Abstract
Angiolymphoid hyperplasia with eosinophilia (ALHE), a rare benign proliferative tumor, mainly occurs in several countries in Asia and it is characterized by true vascular branching hyperplasia with infiltration of a large number of lymphocytes and eosinophils in the stroma. The present case report analyzed the clinical symptoms and fine-needle aspiration cytology, histopathological and immunohistochemical results of a patient with ALHE, and summarized the clinicopathological diagnostic features of the disease. To the best of our knowledge, this was the first study to comprehensively report the cytological, histopathological and immunophenotypic characteristics of ALHE, which could help clinicians fully understand this rare type of proliferative tumor.
