Abstract
The authors present an unreported case of malignant conjunctival melanoma with metastasis to the right cardiac atrium. A 67-year-old woman with history of conjunctival melanoma of the OS presented with asymptomatic recurrence with new extension to the fornix. Surgical management was planned; however, the patient was admitted to the hospital with symptoms of heart and respiratory failure. She was found to have a large mass in the right atrium. The mass was resected and was found to be metastatic conjunctival melanoma. The patient received chemotherapy and her symptoms have improved. This case highlights the high recurrence rate of conjunctival melanoma and the importance of tumor surveillance.

Abstract
Background/Aims Metastases of malignant melanoma (MM) are rare and associated with poor prognosis. The objective of this study was to analyze the clinical and endoscopic characteristics of gastric metastases of MM by systematically reviewing cases and case series involving patients diagnosed using upper gastrointestinal endoscopy. Methods The PubMed and LILACS databases were searched. Reports containing individual patient data were included. Outcomes such as clinical data, endoscopic findings, treatments, and survival were analyzed.
Results A total of 88 studies with individual data from 113 patients with gastric metastases of MM were included. The primary sites of MM were the skin (62%), eyes (10%), and mucous membranes (6%). Most patients (56%) had multiple metastases in the stomach, located predominantly in the gastric body (approximately 80%). The overall survival rate at 2 years was 4%. There was a significant reduction in the survival of patients with multiple gastric metastases compared to that of patients with single metastasis (hazard ratio, 0.459; 95% confidence interval, 0.235−0.895; p=0.022).
Conclusions Gastric metastases of MM have a poor prognosis, especially in patients with multiple implants in the stomach. Additional studies are needed to verify whether ocular and mucosal melanomas are associated with a higher risk of gastric metastases than that of cutaneous melanomas.

American Joint Committee on Cancer (AJCC) tumor staging system predicts the outcome and metastasis pattern in conjunctival melanoma. Ophthalmology 2022; 129:771-780. [PMID: 35245602 DOI: 10.1016/j.ophtha.2022.02.029] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Revised: 02/21/2022] [Accepted: 02/22/2022] [Indexed: 12/22/2022] Open
Abstract
PURPOSE To assess the predictive value of the tumor staging system in the eighth edition of the American Joint Committee on Cancer Cancer Staging Manual (AJCC 8th-Edition) and histologic features for outcomes and metastasis patterns in conjunctival melanoma (CM). DESIGN Retrospective, single-center cohort study. PARTICIPANTS Eighty-three patients with CM were treated at our center between 2000 and 2021. METHODS We reviewed clinical and histopathological parameters and used Kaplan-Meier survival curves and Cox proportional hazards regression models for risk factor analyses. MAIN OUTCOME MEASURES Time to nodal/distant metastasis, disease-specific survival, metastatic pattern, and metastatic site. RESULTS At presentation, five patients (6%) had cT1 disease, 34 (41%) had cT2 disease, and 44 (53%) had cT3 disease. Four (5%) patients had nodal metastasis (N1), and none had distant metastasis (M1). During follow-up, 12 (14%) developed nodal metastasis, 29 (35%) developed distant metastasis, and 26 (31%) died of disease. Brain, liver and lung were common distant metastasis sites. Higher cT category was associated with increased risks of distant metastasis (p<0.001) and disease-specific death (p=0.002). The separate analysis of primary and recurrent tumors at presentation showed that the patients with cT3 tumors took a much higher risk of distant metastasis than those with cT2 tumors. Greater tumor thickness, ulceration, and the presence of regression were correlated with distant metastasis. Previously unreported mutations were detected in the tumor suppressor genes: FAT4 and SYK. Among the 29 patients who developed distant metastasis, we analyzed two patterns of metastasis: 11 patients (38%) developed nodal metastasis prior to distant metastasis, and 18 patients (62%) developed distant metastasis without previously known nodal metastasis. The patients with cT3 tumors were more likely to follow the latter metastasis pattern (p=0.02). CONCLUSION CM presented with mostly advanced stages and high rates of distant metastasis in the current Chinese cohort. This study confirmed the prognostic value of the tumor staging system in the AJCC 8th-Edition in Chinese patients. Histologic features, such as tumor thickness and ulceration, should be emphasized when assessing prognosis and guiding the treatment of CM.

Abstract
OBJECTIVE To report the clinical features of 20 patients with malignant melanoma and to evaluate the survival and prognosis of patients with malignant melanoma in Korea. METHODS AND ANALYSIS The medical records of 20 patients with malignant melanoma treated between March 2004 and March 2020 were reviewed retrospectively. The demographic data, clinical characteristics, and outcomes were also reviewed. Outcome measures included local recurrence, metastasis, and tumor-related mortality. Prognostic factors associated with recurrence, metastasis, and survival were analyzed using a Cox proportional hazards model. RESULTS Among the 20 patients with periocular malignant melanoma, 4 (20%) showed local recurrence during follow-up (6.61 ± 6.36 years). The 1-, 5-, and 10-year recurrence rates were 5%, 10.3%, and 24.1%, respectively. 10 (50%) patients developed distant metastasis, mainly involving lung, brain, parotid gland and spine. The 1-, 5-, and 10-year rates of metastasis were 5%, 10.9%, and 35.7%, respectively. Significantly fewer metastases were detected following initial extensive surgical excision (P = 0.04). 8 (40%) patients died of malignant melanoma. The main risk factor for mortality was tumor thickness (HR: 3.88, P < 0.01). Based on Kaplan-Meier survival estimates, the 1-, 5-, and 10-year tumor-related survival rates were 75.8%, 55.6%, and 55.6%, respectively. CONCLUSION Tumor thickness is a significant prognostic factor affecting the survival rate. It is important to reduce the metastatic rate via extensive resection without leaving any residual tumor in the margin during surgery.

