Topical treatment options for conjunctival neoplasms [PDF]

Clinical Ophthalmology, 2008
Topical therapies offer a nonsurgical method for treating conjunctival tumors by delivering high drug concentrations to the ocular surface. Over the past ten years, topical agents have been used by investigators to treat various premalignant and malignant lesions of the conjunctiva, such as primary acquired melanosis with atypia, conjunctival melanoma,

Traumatic iridial extrusion mimicking a conjunctival melanocytic neoplasm [PDF]

ecancermedicalscience, 2016
Conjunctival melanoma is a rare malignant tumour of the eye. Its diagnosis represents a challenge for general pathologists due to low exposure to ocular biopsies and a broad differential diagnosis. In addition, conjunctival samples are often small and are associated with a high frequency of artefacts due to their processing.

Pathology of conjunctival melanocytic neoplasms

Acta Ophthalmologica, 2008
Abstract Purpose To describe the classification, grading and staging of conjunctival melanocytic proliferation. Methods We have audited our experience with conjunctival melanomas, using a novel mapping system and have found shortcomings in the current Tumour Node Metastasis (TNM) staging system.

Bilateral Conjunctival Lesions in Blastic Plasmacytoid Dendritic Cell Neoplasm

Journal of Clinical and Experimental Hematopathology, 2011
The purpose of this study is to report on a patient who developed conjunctival lesions of blastic plasmacytoid dendritic cell neoplasm (BPDCN) after radiation to skin lesions of the same pathological type. A 79-year-old man developed salmon-pink lesions in the lower fornix of the conjunctiva of both eyes and biopsy revealed BPDCN.

A Rare Case Of Conjunctival Rhinosporidiosis Mimicking A Neoplasm In Ghana.

Postgraduate Medical Journal of Ghana, 2022
Introduction: Rhinosporidiosis has not been reported in the literature, in Ghana. It is however endemic in India, mostly presenting as tumorous growths within the nasal cavity and conjunctiva. Rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi an organism initially thought to be a fungus, but now newly classified as ...

Chirality Regulates Stem Cell Fate and Promotes Corneal Epithelial Regeneration via Manipulating Notch Pathway

Advanced Science, EarlyView.
Chirality governs the limbal epithelial stem cell fate. Right‐handed chirality enhances cell proliferation and differentiation, while left‐handed chirality partially maintains cell stemness. By activating the Notch pathway, 3D right‐handed chiral hydrogel offers a drug‐free and cell‐free strategy for effective corneal regeneration.
