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.
