Abstract
PURPOSE To evaluate the observed and relative survival of patients diagnosed with a malignant melanoma in the ocular region in Denmark during the period 1943-97. METHODS The study included 2,504 patients (1,292 men and 1,212 women) diagnosed with a melanoma in the ocular region, of which 2,434 cases could be topographically subclassified into 2,178 in the choroid/ciliary body, 141 in the iris, and 115 in the conjunctiva. The patients were followed through 2002 and the observed survival proportions and relative survival ratios were estimated. RESULTS For the total ocular region and the choroid/ciliary body, the observed survival did not vary statistically significantly with the year of diagnosis. A statistically insignificant higher observed survival for women than men was found for tumors in the ocular region and the subgroups choroid/ciliary body, iris, and conjunctiva. During the 55-year study period, the 5- and 10-year relative survival remained stable for the ocular region for men at 67% and 57% and for women at 71% and 60%, respectively, and stable for the choroid/ciliary body for men at 66% and 55% and for women at 69% and 57%, respectively. The 5- and 10-year relative survival for the iris was for men 90% and 85% and for women 99% and 101%, respectively, and for the conjunctiva for men 83% and 70% and for women 93% and 82%, respectively. CONCLUSION The observed and relative survival of patients diagnosed with a melanoma in the ocular region and choroid/ciliary body in Denmark during the period 1943-97 and followed through 2002 has remained stable. The highest observed and relative survival was found for iris melanomas, the lowest for choroid/ciliary body melanomas, and intermediate for conjunctival melanomas.

Abstract
Primary ocular melanoma can involve the uveal tract, conjunctiva, eyelid, or orbit. Uveal melanoma is the most common ocular melanoma and carries a serious prognosis, especially if the tumor is medium or large in size. Conjunctival melanoma manifests on the surface of the eye and has been increasing in incidence. Eyelid and primary orbital melanoma are the least common variants. Early diagnosis from annual ocular examination by an experienced ophthalmologist and treatment strategies are reviewed.

Abstract
Lesions of the caruncle are uncommon. On account of the histological composition of the caruncle, which includes, in addition to conjunctiva, hair follicles, sebaceous glands, sweat glands, and accessory lacrimal tissue, the caruncle may develop lesions that may be similar to those found in the skin, conjunctiva, or lacrimal gland. Clinical preoperative diagnosis is very difficult and reached only in about half of the cases. The vast majority of lesions of the caruncle are benign, mainly nevi. Reported malignant lesions are very rare but can be potentially fatal. Although malignancy is clinically overestimated, any suspected malignant lesion should be excised and examined histopathologically by an experienced pathologist. This study presents the clinical and histological data of 42 consecutive caruncular lesions processed at our laboratory and reviews previously reported cases of caruncular lesions.

Abstract
Prolapsed uveal tissue through a cataract incision can simulate any pigmented epibulbar mass, including conjunctival melanoma, extraocular extension ofa ciliary body or choroidal melanoma, and pigmented squamous cell carcinoma of the conjunctiva. The authors describe an 88-year-old woman who presented with an enlarging pigmented epibulbar mass on the left eye. Although the lesion closely simulated a conjunctival melanoma or extraocular extension of a uveal melanoma, closer evaluation revealed thin uveal tissue extending through partial wound dehiscence from cataract surgery that was performed 3 years earlier. The lesion was consistent with prolapsed uveal tissue through a cataract wound masquerading as a melanoma. Therefore, uveal prolapse should be considered in the differential diagnosis of conjunctival melanoma or extraocular extension of uveal melanoma.

Abstract
PURPOSE To describe 5 patients with pigmented conjunctival squamous cell carcinoma in situ. DESIGN Retrospective noncomparative case series. PARTICIPANTS Five patients. METHODS Clinical and histopathologic features were reviewed. MAIN OUTCOME MEASURES Relationship of clinical and histopathologic features to carcinoma pigmentation. RESULTS All 5 patients were male. Two were Hispanic, 2 were Caucasian, and 1 was Asian Indian. Localized racial melanosis was evident in 3 cases and no case showed diffuse racial melanosis. The tumor showed leukoplakia (n = 1) and was at the temporal limbus (n = 4) or nasal limbus (n = 1). The mean tumor basal dimension was 9.2 mm and mean thickness was 3.2 mm. Brown pigment was present deep within the tumor in all 5 cases, involving 50% to 90% of the mass. In each case, pigmented squamous cell carcinoma was suspected; melanoma was a second possibility. Histopathology revealed in situ squamous cell carcinoma (conjunctival intraepithelial neoplasia) with pigmented dendritic melanocytes in all 5 cases. Pigment was also found within neoplastic cells (n = 2). After surgical resection, there was no recurrence over mean follow-up of 23 months. CONCLUSIONS Squamous cell carcinoma in situ can manifest as a pigmented tumor, resembling melanoma, in both Caucasians and non-Caucasians, primarily due to intratumoral pigmented dendritic melanocytes.

