1/128. Nasolacrimal tuberculosis in a patient with conjunctivodacryocystorhinostomy.PURPOSE: To present an unusual case of nasolacrimal tuberculosis that was diagnosed with polymerase chain reaction (PCR) and to discuss the role of PCR as a diagnostic aid. methods: Case presentation with diagnostic modalities including PCR, cytopathologic, and histopathologic examinations with special stains. RESULTS: A 40-year-old woman with bilateral lacrimal drainage system obstruction underwent a right dacryocystorhinostomy with stents and left conjunctivodacryocystorhinostomy with Jones bypass tube. Although the findings of direct and endoscopic examinations of the nasal cavity were within normal limits, the tissue removed during surgery from the middle turbinate revealed caseating granulomatous lesions on histopathologic examination. Acid-fast organisms were demonstrated in postoperative nasal washings, and mycobacterium tuberculosis infection was confirmed with PCR. CONCLUSION: Primary tuberculosis of the nasolacrimal mucosa is rare, and its occurrence without any symptoms, as in this patient, is even less frequent. The most interesting aspect of this case was the identification of the M. tuberculosis dna in the mucosa of anterior turbinate and fibrous tissue within the previous surgical site. Histopathologically, the presence of caseating granulomas was seen only in the nasal mucosa, indicating that PCR may be of use in identifying the causative organism even in the absence of typical histopathologic features.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
2/128. Ductal cysts of the accessory lacrimal glands: CT findings.Benign ductal cysts of the accessory lacrimal glands are uncommon lesions of the orbit, arising from the glands of Wolfring and Krause. We report two patients with histopathologically proved cysts in whom CT scans revealed well-circumscribed extraconal cystic lesions adjacent to the globe, involving both eyelids. Radiologists should be aware of these rare lesions so as to include them in the differential diagnosis of orbital cysts.- - - - - - - - - - ranking = 1.9546889174761keywords = duct (Clic here for more details about this article) |
3/128. Lacrimal canaliculitis.Lacrimal canaliculitis is an infection of the lacrimal duct system. The classic features of lacrimal canaliculitis are mild to severe swelling of the canaliculus, mucopurulent discharge from the punctum, and a red, pouting punctum. Canaliculotomy with systemic or topical antibiotics is the most appropriate treatment for this disorder.- - - - - - - - - - ranking = 1.9546889174761keywords = duct (Clic here for more details about this article) |
4/128. Management and complications of congenital dacryocele with concurrent intranasal mucocele.INTRODUCTION: The association of dacryocele and intranasal mucocele has been previously reported. Its incidence and optimal treatment are unknown. patients and methods: A retrospective review of 22 patients with 30 dacryoceles was performed to determine the mean age at presentation, sex distribution, and prevalence of associated intranasal mucocele, associated dacryocystitis, and respiratory distress. The components of the examination, ancillary tests, treatment modalities, and treatment outcomes were then summarized. RESULTS: Unilateral dacryoceles were seen in 16 (73%) of the infants, and bilateral dacryoceles were seen in 6 (27%) of the infants. Four (25%) of the 16 patients who initially had unilateral dacryoceles later developed bilateral dacryoceles. dacryocystitis, preseptal cellulitis, or both were present on presentation or developed in 18 (60%) of 30 dacryoceles. Nasal endoscopy was performed on 13 (59%) of 22 patients. Nasal examination with nasal speculum and headlight was performed on 7 patients (32%). A concurrent intranasal mucocele was diagnosed in 23 (77%) of 30 dacryoceles. Respiratory distress arose in 5 (71%) of 7 patients with bilateral intranasal mucoceles and in 2 (22%) of 9 patients with a unilateral intranasal mucocele. Thirty-four procedures were performed. Seven dacryoceles (21%) were treated with nasolacrimal duct probing under topical anesthesia. Another one (3%) was treated with needle aspiration with later definitive therapy. All other procedures were managed under general anesthesia. These included 2 nasolacrimal duct probings (6%), 2 probings with silicone tube placement (6%), 10 probings with intranasal mucocele marsupialization and silicone tube placement (29%), and 12 probings with marsupialization alone (35%). Two (29%) of the 7 probings performed under topical anesthesia failed, whereas all other procedures were successful. One dacryocele spontaneously resolved. CONCLUSIONS: Congenital dacryoceles are commonly associated with intranasal mucoceles, dacryocystitis, and preseptal cellulitis. Respiratory distress is common in bilateral cases. Bilateral nasolacrimal duct probing should be considered in unilateral cases because of the high incidence of occult contralateral involvement.- - - - - - - - - - ranking = 5.8640667524284keywords = duct (Clic here for more details about this article) |
