrome presented with vaginal bleeding. The histological examination revealed Müllerian papilloma of the uterine cervix and large bilateral ovarian cystadenomas. The patient was treated with a radical operation, because there were signs of more aggressive behavior in the tumor. The patient is alive and free of disease five years after the operation. CONCLUSION The medical care of patients affected by rare disorders depends heavily on experiences gained from cases published in the medical literature. Since there is not much experience with tumors in Proteus syndrome we believe that this case can aid in shedding light on this subject.

Abstract
UNLABELLED Recurrent respiratory papillomatosis causes significant morbidity among affected children and usually requires frequent surgeries. We present a prospective case series including nine children at a Mexican tertiary referral center. All enrolled patients had severe disease that had required at least four surgical procedures, with a median of 6. Two children had tracheobronchial involvement, one had lung parenchymal disease, and one had a tracheostomy performed during his first surgery. OBJECTIVE To assess the efficacy of intralesional cidofovir in lowering the surgery rate. STUDY DESIGN Prospective case series. SETTING Tertiary referral center in Mexico City. METHODS Nine Mexican children with severe disease were enrolled. Intralesional cidofovir was applied after surgical debulking at a concentration of 5 mg/mL with a four to six week interval. RESULTS Six of the nine patients had a notable decrease in the rate of surgeries, with three patients remaining disease-free with follow up ranging from 1.8 to 3.3 years. No patient demonstrated laboratory abnormalities. Two patients showed moderate and mild dysplasia on papilloma biopsy distinguished by a lack of epithelial maturation with no mitoses or cellular atypia. Two patients died several months after the last injection. CONCLUSIONS Intralesional cidofovir appears to be effective in the treatment of recurrent respiratory papillomatosis, although further studies are required to determine its safety.

Abstract
An animal model for the early detection of common fatal diseases such as ischemic diseases and cancer is desirable for the development of new drugs and treatment strategies. Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that regulates oxygen homeostasis and plays key roles in a number of diseases, including cancer. Here, we established transgenic (Tg) mice that carry HRE/ODD-luciferase (HOL) gene, which generates bioluminescence in an HIF-1-dependent manner and was successfully used in this study to monitor HIF-1 activity in ischemic tissues. To monitor carcinogenesis in vivo, we mated HOL mice with rasH2 Tg mice, which are highly sensitive to carcinogens and are used for short-term carcinogenicity assessments. After rasH2-HOL Tg mice were treated with N-methyl-N-nitrosourea, bioluminescence was detected noninvasively as early as 9 weeks in tissues that contained papillomas and malignant lesions. These results suggest that the Tg mouse lines we established hold significant potential for monitoring the early onset of both ischemia and carcinogenesis and that these lines will be useful for screening chemicals for carcinogenic potential.

Abstract
Biliary papillomatosis is a disease characterized by multiple papillary tumours of variable distribution and extent in the intrahepatic and/or extrahepatic biliary tree. Papillary carcinoma can develop within these lesions. Because biliary papillomatosis is a rare biliary pathological entity, its clinical features and outcome are not well known. The course of this disease is very prolonged. This diagnostic difficulty is due above all to the problematic distinction between biliary papillomatosis and cholelithiasis. Therapeutic strategy should be decided pre-operatively among resection, transplantation or stent. In many cases surgical strategy is decided during surgery, considering the mass extension, the local infiltration and the patient's age, and, when possible, with the aid of extemporaneous histological examination. Recently we experienced a case of biliary papillomatosis of the common hepatic duct in a 82-year-old man, presented with obstructive jaundice and pain in the right upper quadrant and epigastrium radiated to the ipsilateral scapula. First we made cholecystectomy and we positioned the T-tube. The follow-ups performed with laboratory tests and T-tube cholangiogram showed no jaundice but the filling defect in the common bile duct was still present. So we performed a resection of the common bile duct and an hepatico-jejunostomy at the hepatic pedicle. The histological examination showed a villous adenoma of the common bile duct with high-grade dysplasia.

Abstract
Juvenile papillomatosis of the breast ("Swiss cheese disease'') is a benign localized proliferative condition of the breast which occurs almost exclusively in young adult women. Patients with this lesion often have a family history of breast carcinoma, but rarely carcinoma may coexist with the lesion at the time of diagnosis. We present a case of a young male with juvenile papillomatosis of the breast. The pathology and clinical management of this rare lesion is discussed.

Abstract
OBJECTIVE To summarize the experience in diagnosis and treatment of primary tracheal tumors, and to improve the life quality of patients. METHODS Sixty-three patients with primary tracheal tumors treated in the First Affiliated Hospital of China Medical University during the past 40 years were included in this study, among them, there were 42 cases of malignant tumors and 21 cases of benign tumors. The 61 patients underwent surgery including tracheal sleeve resection (22), carinal resection and reconstruction (6), semi-carinal resection and reconstruction (6), tracheal resection for tracheal tumors (17); tracheostomy (4), tracheal resection, partial resection of the thyroid (goiter) and esophagomyotomy (1), tracheal tumor resection and vertical hemilaryngectomy with reconstruction of laryngeal ventricle and trachea by sternocleidomastoid flap (2), cervical trachea and laryngeal resection (1), and carinal scrape (2). RESULTS Fifty-five patients had an uneventful recovery. Eight patients suffered from postoperative complications, among them 3 patients died postoperatively. CONCLUSIONS Primary tracheal tumors often present atypical symptoms, are easily misdiagnosed and with poor prognosis. The main aim of treatment remains to remove the airway obstruction.

Abstract
The juvenile papillomatosis is a rare entity. We shall systematically check for a cancer. A 20-year-old woman patient without any familial medical history of breast carcinoma, was presenting a voluminous nodule of the left breast. A core needle biopsy allowed to diagnose papilloma. A conservative surgical treatment was proposed and realized despite any possibility of complete resection. Histological examination of the surgical specimen concluded to a juvenile papillomatosis. A closed follow-up was proposed to the patient. This case illustrates the difficulty of a voluminous tumor surgery on a young woman. The main problem is to combine the cosmetic constraints with oncology risk.
