Angiolymphoid hyperplasia with eosinophilia: a case series and literature review

Purpose Angiolymphoid hyperplasia with eosinophilia is an uncommon chronic inflammatory condition of unknown etiology. Orbital and adnexal involvement findings are variable and often nonspecific. Methods and Result We report six patients with angiolymphoid hyperplasia of the orbit, their clinical and histopathological characteristics, and a review of previously published literature with this diagnosis between 1980 and 2021. Conclusion ALHE has definite histopathologic features but inconclusive radiological studies. The ophthalmologic findings of this entity overlap significantly with other similar variants and may be thought as equivalent lesions.
