BACKGROUND: We sought to update our prior report of findings on sentinel lymph node biopsy (SLNB) and predictors of a positive SLN in patients with conjunctival or eyelid melanoma. METHODS: We reviewed the records of all patients with ocular adnexal melanoma who underwent SLNB at one institution during 2000-2015. We determined rates of positive and false-negative findings on SLNB, primary tumour features correlated with positive findings and rate of nodal recurrence (false-negative event) after negative findings...

Objective: We aimed to identify and describe the clinical and histopathologic characteristics of conjunctival neoplasms. Methods: Retrospective case series study. We collected and analyzed the clinical and histopathologic data of the conjunctival neoplastic specimens including the age, gender, and histopathologic diagnosis of all patients obtained from Beijing Tongren Eye Center between October 2003 and October 2015. All the pathology diagnosis results were divided into two categories which were benign and malignant tumors, according to Shields histopathological classification methods and the pathology diagnosis results in our department...

Programmed cell death 1 (PD-1) inhibitors are members of a new class of drugs known as immune checkpoint inhibitors and have proven efficacy in the treatment of metastatic melanoma. Herein, the authors report the use of nivolumab and pembrolizumab, 2 recently Food and Drug Administration-approved PD-1 inhibitors, in 3 patients: 1 with metastatic conjunctival melanoma and 2 with metastatic cutaneous melanoma and orbital involvement. The patients' metastatic disease responded well to drug treatment. As of this writing, 2 patients have completed therapy and remain disease free at least 1 year after treatment completion; the other patient is still receiving treatment, and his orbital disease is responding...

BACKGROUND: Melanocytic nevus is a rare occurrence in the tarsal conjunctiva and only 7 well-described cases have been reported previously in the English literature. CASE REPORT: The medical records of 4 patients with tarsal conjunctival melanocytic nevus were reviewed, together with the relevant literature. All patients (3 women and 1 man; age range: 17 - 40 years) had been referred with a suspicion of melanoma. There was one tarsal nevus in the lower eyelid in 3 patients and 2 nevi in the upper eyelid in 1 patient...

PURPOSE: Conjunctival melanoma (CM) is a rare disease associated with considerable mortality. As opposed to cutaneous melanoma, the epigenetic mechanisms involved in the development of CM and other mucosal melanomas (MMs) are unclear. The purpose of this study was to identify tumor-specific and prognostic microRNA (miRNA) in CM and to compare the miRNA profile with that of MM. METHODS: Using microarray analysis (Affymetrix) we determined the miRNA expression profile in 40 CMs compared with 7 normal conjunctival samples...

BACKGROUND: Conjunctival malignant melanoma (CMM) is a rare malignancy and in the advanced setting there is no effective treatment. In contrast, half of cutaneous melanomas have BRAF mutations and treatment with BRAF inhibitors is established for patients with disseminated disease. The most common form of ocular melanoma, uveal melanoma, lacks these mutations, however, their presence has been reported for CMM. CASE PRESENTATION: We used the BRAF inhibitor vemurafenib to treat a 53 year-old female suffering from a BRAF(V600E) mutated metastatic CMM...

This report describes a patient with choroidal malignant melanoma presenting as orbital cellulitis without extraocular tumor extension. It is an interventional case report with histopathologic correlation. A 68-year-old male presented with a 3-day history of painful hyperemia and swelling in the right eye. The examination showed edematous eyelids, mechanical ptosis and chemosis with conjunctival injection. B-scan ultrasonography showed a mass with medium level echogenicity that filled the vitreous cavity. Magnetic resonance imaging showed a solid choroidal mass with hemorrhagic and inflammatory changes with no obvious extraocular extension...

PURPOSE: Conjunctival melanoma (CM) is a rare but lethal form of cancer. Similar to cutaneous melanoma, CM frequently carries activating mutations in BRAF and NRAS. We studied whether CM as well as conjunctival benign and premalignant melanocytic lesions express targets in the mitogen-activated protein kinase (MAPK) and AKT pathways, and whether specific inhibitors can suppress CM growth in vitro. METHODS: 131 conjunctival lesions obtained from 129 patients were collected...

