Recurrent inverted papilloma coexisted with skull base lymphoma: A case report

BACKGROUND Inverted papilloma is an uncommon neoplasm in the nasal cavity.It is a histologically benign tumor,but has a high recurrence and local invasion rate.In addition,nasal or skull base lymphoma is another rare neoplasm.The coexistence of these two tumors in one case makes the diagnosis and related treatment difficult.CASE SUMMARY We report a case of an immunocompetent patient,who had a history of inverted papilloma 20 years ago.The patient presented with an infiltrated mass lesion in the nasal cavity with extension to the frontal base.The repeated biopsies revealed inverted papilloma without any malignant transformation.After the patient underwent a frontobasal craniotomy with total tumor excision,the final pathological examination revealed nasal inverted papilloma coexisting with diffuse large B-cell lymphoma of the skull base.CONCLUSION Based on this case report,while managing a case of an aggressive recurrent inverted papilloma,not only squamous cell carcinoma transformation,but also other invasive malignancy,such as lymphoma,should be considered.

Clinical Variants, Rates of Post-Operative Recurrence and Malignant Transformation of Sino-Nasal Inverted Papilloma

Background: Inverted Papilloma (IP) is the most common benign neoplasms arising from the mucosal lining of the of the Sino-Nasal tract with single or multifocal attachment sites. The high propensity to recur, local aggressive behavior and possibility of malignant transformation attract considerable interest. Objective: To assess the factors affecting Sino-nasal IP, malignant transformation rate, and post-operative recurrence rate. Methods: A retrospective study was carried out on all cases diagnosed as Sino-Nasal Papilloma between January 2010 and December 2020 at Salmaniya Medical Complex, Bahrain. Data gathered from medical records were analyzed using SPSS. A total of 49 Sino-Nasal Papilloma cases were recorded of which 37 were IP. Factors affecting Sino-Nasal IPs are presented. Results: Sino-Nasal IP was recorded in 37 cases, composed of 28 males and 9 females with first presentation average age of 45.86 years. These involved 20 cases in the left side, 14 in the right side and 3 were bilateral. Recurrence in males and females was found to be 35.7% and 33%, respectively, with an average of 12.6 months. The symptoms include nasal blockage (97.3%), epistaxis and postnasal drip (13.5% each), headache (8.1%) and hyposmia and rhinorrhea (5.4%, each). The main recurrence was at stage T2 (60.5%), while in smokers (26.7%) and non-smokers (50%). Malignant transformation occurred in one patient only (2.6%). Conclusion: IP is the most common type of SNP with male predominance. The recurrence rate is high with an average of a year and the malignant transformation occurred in 2.6 % of the cases.

A Review of Inverted Papilloma at a Tertiary Centre: A Six-Year Experience

Objectives: To evaluate the clinical presentation and treatment outcome of all patients treated for inverted papilloma at the University Malaya Medical Centre, Malaysia. Methods: A retrospective review of 22 patients with inverted papilloma, treated at our centre, from 1st January 2005 to 31st August 2011. The demographic data, clinical features, radiological findings, surgical procedures, recurrent rate and malignant transformation were assessed. Result: The commonest presentation was a unilateral nasal blockage, comprising 77.3% cases. A total of 19 patients had undergone endoscopic surgery while three patients had open surgery performed. The mean duration of the follow-up period was 30.5 months. Seven (31.7%) patients were detected of tumour recurrence during the entire course of follow-up. However, throughout the follow-up period, none had demonstrated malignant transformation. Conclusion: Endoscopic medial maxillectomy is a well-accepted approach in treating inverted papilloma. Nevertheless, open surgery still plays an important role in extensive diseases and in cases of malignancy. Unilateral nasal obstruction is the most important symptom. Repeated pre-operative biopsy or perhaps frozen section of intraoperative biopsies is necessary to avoid misdiagnosis. Krouse stage II disease showed the highest recurrent rate of 18.2%. Lifelong follow-up and emphasis on adherence is mandatory for early detection of recurrence and malignant transformation.

