Best Post of October 2018: Young adult with an iridic mass extending into the ciliary body
The next in our " Best of the Month " series comes from October 9, 2018:Melanoma markers were negative. Smooth muscle markers were positive. This case was determined to be an epithelioid leiomyoma. I didn ' t do electron microscopy to look for mitochondia, but it may well be what Ursula Schlotzer-Schredhardt et al. have called a mitochondria-rich epithelioid leiomyoma (Arch Ophthalmol, Vol 120, January 2002).

Young adult with an iridic mass extending into the ciliary body
Melanoma markers were negative. Smooth muscle markers were positive. This case was determined to be anepithelioid leiomyoma. I didn ' t do electron microscopy to look for mitochondia, but it may well be whatUrsula Schlotzer-Schredhardtet al. have called amitochondria-rich epithelioid leiomyoma(Arch Ophthalmol, Vol 120, January 2002).

Mesoectodermal Leiomyoma of the Ciliary Body
A 47-year-old woman is suspected of having a ciliary body melanoma (A). Histologic sections (B and C) show large ciliary body tumor composed of tumor cells in a fibrillar cytoplasmic matrix. Electron microscopy (D) shows a dense osmophiliic structure known as askeinoid fiber.Immunohistochemistry helped to confirm that this was a leiomyoma.(Case reported by J. Campbell et al. Ultrastruct Pathol 28:559, 1997.) (Source: neuropathology blog)

Uveal Melanoma: The Basics
The uvea of the eye is a vascular tunic comprised of the iris, ciliary body, and choroid. Located between the sclera and the retina, the uvea contains dendritic pigmented melanocytes which have the potential to give rise to malignant melanoma. Patients with choroidal melanoma typically present as adults with painless monocular vision loss, while a cataract or glaucoma may be the presenting feature of an anterior segment melanoma.Approximately half of patients with choroidal and ciliochoroidal melanomas eventually die from their tumors. Prognosis is better in cases localized to the iris, presumably because they are recogniz...

Vestige of a choroidal melanoma
Only melanin and melanophages remain in an enucleation specimen from a patient successfully treated with brachytherapy for choroidal melanoma. The eye was enucleated not because of the tumor, but because it was blind and intractably painful in the aftermath of treatment. (Source: neuropathology blog)

Can the Isis Iris Whitening Kit really change your eye color?
Et Moi muses…I’ve come across various dubious sources about changing or lightening the iris without contacts. Among the things that would change the eye color are: Doing a liver cleanse or a raw food diet, eye drops from Isis cosmeceuticals which contains msm and arbutin. Just wondering everyone’s opinion on this topic. Is it safe, ethical, or even effective? The Beauty Brains respond: Isis Cosmeceuticals does indeed offer an iris lightening kit. What they don’t offer is any proof that it works. How is eye lightening supposed to work? Iris color is determined mainly by the melanin content (the same ...
