Rosai-Dorfman Disease involving the eye and ocular adnexa. Clinicopathologic series of 17 patients.

Purpose: To describe the clinical features and histopathologic findings of Rosai-Dorfman disease (RDD) with ophthalmic involvement diagnosed at a Mexican ophthalmologic referral center in a period of 62 years.

Results: A total of 17 cases of RDD with ophthalmologic manifestations in Mexican-mestizo patients were collected. Female predominance was observed in 12 of 17 patients.

Clinical and histopathological features of conjunctival "Teddy bear" granuloma: A case series.

Purpose: To describe the clinical features, histopathological findings, and prognosis of conjunctival Teddy bear granuloma (TBG) diagnosed in a Mexican ophthalmologic referral center in a period of 64 years.

Methods: We reviewed clinical and histopathological material from all patients with documented conjunctival TBG. Patient's age, gender, location, clinical signs and symptoms, duration, treatment and, specimen size, were evaluated.

Vitreous involvement as initial presentation of hereditary transthyretin amyloidosis related to the rare TTR Ile107Met (p.Ile127Met) pathogenic variant.

Background: Hereditary transthyretin amyloidosis (ATTR) is a multisystemic disease with autosomal dominant inheritance, characterized by the deposition of amyloid-insoluble proteins. We describe a case of vitreous amyloidosis as the initial presentation of ATTRv amyloidosis resulting from the rare Ile107Met (p.Ile127Met) pathogenic variant.

Conjunctival Myxoma: High-Resolution Optical Coherence Tomography Findings of a Rare Tumor.

Purpose: The purpose of this study was to describe 2 cases of biopsy-proven conjunctival myxomas and present their optical signs on high-resolution optical coherence tomography (HR-OCT) with clinical and histopathological correlations.

Methods: Two middle-aged female patients with a clinical diagnosis of conjunctival cysts were referred for surgical treatment. Clinical assessment, photographs, ultrasound biomicroscopy, and HR-OCT images were obtained.

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.

[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.

Periocular myxoma in a child.

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.

Advanced conjunctival melanoma.

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.
