Papilloma, Inverted*

This middle-aged woman presented for the first time to ENT clinic with a complaint of nasal stuffiness. Computed Tomography (CT) of the paranasal sinuses was performed following clinical review that revealed a left intranasal mass. Due to a radiological suspicion of an inverted papilloma, Magnetic Resonance Imaging (MRI) of the paranasal sinuses was performed. This, combined with endoscopic biopsy confirmed an inverted papilloma. Following referral to oral maxillofacial surgery (OMF), 3D modelling was performed using the original CT data to aid surgical planning.

OBJECTIVE: This article describes use of the osteoplastic technique in the treatment of maxillary benign tumors. This procedure yielded favorable outcomes in situations where the tumor was difficult to remove using the standard endoscopic approach. METHODS: This study included six sinuses of six patients with maxillary sinus benign tumors (five inverted papillomas and one hemangioma). The tumors were located in the anterior wall of the maxillary sinus and were difficult to remove by the endoscopic approach. The traditional gingivobuccal incision was performed to expose the anterior maxillary sinus wall. A rectangular bone flap was designed on the anterior maxillary wall and a bony window was made using a reciprocating saw. After eradicating all lesions, the bone flap was repositioned to its original site and fixed with a miniplate. Postoperative paranasal sinus computed tomography was performed after 12 and 24 months. RESULTS: All bone flaps healed without any complications. Patients had succes-sful postoperative outcomes without any complications. In one inverted papilloma case, the lesion recurred and was removed easily with the same procedure. CONCLUSION: The osteoplastic technique is a simple and useful method to eradicate benign lesions in the maxillary sinus due to its good access to the maxillary sinus antrum, optical surgical view, and minimal complications.

Objective: To present a rare case of inverted papilloma of the middle ear in a 77-year old man presenting with an external auditory canal polyp of the right ear. Methods:: Design: Case Report. Setting: Tertiary Private Hospital. Patient: One. Results: A 77-year-old man presenting with external auditory canal mass underwent tympanoplasty with canal wall down mastoidectomy. Histopathologic examination revealed inverted papilloma. Conclusion With only 30 cases reported in the literature, inverted papilloma of the middle ear is a rare disease entity that may mimic other benign conditions such as cholesteatoma. It requires further investigation to devise a rational approach to diagnosis and management. Regular post- operative monitoring is essential due to high recurrence and malignant transformation rate while post-operative radiotherapy remains controversial and requires further investigation

Inverted papilloma of the urinary tract is a rare benign lesion. We report, to our knowledge, the first case of inverted papilloma of the prostatic urethra arising in a juvenile. Our patient was referred for evaluation of painless, gross hematuria and voiding difficulty. Transrectal sonography demonstrated a 1.4 cm papillary lesion on the medial aspect of the prostatic urethra. Cystoscopy showed a solitary, papillary tumor on the prostatic urethra. Transurethral resection was performed and histological examination showed an inverted papilloma.

Nasal inverted papilloma (IP) is a benign neoplasm that may be associated with squamous cell carcinoma (SCC). Several studies have suggested that human papilloma virus 16/18 (HPV 16/18) and p53 are closely related to the pathogenesis of IP with transformation to squamous cell carcinoma (IP-SCC). This study was conducted to investigate the role of HPV 16/18 and p53 in the pathogenesis of IP-SCC using immunohistochemistry. We studied two cases of IP-SCC and 10 cases of IP. None of the IP cases presented positivity for HPV 16/18 or p53 protein. Two cases of IP-SCC showed negative reactions for HPV 16/18. The SCC portion of the IP-SCC showed strong positivity for p53, while the IP portion of the IP-SCC was negative for p53. MIB-1 labeling index (LI) was estimated in the IP cases and the IP-SCC as well. In terms of MIB-1 LI, there was no statistical significance between IP and IP-SCC, and between the IP portion and the SCC portion in the cases of IP-SCC. In conclusion, we believe that alteration of the p53 protein is related to IP with malignant transformation, but further studies are required to investigate the correlation of HPV 16/18 and p53 in the pathogenesis of IP with malignant transformation, and the significance of the MIB-1 LI and p53 as biomarkers in IP.

Inverted vesical papilloma is an uncommon, probably benign neoplasm with distinctive histologic features. It usually presents with hematuria and lower urinary tract obstruction due to hall-valve effect. We report a case of vesical inverted papilloma, which was proved histologically, causing lower urinary tract obstruction.

BACKGROUND AND OBJECTIVES: Oncocytic schneiderian papilloma (OSP) is uncommon benign sinonasal neoplasm that arise from the sinonasal epithelium. Because of its rare incidence, OSP is not well-known by clinicians and report of this disease is uncommon. The aim of this study was to review the pathological features and variations of sinonsasl papillomas and to compare clinical behaviors of Inverted papiloma (IP) with OSP. SUBJECTS AND METHOD: A retrospective review and pathological assessment were performed on 99 sinonasal papilloma patients. Parameters for comparison included the origin site, radiologic finding, recurrence and malignancy rates. Predictive factors for recurrence and malignancy included histological variations of IP versus OSP. RESULTS: Eighty-eight patients (88%) were diagnosed with inverted papilloma and 11 patients (11%) were OSP. Recurrence developed in one patient with OSP (9%) and six patients with IP (7%). Six cases (7%) of carcinoma ex papilloma were seen only in IP. OSP was more often presented as a mixed form with inverted papilloma, rather than in the pure form. The histological variations and radiological findings, regardless of its difference, did not statistically impact recurrence rate and malignant transformation rate. CONCLUSION: The common mixed features of OPS and IP explains that these two lesions have the common etiological factor. In our study, there are no significant differentiations in clinical manifestation and prognosis. A larger number of cases for analysis would be necessary to confirm the properties of OSP.