5/128. Mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion.PURPOSE: To report a case of mucoepidermoid carcinoma of an accessory lacrimal gland with orbital invasion. methods: The clinical history and pathologic findings of a patient with a left upper eyelid lesion were reviewed. RESULTS: The patient was evaluated and found to have an epithelial tumor arising in an accessory lacrimal gland. Special stains showed mucin production by individual tumor cells. The tumor was classified as mucoepidermoid carcinoma. CONCLUSIONS: Mucoepidermoid carcinoma may arise in accessory lacrimal glands and invade the orbit.- - - - - - - - - - ranking = 1.9546889174761keywords = duct (Clic here for more details about this article) |
6/128. Recurrent lacrimal sac papilloma: case report.Tumors of the lacrimal sac are rare. Benign papillomas comprise approximately 40% of all neoplasms of the lacrimal drainage system. They often present insidiously with symptoms of dacryostenosis or dacryocystitis. Recurrent bouts of dacryocystitis and nasolacrimal duct obstruction were reported in a 35-year-old man over a period of 13 years. A medial canthal mass was noted in the 6th year after the onset of symptoms. A tumor was discovered incidentally during surgical intervention for presumed dacryostenosis. Surgical removal of the tumor and dacryocystorhinostomy were performed. The histopathologic report turned out to be benign papiloma. Local recurrences occurred during the follow-up period. In addition to surgical excision, we applied cryotherapy and CO2 laser to prevent further recurrence. This case we presented the characteristic recurrence of lacrimal sac papilloma and implied the possibility of tumor occurrence in a patient with recurrent dacryocystitis. We must bear in mind that a recurrent dacryocystitis may be a presentation of a lacrimal sac tumor, because early diagnosis and aggressive treatment can prevent recurrence and result in a cure.- - - - - - - - - - ranking = 259.74170645538keywords = duct obstruction, duct, obstruction (Clic here for more details about this article) |
7/128. Atypical presentation of a dacryolith.PURPOSE: To describe the clinical features and management of a patient with an extralacrimal dacryolith. methods: Case report. RESULTS: A 43-year-old woman remarked at a routine eye examination that a small, firm mass located for several years on the right side of her nose had recently become slightly larger. The mass had remained firm and nontender during this enlargement. She explicitly denied having any past or current lacrimal outflow problems. Surgical excision disclosed a mass external to the lacrimal sac and duct, adherent to its lateral wall. The histopathologic features were consistent with a dacryolith surrounded by a chronic inflammatory reaction and no epithelial lining. CONCLUSION: We presume that the dacryolith must have formed within the lacrimal sac and then migrated laterally into the surrounding soft tissue.- - - - - - - - - - ranking = 1.9546889174761keywords = duct (Clic here for more details about this article) |
8/128. Radical resection for naso-lacrimal duct tumour.Naso-lacrimal duct tumours are uncommon and present with epiphora and swelling. Since the naso-lacrimal duct is embedded in bone for the majority of its anatomical length, the late presentation of proptosis is due to orbital extension of the tumour. Radical surgical treatment is necessary to establish clear margins and facilitate reconstruction.- - - - - - - - - - ranking = 11.728133504857keywords = duct (Clic here for more details about this article) |
9/128. granular cell tumor of the lacrimal sac and nasolacrimal duct: no invasive behavior with incomplete resection.OBJECTIVE: Granular cell tumors are rare tumors of the periorbital region, and we present the second such case in the lacrimal sac. The natural history and clinical behavior of these tumors is reviewed. DESIGN: Case report. methods: The clinical presentation, workup, surgical approach, and pathology of a case of granular cell tumor of the lacrimal sac are presented. RESULTS: There has been no recurrence of the lacrimal sac tumor with incomplete resection. CONCLUSIONS: This case history further adds to the understanding of the biologic behavior of granular cell tumors in the periorbital region.- - - - - - - - - - ranking = 7.8187556699045keywords = duct (Clic here for more details about this article) |
10/128. Three different types of congenital lacrimal sac fistulas.Three different symptoms in 4 patients with congenital lacrimal sac fistulas are presented. The first symptom was epiphora since birth, the second symptom was infection of the lower eyelid, and the third symptom was tearing from the eye in a 76-year-old patient. This patient had nasolacrimal obstruction at the canal level and no symptoms of congenital lacrimal sac fistula. She had undergone excision, including dacryocystorhinostomy. Three of the 4 patients underwent excision of the fistulous tract. The fistula originated from the lacrimal sac in all patients. Symptomatic congenital lacrimal sac fistulas can be treated successfully with excision alone or with excision and dacryocystorhinostomy in cases of nasolacrimal obstruction.- - - - - - - - - - ranking = 2keywords = obstruction (Clic here for more details about this article) |
