 Purpose:Corneal tumors are rare in clinical practice. There was a paucity of data on the incidence of various corneal tumors, their clinical and pathological features and surgical management, especially on large patient samples.  Methods:The medical records of 39 patients with corneal tumors referred to Zhongshan Ophthalmic Center, Sun Yat-sen University, China from Jan 1,1996 to Dec 31,2002 were reviewed retrospectively. Results: Of the 39 cases with corneal tumors, 31 were males and 8 were females. The right eye was affected in 24 cases and the left one in 15 cases. The mean age at diagnosis was 45.7 years, ranged from 3 to 88 years. Squamous cell carcinoma was the most common tumor in the cornea (18 cases, 46.15%), followed by pigmented naevus (12 cases,30.77 %), papillary epithelioma (3 cases, 7.69%), melanoma (1 case, 2.56%), oncosis hyperplasia(1 case, 2.56%), inverting papilloma (1 case, 2.56%), primary acquired melanosis(1 case, 2.56%),amyloid degeneration(1 case, 2.56%),inflammatory pseudotumor(1 case, 2.56%). They arose most commonly in the limbal region. All tumors were unilaterally involved. Squamous cell carcinoma of the cornea usually appears as a whitish, rough, irregular lesion or a telangiectatic, gelatinous epibulbar mass. Nevus in the cornea generally becomes clinically apparent in the first or second decade of life and the lesion may enlarge or more deeply pigmented afterwards. The corneal tumors were completely excised microsurgically in 22 cases. Six cases were treated with surgical resection combined with amniotic membrane graft. Three cases with surgical excision plus transfer of conjunctival flap. Two cases with surgical excision plus lamellar keratoplasty. Two cases with surgical excision plus cryosurgery. Two cases with orbital exenteration. One case with enuleation. One case with incision biopsy and observation. Conclusion: Squamous cell carcinoma and nevus, the most common corneal tumors, accounted for 76.92% of all cases. The therapeutic outcomes depended upon early pathologic diagnosis and early surgical management.  相似文献

Brown cornea     
Background A brown cornea is relatively rare. We report a case of progressive brown corneal pigmentation in a patient with a primary acquired melanosis of the conjunctiva. Later the patient developed an iris melanoma. Methods Case report with clinico-pathological correlation and discussion of possible mechanisms of particle clearance of the cornea. Results A 36-year-old female developed a corneal stromal pigmentation adjacent to a pigmented conjunctival lesion of the left eye. The corneal pigmentation had progressed through 8 years. The conjunctival lesion was surgically removed, and proved histopathologically to be a compound nevus with slight atypia and an acquired melanosis. Despite surgery the corneal pigmentation increased, and visual acuity dropped in the diseased eye. A perforating keratoplasty was performed, and two small pigmented iris nodules were now noted. Three years after grafting, growth of the two iris tumours was obvious. In addition, pigmentation of the trabecular meshwork and large, pigmented endothelial precipitates were observed. The corneal pigmentation also increased. The eye was enucleated. Histopathologic evaluation demonstrated a marked accumulation of melanophages on the endothelium of the graft. The host cornea contained pigmented cells in the mid-stroma. The iris contained two melanomas. Conclusions The brown pigmentation of the cornea was due to pigment granules from the iris tumours liberated to the anterior chamber. The pigment was transported into the cornea through the endothelium and accumulated in melanophages between corneal lamellas. The pigment subsequently cleared via the corneal limbus in a process resembling clearance of corneal haemochromatosis. No financial relationships with organisations or firms exist for any of the authors. All data are original and are in full control of the authors. The authors agree that Graefe’s Archive for Clinical and Experimental Ophthalmology may review primary data on request.  相似文献

Corneally displaced malignant conjunctival melanomas   总被引:2,自引:0,他引:2  
PURPOSE: To characterize and classify malignant conjunctival melanomas with exclusively corneal invasive growth. DESIGN: Population-based, nationwide retrospective cross-sectional study. PARTICIPANTS: Patients with primary malignant conjunctival melanoma diagnosed between 1967 and 2000 in Finland. METHODS: On the basis of all available clinical and histopathologic data of tumors diagnosed during the study period, malignant conjunctival melanomas that first demonstrated invasive growth on the cornea without evidence of conjunctival tumors other than primary acquired melanosis were identified, their prevalence calculated, and their characteristics reviewed. On the basis of these cases and literature data, a classification for "corneal melanoma" was developed. MAIN OUTCOME MEASURES: Frequency and type of corneal involvement, recurrence, and survival. RESULTS: Patients with exclusively corneal invasive tumor accounted for 5% (95% confidence interval, 1-12) of 85 consecutive primary conjunctival melanomas. Two were separated from the limbus by clear cornea (type I), and two paralleled but did not invade the limbal conjunctiva (type II). Two were associated with clear evidence of primary acquired melanosis. None of the tumors recurred after local excision, and no metastases were observed during a median follow-up of 2 years 5 months (range, 1 year 8 months-7 years 10 months). CONCLUSIONS: Primary malignant conjunctival melanomas can grow on the cornea without conjunctival involvement other than acquired melanosis. They are easily removed and do not cause lymphatic metastases. The term "corneally displaced malignant conjunctival melanoma" would best describe their supposed conjunctival origin and actual corneal location.  相似文献

