Angiolymphoid hyperplasia with eosinophilia is a rare, benign, vascular proliferation that presents as dome-shaped, light-pink-to-red-brown papules or subcutaneous masses that lack distinguishing surface changes. The condition typically presents as a single lesion or multiple lesions that involve contiguous areas. The pathogenesis is poorly understood. Angiolymhpoid hyperplasia with eosinophilia has been associated with antecedent trauma, T-cell proliferation, infection, and hormone imbalance. This report details a case of widespread angiolymphoid hyperplasia with eosinophilia that flared while the patient was pregnant.
