Choroidal nevus through a broader vision: Retinal imaging acquisition captured with Broad Line Fundus Imaging technology.

OBJECTIVE: To describe the peculiarities in imaging acquisition of fourteen patients with choroidal nevus using the Broad Line Fundus Imaging (BLFI) technology. METHODS: Single-center, retrospective, cross-sectional analysis. RESULTS: All images were acquired using the BLFI technology. We have found that choroidal nevus is undetectable in the blue channel (BC) (435-500 nm) and the green channel (GC) (500-585 nm). The only visible changes are related to the drusen, which appeared in BC and GC as light focal dots, correlated to the yellowish foci in the true-color image. On the red channel (RC) (585-640 nm), all lesions revealed the same pattern: a well-defined dark spot, with enhanced contrast, allowing the better visualization, measuring, and characterization of the nevus when compared with the other color channels, including the true-color imaging. CONCLUSION: BLFI application in choroidal nevus might be helpful at presentation, refining the diagnostic reliability, and monitoring, as it allows for better detection of alterations in the lesions. The peculiarities of the choroidal nevus are better assessed when using the RC due to its longer wavelength and deeper penetration in the retina and choroid.

Granular Cell Tumor Located in the Bulbar Subconjunctival Space.

AIM: To report an unusual case of granular cell tumor. METHODS: Case report. RESULTS: A 14-year-old male presented with a bulbar conjunctival yellowish nonmovable mass, in the left eye. The tumor was removed and histopathologic evaluation revealed a granular cell tumor. CONCLUSION: Granular cell tumor can occur at the bulbar subconjunctival space.

Optic Disc Pyogenic Granuloma.

AIM: The aim of this paper was to report a rare presentation of adenoid cystic carcinoma. METHOD: This is a case report presenting clinical, radiographic, and histopathologic findings. RESULTS: A 72-year-old female with no reported ocular symptoms was found to have an incidental right orbital mass on imaging. Additional studies revealed multiple liver lesions, which were biopsied and found to be consistent with adenoid cystic carcinoma. She was then referred to the ophthalmology service, where ocular examination demonstrated 2.5 mm of right proptosis with elevation and abduction deficits. Diplopia could be elicited in extreme upgaze and right lateral gaze. An excisional biopsy of the orbital mass was performed, with histopathology confirming the diagnosis of primary adenoid cystic carcinoma of the lacrimal gland, thereby also supporting the initial suspicion that the hepatic adenoid cystic carcinoma lesions represented metastases. CONCLUSION: The authors describe a rare presentation of adenoid cystic carcinoma of the lacrimal gland, initially asymptomatic, with metastatic lesions restricted to the liver at the time of diagnosis. Three previous cases of adenoid cystic carcinoma with isolated metastatic hepatic lesions at the time of diagnosis have been reported; all of these cases localized the primary tumor to the salivary glands.

Isolated uveal tuberculoma masquerading as an intraocular tumor in an immunocompetent patient-a clinical-pathologic study with diagnosis by PCR.

PURPOSE: The aim of this article is to report a case of uveal tuberculoma simulating an intraocular tumor in which the diagnosis was only possible by polymerase chain reaction (PCR) analysis. METHOD: This is a case report. RESULTS: A36-year-old male presented with a progressive growing intraocular tumor and no history or positive test for other systemic disease. The eye eventually turned blind and painful and was enucleated. Histopathologic analysis revealed a granulomatous reaction and caseation necrosis but failed to identify any causative microorganisms. Final tuberculosis diagnosis was only possible by quantitative PCR. CONCLUSION: Isolated uveal tuberculoma can present in an otherwise healthy patient with negative systemic tuberculosis evaluation. PCR can be used to confirm tuberculosis when other methods have failed.

Comprovação anatomopatológica da presença de tecido vascular e nervoso evidenciado à ecografia como eco tangencial ao descolamento de coróide: relato de dois casos / Histopathologic confirmation of vascular and nervous tissue identified on ultrasound as an tangential image to choroidal detachment: report of two cases

São apresentados dois casos de descolamento de coróide em olhos com endoftalmite submetidos a enucleação. O estudo anatomopatológico permitiu identificar a presença de tecido vascular e nervoso interpondo-se entre a esclera e coróide deslocada, como havia sido evidenciado pela ecografia.