Acute proptosis: Unusual initial presentation of sinonasal inverted papilloma

Inverted papilloma is an uncommon histopathological finding of maxillary sinus tumor. We reported here a rare case of inverted papilloma of maxillary sinus presented initially with ipsilateral proptosis. A middle-aged lady with history of having allergic rhinitis presented with progressive left eye proptosis. Assessment revealed presence of orbital mass arising from paranasal sinus, in which the histopathological examination was initially inconclusive, and later it turned up to be inverted papilloma, partly with malignant transformation. High index of suspicion is necessary especially in those patients with recurrent non-specific sinonasal symptoms, which may need repeated biopsy and histopathological examination. Ocular manifestation signifies a more advance disease.

A Case Report of an Inverted Papilloma of the Prostatic Urethra and a Synchronous Low-Grade Papillary Carcinoma of the Bladder

Inverted urothelial papilloma is a rare benign tumour and represents one of the urothelial lesions with inverted morphology. Accurate diagnosis and differentiation from other inverted lesions is important because its proper clinical management and expected clinical outcomes are distinctly different. Here we describe a case of a large inverted urothelial papilloma of the prostatic urethra and a synchronous non-invasive low-grade papillary urothelial carcinoma of the bladder in a 60 year-old man. We focus on the differential diagnosis of inverted urothelial papilloma.

Use of Diode Laser in Excising Bilateral Inverted Papilloma of Paranasal Sinuses

The inverted papilloma is an uncommon unilateral benign unilateral tumor of the nose & paranasal sinuses. Although a benign pathology, it is associated with aggressive local destruction and recurrence after removal and malignancy. The clinical picture presents non-specific signs and symptoms, such as unilateral nasal obstruction, anosmia and headache. Treatment is essentially surgical. This report has the objective of presenting an uncommon bilateral nasal inverted papilloma and the use of diode laser in surgical excision & making a literature review. The uniqueness in our case was the use of diode laser in excision of inverted papilloma.

Value of magnetic resonance imaging including dynamic contrast-enhanced magnetic resonance imaging in differentiation between inverted papilloma and malignant tumors in the nasal cavity

Background Distinguishing inverted papilloma （IP） from malignant tumors in the nasal cavity is difficult in a substantial number of cases,thus hindering the administration of appropriate therapeutic strategies.This study aimed to evaluate whether magnetic resonance imaging （MRI）,including dynamic contrast enhanced MRI （DCE-MRI）,could improve differentiation between IP and malignant tumors,and to identify which MRI features were the best in discriminating IP from malignant tumors in the nasal cavity.Methods Non-enhanced,static,and dynamic contrast enhanced MRI was performed in 88 patients with an IP or a malignant tumor in the nasal cavity that had been confirmed by histological results.MRI features of IP and malignant tumors including side,margin,T1 signal intensity,T1 homogeneity,T2 signal intensity,T2 homogeneity,lobulation signs,convoluted cerebriform pattern,extra-sinonasal involvement,pattern of enhancement,Tpeak,Tmax,Clmax,and TIC type were evaluated and correlated with histological findings.Results There were significant differences between IP and malignant tumors in T2 homogeneity,Iobulation signs,convoluted cerebriform pattern,extra-sinonasal involvement,Tpeak,Tmax and TIC types.A convoluted cerebriform pattern had a higher sensitivity and specificity in diagnosis of IP while washout-type TIC had a higher sensitivity and specificity in diagnosis of malignant tumors in the nasal cavity.Non-enhanced combined with static and dynamic enhancement MRI was significantly superior to non-enhanced combined with static enhancement MRI in the differentiation of IP and malignant tumors in the nasal cavity.Multivariate logistic regression analysis identified that the best MRI features were a convoluted cerebriform pattern,extra-sinonasal involvement,and washout-type TIC for both observers （Wang XY and Zhang ZY）.Conclusion Non-enhanced and static combined with dynamic contrast-enhanced MRI improves differentiation of IP and malignant tumors in the nasal cavity.