This article reviews literature regarding tumors and tumor-like lesions of the conjunctiva and cornea as published in 1995. Causative and prognostic factors, as well as treatment options, are discussed. Ocular surface squamous neoplasia has been suggested as an "umbrella" term for dysplastic and carcinomatous lesions of the cornea and conjunctiva. Squamous cell carcinoma shows a higher incidence in patients with AIDS. A high prevalence (36%) of primary acquired melanosis is reported in one article, and the need for biopsy of all these lesions is questioned. Reviews of conjunctival myxoma, corneal pyogenic granuloma, and limbal juvenile xanthogranuloma are also included. The pathogenesis and newer treatment options for pterygia are discussed. Simple excision or resection of the pterygium followed by conjunctival autografting or intraoperative or postoperative mitomycin C application seems to be equally effective in reducing the rate of recurrence.  相似文献

An 81-year-old woman with a raised pigmented nodule over her left cornea for 7 months duration was examined. Dark conjunctival pigmentation was observed in the upper bulbar fornix conjunctiva. She had previously undergone primary surgical excision of a malignant conjunctival melanoma four years earlier. The tumor separated easily from the corneal surface, but remained slightly attached to the corneoscleral surface. A corneoscleral lamellar dissection of 3 mm in width and 2 mm in depth as well as a corneoscleral lamellar keratoplasty for the reconstruction of the corneoscleral defect were performed. The wide upper bulbar and fornix conjunctiva were excised, and an amniotic membrane transplantation was performed. Biopsy revealed an invasive melanoma with a depth of 1 mm. Left, right, and inferior tumor margins of the corneoscleral lesion and the pigmentary lesion in the conjunctiva were free of the tumor. After surgery, 0.04% mitomycin was administered topically 4 times daily for 4 weeks. There was no recurrence 2 years after surgery, and systemic evaluation revealed no metastasis.  相似文献

PURPOSE: To study the surgical outcomes and postoperative corneal topographies in 5 patients who had eccentric, biconvex penetrating keratoplasty (PKP) for peripheral corneal disorders whose extent did not allow the use of round grafts without involving the center of the cornea. SETTING: 1st Department of Ophthalmology, Semmelweis University, Medical School, Budapest, Hungary. METHODS: Eccentric, biconvex PKP that spared the optical axis of the cornea was performed in 5 eyes. Indications for surgery were perforated peripheral ulcerative keratitis (n = 3), extensive infiltrated peripheral ulcerative keratitis with impending perforation (n = 1), and ulcerated corneal degeneration caused by an intracameral foreign body for 9 years (n = 1). Computer-assisted corneal topography was performed postoperatively. The follow-up ranged from 8 to 27 months. RESULTS: All grafts were tectonically effective. Postoperative corneal topography showed normal central corneal regularity in 4 cases (1 case, normal pattern with surface regularity index [SRI] and surface asymmetry index [SAI] within the normal range; 3 cases, normal surface regularity within the central area of the cornea but moderate or high central corneal asymmetry). One eye had irregular astigmatism with a high SRI and SAI. In the first 4 cases, the best spectacle-corrected visual acuity was 0.8 (20/25) or better. CONCLUSIONS: The results show that eccentric, biconvex PKP sparing the central cornea may be an option in some eyes with perforated peripheral corneal disorders. Postoperative visual acuity may be good as the procedure may result in a regular central anterior corneal surface.  相似文献

The authors report a case of limbal papilloma with extensive corneal involvement. The limbal lesion was excised completely, leaving a clear corneal bed. Histopathologically, the lesion was found to be a limbal papilloma. Massive superficial involvement of the cornea by papilloma is rare. Simple excision is effective in treating the condition with restoration of vision and cosmesis.  相似文献
