Pigmented epithelial tumours of the conjunctiva.
Two out of 60 conjunctival epithelial tumours reviewed between 1973 and 1989 were found to be pigmented. One tumour was a pigmented papilloma and the other a pigmented squamous cell carcinoma. The melanin pigment was found in epithelial tumour cells as well as in macrophages, dendritic melanocytes, and Langerhans cells. The distinction between the latter two types of cells was possible in one o...
متن کاملNucleoside transport mechanisms in the pigmented rabbit conjunctiva.
PURPOSE To elucidate the mechanisms of nucleoside transport in the pigmented rabbit conjunctiva using [3H]uridine as the substrate. METHODS Excised pigmented rabbit conjunctiva was mounted in a modified Ussing chamber for measurement of short-circuit current (Isc) and [3H]uridine transport. RESULTS [3H]Uridine transport in the mucosal-to-serosal direction at 10 microM exhibited directionali...

AIMS/BACKGROUND Ten patients with metastatic tumours to the conjunctiva and the clinical aspects of this rare form of ocular metastasis are described in this study. METHOD All patients with ocular and adnexal metastatic tumours referred to an ocular oncology service were reviewed and those having conjunctival metastases were studied for the site of their primary tumour, clinical features, and...
متن کاملThe conjunctiva in corneal epithelial wound healing.
BACKGROUND/AIMS During the healing of corneal epithelial wounds with limbal involvement, conjunctival epithelium often migrates across the denuded limbus to cover the corneal surface. It is believed that, over a period of time, conjunctival epithelium covering the cornea assumes characteristics of corneal epithelium by a process referred to as conjunctival transdifferentiation. The purpose of t...
متن کاملUniform distribution of epithelial stem cells in the bulbar conjunctiva.
PURPOSE To determine the distribution of epithelial stem cells in the bulbar conjunctiva by measuring homeostatic movements and mitosis of epithelial cells in this region. METHODS The ubiquitous GFP mouse was used to monitor movement of conjunctival epithelial cells. Cell movement was determined by histology, analyzing the shape and distribution of GFP cell clusters in flat wholemount specime...
