摘要:

A total of 24 patients (12 men and 12 women) with squamous cell carcinoma of the eyelid were identified from pathology records at Wills Eye Hospital from 1978 through 1987. Squamous cell carcinoma accounted for 24 of 648 (3.7%) malignant eyelid lesions submitted during the 10-year study period. The median age of patients at the time of diagnosis was 72 years (range, 55 to 96 years). Initial therapy of all tumors involved surgical excision. Four patients developed clinical recurrence of squamous cell carcinoma in a median of 7.5 months after surgery. There were no tumor recurrences when frozen section techniques were applied during the initial surgical excision. The data suggest that the risk of persistence or recurrence of tumor was increased for patients who delayed seeking medical care after the lesion was first noticed and when frozen section control was not used during surgery. None of the patients were known to have developed metas-tases, and there were no tumor-related deaths.

摘要:

A 15-year-old girl presented with a left lower eyelid tumor consistent with a nonresolving chalazion. The specimen was biopsied. Histopathologic examination revealed eosinophilic granuloma, an entity that rarely presents on the eyelid. The histopathologic features of eosinophilic granuloma—a member of the histiocytosis X group of diseases—are reviewed. Our patient responded well to incisional biopsy and has required no additional treatment.

摘要:

Mucoepidermoid carcinoma of the conjunctiva (MECa) is a rare neoplasm. It resembles squamous cell carcinoma (SCCa), clinically and histologically. Nevertheless, it is characterized by a high degree of local aggressiveness. We reviewed all cases of MECa reported in the English literature for epidemiological data, characteristics of the tumor, treatment, and outcome. We found that MECa, reported predominantly in aging males (median age 71 years), arises in the limbal and perilimbal areas. Simple excision is followed by rapid recurrence, and most tumors will require enucleation or exenteration for local control. Histological stains directed to the production of mucin are essential for the diagnosis. The recommended treatment is wide local excision. Enucleation or exenteration is recommended for tumors invading the globe or orbit.

摘要:

This is a clinicopathologic study of 115 lacrimal sac neoplasms in adults (mean 52 years). The most common presenting signs and symptoms were epiphora (53%), recurrent dacryocystitis (38%), and/or lacrimal sac mass (36%). The tumors were divided into epithelial (82 cases) and non-epithelial (33 cases) neoplasms. Benign epithelial tumors included squamous and transitional cell papillomas (32), oncocytomas (4), and benign mixed tumors (2). The malignant epithelial neoplasms included squamous cell carcinoma (22), transitional cell carcinoma (5), adenocarcinoma (4), mucoepidermoid (3), adenoid cystic (3), and poorly differentiated carcinoma (1). The nonepithelial tumors consisted of fibrous histiocytoma (13), lymphoid lesions (10), malignant melanoma (6), hemangiopericytoma (1), lipoma (1), granulocytic sarcoma (1), and neurofibroma (1). Review of the literature, including our own series, discloses a 55% malignancy rate for tumors originating in the lacrimal sac. Malignant epithelial neoplasms, especially invasive transitional cell carcinoma, often recur locally and can metastasize and be fatal. Epithelial malignancies tend to grow along the epithelium of the lacrimal drainage system, and thus cure is dependent on a wide surgical excision of the tumor and of the entire lacrimal drainage system (canaliculi, sac, and nasolacrimal duct) combined with a lateral rhinostomy and radiation therapy.

摘要:

A survey was mailed to members of The American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) concerning the diagnosis and management of patients with epiphora. Specifically, the respondent was asked about his or her work-up and management of an older patient with epiphora whose nasolacrimal system was patent on irrigation. Some pertinent findings were that 48 respondents did not choose the Jones test as one of the diagnostic procedures they employ. A small percentage of respondents do only a Jones test in their evaluation and believe that a dacryocystorhinostomy (DCR) is indicated with a negative Jones test. Technetium scan and dacryocystogram are used by only 13 and 10% of respondents, respectively. Forty-one percent of respondents would treat a pump “functional” block with DCR; 25% would use either Silastic tubing, lid tightening, or a combination of both. Most respondents believed that the success rate of Silastic tubing was fair, at best.

摘要:

Maintaining good wound closure in canalicular lacerations is difficult because of the horizontal tension exerted by the orbicularis muscle on the wound. A method of placing a deep medial canthal traction suture through the medial orbital periosteum to aid in maintaining good wound approximation is presented.

摘要:

Botulinum toxin has recently been used as a nonsurgical treatment for blepharospasm and other facial dyskinesias. This report describes four patients between the ages of 32 and 37 years who failed to respond to botulinum injections for severe blepharospasm. Other than age, no other features could be identified in these patients that would differentiate this group. Particularly early age of onset for essential blepharospasm might be an indicator of failure to respond to the injections.

摘要:

A custom-designed, titanium medial canthal tendon screw (MCTS) was used successfully to correct telecanthus in three patients—two with blepharophimosis syndrome and one with congenital telecanthus. This device avoids the need for complicated transnasal wiring. Precise placement of the screw into the bone at the anterior lacrimal crest may be accomplished through a small skin incision. A through-and-through transverse hole in the screw just below its head allows passage of sutures and wires for internal fixation of the medial canthal tissues as well as for external fixation by a silicone stent. Correction of telecanthus with the MCTS is simpler and apparently a safer procedure than traditional transnasal wiring and, furthermore, may be easily combined with any soft tissue repair.
