Cantu-Soriano G, Sanchez N, Suarez-Reynoso L, Padilla-Rodriguez A. Pediatric conjunctival melanoma: A comprehensive case report and literature review. Am J Ophthalmol Case Rep 2024; 35:102075. [PMID: 38841151 PMCID: PMC11152603 DOI: 10.1016/j.ajoc.2024.102075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 01/30/2024] [Accepted: 04/26/2024] [Indexed: 06/07/2024] Open
Abstract
Purpose This case report aims to present a rare instance of conjunctival melanoma in a 5-year-old patient and contribute to the limited body of knowledge on pediatric conjunctival melanoma. The purpose is to understand the characteristics, diagnosis, and management of this uncommon malignancy in young individuals. Observations The case describes a 5-year-old female with a progressively growing pigmented conjunctival lesion. The lesion was observed to be located on the temporal conjunctiva of the right eye and displayed distinctive features, including feeder vessels. Imaging revealed specific dimensions of the lesion and ruled out deeper invasions. Histopathological examination revealed architectural and cytologic atypia, positive immunohistochemical staining for HMB-45, and a Ki67 proliferation index of 20 %, confirming the diagnosis of conjunctival melanoma. Conclusions Conjunctival melanoma, an uncommon malignancy even more so in pediatric patients, typically presents with pigmented growths and feeder vessels. This case underscores the need for thorough diagnosis and early intervention, as conjunctival melanoma can lead to devastating outcomes. The rarity of such cases limits our understanding of their etiology and progression. This case contributes to the literature on pediatric conjunctival melanoma and reinforces the importance of vigilance in detecting and managing ocular pigmented lesions in children.

Abstract
INTRODUCTION Conjunctival melanoma is extremely rare in children and has low rates of resolution. Definitive histopathological diagnosis based exclusively on microscopic findings is sometimes difficult. Thus, early diagnosis and adequate treatment are essential to improve clinical outcomes. CLINICAL CASE We present the first case in which the fluorescent in situ hybridization (FISH) diagnostic technique was applied to a 10-year-old boy initially suspected of having amelanotic nevi in his right eye. Based on the 65% of tumor cells with 11q13 (CCND1) copy number gain and 33% with 6p25 (RREB1) gain as measured by the FISH analysis, and on supporting histopathological findings, the diagnosis of conjunctival melanoma could be made. Following a larger re-excision, adjuvant therapy with Mitomycin C (MMC), cryotherapy and an amniotic membrane graft, the patient has remained disease-free during 9 years of long-term follow-up. CASE DISCUSSION Every ophthalmologist should remember to consider and not forget the possibility of using FISH analyses during the differential diagnosis of any suspicious conjunctival lesions. Genetic techniques, such as FISH, have led to great advances in the classification of ambiguous lesions. Evidence-based guidelines for diagnosing conjunctival melanoma in the pediatric population are needed to determine the most appropriate strategy for this age group.

Abstract
Conjunctival melanoma (CjM) is a rare, primary cancer of the ocular region. Genetic and epigenetic characteristics of conjunctival melanoma have not been completely elucidated yet. Conjunctival melanoma presents similarities with cutaneous melanoma, with substantial differences in the biological behavior. We reviewed the genetic and epigenetic insights of CjM involved in invasion and metastatic spread. CjM is commonly characterized by mutations of v-raf murine sarcoma viral oncogene homolog B1 (BRAF), neurofibromin 1 (NF1) and telomerase reverse transcriptase (TERT), high expression of mammalian target of rapamycin (mTOR) and heat shock protein 90 (HSP90), frequent phosphatase and tensin homolog (PTEN) loss and upregulation of specific miRNAs. These features should identify CjM as a distinct subset of melanoma with its own profile, which is more similar to cutaneous melanoma than mucosal melanoma and remarkably different from uveal melanoma.