Abstract
A 73-year-old male with a history of bladder carcinoma presented with conjunctival melanoma that was excised. Multiple lung metastases were detected during diagnostic work-up. Because of uncertainty about the histology of the metastatic lung tumor, a biopsy was performed that revealed a third primary non-small cell carcinoma of the lung. This case illustrates the need to obtain histological verification in patients with conjunctival melanoma and distant metastases, especially if metastases are detected early in the follow-up.

Abstract
BACKGROUND Primary episcleral melanoma is exceedingly rare. We report a case of primary episcleral melanoma in an eye with ocular melanocytosis. METHODS Interventional case report with presentation of clinical photographs and histopathology. RESULTS A 62-year-old man with long-standing ocular melanocytosis presented with a new, raised, darkly pigmented lesion on the episclera. Clinical examination and ultrasound biomicroscopy showed no evidence of intraocular mass or nevus. Lamellar scleroconjunctivectomy of the lesion was performed, and histopathologic analysis revealed episcleral melanoma with no evidence of intra- or extra-ocular extension. He was later treated with cryotherapy to the surgical bed. Continued observation shows no evidence for intraocular tumor or recurrence of episcleral tumor. CONCLUSIONS Primary episcleral melanoma is a previously unreported complication of ocular melanocytosis, and should be considered in the differential diagnosis in patients with ocular melanocytosis and pigmented nodules on the ocular surface.

Abstract
PURPOSE To investigate racial and ethnic differences in the incidence of conjunctival melanoma in a large population-based study. DESIGN Observational cross-sectional study. METHODS Using data from 1992 through 2003 provided by the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program, we calculated age-adjusted incidence rates of conjunctival melanoma in various racial and ethnic groups (Black, American Indian, Asian and Pacific Islander, Hispanic, and non-Hispanic White). In addition, we calculated the standard incidence ratios (risk ratios) and 95% confidence intervals to describe the differences within these racial and ethnic groups. RESULTS From 1992 through 2003, there were a total of 168 conjunctival melanomas diagnosed in 13 SEER registries with known racial and ethnic groups. The annual age-adjusted incidence rates (per million population) of conjunctival melanoma was 0.18 (Blacks), 0.17 (American Indians), 0.15 (Asians), 0.33 (Hispanics), and 0.49 (non-Hispanic Whites). The difference in the incidence of conjunctival melanoma between Whites and Blacks or Asians was statistically significant, but was not significant between Blacks and Asians. CONCLUSIONS The overall White-to-Black incidence ratio in conjunctival melanoma was 2.6:1, which is much less than that of uveal melanoma (18:1) and cutaneous melanoma (13:1 to 26:1), but is similar to that of mucosal melanoma (2.2:1 to 2.3:1). The cause and significance of this difference of racial and ethnic incidence in various melanomas are discussed.

Abstract
PURPOSE To evaluate the clinical features and risks for transformation of conjunctival primary acquired melanosis (PAM) into melanoma. DESIGN Noncomparative case series. PARTICIPANTS Three hundred eleven eyes with conjunctival PAM without melanoma at initial examination from a single-center tertiary referral center. METHODS Retrospective chart review with evaluation of the clinical features of PAM at initial presentation and follow-up. Times to PAM enlargement, recurrence, and transformation into melanoma were assessed using Kaplan-Meier estimates. Risk factors for these outcomes were analyzed using Cox proportional hazards regressions. MAIN OUTCOME MEASURES Primary acquired melanosis enlargement, recurrence, and transformation into melanoma. RESULTS Mean patient age at diagnosis of PAM was 56 years (range, 15-90), 62% were female, and 96% were Caucasian. The conjunctival quadrant(s) affected by PAM were temporal (57%), inferior (45%), nasal (42%), and superior (37%). The anatomic location(s) of PAM included bulbar conjunctiva (91%), limbal conjunctiva (55%), cornea (23%), forniceal conjunctiva (13%), palpebral conjunctiva (12%), and caruncle (11%). Primary acquired melanosis extended for a mean of 3 clock hours (range, 1-12). Initial management included observation (n = 194 eyes [62%]), biopsy combined with cryotherapy (n = 107 eyes [34%]), and topical chemotherapy and/or cryotherapy without biopsy (n = 10 [4%]). Of PAM that was observed, Kaplan-Meier estimates at 10 years revealed PAM enlargement in 35% and transformation into melanoma in 12%. Of those that underwent incisional or excisional biopsy, 10-year estimates of PAM recurrence and transformation into melanoma were 58% and 11%, respectively. Progression to melanoma occurred in 0% of cases of PAM without atypia, 0% of cases of PAM with mild atypia, and 13% of cases of PAM with severe atypia. Of the 9 patients with PAM who developed melanoma, none have developed systemic metastasis. Multivariable analysis revealed that the most significant factor for both PAM recurrence and progression to melanoma was extent of PAM in clock hours. CONCLUSION Primary acquired melanosis without atypia or with mild atypia shows 0% progression to melanoma, whereas PAM with severe atypia shows progression to melanoma in 13%. The greater the extent of PAM in clock hours, the greater the risk for transformation to melanoma.

