Conjunctival myxoma: A systematic review of a rare tumor.

Conjunctival myxoma is an uncommon benign tumor that may develop as a localized disease or as part of the Carney complex, in which case it can cause significant morbidity and mortality. Conjunctival myxomas can mimic other pure or mixed tumors and are often overlooked in clinical practice. Histopathological studies are essential for diagnosis; however, controversy regarding their pathological and immunohistochemical features makes the diagnostic process more difficult.

Intravitreal bromfenac liposomal suspension (100 μg / 0.1 ml). A safety study in rabbit eyes.

Introduction: There is a need to find alternative treatments for MEe. Bromfenac has shown promise in inhibiting the COX-2 enzymatic pathway that partially causes the inflammatory cascade which contributes to the precipitation of ME. However, like other NSAID's, its intraocular half-life is limited.

Conjunctival tattoo with inadvertent ocular globe penetration and vitreous involvement: Clinico-pathological correlation and scanning electron microscopy X-ray microanalysis.

Purpose: The aim is to report a case of conjunctival tattooing with inadvertent injection of tattoo ink into the vitreous cavity and its consequences, the scanning electron microscopy X-ray microanalysis of the ink components, and the microscopic findings of the affected conjunctiva and vitreous.

Methods: Descriptive case report.

Results: A 32-year-old man complained of ocular pain and blurred vision after undergoing a subconjuctival red ink tattoo in his left eye.

Just another metastatic carcinoid tumour to the uveal tract.

We describe the clinic, image, and histopathologic features of a well differentiated neuroendocrine carcinoma (carcinoid tumour) metastatic to choroid and ciliary body in a 52-year-old Mexican Mestizo man. The ophthalmologic examination showed an inferior choroidal mass accompanied by exudative retinal detachment. Ultrasound B-Scan study revealed a diffuse thickened choroid with overlying serous retinal detachment, ultrasound A-Scan revealed a high internal reflectivity solid lesion.

Primary conjunctival myxoma: case series and review of the literature.

Aims: Myxomas are benign soft tissue tumours resembling primitive mesenchyme. They rarely involve ocular structures, and have been recognized in the conjunctiva, eyelids, cornea, and orbit. The aim of this study was to investigate the clinicopathological features of seven patients with primary conjunctival myxoma seen at Dr Luis Sánchez Bulnes Hospital, an ophthalmological referral centre in Mexico City.

Adenoma of the Nonpigmented Ciliary Body and Iris Epithelium in Mexican Mestizo Patients.

The adenoma of the nonpigmented ciliary epithelium is a benign rare tumor, which may present with different clinical characteristics and requires resection along with histopathologic analysis and the identification of specific immunohistochemical markers for an accurate diagnosis. Here, we report a case series of 4 patients in a Mexican mestizo population with this diagnosis, their clinical features, the ultrasound imaging characteristics and the histopathological and immunohistochemical findings.

[Infraorbital schwannoma. Case report].

Background: Infraorbital schwannoma is a benign tumor of the peripheral nerve seath composed of Schwann cells. Usually occurs between 20 and 70 years of age, are usually asymptomatic and can cause progressive, painless proptosis during growth.

Clinical Case: A 32-year-old male admitted to ophthalmologic hospital with a painless, slowly progressive mass above the left lacrimal sac.

[Mesectodermal leiomyoma. Unusual tumor of the ciliary body].

Background: Mesectodermal leiomyoma is a benign tumor of smooth muscle of the ciliary body, which is derived from the neural crest.

Clinical Case: We report the case of a 35-year-old Mexican woman with visually impaired and blurred vision of the right eye of 2 months duration. The clinical and imaging presuntional diagnosis was adenoma of the non pigmented epithelium of the ciliary body and it was surgically resected.

Physical examination and ultrasonography showed an enlarged uterus and a little mass in the right ovary, which was thought to be a fibroma versus pregnancy. Serum levels of chorionic gonadotropin were increased.

Myxomas are locally invasive, benign mesenchymal neoplasms with odontogenic, osteogenic, or soft tissue origin. Facial myxomas probably account for less than 0.5% of all paranasal sinus and nasal tumors.

Congenital smooth muscle hamartoma of the palpebral conjunctiva.

Smooth muscle hamartoma is defined as a disorganized focus or an overgrowth of mature smooth muscle, generally with low capacity of autonomous growth and benign behavior. The implicated tissues are mature and proliferate in a disorganized fashion. A healthy 5-day-old Mexican boy was referred to the authors' hospital in México city for evaluation of a "cystic" lesion of the right eye that had been noted since birth.

Angiolymphoid hyperplasia with eosinophilia of the lacrimal gland: a case report.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare clinicopathologic entity that has been the subject of considerable confusion and debate. ALHE shares both clinical and histopathologic features with Kimura disease (KD). Because of this overlap, ALHE and KD have been used synonymously in the Western medical literature, as they were thought to represent variations of the same disease.

Sebaceous gland carcinoma is considered a relatively rare tumor and represents approximately 1 and 5% of all eyelid tumors. These tumors usually arise in the Meibomian glands of tarsus, in the Zeis glands, and the sebaceous glands of caruncle or eyebrow. In some instances it had multicentric origin, while in other cases the initial location was unable to be determined.
