Simultaneous presentation of Kimura disease and angiolymphoid hyperplasia with eosinophilia.

Kimura disease and angiolymphoid hyperplasia with eosinophilia are rare disease entities that can manifest as subcutaneous nodules, plaques, or papules of the head and neck, and less commonly the orbit and ocular adnexa. The merits of each entity have been debated with regard to whether they are truly individual or are separate points on a single spectrum. Current opinion favors the former. This clinicopathologic report of a patient who presented with a right lower eyelid mass with pathologic features consistent with Kimura disease and a left conjunctival mass with features consistent with angiolymphoid hyperplasia with eosinophilia poses a challenge to the notion that these are distinct conditions.