Abstract
Conjunctival melanoma (CJM) is a rare but potentially lethal and highly-recurrent cancer of the eye. Similar to cutaneous melanoma (CM), it originates from melanocytes. Unlike CM, however, CJM is relatively poorly characterized from a genomic point of view. To fill this knowledge gap and gain insight into the genomic nature of CJM, we performed whole-exome (WES) or whole-genome sequencing (WGS) of tumor-normal tissue pairs in 14 affected individuals, as well as RNA sequencing in a subset of 11 tumor tissues. Our results show that, similarly to CM, CJM is also characterized by a very high mutation load, composed of approximately 500 somatic mutations in exonic regions. This, as well as the presence of a UV light-induced mutational signature, are clear signs of the role of sunlight in CJM tumorigenesis. In addition, the genomic classification of CM proposed by TCGA seems to be well-applicable to CJM, with the presence of four typical subclasses defined on the basis of the most frequently mutated genes: BRAF, NF1, RAS, and triple wild-type. In line with these results, transcriptomic analyses revealed similarities with CM as well, namely the presence of a transcriptomic subtype enriched for immune genes and a subtype enriched for genes associated with keratins and epithelial functions. Finally, in seven tumors we detected somatic mutations in ACSS3, a possible new candidate oncogene. Transfected conjunctival melanoma cells overexpressing mutant ACSS3 showed higher proliferative activity, supporting the direct involvement of this gene in the tumorigenesis of CJM. Altogether, our results provide the first unbiased and complete genomic and transcriptomic classification of CJM. Conjunctival melanoma is an extremely rare form of cancer of the eye that arises from melanocytes–the cells producing the protective pigment melanin–in the outmost layer of the eye: the conjunctiva. This tissue, similarly to the skin, can also be exposed to UV light radiation from the sun. We investigated the genetic background of this rare form of cancer in samples from fourteen patients, by global DNA and RNA sequencing. Our results showed that conjunctival melanoma is genetically very similar to cutaneous melanoma. More precisely, in tumor DNA we detected signs of damage caused by UV light, as well as mutations in the genes BRAF, NF1 and NRAS/HRAS, previously described to be involved in cutaneous melanoma. Analysis of tumor gene expression also revealed similarities between these two types of cancer, some of which could be used as prognostic factors or as indicators of a patients’ response to therapy. In addition, we identified frequent somatic mutations in ACSS3, a gene not yet associated with either conjunctival or cutaneous melanoma, which represents a potential key player in oncogenesis of conjunctival melanoma.

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.

Abstract
Clinical reports of primary sphenoid sinus melanoma and isolated gastric metastatic melanoma are rare. Thus, to the best of our knowledge, the present study reports the first case of isolated gastric metastasis from a sphenoid sinus melanoma. The aim of the present study was to discuss the clinicopathological and radiographic characteristics, the treatment strategy and the prognosis of sphenoid sinus metastatic malignant melanoma of the stomach. Although almost 60% of patients who succumb to melanoma exhibit gastrointestinal metastases at autopsy, antemortem diagnosis is uncommon; this is predominantly due to gastric metastatic melanoma presenting with non-specific symptoms similar to other common gastrointestinal diseases. Gastrectomy may prolong overall survival and improve the quality of life for gastric metastatic melanoma patients, and the present case emphasizes the importance of palliative surgery in such cases.

Abstract
Conjunctival malignant melanoma is a pigmented lesion of the ocular surface. It is an uncommon but potentially devastating tumor that may invade the local tissues of the eye, spread systemically through lymphatic drainage and hematogenous spread, and recur in spite of treatment. Despite its severity, the rarity of available cases has limited the evidence for diagnosis and management. This review will provide an overview of the epidemiology, presentation, diagnosis, management, and surveillance of conjunctival melanoma, with an emphasis on recent advances in biological therapies to treat this disease.

Abstract
Melanocytes arise from the neural crest and migrate to the epidermis, meninges, uveal tract and ectodermal mucosa. Normal gastric mucosa lacks melanocytes. A 64-year-old woman presented to us with nausea and vomiting. She had a past history of invasive primary mucosal epithelioid malignant melanoma of the hard palate 21 months ago, treated by a wide surgical excision. Gastroscopy revealed multiple punched out ulcers involving the stomach and the first part of duodenum. Immunohistology and clinicopathologic correlation established the diagnosis of metastatic gastric malignant melanoma. To our knowledge, this is the first report in the English literature about gastric metastases arising from primary palatal mucosal melanoma.

Abstract
BACKGROUND To report our experience with sentinel lymph node biopsy for staging patients with conjunctival melanoma. METHODS A prospective review of patients with conjunctival melanoma who underwent sentinel lymph node biopsy at St Bartholomew's Hospital from May 2008 to May 2012. The selection criterion for sentinel node biopsy depended on the tumour thickness (≥2 mm) and location of the conjunctival melanoma. The main outcome measures were the incidence of sentinel lymph node positivity and the procedure-related complications. RESULTS In 4 years, 26 out of 70 patients met the selection criteria for sentinel lymph node biopsy. 4 patients declined and 22 patients consented for the procedure. Technetium-99m failed to identify a sentinel lymph node in four of the 22 patients (18%). Of the remaining 18 patients, two were found to have subclinical micrometastasis in regional lymph nodes. Median follow-up was 20 months (range 6-36 months). No false-negative events were observed. Complications of the procedure included transient blue staining of the epibulbar surface in five patients and transient facial nerve palsy in one patient. CONCLUSIONS Sentinel lymph node biopsy is a safe procedure with minimal complications. It should be considered for the staging of conjunctival melanomas, especially melanomas in non-limbal location or conjunctival melanomas ≥2 mm thick.
