Angiolymphoid hyperplasia with eosinophilia involving the cubital nerve

Abstract

A tumor involving cubital nerve was resected and studied; it was classified as an angiolymphoid hyperplasia with eosinophilia (ALHE). Immunohistochemical and molecular study was done both to confirm the reactive nature of the process and rule out the presence of clonal T or B cell rearrangement. This lesion has been designated as epitheloid hemangioma [Coindre (1994) Ann Pathol 14:426]. Typically, ALHE occurs in the skin and the subcutaneous tissue, and extracutaneous involvement is rare. No cases of ALHE affecting a nerve have been described, but a case of Kimura's disease, the lesions of which have repeatedly been confused with ALHE, has been reported involving median nerve.