Increased expression of fascin associated with malignant transformation of sinonasal inverted papilloma

Background Fascin, an actin binding protein, usually expressed at a low level in normal epithelium, but is significantly increased in transformed epithelial cells and several common carcinomas. In this study, we examined the expression of fascin by immunohistochemistry in sinonasal epithelium with chronic inflammation （control group）, exophytic papilloma （EP）, inverted papilloma （IP） with dysplasia and cancerated IP （including caminoma in situ and invasive squamous cell carcinoma, SCC）, and furthermore investigated the relationship between fascin expression and formation of malignant IP. Methods Fascin expression was immunohistochemically detected using monoclonal antibody against fascin in 86 paraffin embedded tissues, including 10 cases of sinonasal mucosa with chronic inflammation, 10 of EP, 45 of IP with dysplasia （45 cases were divided into three groups： IP with mild dysplasia, IP with moderate dysplasia, and IP with severe dysplasia, 15 cases each）, and 21 of cancerated IP. Results The level of fascin expression was significantly higher in the neoplastic tissue than that in control group. Fascin expression increased gradually with the progression from sinonasal epithelium with chronic inflammation, IP with mild dysplasia, IP with moderate dysplasia, IP with severe dysplasia, to cancerated IP, and significant difference of fascin expression was observed between any two groups of the five. Conclusion Precancerous lesions of IP exhibit elevated levels of fascin that may be associated with carcinogenesis of IP. Fascin may play a role in the formation of IP and EP.

Etiology of sinonasal inverted papilloma: A narrative review

Objective:Sinonasal inverted papilloma (IP) is a benign and uncommon tumor of the nasal cavity and paranasal sinuses with a tendency for recurrence and even malignant transformation.Though the morphology and clinical behavior of this lesion has been well described,its etiology remains controversial.Methods:Computerized searches were performed in PubMed,Scopus,and Google scholar through May 2015.In this review,etiologic factors including human papilloma virus (HPV),Epstein-Barr virus (EBV),cell cycle related proteins and angiogenic factors,occupational and environmental exposures,and chronic inflammation,will be discussed.Results:Many studies indicate that HPV has been detected in a significant percentage of IP,while EBV has not been shown to be significantly associated.Certain cell cycle regulatory factors and angiogenic proteins contribute to the dysregulation of proliferation and apoptosis,and facilitate migration and tumor invasion.Occupational exposures,such as welding and organic solvents,have been implicated,and smoking seems more critical to recurrence and dysplasia rather than initial IP occurrence.Chronic inflammation may also have a causative relationship with inverted papilloma,but the mechanism is unclear.Conclusions:Though etiology of sinonasal IP remains controversial,the studies reviewed here indicate a role for viral infection,cell cycle and angiogenic factors,environmental and occupational exposure,and chronic inflammation.Further study on etiologic factors is necessary for clinical guidance and therapeutic targets.

Survival Outcome of Squamous Cell Carcinoma Arising from Sinonasal Inverted Papilloma

Background： Sinonasal inverted papilloma （IP） is a rare benign tumor of the nasal cavities and paranasal sinuses. It is destructive or bone-rcmodeling, tends to recur alter surgical resection, and has a significant malignant potential. The present study aimed to pertbnn a retrospective analysis of patients with squamous cell carcinoma （SCC） arising from IP, including characteristics, survival outcome, and predictors of associated malignancy. Methods： The medical records of 213 patients diagnosed with IP from January 1970 to January 2014 were retrospectively reviewed. Eighty-seven patients were diagnosed with SCC/IP; their clinical characteristics, treatments, and survival outcomes were analyzed. Results： Of the 87 patients with SCC/IP, the 5- and 10-year overall survival outcomes were 39.6% and 31.8%, respectively. Twenty-nine of these patients received surgery and 58 received combined surgery and radiation. Of the patients with stages III-IV, the 5-year survival rate was 30.7% for those treated with surgery only and 39.9% for those given the combination treatment （P = 0.849）. Factors associated with significantly poor prognosis were advanced-stage, metachronous tumors, or with cranial base and orbit invasion. Age, synchronous or metachronous tumors, and pathological stage were independent risk factors for mortality, shown by multivariate analysis. Conclusion： Patients with SCC/IP had low overall survival outcomes. Advanced age, stage, and metachronous tumors are the main factors affecting prognosis. Treatment planning should consider high-risk factors to improve survival outcome.