UNLABELLED: Conjunctival nevi are the most common tumors of this location. They are usually unilateral, although bilateral cases may also be met. As to clinical presentation, all nevi are divided into: stationary or progressive nevi, blue nevi, and primary acquired melanosis. Color changes are acceptable, if they occur during pregnancy or puberty. However, if postpubertal, such changes should be considered alarming, as to possible malignization. Histopathologically, nevi are composed of melanocyte clusters in the skin stroma next to the basal layer of the epidermis...

PurposePhaeohyphomycosis are melanin-containing fungi that rarely infect the eye. We describe three cases of ocular infection with some unusual clinical features.MethodsSeries of three case reports describing three different presentations of phaeohyphomycosis of the eye, their histopathology, and management.ResultsCase 1 mimicked an inflamed conjunctival naevus and was excised on this basis, revealing a conjunctival retention cyst containing pigmented fungal hyphae. Case 2 showed a wooden foreign body incidentally associated with pigmented fungal hyphae, which required treatment with topical antifungal therapy...

PURPOSE: To evaluate the potential use of fluorescence confocal microscopy (FCM) for ex vivo diagnosis and excision margin assessment of conjunctival neoplasms. DESIGN: Validity study. METHODS: setting: Single institution. PARTICIPANTS: Consecutive patients with clinically suspicious conjunctival lesions. INTERVENTION: Conjunctival lesions were excised in toto using a standard "no-touch technique" by a single surgeon (A...

An 8-year-old healthy boy underwent surgery for excision of a painless, enlarging vascularized conjunctival tumor. Histopathology disclosed a mass comprised of interweaving spindle cells and scattered histiocytes in a fibrous matrix, consistent with benign fibrous histiocytoma. This rare tumor can resemble several conditions, including scleritis/episcleritis, inflamed pterygium, juvenile xanthogranuloma, foreign body granuloma, solitary fibrous tumor, amelanotic melanoma, and squamous cell carcinoma.

Melanoma of the conjunctiva is a rare tumor with incidence from 0,03 to 0,08 cases per 100000 white population. Metastatic malignant melanoma represents approximately 5% of all secondary malignant lung tumors. We report the unexpected discovery of a pulmonary and pleural metastasis from a conjunctival melanoma in a young subject.

BACKGROUND: The management of conjunctival melanoma is difficult because of the rarity of the disease, confusing terminology, high rates of local tumor recurrence, controversies regarding treatment, a poor evidence base, unreliable prognostication, and significant mortality rates. METHODS: The medical literature was reviewed, focusing on treatment and management options for conjunctival melanoma. Recent trends and developments were summarized with respect to terminology, local treatment, histology, genetic analysis, prognostication, and systemic treatment, highlighting the scope for research and possible improvements in patient care...

Conjunctival malignant melanoma is a rare disease associated with considerable mortality. Most published data have been based on case reports or series of referred patients. In addition, very little is known about the genetic and epigenetic profile of conjunctival melanoma and the resemblance to uveal, cutaneous and mucosal melanoma. The aim was to determine the incidence rate of conjunctival melanoma, and to relate clinicopathological features and treatment to prognosis. A further aim was to determine the prevalence of BRAF mutations in conjunctival melanoma, to determine whether BRAF mutations are early events in pathogenesis, and relate clinicopathological features and prognosis to BRAF-mutation status...

BACKGROUND: Patients with xeroderma pigmentosum (XP) are strongly predisposed to the development of numerous cutaneous cancers. However, the extent of ocular pathology in these patients has not been adequately studied. METHODS: We conducted a retrospective study of tumors involving the ocular surface and ocular adnexa from 6 XP patients. Histopathological evaluation and immunohistochemistry was performed using antibodies directed against the most common mutated proteins in XP (XPA, XPC, and XPD)...
