Palpebral Conjunctival and Tarsal Stromal Tumor

Liquid nitrogen-cryopreserved tarsal plate and palpebral conjunctival transplantation for the repair of tarsal defects

The objectives of this study were to compare the efficiency of three methods for repairing tarsal defects (glycerine-preserved, alcohol-preserved and cryopreserved tarsal plate and palpebral conjunctival transplantation) based on histopathological changes and apoptosis, and to evaluate the clinical effects of repairing tarsal defects by liquid nitrogen-cryopreserved tarsal plate and palpebral c...

Sclerosing Stromal Tumor: A Rare Ovarian Neoplasm

Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6% of ovarian stromal tumors. Despite the rarity o...

Conjunctival Stromal Tumor: Expansion of Findings in a Newly Described Entity.

Mucocutaneous junction as the major source of replacement palpebral conjunctival epithelial cells.

PURPOSE The conjunctival epithelium performs an important role in the homeostasis and integrity of the eye. To protect the integrity of the ocular surface, these cells must be replaced from locally concentrated or randomly distributed foci of stem cells. These slow-cycling stem cells produce transient amplifying cells that undergo further divisions before becoming mature conjunctival epithelial...

In vitro growth and differentiation of rabbit bulbar, fornix, and palpebral conjunctival epithelia. Implications on conjunctival epithelial transdifferentiation and stem cells.

PURPOSE The anterior surface of the eye is covered by several physically contiguous but histologically distinguishable epithelial overlying the cornea, limbus, bulbar conjunctiva, fornix conjunctiva, and palpebral conjunctiva. It is important to determine whether the different phenotypes of these epithelia are the result of intrinsic divergence, extrinsic modulation, or a combination of both. B...