The pathology of urinary bladder lesions with an inverted growth pattern

Inverted lesions in the urinary bladder have been the source of some difficulty in urological pathology. The two common ones are von Brunn＇s nests and cystitis cystic/cystitis glandularis, which are considered normal variants of urothelium. Apart from them, a number of other rare urothelial lesions with inverted growth pattern occur in the urinary bladder. Some of them are only reactive conditions, just as pseudocarcinomatous hyperplasia. Some are benign tumors, namely inverted papilloma. Whereas others are malignant neoplasms, including inverted papillary urothelial neoplasm of low malignant potential （PUNLMP）, non-invasive inverted papillary urothelial carcinoma （low-grade and high-grade）, and invasive urothelial carcinoma （inverted, nested and big nested variants）. Because of the overlapping morphological features of all the inverted lesions mentioned above, even between high-grade invasive carcinoma and psendoearcinomatous hyperplasia which are only a kind of reactive conditions, it is very important for the surgical pathologist to recognize and be familiar with these inverted lesions in urinary bladder. In this article, we review these spectrums of inverted lesions of the urinary bladder. Emphasis is placed on histogenesis, morphology, differential diagnosis of these lesions, and the pathologic grading of the non-invasive inverted neoplasms, such as inverted papilloma, inverted PUNLMP, non-invasive inverted papillary urothelial carcinoma with low-grade, and non-invasive inverted papillary urothelial carcinoma with high-grade.

Benign Nasosinus Tumors: Epidemiological, Clinical, Morphological, Therapeutic, and Evolutionary Aspects at the Adolphe SICE General Hospital in Pointe-Noire (Congo-Brazzaville)

Introduction: Benign nasosinus tumors (BNST) of epithelial origin are relatively rare and arise from the various lining tissues of the nasal and sinus cavities, and from glands developed from these epithelial invaginations. These include nasosinusal polyps, pleiomorphic adenoma and inverted papilloma. The aim of our study was to investigate the epidemiological, clinical, morphological, therapeutic, and evolutionary particularities of these three clinical entities, including two tumors with the potential for progressive malignancy (pleiomorphic adenoma and inverted papilloma) and one strictly benign tumor with a favorable evolution (nasosinus polyp or Schneider polyp). Materials and Methods: This was a retrospective, analytical, cross-sectional study conducted from January 1, 2006 to December 31, 2019 (13 years), in the Department of Otolaryngology and Cervicofacial Surgery at Adolphe SICE Hospital, Pointe-Noire, Congo-Brazzaville. Results: During the study period, 74 patients were registered for a nasosinus tumor, of which 23 were benign tumors of epithelial origin (31%) distributed as follows: 15 cases of nasosinus polyp, 5 cases of pleomorphic adenoma and 3 cases of inverted papilloma. The mean age was 42.5 for polyps, with an estimated median of 38, and 42.9 for the other two entities (pleomorphic adenoma and inverted papilloma), with an estimated median of 41. Nasosinus allergy accounted for 17% of cases, followed by chronic sinusitis (12%);however, in 49% of cases, the patient’s history was not specified. There was no sexual predominance, the sex ratio being 1.08. Occupation, socio-economic level, and education had no impact on the development of these tumors. Most of our patients (52%, 12 cases) had a consultation delay of more than one (1) year, whatever the histological nature of the tumor. The complete nasosinus syndrome (NSS) included nasal obstruction, rhinorrhea, epistaxis, and anosmia, and was found in 19 cases (83%), most often reflecting a nasosinus polyp. CT scans were performed in all patients, with hyperdense images predominating in 22 cases. Management of benign nasosinus tumors was mainly surgical. Postoperative management was straightforward in 15 cases (65%). Conclusion: Benign nasosinus tumors are dominated by nasosinus polyps. Management of these tumors is essentially surgical, with the best clinical outcome.