Abstract
OBJECTIVE The purpose of the present study is to describe the clinical characteristics and outcomes of patients diagnosed and treated for conjunctival melanoma in the Ocular Oncology Unit of the University Hospital Clinic of Valladolid. METHODS A retrospective observational case series study was conducted on patients diagnosed with conjunctival melanoma in the Ocular Oncology Unit of University Hospital Clinic of Valladolid, from January 1992 to December 2017. Demographic information and tumour features were recorded in a Microsoft Access database. RESULTS Among a total of 462 consecutive patients, the tumour was classified as melanocytic in 252 cases (54.5%), with 27 patients having the pathological diagnosis of conjunctival melanoma. The mean age at diagnosis was 59.2years (16-88), and there were 41% males and 59% females, with a mean follow-up of 6.1±6.8years. As regards the origin of conjunctival melanoma, 16 cases (59%) arose from primary acquired melanosis, 26% from nevus, and 15% developed de novo. The treatment performed was incisional or excisional biopsy in all patients, local adjuvant chemotherapy in 15 cases (56%) and brachytherapy in 5 patients (18%). The median survival was 18years and the probability of survival at 5 and 10years was 89% and 69%, respectively. CONCLUSIONS Conjunctival melanoma is a rare disease, usually undervalued by the patient as well as being underdiagnosed, leading to insufficient and delayed treatment. Early diagnosis and treatment are essential to prevent recurrences and systemic extension, as well as to preserve vision and life.

Abstract
Background Conjunctival melanoma is rare in adults and rarer in children. We systematically reviewed the presentation, diagnostic and management strategies as well as outcomes for conjunctival melanoma in children and adolescents. Methods The following databases were searched: Medline, Embase, Web of Science and Scopus for cases of conjunctival melanoma occurring in children and adolescents < 18 years of age. Results Seventeen studies with 32 patients (18 males) were identified. The median age at presentation was 11 years (range 4-18 years). Most patients were white. Most patients presented with a conjunctival mass or naevus with a recent history of growth or change. Excision biopsy provided diagnosis and management for all cases. Adjuvant chemotherapy and radiotherapy were also used. One patient had metastatic disease at diagnosis and 3 developed metastatic disease (range 1-10 months). Two patients died from disease and one was alive with metastatic disease. Two patients had disease recurrence. Outcomes were observed to be better where diagnosis was made earlier and "no-touch" excision biopsy was performed in an appropriate specialist setting. Conclusions Conjunctival melanoma occurs rarely in children and adolescents. Surgery is the mainstay of management. The prognosis is guarded in metastatic disease due to the small sample size and limited follow-up.

Abstract
We present a rare case of conjunctival melanoma in a 9-year-old girl who presented with a conjunctival lesion of the left eye, growth of which was documented by patient photographs. Examination showed a raised pigmented lesion at the temporal limbus, with fine surrounding vessels. Enhanced depth imaging-optical coherence tomography showed no invasion into the sclera. The patient underwent excisional biopsy, and histopathology revealed conjunctival melanoma arising from a nevus with malignant cells that stained positively with markers HMB-45 and Ki-67. Systemic workup was negative for metastatic disease. Conjunctival nevi are the most common melanocytic conjunctival lesions in children and generally demonstrate physiologic growth during adolescence. Thus, there may be a greater risk of misdiagnosis of conjunctival melanoma in a child.

Abstract
Malignant melanoma of the conjunctiva is a rare but serious condition. Over the last several years, there have been important advances in the classification, diagnosis, and treatment of this condition. Recent cytogenetic and immunohistochemical studies are increasing understanding of its tumorigenesis. Diagnosis, although still made via histopathology, has been aided with imaging techniques such as ultrasound biomicroscopy and anterior segment optical coherence tomography. Primary treatment consists of surgical excision. But adjuvant treatments with cryotherapy, topical chemotherapy, and radiation therapy have shown increased success. Sentinel lymph node biopsy has shown early promise of detecting micro-metastasis. Long term follow-up of patients with conjunctival melanoma with systemic surveillance is necessary to detect recurrences and metastases.