Abstract
BACKGROUND Conjunctival melanoma is a relatively rare ocular malignancy with substantial associated morbidity and mortality. METHODS More than 100 articles on conjunctival melanoma were reviewed, including most of the relevant recent publications cited in a current MEDLINE search. The author's experience with conjunctival melanomas is also incorporated in this review. RESULTS Recognition of their precursor lesions at an early stage is important. Staging of the disease by sentinel lymph node biopsy is now advocated in some centers. Surgical excision with adjuvant cryotherapy and alcohol corneal epithelialectomy is usually effective in eradicating most of these lesions. Extensive cases of flat primary acquired melanosis with atypia may be managed with mitomycin C. Multifocal and advanced melanoma, especially in cases showing intraocular or orbital invasion, may require exenteration and/or radiotherapy to adequately extirpate the neoplasm locally. However, systemic metastases already may have occurred in these patients with advanced disease. CONCLUSIONS Conjunctival melanoma is a condition of concern because of its rarity and lethal potential. Advances in the understanding and management of this neoplasm have markedly reduced the mortality and possibly the morbidity associated with this malignancy.

Abstract
PURPOSE OF REVIEW Numerous conjunctival tumors can occur in children, originating from tissues of choristomatous, epithelial, melanocytic, vascular, fibrous, xanthomatous and lymphoid. Overall, 97% prove to be benign and only 3% are malignant. RECENT FINDINGS The most common malignancies include conjunctival lymphoma and melanoma. In our experience, the most common conjunctival tumors in children include nevus (64%), dermolipoma (5%), lymphangioma (3%) and capillary hemangioma (3%). Conjunctival nevi can manifest as a darkly pigmented (65%), lightly pigmented (19%) and completely nonpigmented (16%) mass. Most nevi occurred at the nasal or temporal limbus, without involvement of the cornea. Occasionally, they are located in the caruncle, but rarely are nevi found in the fornix or tarsal conjunctival surface. Intralesional cysts are visible in 65% of nevi. Change in nevus color over time has been noted in 5% of cases and change in nevus size has been documented in 7%. Evolution of conjunctival nevus into malignant melanoma is extremely low (<1%). SUMMARY Conjunctival nevus is the most common conjunctival tumor in children and fewer than 1% evolve into melanoma over time.

Abstract
PURPOSE Conjunctival melanoma is rare in children. This article presents a comprehensive review and discusses the clinical significance of the published cases of malignant melanoma of the conjunctiva in children younger than 15 years. MATERIALS AND METHODS To obtain prior reports of conjunctival melanoma in children, a systematic search of the world literature was conducted. Additional studies were identified from the bibliographies of the retrieved articles, as well as from major ophthalmic textbooks. RESULTS A review of the literature resulted in 28 reported cases of conjunctival melanoma in children younger than 15 years, and only 8 had adequate case details. CONCLUSION Malignant melanoma of the conjunctiva is a rare condition in children. Limited knowledge for management and prognosis of this condition in children is largely due to its low occurrence.

Abstract
The aim of the study is to discuss the pattern and risk factors for metastatic disease in conjunctival melanoma. We draw comparisons with cutaneous metastatic melanoma. We describe the clinical course of a patient with recurrent conjunctival melanoma in the context of primary acquired melanosis with atypia. The local disease was eventually treated with a lid splitting exenteration. The patient suffered from an isolated distant metastasis to the gastric wall that was managed by partial gastrectomy. Conjunctival melanoma has many similarities with its cutaneous counterpart. In both conditions the regional lymph nodes are the most common site for metastases, however, isolated distant metastases can occur. Gastric metastases are frequently seen in cutaneous melanoma. This is the first report of an isolated gastric metastasis from a conjunctival melanoma.

