1/10. Congenital maxillary sinus cholesteatoma.cholesteatoma of the paranasal sinuses is a rare condition. The purpose of this paper is to present a child with a congenital maxillary sinus cholesteatoma. An 18-month-old girl presented with a 4-week history of right cheek and intraoral swelling. Examination revealed a smooth swelling of the right hard palate in association with the facial swelling in the maxillary region. An inferior meatal antrostomy revealed pultaceous debris in the right maxillary antrum and biopsy confirmed a maxillary sinus cholesteatoma. The inferior meatal antrostomy was enlarged to allow exteriorisation of the disease. recurrence of the disease has not presented on follow-up. An exteriorisation procedure as performed, in child of this age, allows normal facial growth. If recurrence develops then further treatment may be instituted in a more mature facial skeleton.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
2/10. cholesteatoma of the maxillary sinus.cholesteatoma of the maxillary sinus, also known as keratoma, primary epidermoid tumor, epidermoid cyst, and keratocyst, is a rare entity, with a clinical presentation and radiologic findings that are difficult to distinguish from those of malignancy. We report a case of cholesteatoma of the maxillary antrum that occurred in a 12-year-old boy without any history of predisposing factors. Multiple theories of pathogenesis have been proposed throughout history; currently there are two accepted ones. We discuss these theories and present, along with the differential diagnosis, a review of the literature and the characteristic radiologic and pathologic findings. While it is a rare entity, the diagnosis of cholesteatoma should be considered for any slowly expanding lesion of the maxillary antrum.- - - - - - - - - - ranking = 0.33333333333333keywords = cholesteatoma (Clic here for more details about this article) |
3/10. cholesteatoma of the paranasal sinuses: case report & review of the literature.cholesteatoma of the paranasal sinuses is uncommon but makes interesting the differential diagnosis of unilateral sinus masses. When present, it is most often located in the frontal sinus; less commonly in the ethmoids and maxillary sinuses. Its presence elicits a spectrum of symptomatology differing among the varying locations of occurrence. Ultimately, complications of untreated sinus cholesteatoma can lead to severe disfigurement, carcinomatous degeneration or death. A review of this century's English literature revealed only twenty reported cases of cholesteatoma of any paranasal sinus. The distinguishing features of these cases are presented along with our personal experience with a cholesteatoma of the maxillary sinus. Treatment recommendations to avoid long-term complications are the total excision of the cholesteatoma with adequate drainage and sinusotomy for post-operative follow-up. CAT scanning plays an important role in diagnosis and follow-up.- - - - - - - - - - ranking = 0.66666666666667keywords = cholesteatoma (Clic here for more details about this article) |

5/10. Giant invasive cholesteatoma. Report of a case with cerebellar invasion.We present a case of epidermoid cholesteatoma that killed the patient by relentless invasion, despite radical surgery. An autopsy disclosed a focus of dural and cerebellar invasion, which dramatized the aggressive nature of this disease. In fact, the epithelial cells of this disease are not thought to possess the ability to invade. Instead, inflammation is believed to both stimulate the squamous epithelial cells to proliferate and destroy adjacent tissues, thereby providing a pathway for epithelial cell migration. Epidermoid cholesteatoma, then, is a disease in which the processes of inflammation and hyperplasia combine to mimic a neoplasm.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |
6/10. Late recurrence of a frontal sinus cholesteatoma.The longest recorded recurrence of a frontal sinus cholesteatoma with involvement of the orbit, frontal bone, and floor of the anterior cranial fossa is presented. Radical surgery is required and often craniotomy is necessary. Bony reconstruction of defects should not be undertaken until recurrence has not been present for at least a year. A review of the literature and a discussion of the origin of cholesteatomas is given.- - - - - - - - - - ranking = 1keywords = cholesteatoma (Clic here for more details about this article) |

8/10. Primary and secondary keratomas of the frontal sinus.Keratomas in the paranasal sinuses have been described in the world literature with variable frequency and the inaccurate terminology of cholesteatoma. This paper describes an illustrative case and provides a discussion of the etiology and pathology of this disease. Because the pathologic findings are that of a true keratoma, classification of this disease as primary and secondary keratomas is recommended. The classification 1. primary keratoma is recommended for the epidermal cyst of congenital rest origin and 2. secondary keratoma is suggested for epithelial layers and cysts that are secondary to squamous cell implantation or migrations.- - - - - - - - - - ranking = 0.16666666666667keywords = cholesteatoma (Clic here for more details about this article) |
9/10. Mucin impaction tumor of the paranasal sinuses: a new clinical entity?A variety of uncommon benign lesions occur in the paranasal sinuses and have been reported to masquerade as carcinomas. Nearly all of such cases have been limited to the frontal, sphenoid, and ethmoid sinuses with an isolated report of maxillary sinus involvement. The classic roentgenologic picture is that of bony destruction. Heretofore described destructive lesions of the maxillary sinus include the mucocele, mucous retention cyst, pseudocyst, pyocele and cholesteatoma. This report deals with a previously undescribed entity, the mucin impaction tumor located in a septate maxillary sinus. This inflammatory, non-neoplastic tumor-like condition, presents as chronic sinusitis with periorbital edema, malar swelling and tenderness. Radiologic examination reveals total destruction of the bony walls of the nose, of the orbital rim and floor and of the maxillary sinus. The importance of recognizing this lesion lies in its benign nature but destructive capabilities. The destruction may possibly be accounted for by its anatomical origin in the septate sinus. Repeated surgical intervention may also serve to predispose or potentiate development of these lesions. Its resolution after adequate surgical extirpation and its place in the differential diagnosis of antral lesions are worthy of emphasis.- - - - - - - - - - ranking = 0.16666666666667keywords = cholesteatoma (Clic here for more details about this article) |
10/10. Epidermoid carcinoma of the frontal sinus secondary to cholesteatoma.We report a case of primary epidermoid carcinoma of the frontal sinus associated with cholesteatoma. We postulate that the carcinoma is secondary to malignant degeneration of the cholesteatoma. The literature review revealed 38 cases of cholesteatoma of the frontal sinus. Four were associated with carcinoma. To the best of our knowledge, this is the fifth such case in the world literature.- - - - - - - - - - ranking = 1.1666666666667keywords = cholesteatoma (Clic here for more details about this article) |
