1/63. Huge hamartoma with inverted papilloma in the nasal cavity.We report clinical experience in managing a 46-year-old Japanese man with long-standing nasal obstruction resulting from a huge left nasal mass. Computed tomography, magnetic resonance imaging and biopsy were used to make a provisional diagnosis of inverted papilloma. The mass was resected via a frontal approach combined with rhinotomy. Histopathologic examination of the resected specimen was consistent with a hamartoma that included an inverted papilloma on a portion of its surface. In addition to being rare tumors in the nasal cavity, we believe that our patient's tumor the largest nasal hamartoma ever reported.- - - - - - - - - - ranking = 1keywords = papilloma (Clic here for more details about this article) |
2/63. Intracranial extension of inverted papilloma: An unusual and potentially fatal complication.BACKGROUND: The purpose of this article is to define the outcome of intracranial extension of inverted papilloma and outline a rationale for management of this rare clinical presentation. methods: A review of patients with intracranial extension of inverted papilloma reported in the literature (18 patients), or treated in our institution (3 patients ) was performed. The data of these 21 patients were consolidated with regard to clinical presentation, treatment, and outcome. Nine patients, including 1 of our cases, had coexisting squamous cell carcinoma and therefore were excluded from the analysis. Twelve patients with "pure" inverted papilloma formed the basis of this study. RESULTS: The majority of patients (83%) with intracranial inverted papilloma had recurrent disease. patients with extradural disease had a survival rate of 86% with an average follow-up of 4.4 years. Eighty-six percent of these survivors were treated with craniofacial resection. In contrast, 75% of patients with intradural inverted papilloma were dead of disease with an average follow-up of 9.3 months regardless of the treatment modality. CONCLUSIONS: Intracranial extension of inverted papilloma is mostly associated with recurrent disease. Intracranial extradural inverted papilloma can be effectively controlled with craniofacial resection. Intracranial intradural involvement of inverted papilloma has a poor prognosis regardless of treatment. Aggressive treatment of intranasal inverted papilloma may be the most important factor in preventing intracranial presentation.- - - - - - - - - - ranking = 2.1666666666667keywords = papilloma (Clic here for more details about this article) |
3/63. Giant benign sinonasal squamous papilloma: report of a case.We treated a patient with a giant squamous papilloma in the nasal cavity and maxillary sinus that extended through a bony defect into the oral cavity. The mass was excised with a combined endoscopic, Caldwell-Luc, and transoral approach. Lesions of this type are rare, but when they do occur, the rate of recurrence is high. Therefore, long-term followup, including endoscopic examination, is important.- - - - - - - - - - ranking = 0.83333333333333keywords = papilloma (Clic here for more details about this article) |
4/63. Malignancies arising in oncocytic schneiderian papillomas: a report of 2 cases and review of the literature.Oncocytic schneiderian papillomas (OSPs) are uncommon benign neoplasms that arise from the sinonasal schneiderian epithelium. Malignancies arising in OSPs are rare, and, to our knowledge, only 14 such instances have been reported in the medical literature. We report 2 additional cases--a small cell carcinoma and a sinonasal undifferentiated carcinoma arising in OSPs and presenting synchronously with the benign neoplasm. The potential for malignant transformation in OSPs is small, but warrants that these papillomas be completely excised to exclude a coexisting carcinoma.- - - - - - - - - - ranking = 1keywords = papilloma (Clic here for more details about this article) |
5/63. Inverted papilloma of the nasal cavity presenting with massive amounts of squamous metaplastic cells in sputum. A case report.BACKGROUND: Squamous metaplasic cells are rarely seen in sputum of female nonsmokers. CASE: A 47-year-old female nonsmoker presented with massive amounts of squamous metaplasic cells in sputum and an elevated level of squamous cell carcinoma (SCC) antigen in serum present for months, while no causative lesion was detected either by lung computed tomography or bronchoscopy. The patient was eventually diagnosed as having inverted papilloma in the right nasal cavity. Resection of the tumor brought about disappearance of squamous metaplastic cells in sputum and return of serum SCC antigen to the normal range. CONCLUSION: This case clearly demonstrates that squamous metaplastic cells in sputum can originate in lesions in the nasal cavity, although they are rare. It should be kept in mind that the nasal cavity is a potential site producing squamous metaplastic cells in sputum.- - - - - - - - - - ranking = 0.83333333333333keywords = papilloma (Clic here for more details about this article) |
