Nodal angiolymphoid hyperplasia with eosinophilia.

Angiolymphoid hyperplasia with eosinophilia (AHE) is a benign process of unknown origin that tends to mainly affect the skin and subcutaneous tissue. A case is presented of AHE arising in a lymph node in the absence of dermal or subcutaneous involvement. The unusual location and histologic characteristics of the lesion prompted an initial diagnosis of Hodgkin's disease. Follow-up and review of the biopsy at a later date disclosed the characteristic features of AHE. The present case illustrates the ubiquitous nature of this process. AHE should be included in the differential diagnosis in lymph nodes showing effacement of their architecture by a diffuse, predominantly eosinophilic cellular infiltrate.
