1/164. rhinosporidiosis presenting with two soft tissue tumors followed by dissemination.

    rhinosporidiosis is caused by rhinosporidium seeberi. Most mycologists believe that R. seeberi is either a Chytridium related to the Olpidiaceae (order Chytridialis, class Chytridiomycetes) or a Synchytrium. This is the first documented case of tumoral rhinosporidiosis in a Sri Lankan and the third documented case in the world literature. A 44 year old male presented with a large mass above the thigh and a similar mass over the anterior chest wall, both masses contained R. seeberi. Later examination of the patient revealed nasal polyps, confirming that the tumors were due to systemic spread of this infection.

2/164. A proposal for a staging system for hyperplastic rhinosinusitis based on the presence or absence of intranasal polyposis.

    This study of 30 patients with hyperplastic rhinosinusitis reveals that the major determinant of the success or failure of conservative therapy is the presence or absence of intranasal polyposis. When polyposis is confirmed both clinically and radiographically, surgical intervention appears to be the rational way to handle most cases. When intranasal polyps are not present, an aggressive medical regimen is called for, one that includes a short-term, low-dose oral corticosteroid and an antibiotic, along with periodic radiographic assessment. Regardless of how much disease is seen on computed tomography, if it does not also detect intranasal polyps or masses, the potential for clearing with conservative therapy is extremely high.

3/164. Detection of activated eosinophils in nasal polyps of an aspirin-induced asthma patient.

    aspirin-induced asthma (AIA) is frequently accompanied by nasal polyps. Eosinophil infiltration is a characteristic feature of nasal polyps associated with AIA. Even though steroids are well known to be effective on managing AIA and its nasal polyps, histochemical examinations after steroid therapy and at recurrence, involving eosinophil infiltration of nasal polyps, have been less studied. To know the histochemical effects of steroid treatment on eosinophil accumulation in nasal polyps of AIA and the histochemical feature of a recurring polyp and to detect distributional differences between storage and secreted forms of eosinophil cationic proteins, we carried out immunocytochemical labelling with antibodies against EGI (recognizing resting and activated eosinophils) and EG2 (recognizing only activated eosinophils), and determined eosinophil infiltration in nasal polyps that were obtained before and after steroid treatment, and at recurrence of polyps. A large number of eosinophils in AIA polyps were found before steroid treatment and at recurrence, and they were predominantly composed of activated eosinophils (EG2-positive). In contrast, eosinophil infiltration was rare in polyps obtained immediately after steroid treatment. This finding suggests that eosinophil infiltration may be associated with nasal polyp formation in AIA, and that activation of eosinophils plays an important role in accumulation of eosinophils and polyp formation beginning with the initial stage.

4/164. The cystic fibrosis conductance regulator gene exon sequence is normal in a patient with edematous eosinophilic nasal polyps.

    nasal polyps are the most common mass lesions found in the nose and their etiology is unknown. nasal polyps from cystic fibrosis (CF) patients are histologically distinct from nasal polyps from patients without CF. It has been suggested that a mutation (G551D) of the cystic fibrosis transmembrane conductance regulator (CFTR) gene may play a role in nasal polyp formation in patients without CF. To investigate the possibility that this or other CFTR gene exon mutations are required for nasal polyp formation, the CFTR gene exons were sequenced from peripheral blood dna derived from an adult patient with edematous eosinophilic nasal polyps and no personal or family history of CF. No mutations or deletions were identified in any of the CFTR exons. A single polymorphism (A or G) was found in exon 10, base pair 1540, amino acid 470. This polymorphism was detected in 11 of 16 subjects (69%) with edematous eosinophilic nasal polyps and 10 of 21 normal subjects (48%) without nasal polyps and was not statistically significant (p = 0.316). These results demonstrate that mutations of the CFTR coding region are not a prerequisite for the formation of edematous eosinophilic nasal polyps.

5/164. Nasal manifestation of extranodal Rosai-Dorfman disease--diagnosis and management.

    Two cases of Rosai-Dorfman disease with polypoid nasal infiltration mimicking nasal tuberculosis and malignant lymphoma are reported. This rare benign disease was first described by Rosai and Dorfman in 1969 and is characterized by histiocytic proliferation. It is seldom considered in the differential diagnosis of granulomatous diseases due to its rarity and histological similarity to other diseases. Extranodal manifestations of this disease are uncommon. Although no specific treatment can guarantee a sustained remission of this disease, surgery for loco-regional lesions can result in long-term symptomatic control and restoration of function. Both patients underwent endoscopic resection of the nasal polypoid lesions and have subsequently been free of recurrence. Loco-regional infiltration of the nasal cavity by Rosai-Dorfman disease is effectively managed by endoscopic resection.

6/164. An unusual complication of augmentation rhinoplasty: late displacement of dorsal nasal splint.

    Silastic (Dow-Corning) implants are used for augmentation rhinoplasty. Complications following their use usually occur within the first 24 months. We report a case in which the dorsal splint became displaced spontaneously five years after surgery.

7/164. Endoscopically assisted anterior cranial skull base resection of sinonasal tumors.

    The traditional approach to sinonasal tumors involving the base of skull has been the anterior craniofacial resection. Endoscopic techniques have created the potential to approach the intranasal aspect of skull base lesions without external incisions and still develop an en bloc resection when removed. We report our initial experience with skull base neoplasms in which the otolaryngic portion of the standard resection was accomplished instead through an endoscopic approach. The nature of lesions favorable for this approach and associated technical issues are discussed. Although we do not consider this approach a replacement for the traditional anterior craniofacial resection, it is an important adjunct in the skull base surgeon's armamentarium.

8/164. Case report of a mass that mimicked an antrochoanal polyp.

    We describe the case of a patient who was originally diagnosed with an antrochoanal polyp. During avulsion of the mass by endoscopic polypectomy, it was discovered that the stalk of the polyp actually arose from the mucosa of the right superior turbinate rather than from the mucosa of the maxillary antrum. A diagnosis of choanal polyp was made.

9/164. Case report of a bleeding nasal polyp during pregnancy.

    We report a case of pregnant woman who had a pyogenic granuloma that had caused chronic epistaxis for 1 week's duration. The lesion was excised and the patient recovered fully.

10/164. Isolated intracranial mucocele.

    Intracranial mucoceles have been previously reported as direct extradural extensions of mucoceles of the paranasal sinuses. We describe a patient with 2 silent mucoceles isolated within the parenchyma of the frontal lobe of the brain. The patient had undergone multiple previous intranasal polypectomy and ethmoidectomy procedures, and the unsuspected mucoceles were discovered on a computed tomographic scan obtained to evaluate recurrent rhinosinusitis symptoms. craniotomy was required for removal of the mucoceles.
