Leiomyoepithelioma of iris pigment epithelium. 1987

Z Y Li, and M O Tso, and J Sugar

A 4-year-old boy had a jet-black, nodular lesion growing in his right iris. Detailed clinical and histopathologic studies of this unusual tumor showed the lesion to be derived from the anterior iris pigment epithelium. The tumor cells appeared to be benign and exhibited characteristics of both pigment epithelium and smooth muscle. We have called this tumor "leiomyoepithelioma of iris pigment epithelium."

UI	MeSH Term	Description	Entries
D007499	Iris Diseases	Diseases, dysfunctions, or disorders of or located in the iris.	Disease, Iris,Diseases, Iris,Iris Disease
D007889	Leiomyoma	A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the UTERUS and the GASTROINTESTINAL TRACT but can occur in the SKIN and SUBCUTANEOUS TISSUE, probably arising from the smooth muscle of small blood vessels in these tissues.

D008297	Male		Males
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy

D010857	Pigment Epithelium of Eye	The layer of pigment-containing epithelial cells in the RETINA; the CILIARY BODY; and the IRIS in the eye.	Eye Pigment Epithelium
D002675	Child, Preschool	A child between the ages of 2 and 5.	Children, Preschool,Preschool Child,Preschool Children
D005451	Fluorescein Angiography	Visualization of a vascular system after intravenous injection of a fluorescein solution. The images may be photographed or televised. It is used especially in studying the retinal and uveal vasculature.
