1/104. 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.

2/104. 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.

3/104. 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.

4/104. 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.

5/104. 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.

6/104. 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.

7/104. 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.

8/104. 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.

9/104. Allgrove syndrome in adulthood.

    A 35-year-old man with a past history of achalasia developed progressive spastic tetraparesis, distal limb atrophy, dysarthria, and dysphagia. A clinical diagnosis of amyotrophic lateral sclerosis (ALS) was considered before neurophysiological investigation, which disclosed a polyneuropathy and a prolonged central conduction time. One year later, the patient developed dysautonomic symptoms. Following confirmation of adrenal insufficiency, a diagnosis of Allgrove syndrome was made. This is a rare case, and we emphasize its clinical similarity with ALS.

10/104. Lacrimal gland ductal cyst abscess.

    PURPOSE: To describe a case of lacrimal gland ductal cyst complicated by secondary infection. methods: Case report. RESULTS: A 51-year-old woman presented acutely with an enlarging, painful mass in the superotemporal fornix. Clinical examination, echography, and surgical evaluation revealed a lacrimal gland ductal cyst with abscess formation. The lacrimal gland cyst was treated with oral antibiotics in combination with incision, drainage, and marsupialization. CONCLUSIONS: Lacrimal gland ductal cysts are rare but must be considered in the differential diagnosis of lacrimal gland and upper eyelid mass lesions. Typically, lacrimal gland ductal cysts develop after chronic inflammation, infection, or trauma. We describe a patient who presented acutely with a lacrimal gland ductal cyst associated with a rare complication of abscess formation.
