Fuchs adenoma
Pronunciation: FOOKS ad-eh-NO-mah
A benign hyperplastic lesion of the ciliary epithelium, typically appearing as a cystic or solid mass in the pars plicata region.
Full Definition
Fuchs adenoma is a rare, benign proliferative lesion arising from the nonpigmented ciliary epithelium in the pars plicata region of the ciliary body. These lesions typically present as translucent, cystic, or solid masses that may cause localized lens subluxation or cataract formation. Named after Austrian ophthalmologist Ernst Fuchs, these adenomas are usually unilateral and asymptomatic unless they reach sufficient size to cause mechanical complications. Differentiation from ciliary body melanoma requires careful clinical evaluation and sometimes histopathological confirmation, as the benign nature of Fuchs adenoma contrasts sharply with the malignant potential of melanocytic lesions in the same anatomical region.
Usage
Usage note: Always capitalize 'Fuchs' as it is an eponym; distinguish from Fuchs heterochromic iridocyclitis.