Abstract
The current World Health Organization classification of conjunctival melanocytic proliferations divides them into conjunctival nevi and invasive melanoma but, in contrast to other anatomic sites, does not recognize melanoma in situ. All atypical intraepithelial conjunctival proliferations are included in a heterogeneous category designated as primary acquired melanosis (PAM) with atypia. We performed clinicopathologic analysis of 29 cases of PAM with atypia. On the basis of histologic features and frequency of association with invasive melanoma and metastases, we were able to divide our cases into 2 histologic groups. The low-risk group (13 cases) included lesions composed of small to medium size melanocytes with high nuclear to cytoplasmic ratio and small to medium size hyperchromatic nuclei devoid of nucleoli showing predominantly single cell lentiginous growth pattern. Invasive melanoma occurred in only 2 cases from this group. None of these lesions metastasized. The second, high-risk group (16 cases), showed increased frequency of association with invasive melanoma (15/16 cases, 94%) and metastases (4/16 cases, 25%). These lesions were more heterogeneous architecturally but were all composed of melanocytes showing various degrees of epithelioid features such as abundant cytoplasm, vesicular nuclei, or prominent nucleoli. In 4 cases discrete areas showing high-risk and low-risk features were identified. All 4 lesions were associated with invasion. Our findings offer a practical approach for prognostically useful subclassification of PAM with atypia, which emphasizes cytologic features of intraepithelial conjunctival melanocytic proliferation.

RESULTS 6 cases predominantly involving the temporal conjunctiva metastasised to the pre-auricular lymph nodes. Two cases predominantly involving the nasal conjunctiva metastasised to the submandibular nodes. Of the two cases with purely multifocal disease, one metastasised to the pre-auricular nodes and another to both submandibular and parotid nodes. One primary conjunctival malignant melanoma had its origin in temporal conjunctiva but metastasised to submandibular nodes, and another case originating from nasal conjunctiva metastasised to pre-auricular nodes. CONCLUSIONS Temporal conjunctival melanotic lesions tend to metastasise clinically to pre-auricular lymph nodes and nasal conjunctival melanotic lesions metastasise to the submandibular lymph nodes. Patterns appear consistent with laboratory-based anatomically mapped lymphatic drainage basins of the conjunctiva.

Abstract
Surgical excision with cryotherapy is a well-established treatment option for malignant melanoma or primary acquired melanosis (PAM) with atypia of the conjunctiva and cornea. Topical chemotherapeutic agents such as mitomycin C (MMC) however, are increasingly finding use in clinical practice. A search was performed of Medline and Pubmed databases for English language articles from 1980 to the present in this field. Relevant studies were reviewed with regards to treatment regimen, rates of recurrence and metastasis, side effect profile and length of follow up. A total of 22 and 16 unique cases of biopsy proven PAM with atypia and malignant melanoma, respectively, treated with topical MMC were identified. Topical MMC was well tolerated and shows considerable promise, particularly in the treatment of diffuse PAM with atypia. However, long-term data are lacking and further studies are required.

Abstract
PURPOSE To determine the types and incidence of caruncular lesions and to investigate the correlation between clinical and histologic diagnosis. DESIGN Retrospective, observational case series. METHODS Records of patients with a lesion of the caruncle that was excised and submitted to our ocular pathology department between January 1979 and May 2005 were reviewed. Lesions were classified by histologic type and correlated with patient age, gender, and preoperative clinical diagnosis. RESULTS A total of 195 consecutive caruncular lesions from 191 patients were identified. Twenty-four different types of lesions were identified; the most common were nevi (n = 92, 47%) and papillomas (n = 29, 15%). One keratoacanthoma was identified. One hundred eighty-three lesions (93.8%) were benign, six (3.1%) were premalignant, and five (2.6%) were malignant. Preoperative clinical diagnosis corresponded to postexcision histologic diagnosis in 73 cases (37.4%). Suspected malignancy was a common reason for excision (61 cases, 31.3%), but malignancy was confirmed in only three (4.9%) of 61 cases. Two of the five malignant lesions were clinically thought to be benign. CONCLUSIONS We hereby report the first caruncular keratoacanthoma. The rarity and variety of caruncular lesions make clinical diagnosis difficult. Malignancy is clinically overestimated, and some malignant lesions can take a benign aspect, justifying close photographic follow-up of all lesions. Because caruncular malignant melanoma is associated with poor prognosis, pigmented lesions should be monitored carefully. In the absence of clear criteria for malignancy, any change in color, size, or vascularization of a caruncular lesion should hasten excision.

