1/192. Early-onset scleral necrosis after iodine I 125 plaque radiotherapy for ciliochoroidal melanoma.

    A 62-year-old man with a large ciliochoroidal melanoma developed early-onset scleral necrosis with tumor extrusion within 1 month of epibulbar iodine I 125 plaque radiotherapy. The eye was enucleated. Pathologic study revealed nonmicrobial scleral necrosis with extrusion of histologically intact and necrotic uveal melanoma cells. The patient has been followed up for 15 months without clinical recurrence. We discuss possible mechanisms to explain the early development of scleral necrosis after plaque therapy in this patient.

2/192. ciliary body melanocytoma with anterior segment pigment dispersion and elevated intraocular pressure.

    PURPOSE: To discuss a case in which melanocytoma of the ciliary body presented with widespread pigment dispersion and elevated intraocular pressure (IOP). methods: A 64-year old woman presented with increased IOP and persistent anterior segment inflammation in her right eye. She had undergone a trabeculectomy for uncontrolled IOP before presentation. Slit-lamp examination, gonioscopy, and ultrasound biomicroscopy revealed a ciliary body mass with extension into the subconjunctiva in addition to widespread pigmentary dispersion in the anterior segment. Enucleation of the right eye was performed for histopathologic evaluation, as a diagnosis of ciliary body melanoma was made on clinical examination. RESULTS: Histopathologic findings were diagnostic of a melanocytoma of the ciliary body with necrosis and focal malignant transformation with extension of melanocytoma cells and melanophages into the subconjunctival space, trabecular meshwork, and anterior chamber angle. CONCLUSION: Melanocytoma of the ciliary body is a rare intraocular tumor that may present with pigment dispersion and secondary elevated IOP. Careful examination of the anterior segment is imperative in such cases.

3/192. Malignant transformation of an optic disk melanocytoma.

    PURPOSE: To report a case of malignant transformation of an optic disk melanocytoma with a second melanocytoma in the ciliary body. methods: Clinical data including visual acuity, visual fields, color fundus photographs, fluorescein angiogram, and ultrasonogram and histopathologic studies of this case were reviewed. RESULTS: The right eye of a 65-year-old white woman was diagnosed with melanocytoma of the optic nerve. Four years later, the tumor became significantly larger. The best-corrected visual acuity declined from 20/40 to counting fingers and the size of the tumor increased fourfold in 2 years. The right globe was enucleated. Histopathologic studies demonstrated moderately pigmented spindle-B malignant melanoma cells adjacent to and within a population of large, polyhedral, heavily pigmented melanocytoma cells that extended to the lamina cribrosa and optic nerve. There was also a deeply pigmented melanocytoma in the ciliary body. CONCLUSION: This is a rare case of malignant melanoma transformed from an optic disk melanocytoma. Periodic follow-up of the patient with optic disk melanocytoma is necessary.

4/192. Ring melanoma--a rare cause of refractory glaucoma.

    BACKGROUND: Ring melanoma of the ciliary body and iris is extremely rare and often has adverse histology. This tumour may cause raised intraocular pressure. methods: A review of four cases of ring melanomas with insidious presentations seen in the ocular oncology service over a 12 month period. RESULTS: All four patients presented with unilateral anterior segment abnormalities and refractory glaucoma. The misdiagnoses of the causes of the glaucoma included angle recession from previous blunt trauma (patient 1); iridocorneal endothelial (ice) syndrome supported by endothelial specular microscopy (patients 2 and 3); and melanocytoma on ciliary body biopsy (patient 4). Two patients were treated by several cyclodiode ciliary body ablation treatments and the other two underwent trabeculectomies and Molteno tubes. Two of the four patients have since died from their disease. CONCLUSION: The ophthalmologist should re-evaluate the diagnosis in patients with anterior segment abnormalities and refractory ipsilateral glaucoma. Endothelial specular microscopy and biopsy of the suspicious lesion may give misleading reassurance. The potential presence of an anterior uveal melanoma must always be considered.

5/192. Multifocal intraocular malignant melanoma: report of two cases and review of the literature.

