Conjunctival Myxoma in a 64-year-old patient

Abstract

In addition to preservation of the number of corneal endothelial cells with the use of viscoelastic materials and changes in ultrasound power during cataract surgery, activation of the remaining endothelial cells would be benefi cial. Dexamethasone has been shown to increase the Na+,K+-ATPase activity of bovine corneal endothelial cells in vitro. 5 Topical corticosteroid administration has also proved effective for the treatment of corneal edema, possibly as a result of the activation of corneal endothelial cells. 2 The administration of eyedrops containing 0.1% dexamethasone phosphate maintains corneal endothelial pump rates in patients with Fuchs' dystrophy. 4 These experimental and clinical observations suggest that steroids might promote maintenance of corneal transparency through activation of endothelial cells.

A Rare Presentation of Conjunctival Myxoma with Pain and Redness: Case Report and Literature Review

“…It occurs equally frequently in both sexes; the ages of the patients ranged from 11 to 80 years, with a median of 50 [5, 6, 7, 8]. Chen et al [6] reported the youngest case in an 11-year-old boy; the other cases were in the range of 18–80 years of age.…”

“…We have found only 26 cases reported in the English literature. The typical presentation of conjunctival myxoma is a painless, circumscribed, rubbery, translucent/solid, yellow-pink mass or cyst [5, 6, 7, 8]. Diseases that may resemble conjunctival myxoma include amelanotic nevus, lymphangioma, myxoid liposarcoma, spindle-cell lipoma, myxoid neurofibroma, and rhabdomyosarcoma [9].…”

Conjunctival Myxoma: A Synopsis of a Rare Ocular Tumor

“…The intracytoplasmic inclusions represent dilated cisternae of rough endoplasmic reticulum, which are theorized to have the secretory function of producing the mucoid stroma. 9,10,17 HISTOCHEMICAL AND IMMUNOHISTOCHEMICAL STUDY The conjunctiva myxoma cells stain positive for Alcian blue (Figure 4) with dissolution of the color after treatment with hyaluronidase, revealing cells that contain abundant hyaluronic acid mucopolysaccharides. 7,11,16 The cells also stain positively with mucicarmine and colloidal iron.…”

“…10,11 Immunostaining of conjunctival myxoma cells show extensive reactivity with vimentin ( Figure 5) and focal staining for a-smooth muscle actin. 7,9,17 Several authors 18,19 have presented a few cases that stained negative for smooth muscle actin. In 2012, Herwig et al 14 described a variant of conjunctival myxoma that stained positive for CD34.…”