Two cases of endophthalmitis with choroidal detachment submitted to enucleation are presented. The histopathologic study allowed the identification of vascular and nervous tissue between the choroid and sclera, as it was seen on ultrasound examination.

Melanocitoma associado à membrana neovascular sub-retiniana / Melanocytoma associated to subretinal neovascular membrane

Relatamos caso de melanocitoma de disco óptico associado à membrana neovascular sub-retiniana. O paciente apresentava diminuição da visão, presença de descolamento seroso de retina, com hemorragia e exsudação e foi encaminhado com o diagnóstico de melanoma de coróide e sugestão de enucleação. São discutidas as principais características dos dois tumores e os detalhes do diagnóstico diferencial.

We report a case of optic disc melonocytoma associated to subretinal neovascular membrane. The patient presented with low visual acuity, serous retinal detachment with haemorrhage and exudates and was referred with the diagnosis of melanoma and an orientation to enucleate the eye. We discuss the major aspects of both tumors and the details of differential diagnostic.

Foreign body after pterygium surgery simulating an epibulbar tumor.

A 60-year-old woman was referred for evaluation of a rapidly growing conjunctival neoplasm after pterygium surgery. The lesion proved to be a foreign body granuloma, with exogenous material that seemed to be cotton mesh, probably used for tamponade of subconjunctival bleeding that was unintentionally left in place.

Mixoma da conjuntiva em adolescente / Conjunctival myxoma occuring in a teenager

Objetivo: Relatar caso atípico de mixoma da conjuntiva. Relato de caso: Paciente feminina, 11 anos de idade, com lesão em conjuntiva nasal esquerda notada há um mês. Ao exame a lesão não apresentava mobilidade, sendo feita suspeita de doença linfoproliferativa ou tumor estromal. Submetida à excisão cirurgica teve diagnóstico final de moxoma da conjuntiva. Apresentou recidiva da lesão dois meses após a primeira cirurgia, sendo submetida à nova excisão. Após 18 meses não havia sinal de doença recorrente. Comentários: O caso descrito é peculiar devido à baixa idade de apresentação, localização nasal, aderência ao tecido episcleral e ocorrência de recidiva da lesão.

Fordyce nodules in a buccal membrane graft to the ocular surface.

PURPOSE: To present a case of epibulbar Fordyce nodules, with a referral diagnosis of primary tumor. METHODS: Case report. RESULTS: A 38-year-old woman was referred for ocular oncology consultation because of a conjunctival lesion in the right eye. She had had a buccal mucous graft to treat recurrent pterygium 18 years earlier. The lesion consisted of multiple small, yellow granules over a pink, thickened mucosa from the 12 to 3 o'clock meridians. Excisional biopsy revealed multiple subepithelial sebaceous glands consistent with Fordyce nodules. CONCLUSIONS: Fordyce nodules are a possible late benign complication of buccal mucous grafts.

Osseous choristoma of the conjunctiva simulating extraocular extension of retinoblastoma.

PURPOSE: To report the clinicopathologic features of an epibulbar osseous choristoma simulating extraocular extension of retinoblastoma. DESIGN: Interventional case report. METHODS: A 7-month-old male presented with a unilateral intraocular mass localized to the temporal retina and a white pedunculated lesion extending from the conjunctiva, anterior to the insertion of the lateral rectus muscle. Clinical examination and computed tomography scan findings led to the diagnosis of retinoblastoma with extraocular extension. The child underwent excision of the epibulbar lesion and enucleation of the globe. RESULTS: The histopathologic examination of the epibulbar lesion revealed an osseous choristoma. The intraocular contents displayed features typical of retinoblastoma without extraocular extension. CONCLUSION: An epibulbar osseous choristoma can simulate extraocular extension of retinoblastoma in an eye harboring the intraocular malignancy.