6/63. A rare location of bilateral inverted papilloma of the nose and paranasal sinuses.Inverted papilloma is a rare benign sinonasal tumour, characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin, whereas paranasal sinuses are involved by extension quite frequently. In contrast, primary sinus inverted papillomas have rarely been reported. Although the midfacial degloving approach has historically been the procedure of choice, recent technological advances have rendered endoscopic sinus surgery a safe procedure with equivalent success rates and low probability of papilloma recurrence. We present a rare case of bilateral inverted papilloma arising from the sphenoid septum and extending towards both the sphenoid and posterior ethmoid sinuses and the posterior section of both nasal cavities, while it slenderizes the sella turcica by compression and elevates the pituitary gland. The bilateral inverted papilloma was successfully removed with a transnasal endoscopic procedure. There is no evidence of recurrence for a follow up period of 1.5 years postoperatively. We conclude that it is a rare entity, which can be treated successfully with endoscopic sinus surgery in the hands of an experienced otorhinolaryngologist.- - - - - - - - - - ranking = 1.5keywords = papilloma (Clic here for more details about this article) |
7/63. Hidradenoma papilliferum of nasal skin.Pathologic examination of an excisional biopsy specimen of a subepidermal nodule from the nasal tip of a 37-year-old black man demonstrated papillae covered by eosinophilic columnar epithelial cells, suggesting cylindric cell papilloma or well-differentiated papillary adenocarcinoma of nasal mucosa. The patient did not submit to further investigation of the sinonasal tract but sought attention 15 months later because of local recurrence of the lesion. A protuberant, 3-cm, cystic nodule of the subcutis over the left nasal ala and tip was excised completely and found to have characteristics of hidradenoma papilliferum, an apocrine gland neoplasm most commonly occurring in the anogenital skin of white women. This case demonstrates how easily an apocrine neoplasm arising near a mucocutaneous junction can be confused with a mucosal tumor, potentially leading to inappropriate treatment.- - - - - - - - - - ranking = 0.16666666666667keywords = papilloma (Clic here for more details about this article) |
8/63. Surgical removal of inverted papilloma: case report of endoscopic versus open excision.We describe two cases of nasal inverted papilloma who had different management modalities. Although both were essentially of the same pathology, one underwent endoscopic excision while the other was treated with the more popular lateral rhinotomy and medial maxillectomy. We wish to highlight the different modalities of treatment available for inverted papilloma and a review of published results.- - - - - - - - - - ranking = 1keywords = papilloma (Clic here for more details about this article) |
9/63. Inverted sinonasal papilloma--a report of 31 cases and review of the literature.Inverted papilloma is an epithelial neoplasm of the lateral nasal wall and adjacent sinuses characterized by a marked propensity for recurrence and a significant association with carcinoma. In this retrospective study we present 31 cases treated by our departments between 1982 and 1999. The aim was to compare our results to those of other authors especially regarding surgical management. The male to female ratio of these patients was 2:1 and most patients were in the 6th and 7th decades of life. Conservative surgery was used in most cases as the initial treatment. The overall recurrence rate was low and there were 3 cases associated with carcinoma. We conclude that the results of conservative surgery in selected cases are comparable to those using radical methods. A review of the literature is presented and particular attention is dedicated to the literature concerning analysis of p53 expression, HPV and Epstein-Barr infection and apoptosis in inverted papilloma.- - - - - - - - - - ranking = 1keywords = papilloma (Clic here for more details about this article) |
