Purpose: To report a choroidal melanoma in a 7-year-old child treated by trans-scleral local resection and adjuvant brachytherapy with a family history of neurofibromatosis type I (NF1) and cutaneous melanoma. Patient and methods: A 7-year-old child was referred for treatment of a choroidal tumor in her left eye with a differential diagnosis of melanoma, neurilemmoma, leiomyoma, and neurofibroma. Trans-scleral local resection and, subsequently, adjuvant brachytherapy were performed. Results: Histopathology and immunohistochemistry of the specimen diagnosed an amelanotic melanoma of spindle cell type, with a moderately high number of mitoses (7/40 HPF). Multiplex ligation-dependent probe amplification (MLPA) analysis showed two copies of chromosome 3, three copies of the short arm of chromosome 6, and two copies of chromosome 8, strongly suggesting a good prognosis. Postoperative ophthalmic evaluation at 6 months showed no visible tumor and flat retina with visual acuity (VA) of 6/60. Conclusions: Trans-scleral local resection with adjuvant brachytherapy in children is possible using the same techniques as for adults. Although the follow-up is short, our patient retained the eye with good vision and our cytogenetic studies allowed us to reassure the mother. © 2010 Springer-Verlag.

Abstract

Purpose: To report a choroidal melanoma in a 7-year-old child treated by trans-scleral local resection and adjuvant brachytherapy with a family history of neurofibromatosis type I (NF1) and cutaneous melanoma. Patient and methods: A 7-year-old child was referred for treatment of a choroidal tumor in her left eye with a differential diagnosis of melanoma, neurilemmoma, leiomyoma, and neurofibroma. Trans-scleral local resection and, subsequently, adjuvant brachytherapy were performed. Results: Histopathology and immunohistochemistry of the specimen diagnosed an amelanotic melanoma of spindle cell type, with a moderately high number of mitoses (7/40 HPF). Multiplex ligation-dependent probe amplification (MLPA) analysis showed two copies of chromosome 3, three copies of the short arm of chromosome 6, and two copies of chromosome 8, strongly suggesting a good prognosis. Postoperative ophthalmic evaluation at 6 months showed no visible tumor and flat retina with visual acuity (VA) of 6/60. Conclusions: Trans-scleral local resection with adjuvant brachytherapy in children is possible using the same techniques as for adults. Although the follow-up is short, our patient retained the eye with good vision and our cytogenetic studies allowed us to reassure the mother. © 2010 Springer-Verlag.