Abstract
BACKGROUND Malignant melanoma of the conjunctiva is a rare tumour with an unpredictable behaviour, characterised by the high risk of local recurrence and metastatic spread. Intraocular extension of a conjunctival melanoma is rare. We present three cases of primary conjunctival melanoma with intraocular extension. METHODS Three patients presented with primary conjunctival melanomas, which either arose at or later involved the limbus on a background of primary acquired melanosis. Despite adequate primary local excision and adjuvant chemotherapy, all three patients experienced several recurrences, requiring further surgery. Two of the patients had excision of the tumour that required superficial keratectomy. One of these patients then required two further procedures in which the anterior chamber was breached. RESULTS All three patients ultimately required enucleation or exenteration to control local disease. All three specimens showed intraocular extension. CONCLUSIONS The management of conjunctival melanoma can be difficult. In addition to local recurrence and metastases, limbal melanomas may rarely show intraocular extension, particularly if surgery to excise the tumour requires the removal of Bowman's membrane. Regular follow-up of these patients is mandatory.

Abstract
PURPOSE Pigmented lesions of the conjunctiva are often difficult to classify clinically. Exfoliative cytology may be helpful, but reliable data regarding the sensitivity and specificity of this test are currently lacking. We determined the value of exfoliative cytology with regard to pigmented conjunctival lesions. METHODS A total of 294 smears from 182 patients were screened for malignancy within 6 months of exfoliative cytology. Smears were classified according to the following categories: grade 0 = insufficient material for diagnosis; grade 1 = normal conjunctival cells; grade 2 = melanocytes with mild atypia; grade 3 = melanocytes with moderate atypia, and grade 4 = melanocytes with severe atypia. RESULTS The sensitivity, specificity, positive predictive value and negative predictive value of exfoliative cytology were 85%, 78%, 59% and 93%, respectively. CONCLUSION Exfoliative cytology is a fast, easy and non-invasive technique that may be used in the evaluation of patients with a pigmented conjunctival lesion.

Abstract
BACKGROUND/AIMS The authors investigated the expression of S100A1, S100A6, S100B, MelanA, and CEA in conjunctival naevi, primary acquired melanosis (PAM), conjunctival melanoma, and uveal melanoma in order to assess their potential usefulness in the pathological differential diagnosis of these entities. METHODS Paraffin embedded sections of 18 conjunctival naevi, 14 PAM, 16 conjunctival melanomas, and 20 uveal melanomas were immunostained for S100A1, S100A6, S100B, MelanA, and CEA, and expression was scored semiquantitatively. RESULTS Expression of S100A1 differed significantly between conjunctival naevi and conjunctival melanoma, with percentages of positive cells of 30.6% and 71.4%, respectively. Conjunctival melanomas had high average scores for S100A1 and S100B (71.4%, 62.9%, respectively), while uveal melanomas also had high S100A1 but low S100B scores (88.5%, 18.5%, respectively). MelanA was highly variable; naevi and uveal melanoma had higher average scores than conjunctival melanoma. CEA was hardly detectable in all four groups. CONCLUSION S100A1 seems to be a possible candidate to differentiate conjunctival naevi from conjunctival melanoma. S100B seems to differentiate between uveal melanoma and conjunctival melanoma. However, the study size was small and therefore the data have to be confirmed by others.

Abstract
PURPOSE To investigate the clinical features and course of conjunctival malignant melanoma in Korea. METHODS The medical records of 15 patients, 5 males and 10 females, diagnosed with conjunctival malignant melanoma who had been treated at Severance Hospital from May 1991 to March 2004 were reviewed retrospectively. The clinical parameters of the patients, tumors, and treatment were analyzed for their relation to outcome measures. RESULTS The mean age at the time of diagnosis was 53.4 years (+/- 11.7 years). In all cases, the disease was unilateral and all patients had experienced at least one recurrence. Local lymph node metastasis was found in 3 patients (20%) and the mean time to metastasis was 3.5 years. Systemic metastasis was found in 6 patients (40%) and the mean time to metastasis was 9.3 years. There were 5 cases of tumor-related death (33.3%), 4 of which were attributed to systemic metastasis. The Kaplan-Meier estimates of cumulative survival rate were 90% at 30 months and 56.6% at 70 months. CONCLUSIONS Although conjunctival malignant melanoma is a rare disease, it is life-threatening and complete tumor excision at an early stage is mandatory, as is additional therapy to prevent local recurrence and systemic metastasis.