    PURPOSE: To describe two eyes from two patients with multifocal primary intraocular melanoma. DESIGN: Two case reports. methods: The history and histologic findings in the enucleated eyes of two patients with multifocal intraocular melanoma are described in comparison to previously reported cases. MAIN OUTCOME MEASURES: Pathologic examination of enucleated eyes. RESULTS: One of the two eyes contained mixed cell type melanomas, and one eye contained spindle cell type melanomas. Examination of serial sections showed no continuity between the intraocular melanomas. There were no associated ocular or systemic conditions with the multifocal intraocular melanomas. CONCLUSIONS: Multifocal primary intraocular melanoma is rare. There is no known predisposing factor to this condition.

6/192. Intraocular metastases of cutaneous malignant melanoma: a case report and review of the literature.

    Cutaneous malignant melanoma metastatic to the eye is rare but has been documented. The usual presentation is after the diagnosis of disseminated metastases. A 40-year-old Caucasian man presented with floaters and hazy vision due to ocular metastasis. He developed painful intractable rubeotic glaucoma leading to enucleation. Histopathological examination confirmed anterior segment tumour adherent to the iris that was consistent histopathologically with the primary cutaneous melanoma.

7/192. Intraocular melanoma spread to regional lymph nodes: report of two cases.

    PURPOSE: To report two cases of regional lymphatic spread of primary uveal melanoma. methods: The clinical records of two patients who underwent enucleation for uveal melanoma and later developed regional lymph node metastases were reviewed. One of the two eyes was initially treated with proton beam irradiation. Histologic sections of the enucleated eyes and excised lymph nodes were examined. RESULTS: The melanomas arose in the choroid and ciliary body of the two patients and spread to regional lymph nodes 2 years after enucleation. The choroidal melanoma recurred after irradiation, diffusely infiltrated the uveal tract, and extended into the conjunctiva via an emissary canal. The ciliary body melanoma spread through the trabecular meshwork to the conjunctiva. CONCLUSIONS: Choroidal and ciliary body melanoma may rarely exhibit regional lymph node metastasis. This mode of metastasis may occur after extraocular spread and invasion of conjunctival lymphatics.

8/192. Malignant melanoma of the conjunctiva with intraocular extension.

    Intraocular extension of a malignant melanoma of the conjunctiva is a rare entity. A 75-year-old woman underwent repeated surgery after receiving the diagnosis of a multilocular recurrent malignant melanoma arising from a primary acquired melanosis. Treatment included 2 lamellar sclerokeratectomies and percutaneous radiotherapy. Five years after initial surgery, intraocular extension of the melanoma was observed, and enucleation was performed. Findings from histopathological examination revealed a malignant melanoma occupying part of the ciliary body, the trabecular meshwork, and the iris. Eyes with recurrent malignant melanoma of the conjunctiva should be carefully monitored for intraocular extension. Deep excision of conjunctival melanoma, including lamellar sclerokeratectomy, may abolish the natural barrier against intraocular extension of malignant melanomas of the conjunctiva.

10/192. Uveal melanoma in young patients.

    OBJECTIVE: To study the clinical profile of young patients with uveal melanoma. DESIGN: Retrospective case-control series. SETTING: Tertiary referral center. patients: Data on 63 patients aged 20 years or younger with uveal melanoma were reviewed for clinical profile and association with oculo(dermal) melanocytosis, familial uveal melanoma, dysplastic nevus syndrome, cutaneous melanoma, and other second malignant neoplasms. RESULTS: Of 8000 patients with uveal melanoma, 63 (0.8%) were found in patients who were 20 years of age or younger. The median age at diagnosis was 16 years, and the youngest patient was 3 years old. Sixty-two patients (98%) were white, and uveal melanoma was unilateral in all cases. Seven patients (11%) had oculo(dermal) melanocytosis. Two patients (3%) had dysplastic nevi syndrome, and personal history of cutaneous melanoma was observed in 1 patient (2%). No other second cancers were present in any patient. The 5- and 15-year posttreatment survival estimates were 0.95 (95% confidence interval, 0.87-1.00) and 0.77 (95% confidence interval, 0.52-1.00), respectively. CONCLUSIONS: Uveal melanoma is rare in children or teenagers. It occurs in a heterogeneous group displaying various associations, especially with oculo(dermal) melanocytosis. Oculo(dermal) melanocytosis is 9 times (95% confidence interval, 3.6-22.8) more common in young patients with uveal melanoma than in the general population with uveal melanoma. Young patients with uveal melanoma have short-term (5-year) survival better than that of adults, but the long-term (15-year) survival is similar to that of adults. Arch Ophthalmol. 2000;118:918-923
