{Abstract}: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare, benign, reactive vaso-proliferative condition in the dermal and subcutaneous tissues of the head and neck. A 28-year-old female presented with slow-growing painless swelling behind her left ear. FNAC revealed benign soft tissue neoplasm and histopathological examination after surgical excision revealed angiolymphoid hyperplasia with eosinophilia. ALHE origin has been variously attributed to prior trauma, hyperestrogenemia, infectious agents, atopy, reactive hyperplasia, and benign neoplasia. Retroauricular ALHE has been rarely reported. However, on the basis of our case report, it should be a viable differential diagnosis when large subcutaneous tumors of the head and neck are encountered. When big subcutaneous tumors of the head and neck are present, especially in females, a valid differential diagnosis for angiolymphoid hyperplasia with eosinophilia, a rare condition marked by dermal or subcutaneous endothelial cell proliferation, should also be considered.