Abstract
OBJECTIVE To evaluate prognostic factors and determine the role of conservative surgery and radiotherapy in managing metastatic conjunctival malignant melanoma (MM) involving preauricular/submandibular lymph nodes. METHOD A retrospective analysis (1990-2003) of clinical and histopathologic data from 12 patients presenting with regional metastases after failed local treatment for conjunctival MM. Patients received a common, multispecialty, conservative management approach: wide local excision, topical cryotherapy or radiotherapy to conjunctival MM (orbital exenteration for more advanced local disease), lumpectomy, and adjuvant "ring" radiotherapy of regional metastases, with chemotherapy for distant metastases. RESULTS Median age at primary diagnosis was 51 (range 28-86) years with equal sex predilection. Six of the 12 patients had primary tumors of the bulbar conjunctiva; the remainder arose in the palpebral conjunctiva, the caruncle, or the fornix. Of 11 originating in primary acquired melanosis (PAM), 2 were amelanotic. Epithelioid tumor cells were noted histologically in seven of eight specimens in which cell type could be determined. Eight tumors metastasised to preauricular nodes, three to submandibular and one to both, with a median interval of 23 (range 12-108) months after primary diagnosis. After conservative surgery and "ring irradiation," 7 of 12 patients remained free of regional nodal relapse at median interval of 16 (range 3-126) months. Five patients developed regional nodal recurrence at median interval of 11 (range 6-13) months, 3 of whom were within radiotherapy portals. Eight patients developed distant metastasis at median interval of 44 (range 22-138) months. Eleven patients had tumor-related death. The mean Kaplan-Meier adjusted survival time after primary diagnosis was 76 months with death ensuing postregional metastasis within a median 18 (range 4-127) months. The sole survivor's follow-up duration was 56 months. CONCLUSION Locoregional metastasis after treatment for conjunctival MM is associated with a poor prognosis. Both epithelioid tumor cells and PAM are associated with disseminating disease and poorer outcome. Literature review has failed to demonstrate advantages of mutilating radical surgery over a conservative approach in this rare disease.

Abstract
PURPOSE To report a case of conjunctival melanoma arising from diffuse primary acquired melanosis (PAM) with atypia in a young black woman in the context of previously published cases of this lesion in blacks. METHODS Retrospective case report with literature review. The number and percentage of conjunctival melanomas occurring in black patients were determined from case series in which race was specified, published from 1950 to the present. RESULTS Nodular multifocal conjunctival melanoma in a 30-year-old black woman was treated using surgical excision and adjuvant cryotherapy. Extensive PAM with severe atypia, including areas of microinvasive melanoma, was treated using topical mitomycin C. Literature review revealed 35 cases of conjunctival melanoma occurring in black patients. No previous reports of mitomycin C use in black patients with melanoma or PAM were identified. CONCLUSIONS Conjunctival melanoma is an exceedingly rare tumor in black patients. The current case brings the total of reported cases to 36. We successfully treated nodular melanoma and diffuse PAM in a young black woman using a combination of excision with cryotherapy and topical mitomycin C, suggesting that these lesions are amenable to the same types of therapy previously described for white patients.

Abstract
The objective of this study was to investigate whether digital surface microscopy (DSM) could be used for the follow-up and comparison of malignant and benign conjunctival pigmented lesions (CPLs). Thirty-nine CPLs [16 de novo malignant melanomas (MMs), one MM arising from primary acquired melanosis (PAM), six PAMs and 16 naevi] were digitally analysed and biopsied. All of the PAMs and 10 naevi, which had not been surgically excised, were followed up using DSM. Thirty parameters were evaluated grouped into four categories: geometry, colour, texture and islands of colour. None of the CPLs that were followed up, which comprised 10 naevocytic naevi and seven PAMs, showed any morphological change at DSM analysis, except for one PAM which developed an MM 1 year later. Of the geometric variables examined, the area, maximum diameter and minimum diameter showed significantly higher values in MMs compared with benign CPLs. With regard to the colour of CPLs, MMs were significantly darker and bluer than naevi. In the texture group, contrast was significantly higher in MMs. In the islands-of-colour group, the imbalance of blue-grey regions and the presence of dark areas were significantly higher in MMs. DSM greatly simplified the follow-up of CPLs, such as PAMs with atypia, by providing satisfactory quality images with high reproducibility; this technique is also easy to use and well accepted by patients. Moreover, this preliminary study allowed us to determine which objective variables could be important for distinguishing between benign CPLs and conjunctival MMs.

METHODS A 48-year-old woman with a history of cutaneous axillary melanoma developed a rapidly growing conjunctival mass. Subsequent systemic evaluation disclosed asymptomatic liver metastasis. The conjunctival lesion was resected. RESULTS Histopathologic evaluation of the conjunctival tumor disclosed an epithelioid cell melanoma located in the conjunctival stroma, without appreciable junctional activity, compatible with metastatic melanoma. CONCLUSIONS Conjunctival metastasis from cutaneous melanoma can rarely be the initial manifestation of disseminated melanoma.

Abstract
OBJECTIVE To report the spectrum and frequency of melanocytic and nonmelanocytic conjunctival tumors in an ocular oncology practice. DESIGN Retrospective noninterventional case series. PARTICIPANTS One thousand six hundred forty-three consecutive patients with a conjunctival mass evaluated at an ocular oncology department. METHODS A chart review was conducted to obtain the clinical features of the patient and tumor and to tabulate and categorize the diagnoses. MAIN OUTCOME MEASURES Tumor diagnosis overall and relative to patient age, race, and gender and relative to tumor location and laterality. RESULTS In 1643 consecutive patients, the tumor was classified as melanocytic in 872 cases (53%) and nonmelanocytic in 771 cases (47%). The nonmelanocytic categories included congenital choristomatous (n = 40 [2%]), epithelial (n = 219 [13%]), vascular (n = 63 [4%]), fibrous (n = 7 [<1%]), neural (n = 1 [<1%]), xanthomatous (n = 1 [<1%]), myxomatous (n = 1 [<1%]), lipomatous (n = 23 [1%]), lacrimal gland origin (n = 12 [<1%]), lymphoid (n = 128 [8%]), leukemic (n = 3 [<1%]), metastatic (n = 13 [<1%]), secondary (n = 54 [3%]) tumors, and non-neoplastic lesions simulating a tumor (n = 206 [13%]). Of the 872 melanocytic lesions, the specific tumor diagnosis was nevus in 454 cases (52%), melanoma in 215 (25%), and primary acquired melanosis in 180 (21%). Patients with choristomatous, vascular, fibrous, xanthomatous, and myxomatous tumors presented at a mean age of <40 years, and those with malignant epithelial, lipomatous, leukemic, and secondary tumors presented at a mean age of >60. Of the 219 patients with epithelial tumors, 80% occurred in males, whereas the incidence of melanocytic lesions was equal in males and females. African-American patients represented only 7% of epithelial tumors, <1% of melanomas, and 8% of lymphoid tumors. CONCLUSION Conjunctival tumors were of melanocytic origin in 53% of cases and nonmelanocytic origin in 47%. Overall, melanocytic tumors, epithelial tumors, and lymphoid tumors accounted for 74% of all cases. These tumors were far more common in Caucasian patients, and epithelial tumors were found more frequently in men.

Abstract
BACKGROUND Conjunctival melanoma is a rare neoplasm with an aggressive behaviour characterized by a high tendency to develop recurrences and metastases. The authors describe the clinicopathological features of four Mexican patients with advanced conjunctival melanoma. METHODS Review of the cases of four patients with advanced conjunctival melanoma seen at an ophthalmologic referral centre in Mexico City. The clinical characteristics, gross findings and histopathological features were noted. RESULTS The mean age of the patients (two women and two men) was 72 years (range 49 to 95 years). The left eye was affected in three cases and the right eye in one. Orbital exenteration was performed in two patients, enucleation in one and complete excision of the mass in one. One patient died 2 years after debulking surgery, and another patient is alive and free of disease 13 years after enucleation; the two other patients were lost to follow-up. The mean largest mass dimension of the tumours was 4 cm (range 3-5.4 cm). Histopathologically, all cases were associated with primary acquired melanosis with atypia. Two cases were composed of epithelioid cells, one of spindle cells, and one of a mixture of epithelioid and spindle cells. In three cases the number of mitotic figures ranged from 3 to 36/10 high-power fields; no mitotic activity could be demonstrated in one case. INTERPRETATION The mean age of our patients at the time of diagnosis was older and their tumours were larger than those reported in other series. All the cases were associated with primary acquired melanosis with atypia. At the time of writing, one patient, who had a 3.3-cm tumour, had survived 13 years without clinically detectable disease.

Abstract
PURPOSE To report the use of ultrasound biomicroscopy in the clinical diagnosis and management of pigmented conjunctival cystic nevi. METHOD Two patients, aged 11 and 18 years, with rapidly growing raised conjunctival melanocytic lesions suspected to be inflamed juvenile conjunctival nevus underwent ultrasound biomicroscopic and histopathologic examinations. RESULTS Ultrasound biomicroscopic examination of the lesions revealed multiple areas of cystic tissue, which is compatible with pathologic finding of compound nevus with epithelial inclusion cysts formation. Furthermore, clear interface was found between the mass and the underlying sclera. CONCLUSION Pigmented conjunctival nevi may obscure cysts under slit-lamp examination. Ultrasound biomicroscopy is a useful diagnostic adjunct to distinguish cysts in conjunctival lesions. Additionally, this technique may be helpful in delineating the extent of lesions prior to excision biopsy.

Abstract
Tumors of the conjunctiva and cornea comprise a large and varied spectrum of conditions. These tumors are grouped into two major categories of congenital and acquired lesions. The acquired lesions are further subdivided based on origin of the mass into surface epithelial, melanocytic, vascular, fibrous, neural, histiocytic, myxoid, myogenic, lipomatous, lymphoid, leukemic, metastatic and secondary tumors. Melanocytic lesions include nevus, racial melanosis, primary acquired melanosis, melanoma, and other ocular surface conditions like ocular melanocytosis and secondary pigmentary deposition. The most frequent nonmelanocytic neoplastic lesions include squamous cell carcinoma and lymphoma, both of which have typical features appreciated on clinical examination. The caruncle displays a slightly different array of tumors compared to those elsewhere on the conjunctiva, as nevus and papilloma are most common, but oncocytoma and sebaceous gland hyperplasia, adenoma, and carcinoma can be found. In this report, we provide clinical description and illustration of the many conjunctival and corneal tumors and we discuss tumor management.

Abstract
This article reviews the current pathogenesis, molecular changes, diagnosis, and treatment of ocular melanomas. Ocular melanomas can involve the eyelid, conjunctiva, intraocular structures, and the orbit. The most common eye melanoma involves the uveal tract and is responsible for approximately 13% of melanoma deaths. Uveal melanomas account for 10% of all melanomas.

Abstract
PURPOSE To describe the principles and preliminary results of plaque brachytherapy for selected orbital malignancies. METHODS A custom-designed Iodine-125 plaque, designed to deliver a target dose of 50 Gray, was placed surgically in the region from which an orbital malignancy was partially resected. The mean dose to the target area was 50 Gray. The initial and follow-up patient data were reviewed. RESULTS Of the 8 patients, the diagnosis was adenoid cystic carcinoma of the lacrimal gland (4 cases), orbital invasion by basal cell carcinoma (2), orbital extension of conjunctival melanoma (1), and metastatic carcinoma (1). Of the 4 with adenoid cystic carcinoma, there was microscopic residual tumor after excision and orbital exenteration was considered. Three have tumor control with follow-up of 1, 3, and 6 years. One patient required exenteration for recurrence separate from the field of brachytherapy and is free of tumor after 10 years. All 4 patients are alive and well with tumor control. Of the 2 patients with orbital extension of basal cell carcinoma, tumor control without recurrence has been achieved in both after 2 years. The patient with orbital metastasis responded to plaque radiotherapy, with no orbital recurrence, but died of systemic metastasis. The patient with orbital melanoma had local orbital recurrence separate from the area of irradiation and is currently being treated for systemic metastasis. CONCLUSIONS Based on preliminary observations, plaque radiotherapy appears to be a reasonable alternative to exenteration and external irradiation for selected orbital malignancies.

Abstract
Sentinel lymph node (SLN) biopsy has emerged as a technique for accurate staging of solid tumors. This technique permits the detection of microscopic metastases in clinically negative regional lymph nodes and may be indicated for malignancies that have a propensity for regional nodal metastasis. With the exception of basal cell carcinoma, almost all malignancies of the eyelid and conjunctiva metastasize to regional lymph nodes as the site of first metastasis. The histologic status of the SLNs has been shown to be the most significant prognostic factor with respect to recurrence and survival in patients with cutaneous melanoma. The indications for and the feasibility of SLN biopsy for eyelid and conjunctival tumors and our experience with this technique are reviewed.

Abstract
AIM To determine prognostic factors for recurrence of disease and tumour related mortality in patients with conjunctival melanoma. METHODS A retrospective analysis of clinical and histopathological data of 69 patients with histologically verified conjunctival melanoma. RESULTS As univariate analysis showed, significant risk factors for the development of recurrence were: irregular pigmentation (RR = 2.0, p = 0.0007), incomplete surgical excision (RR = 3.5, p = 0.008), tumour invasion deeper than in substantia propria (RR = 3.9, p = 0.008), and presence of epithelioid tumour cells (RR = 2.9, p = 0.05). For tumour related mortality a significantly increased risk was found for tumour location in palpebral conjunctiva, caruncle, plica, or fornices (RR = 5.9, p = 0.001), for tumour infiltration deeper than the substantia propria (RR = 5.5, p = 0.001), for incomplete surgical excision (RR = 4.4, p = 0.05), and for nodular or mixed (nodular and superficial) growth pattern of the tumours (RR = 1.2, p = 0.002). The use of an adjuvant therapy for the surgical excision of the melanomas had no statistically significant influence upon the development of recurrent disease nor upon the tumour related mortality. CONCLUSION These data present similar clinical and histopathological risk factors for patients with conjunctival melanoma as reported previously. The present study also addresses the failure of retrospective studies on conjunctival melanoma to prove the efficacy of a supplementary therapy to surgical excision.
